Full textAbstract:
Construction is a project-based industry and construction supply chains generally work with a unique product in every project. Commonly, project organizations are reconfigured for each project. This means that construction supply chains are characterised by various practices and disjointed relationships, with the result that construction supply chain actors generally have transient relationships rather than long term risk sharing partnerships. A consequence of this is the lack of trust between construction clients, designers, main contractors and suppliers. Because the construction supply chain works as a disparate collection of separate organisations rather than as a unified team, the supply chain suffers from lack of integration. Knowledge flow in construction supply chains are hindered due to the reasons such as inadequate adaptation to collaborative procurement type projects, inadequate collaboration between the downstream and upstream supply chain, lack of interoperability of the design tools, lack of well structured SCM process and lack of well developed knowledge management applications. These characteristics of the construction supply chains are the main reasons for its low efficiency and productivity in project delivery. There is a need for the development of appropriate systems to ensure the effective diffusion of knowledge such that each actor of the supply chain adds value to the project delivery process. This is expected to result in the creation of knowledge chains in construction. It is believed that construction supply chain management (SCM), when integrated with knowledge management (KM), can successfully address the major problems of the industry The main aim of this research was to develop a framework to transform construction supply chains into knowledge chains . To reach this aim, the research first provided an overview of practices and issues in SCM across a range of industry sectors including construction, aerospace, and automotive industries. It discusses research and developments in the field of SCM and KM in construction industry, the key SCM issues with a knowledge flow focus, and the best practices from other industries to improve the construction supply chains. Furthermore, the results of the company specific and project specific case studies conducted in aerospace and construction industry supply chains are presented. These results include the key SC problems, key issues related to knowledge flow and the presentation of knowledge requirements of each supply chain actor. Following the data analysis process, a framework to transform the construction supply chain into a knowledge chain taking full cognisance of both the technical and social aspects of KM was presented. The main purpose of the knowledge chain framework was to enable construction bid managers/project managers to plan and manage the project knowledge flow in the supply chain and organise activities, meetings and tasks to improve SCM and KM throughout the supply chain in an integrated procurement type (PFI) project life cycle. The knowledge chain framework was intended to depict the knowledge flow in the construction supply chain specifically, and to offer guidance for specific business processes to transform the supply chains into knowledge chains. Finally, this research focused on the evaluation of the framework through industry practitioners and researchers. An evaluation of the Framework was conducted via workshop followed by a questionnaire comprising industry experts. The findings indicated that adoption of the Framework in construction project lifecycle could contribute towards more efficient and effective management of knowledge flow, standardisation and integration of SCM and KM processes, better coordination and integration of the SC, improved consistency and visibility of the processes, and successful delivery of strategic projects. The overall research process contributed the construction research in many perspectives such as introduction of knowledge chain concept for construction supply chains; comparative analysis of the SCM practices in different industry sectors, identification of best practices for construction supply chains, better demonstration of the maturity level and critical factors of the SCM within the construction industry, demonstration of the KC framework which integrates the supply chain process and knowledge sharing within a single framework which covers all the recent trends in the construction industry like collaborative procurement route projects, creation of better integrated SCs, applications like off site construction and BIM where all supply chain management and knowledge management should take place.

Full textAbstract:
Practitioners operating within the construction industry are faced with considerable challenges and difficulties when attempting to manage their supply chains and obtain value for money. This work highlighted that in response to these problems, recent industry reports and academic literature have called for the adoption of more sophisticated 'best practice' approaches including proactive integrated supply chain management to provide significant commercial benefits and alter construction's supposed obsolete practices. This advice has been contested by a number of academic writers, who are more sceptical about whether generic approaches can be claimed to be 'best practice', without providing a convincing and robust methodological justification. In response to this ongoing debate, and following the power and appropriateness school of thought, this thesis developed testable hypotheses regarding the ability of construction clients and contractors to implement specific sourcing approaches under particular external power circumstances, and the impact that internal capabilities has on the ability of buyers to effectively implement proactive or reactive sourcing approaches. In testing the hypotheses, it has been demonstrated that the implementation of proactive approaches to upstream supply management are not appropriate (or possible) in all supply chain circumstances and power structures and therefore, reactive sourcing approaches may be the most effective supply strategy for some buyers, or indeed their only option.

Purpose The purpose of this study is to understand the reason behind why it occurs a large number of pickups each year in the construction industry. In the case company alone, it occurs 160 000 pickups per year and an estimated loss of 50 MSEK. This thesis will try to investigate and explain why the pickups occur, and also what the underlying factors are that could influence the number of pickups. Methodology The data in the thesis was collected from semi-structured interviews with eight employees within the case company. We chose to interview four employees from the construction department and four employees from the construction service department. The reason to that was that different departments works differently to each other, and we wanted to know what the differences were. The employees all had management or supervisor positions and were based in different geographical areas. In the thesis, we applied a mix of content analysis and grounded analysis method. Findings The findings made during the thesis, were that the different departments work with pickups very differently when comparing to each other, one department had almost all their supplier contact at the beginning of the projects and didn’t require more supplier contact during the production. While the other department, due to their nature required regular supplier interaction which created an increase number of pickups. The main reasons behind the pickups were to inadequate planning and the organizational culture. Conclusion The conclusion provides areas where the company can improve on regarding the pickups and recommendation of how the case company can reduce the number of pickups, based on the gathered data and the theoretical frame of references. The recommendations were: enhance the supplier relationship, re-evaluate the contracts with the suppliers, education regarding planning and work-method.

Full textAbstract:
Environmental pollution and climate change have become one of the greatest challenges of the 21st century, which have forced governments and businesses alike to assess the environmental impacts of their activities. Among the sectors, construction is the single largest contributor of global carbon emissions, resource, water and energy consumption, and landfill waste. With environmental implications expected to be even greater in the future due to increasing urbanisation and the consequent increase in construction activities, curtailing the negative environmental impacts of the sector or greening the construction sector, therefore, has become critical. Unfortunately, any limited efforts to date to address these concerns have been less fruitful as most of these efforts have been largely fragmented and disjoint, addressing issues in an ad-hoc, standalone manner such as green design, green purchasing, green construction or environmental management systems; or management issues such as ‘drivers’ and/or ‘barriers’ affecting these specific green practices; or specific performance implications from these green practices such as environmental and/or financial performance. This lack of holistic orientation also carries the risk that practitioners and policymakers could mistakenly be addressing the wrong issues and neglecting aspects that have more significance in greening the sector. Given the environmental consequences of a construction project are typically dispersed across the different stages in the supply chain, i.e. from design through to end-of-life, and that several stakeholders, each with their own conflicting interests, are involved in the different stages of the construction supply chain, greening the sector, therefore, requires a supply chain wide focus, inclusive of all key stages and stakeholders (Developers, Architects/Consultants, Contractors and Suppliers). Therefore, the application of green supply chain management (GSCM) or incorporating environmental concerns into supply chain management (a systematic and integrated approach) makes perfect sense for greening the construction sector. GSCM contributes to greening by promoting supply chain-wide implementation of efficient and effective green practices by means of managing the ‘drivers’ and ‘barriers’ affecting its implementation to achieve the desired environmental performance along with short-term economic/cost performance and long-term organisational performance. This formed the focus of this study, wherein, it explores the application of GSCM in greening the construction sector. The study also explores the impact of firm size and ownership on GSCM, because, given the inherent complexity of the construction supply chain, i.e. it comprises of hundreds of firms with varying size and ownership, a comprehensive greening of the construction supply chain would not be possible without managing the impact of size and ownership on GSCM. Finally, given that GSCM understanding would be of limited value unless accompanied by general principles (theories) that inform wider application, the study utilises several established and emerging management/organisational theories to underpin the multifaceted reality of GSCM. In short, each of these GSCM aspects, i.e. green practices, green drivers and barriers, and green performance; and their interrelationships; and the impact of firm size and ownership on GSCM are investigated as separate research questions in this thesis. UAE is carefully chosen as the research setting for this GSCM study mainly because it gives an exemplary opportunity to understand the competing actions required from governments and construction sector firms to lessen the environmental impacts associated with the rapid urbanisation and economic modernisation. Specifically, on one side, the UAE construction sector is growing at more than 9% per annum, while on the other side several green initiatives are considered by practitioners and policymakers to reduce its environmental burden on the country. Therefore, the related findings are expected to be more practically relevant to comprehend the challenges and opportunities in the application of GSCM. A pragmatic, multi-methodology, sequential exploratory approach (i.e. the qualitative investigation followed by quantitative investigation) was employed to comprehensively answer the research questions. For the qualitative investigation, both semi-structured interviews (to explore and define each GSCM themes/sub-themes), and focussed, in-depth interviews (to gain operational/implementation level understanding) were employed. For the quantitative investigation, a structured country-wide survey was employed. The findings derived from the multiple methods (interviews and survey), were then combined to develop a comprehensive picture on the various facets of GSCM in relation to greening the construction sector. With regard to the findings, the important/relevant core green practices (or environmental activities/initiatives undertaken across each of the distinct functional stages of the supply chain) identified for greening the construction sector include green design, green purchasing, green transportation, green construction/manufacturing and end of life green practices, whereas the important/relevant facilitating green practices (or activities/initiatives undertaken to build internal environmental resources and capabilities) identified for greening the construction sector include environmental management systems (EMS) and ISO 14001 certification, cross-functional integration, environmental auditing, environmental training and green-related research and development. The extent of implementation of these practices, in general, was found to be the highest among Suppliers, moderate among Architects/Consultants and Contractors, and lowest among Developers. The important/relevant external green drivers (external forces/pressures that coerce firms to implement green practices) identified include government green-related regulation, supply chain stakeholder pressure, competitor pressure and buyer/end-consumer pressure, whereas internal green drivers (internal forces/pressures that motivate firms to implement green practices) identified include environmental commitment of firms, enhance reputation/brand image, to reduce costs and to enter foreign markets. The relevance/importance perceived by stakeholders shows that all stakeholders except Developers are more motivated internally than externally to engage in green practices. On the other hand, the important/relevant external green barriers (external forces that hinder or restricts firms from implementing green practices) identified include shortage of green professionals, shortage of green suppliers, tight and inflexible stakeholder deadlines and lack of stakeholder collaboration, whereas internal green barriers identified include high cost of implementation and lack of knowledge and awareness. The relevance/importance perceived by stakeholders shows that Developers and Suppliers perceive internal barriers more than external, while Architects/Consultants and Contractors were found to perceive external and internal barriers to be more or less the same. The study also identified several important/relevant performance measures to capture environmental, economic/cost and organisational performance that firms could operationalise to capture the benefits of green practices. With regard to actual improvement in these performances, all three performances were found to be relatively lower for Developers, while moderate to high for other stakeholders. With regard to the relationship between GSCM aspects, the extent of the impact of green drivers on green practices was found to far exceed the impact of green barriers on green practices, which self-explains the moderate extent of implementation of green practices across stakeholders. Moreover, it was found that both core and facilitating green practices have a significant and positive impact on three dimensions of performance across stakeholders, and the strength of impact, in general, ranged from moderate to high. Furthermore, facilitating green practices was found to have a strong and positive impact on core green practices. Finally, firm size and ownership was found to have a significant impact on the various GSCM aspects.The study provides practitioners (across all stakeholders) with a potential stock of core and facilitating green practices that they could implement as well as potential performance measures they could operationalise in their respective firms. Also, it helps them to gauge the green drivers and barriers affecting their green practices implementation.

Soe, Yadanar. "Construction supply chain risk management framework for construction projects : case studies in Myanmar." Thesis, University of Birmingham, 2017. http://etheses.bham.ac.uk//id/eprint/7631/.
Full textAbstract:
This research focuses on developing a Construction Supply Chain Risk Management (CSCRM) framework that can be adapted by developing countries to help construction projects make better use of materials procurement in their organisations, and to improve construction project management by effectively controlling the project to avoid project cost overruns. The research is conducted in Myanmar and all the companies studied, including the case-studies, are operating in Myanmar. The proposed CSCRM framework includes the plan, resources, process and control model part. The model suggests the development of close relationships with various stakeholders of the project for better use of the Risk Management Model. Without a proper CSCRM framework, a construction company in Myanmar can encounter a cost overrun of about three times the estimated total cost. However, the use of the proposed CSCRM framework can minimize the cost overrun by amounts of two times the total project cost. The results of case studies in three construction companies in Myanmar confirm that the proposed model is effective in managing the supply chain of construction projects in Myanmar, with effective mitigation of cost overrun risks and maximization of competitive advantages of the company.

Full textAbstract:
The construction industry is known for its inefficiency, with projects exceeding budgets and not completing on time. It is claimed that these problems stem from the industry’s characteristics and affect the project’s success. Research has increased within the field of construction supply chains and construction supply chain management as a way to increase coordination and improve project performances. However, the industry and the companies within have a long way to go before construction supply chain management is integrated. This study presents problems that are manageable for a general contractor and what enabler can be implemented to facilitate the integration of construction supply chain management and coordination. The study investigates a Swedish project and its current situation, where the collected data from interviews belong to either people, processes, or contexts. The study identifies 22 problems and 21 enablers from interviews, literature, and frameworks. Early on in the study, it is noted that problems are linked and affect various disciplines. Consequently, if one problem arises it affects other disciplines. Therefore to understand the problems origin and connections will the opted analysis provide their association to each other and their belonging to either the construction or supply process. Based on the belonging, the problems are sorted if they are considered manageable for a general contractor and relate to either organizational efforts, management of the information flow, or relationships. The study also provides proposed applications for information and communication technology. Furthermore, initial steps towards integrating construction supply chain management for a general contractor this is done by initiating ’supply chain integration’ and develop integrating processes, products, and services. It is recommended that this should be done by mapping the current state of the supply and construction process, identifying individuals who are familiar with supply chain methods, and involve them in works for improvement. The second step is to develop an organizational and team culture that is open for change and supports integration. Once the culture has been established, more effort and resources can be added towards building relationships and develop construction supply chain collaborations. Proposed enablers are among several to develop selection criteria to determine suppliers and subcontractors and adapt resources such as time and money accordingly. Since subcontractors are responsible for the supply process, it is recommended that goals and evaluation criteria for these actors should be developed based on supply chain performances and form the basis for evaluating subcontractors. This study confirms previous studies where the general contractors’ ability to cooperate and their practices are affected by the owners’ demand and preferred methods. Therefore it is required that the general contractor’s ability to adapt accordingly is increased. Consequently, the need for new management principles that are highly adaptive and easy to use is demonstrated. The compiled results indicate an imbalance of responsibilities and a lack of ownership for changing the industry and showing the need for new management principles. Which leaves the question, who is responsible for changing the industry? Even though this is a complex question, as indicated in the study, there are actions that a general contractor can take to integrate construction supply chain management and increase coordination.

The poor trust culture in the construction sector is often considered an inhibiting factor to collaboration success in the United Kingdom (UK) despite reform efforts. Numerous reform initiatives tend to have focused on improvements in client and main contractor aspects of construction supply chain relationships, prompting claims that failure to integrate subcontractors, suppliers and consultants into collaborative arrangements remains a major shortcoming. Main contractor and subcontractor relationships therefore continue to be typified by such problems as late payments, charging fees to tender for work, award of contracts based on cheapest price rather than best value, negative margins and demand of retrospective discounts and cash rebates; all of which negatively impact on trust. Some main contractor organisations however, continue to embed supply chain management practices as a strategy for levering value from subcontractors. Such collaborative practices and their implications for inter-organisational trust development, and indeed overall project outcomes, have nonetheless received limited attention in construction management research, raising significant questions on the empirical basis for their implementation. This research was thus undertaken to investigate strategic supply chain management practices adopted by UK main contractors and its implications for inter-organisational trust development during projects. The study adopts a multiple case study design so as to unravel complex subtleties of inter-organisational trust development in the main contractors’ supply chain during projects. With four purposefully selected UK main contractor organisations that had implemented strategic supply chain management, data was gathered through a supply chain workshop, semi-structured interviews, passive observations and documentary analysis. From analysis of the data, it was revealed that strategic supply chain management practices of the main contractors were instrumental for trust manifestation across cognition, system and relational based dimensions. These practices served as constitutive elements of face-to-face interactions through which inter-organisational trust developed, whilst providing the institutional framework to which respective supply chain parties directed their psychological expectations. These findings highlight the importance of maintaining a core of subcontractors from which the main contractor can leverage long-term value irrespective of economic climate. This can be achieved by adequately prioritizing relationally trusted subcontractors for sensitive and high risk work packages whilst ensuring that strategic supply chain management principles can be used to engender impersonal (cognition and system-based) trust dimensions amongst other subcontractors used on a project. Accordingly, a supply chain management oriented framework for engendering inter-organisational trust during projects has been developed based on the study findings and evaluated through semi-structured interviews with selected target participants. This framework does not only provide a systematic and coherent approach for implementing or benchmarking strategic supply chain management in a main contractor’s organisation, but can also be used to prioritize and promote different trust dimensions and their associated behavioural consequences on projects, depending on perceived work package risks.

Much research work has assessed the construction process and discovered that the process is ineffective and besieged with problems. Analysis of these problems has shown that a major part of them are related to the state and workings of the supply chains. Prior research justifies that waste and problems in construction supply chains are extensively present and persistent. This anomaly may be ascribed to the nature of the industry. Horizontal integration that is common place in the construction industry tends to fragment the supply chain, resulting in an unstable production environment occasioned by high unpredictability, much rework, low profits and eventual low level of value creation in the process. Therefore, an increased level of integration of interfaces and processes has been canvassed. The purpose of supply chain management is to achieve the expected increased level of integration of the whole supply chain. Supply chain management is a concept that has flourished in the manufacturing industry through Just in Time production and logistics. Supply chain management represents an autonomous managerial tool, though still largely dominated by logistics. Supply chain management has long been advocated as a means of improving the performance of supply chains in construction. This research study reports on an investigation into the impact of supply chain management on value creation in the South African construction industry. The research discovered that collaborative working is already in the industry and contractors consider supply chain management important for project success. Here construction supply chains were approached from the relationship view point. All issues are encouraged to be viewed and resolved in the supply chain from the relationship perspective.

Full textAbstract:
Construction supply chains encompass the flows of information, materials, labour, plant, equipment and temporary work, which originate from the different parties, viz., main contractors, suppliers, subcontractors and clients/architects. Any problems with these flows will eventually disrupt the project performance. The primary aim of this research was to gain a comprehensive understanding of the impact of supply chain management practice on construction project performance. The research methods adopted comprised: preliminary investigations, a main survey and the development of simulation models. The preliminary investigations were carried out by interviewing members of the construction industry and visiting two medium-sized building projects over a period of 6 months. The main survey was intended to collect data required for developing the simulation models. They were developed using Pertmaster Risk ExpertM software, which allows supply chain delays to be applied on a CPM network of a typical medium-sized building project of 300 days duration. The results of the simulation showed that when all work was carried out by the main contractor and all supply chain delays were applied, the project's median delay was 67 days (equivalent to 22% of the project duration). It was learnt that problems in material flow caused the biggest impact on the project, followed by labour flow, information flow, and `plant, equipment and temporary work' flow. Among the problems in material flow, the biggest impact was due to difficulties in finding materials. When subcontractors were used for the activities that are normally subcontracted, there was a significant reduction of the median delays from 67 to 37 days (equivalent to a 45% reduction). These findings are an important measure of how much supply chain delays may impact on project performance and suggest that problems related to the supply chain in construction are likely to generate significant disruption.

This thesis examines the effect of reverse logistics practices on supply chain performance in the construction sector that adversely impacts the environment. Mixed-method was adopted to examine the role of reverse logistics practices, environmental impacts of reverse logistics strategies, and the effect of reverse logistics on supply chain performance. Results revealed that waste management is the mere focus of reverse logistics in the industry, reuse is environmentally the best option, and reverse logistics favourably impact most of the performance criteria. The study provided recommendations for strategic decision and policy making for successful reverse logistics at macro, meso, and micro levels.

Full textAbstract:
Idag har bygg- och anläggningsbranschen låg produktivitet och icke-värdeskapande aktiviteter uppgår till 30- 35% av projektets produktionskostnad. Genom en effektiv logistikhantering ökar produktiviteten och minskar slöserier och därmed byggkostnaden. Studien fokuserar på anläggningsbranschen då det i dagsläget är brist på forskar- och grundutbildad personal inom anläggning vilket även speglar sig i antalet vetenskapliga artiklar som publicerats inom anläggning. Det finns därför ett syfte i att skapa en större teoretisk förståelse för anläggningsbranschen. Studiens syfte har varit att undersöka planeringsfasen för logistik i ett anläggningsprojekt och ta fram en konceptuell logistiskmodell för ett anläggningsprojekt. I anläggningsprojekt är det ofta problem med stora projektytor och svåråtkomlig terräng men det kan även vara problem med trånga utrymmen runt projektet. Dessutom innebär projekt i anläggningsbranschen ofta omfattande hantering av massor. I fallföretaget finns det ingen tydlig logistiskmodell som efterföljs och man har svårt att se fördelarna med att använda logistik. Målet med studien är att genom den konceptuellt framtagna logistiskmodellen få ett standardiserat arbetssätt och därmed effektivisera produktionen och minska kostnaderna. Dessutom är målet att bidra till forskningen om logistik i anläggningsbranschen. Explorativt forskningssyfte har använts för att uppfylla studien syfte. Detta för att skapa en större förståelse för logistik i anläggningsbranschen. Forskningsansatsen är deduktiv i och med att logistikmodellen har utvecklats från befintlig teori, och testas empiririsk i fokusgrupper. En kvalitativ strategi har tillämpats på denna studie då fokus är på att skapa en djupare förståelse och ge möjlighet till anpassning beroende på vad som hittas i datainsamlingen. De datainsamlingsmetoder som har använts är litteraturstudie, intervjuer, fokusgrupper och kvalitativ sekundärdata. För att säkerställa studiens kvalitet användes triangulering men även granskning av handledare och personer som deltog under fokusgrupper och intervjuer. Den konceptuella logistiskmodellen består av sjutton komponenter som innehåller aktiviteter/verktyg och förutsättningar som krävs för en effektiv logistikhantering i anläggning. Med hjälp av denna modell kan företag utvärdera vilka logistiska aktiviteter som bör genomföras i ett anläggningsprojekt samt se vilka förutsättningar som krävs. I fallföretaget genomförs inte alla dessa aktiviteter och det är vissa viktiga förutsättningar som fattas. Fallföretaget rekommenderas att upprätta en utbildning om logistik, skapa en tydligare logistikorganisation och ta fram standardiserade processer för logistik.Today the construction industry has low productivity and the waste is about 30-35% of a project's production cost. By using an efficient logistics management the productivity will increase, which will reduce the waste and production cost. This thesis focuses on the construction industry with focus on civil engineering projects. It is a lack of research that focus on civil engineering projects, which is reflected in the number of scientific articles that has been published in this area. Hence, this is a reason to research further about civil engineering projects in order to create a bigger theoretical understanding. The aim of this thesis was to investigate the planning process with focus on logistic and to develop a conceptual logistic model for civil engineering projects. In civil engineering projects, companies often have problem with large project areas and difficult terrain around the project. But there can also be problems with narrow spaces. In addition to this, civil engineering projects often have to manage a large amount of masses. The company that this thesis has been conducted at has no clear logistic model that the staff follows, and they find it difficult to see the benefits with logistic. The aim of this thesis is to develop a conceptual logistic model that generates a more standardized work method that streamline the production and reduce the costs. In addition, the goal is also to contribute to research on logistics in the construction industry that focus on civil engineering projects. To fulfill the aim of the thesis an exploratory research have been used. This to create a greater understanding of logistics in the construction industry with focus on civil engineering projects. The research approach is deductive because the logistic model has been developed from existing theory and been empirically tested by using focus groups. A qualitative strategy has been applied on this thesis since the aim is to create a deeper understanding and a qualitative strategy gives an opportunity to adjust the thesis depending on what is found in the data collection. The data has been collected through a literature study, interviews, and focus groups. Data has also been collected from qualitative secondary data. During the focus groups the conceptual logistic model, which are based on the data from theory, interviews and empirical data, was tested. In order to ensure the quality of the thesis, triangulation was used. But the thesis was also reviewed by the supervisors and the persons who participated in the focus groups as well as the interviews. The conceptual logistic model consists of seventeen components that contains activities/tools and conditions that are required for an efficient logistics management. With this model the company that the thesis has been conducted at, but also other similar companies, can see what logistics activities needs to be done but also see what conditions are required. The company where the thesis has been conducted at does not perform all of these activities and some important conditions is not fulfilled. The company is recommended to educate in logistics, make a clear logistic organization and develop standardized processes for logistics.

Full textAbstract:
The construction industry is associated with problems such as low productivity and high costs. This has been highlighted in several government-funded reports in both Sweden and in the UK during the course of over two decades. The construction industry is a large industry sector employing hundreds of thousands and a large contributor to a country’s GDP. The problems therefore have a large impact on society. Some of the problems are rooted in the organizational structure of the construction industry. Compared to other manufacturing industries, the construction industry is organized in temporary organizations. The temporary organizations cause temporary supply chains, fragmentation among construction industry actors and adversarial relationships between those actors. Partnering has been but forward as a solution to overcome the temporariness and the adversarial relationships in the construction. Another solution to mitigate the problems suggested in the reports is supply chain management (SCM). Both concepts have been taken from the manufacturing industries and partnering has been more successful compared to SCM in the construction industry. In the construction industry the progress towards SCM has focused on logistics. In recent years dedicated third-party logistics (TPL) solutions have emerged in the Swedish construction industry, where a company is hired to manage the logistics in a construction project. The purpose with the research presented in this licentiate thesis is to explore how client initiated TPL solutions and partnering can be facilitators for SCM in the construction industry. Being a new phenomenon in the construction industry TPL solutions provide a logistical competence not necessarily included in a traditional construction project. Therefore, TPL solutions are of particular interest when studying the realization of SCM in the construction industry. In the process of realizing SCM in the construction industry, the construction clients have been put forward as having a crucial and important role. The clients are the initiator and funder of construction projects and as such the client can influence the course of a construction project. Therefore, it is of interest to study how the client can take an active role in this process. Initiating a TPL solution in a construction project is one way for a client to take an active part in the realization of SCM in construction. However, in order to study how clients can take an active role towards the realization of SCM in the construction industry, there have to be an understanding of how SCM is to be adopted to the construction industry context. SCM that derives from the manufacturing industry is designed to be used in long-term relationships with permanent organizational structures. The construction industry on the other hand is associated with short-term relationships and a temporary organizational structure. Partnering that is designed to mitigate the temporariness and establish long-term relationships have been quite successful in the construction industry, and could therefore be used as a facilitator for SCM in construction. To study the use of client initiated TPL-solutions in construction and the realization of SCM in the construction industry the following research questions have been addressed: RQ1: To what extent can a third-party logistics solution be a facilitator for client driven SCM in the construction industry? RQ2: How will upstream and downstream tiers be affected when a thirdparty logistics provider is used in a construction project? RQ3: How can partnering be used a mean to facilitate the realization of SCM in the construction industry? To answer the research questions two main methodologies have been used; case study for the empirically grounded research and conceptual studies for the analysis of the case studies as well as for comparing the two concepts of partnering and SCM. All questions have been grounded in literature and previous research. The findings of this research is therefore grounded in both theory and in practice. The main findings of this research is that TPL solutions are not a quick fix for realizing SCM in the construction industry. However, if used right a TPL solution can be an effective tool to address logistical issues in a construction project and to establish an interface between the supply chain and the construction site. By initiating a TPL solution the client addresses the importance of logistical competence in a construction project. A TPL solution does not have a purpose of its own; a TPL solution is a service function to the construction project, providing expertise on logistics management. There are also a number of driving forces and concerns that have been identified, if they are addressed prior to a TPL solution is implemented, the likelihood of its success will increase. Furthermore, both partnering and SCM rely on high trust and share several key components and issues that have to be addressed. Partnering on strategic level with several suppliers included can even be hard to distinguish from SCM. Wherefore, partnering is considered a facilitator for the realization of SCM in construction. By addressing the necessary issues in both concepts a good foundation for SCM is established.QC 20181004

Full textAbstract:
Supply chain management is one of the newest and most fashionable managerial concepts to be sponsored by those organisations responsible for setting the change agenda in the construction sector. Its success elsewhere, its promise of productivity improvement and 'best practice' pedigree form the basis of arguments for its adoption in the construction sector. There are a number of assumptions that underpin this argument that are largely ignored by the promoters of such change and the construction management research community. Most notably, the transferability and utility of supply chain management in the context of organisations competing in the construction sector. However, it is argued in this thesis that these arguments fail to engage with the recursive relationship between context and practice. Managerial practice does not exist in a vacuum. The research therefore sets out to test the theory of supply chain management in the construction sector. In doing so, the research approach is informed by and draws on contextual approaches that are highly sensitive to the recursive relationship between context and practice. A multiple case study research strategy was chosen that sought to provide explanations for how practitioners make sense of supply chain management in the context of their organisations and forms the basis of theory testing. These explanations also provided a wealth of empirical evidence to test the assumptions that underpin calls for change in the construction sector. It is concluded that supply chain management does not make sense in the construction sector and that calls for its adoption lacked intellectual rigour and were indeed acontextual.

Full textAbstract:
With the requirements of regulatory bodies, customers and business partners, Chinese
construction sector have been driven to imitate and implement green Supply Chain
Management (SCM) for their companies, to gain economic benefits and to become sustainable.
This research aims to investigate and identify green SCM practices that can potentially help
improve environmental and economic performance of organisations in Chinese construction
sector, leading to improved sustainability. With data collected from 103 companies in Chinese
construction industry, an exploratory factor analysis was conducted to derive groupings of
green SCM pressures/ drivers, practices and performance. Analysis of variance and t-tests were
introduced to assess the variations in green SCM pressures/drivers, practices and performance
for different sized enterprises and different industry sectors. Using regression analysis,
relationships between green SCM pressures/ drivers, practices and performance were examined.
To gain in depth insight into the causal relationship among factors obtained from the empirical
studies, two case studies were conducted. This research also explored and identified gaps
existing between green SCM in Chinese construction industry and British construction industry
through benchmarking exercise. The main findings from the empirical studies result reveal that:
1) Regulations and internal factors are considered as important green SCM drivers and
pressures. Medium and large sized Chinese companies face higher regulatory pressures than
small firms. 2) Case studies confirm that green SCM is not a new concept in Chinese
construction industry. Companies have begun to change their focus from improvement in one
supply chain entity to the entire supply chain. 3) Chinese construction companies seem to be
more matured in their adoption of green procurement practices than companies in building
material sector. 4) There is not any significant relationship between green SCM practices and
performance since most of the enterprises just initiate implementing green SCM practices.
Medium and large sized companies in Chinese construction industry have better economic
performance than small sized companies. The results from the benchmarking exercise against
British construction sector reveal that: 5) Green SCM implementation in British construction
sector is more comprehensive and effective because customers and suppliers in Britain have
more proactive involvement in adopting green SCM practices.

Full textAbstract:
For decades, Army Engineers have utilized the systems of the Critical Path Method (CPM) and multi-level Gantt chart planning system for its construction projects. While these methods are well accepted, they are not without their flaws. Research and literature in project management has given weight to several viable alternative options to planning projects. One such option, Critical Chain Project Management (CCPM), was developed to address the flaws of CPM by offering a holistic approach to project management based on strict resource control and the use of time buffers. This method attempts to eliminate multitasking and procrastination that can plague efficiency and offer managers more flexibly on tasks that otherwise had no leeway. CCPM may give project managers more flexibility and control while at the same time shortening the overall length of a project, saving time and money.
The purpose of this thesis was to address the time saving and resource management benefits of utilizing CCPM over CPM and analyze the viability of those benefits being applied to U.S. Army Corps of Engineers construction project planning. Through the use of surveys of Army Engineer project supervisors, several key factors that cause delays because of CPM were identified and rated. The validity of CCPM based solutions to the same issues were also assessed by Army project supervisors in the survey. Analysis of the survey results indicated that CCPM may offer solutions to major issues that Army project supervisors face.

Full textAbstract:
Common problems at the construction site are logistics problems regarding material delays, handling and transfers. At present, there is a very low use of digital tools in the construction industry. The construction sector has low productivity and high costs, and one reason for this is that the industry has not adopted new technology to streamline its processes. The purpose of this degree project is to investigate how BIM (building information modeling) can facilitate logistics work (for example, the supply of materials) at the construction site. This by first investigating what problems arise in production and then how BIM is used to mitigate these problems. Thus, come up with suggestions for a working method and routines to increase the use of BIM to facilitate logistics and supply production with materials. The aim of this thesis is to identify contractor and suppliers needs and to suggest improved working methods with BIM in order to improve logistics in the production phase. These are the selected research questions: What material flow information is important to make logistics work during production? How can BIM be used to manage material flow information and thereby improve logistics? The work carried out with a qualitative methodology where the questions asked were open and open-ended questions. Furthermore, the author used a semi-structured interview method. This study are based on five interviews and the respondents interviewed were from both Norrköping and Kalmar. The results indicate that the information needed for production to flow in a good way and get the logistics to work is information regarding deliveries should be close to the Just In Time principle. This means that the right material is delivered at the right time in the right place. Because much of the craftsman day is spent waiting for materials. The need of the supplier is to get an order with enough information. This needed to report is an early delivery plan to avoid waiting for materials and supplying production with materials. The study also shows that BIM is used as a support to facilitate logistics at the construction site through the right model that has a structure that works throughout the process. It is important to enter the correct information regarding quantity, dimensions and number. Furthermore, it can be used by connecting the 3D model to time schedule to plan when it suits best with deliveries and optimize with Just In Time deliveries. Thus, the model is also used when planning workplace disposition plans. Keywords- BIM, construction logistics, Just In Time, waste, supply chain managementVanligt förekommande problem på byggarbetsplatsen är logistikproblem gällande materialförseningar, hanteringar och förflyttningar. I dagsläget är det väldigt låg användning av digitaliserade verktyg inom byggbranschen. Byggsektorn har låg produktivitet och höga kostnader, en anledning till detta att branschen inte använder sig av ny teknik för att effektivisera processerna. Syftet med examensarbetet är att undersöka hur BIM kan användas för att minimera logistiska problem på byggarbetsplatsen (exv. materialförsörjningen). Detta genom att först undersöka vilka problem som uppstår i produktionen, sedan se över hur BIM kan nyttjas för att mildra dessa problem. Därmed komma på förslag på arbetssätt och rutiner för att öka användning av BIM för att underlätta logistik och materialförsörjning av produktionen. Målet är att identifiera entreprenörer och leverantörers behov samt föreslå förbättrade arbetsmetoder med BIM för att förbättra logistik i produktionsfasen. Dessa är de utvalda forskningsfrågorna: Vilken materialflödesinformation är viktig för att logistiken ska fungera under produktionen? Hur kan BIM användas för att hantera materialflödesinformation och därmed förbättra logistiken? Arbetet utförs med en kvalitativ metodik där frågorna som ställdes var öppna och öppenriktade frågor. Vidare använde författaren sig av semistrukturerade intervjumetod. Denna studie baserades på fem intervjuer och respondenter som intervjuades var både från Norrköping och Kalmar. Resultatet indikerar att den informationen som behövs för att produktionen ska flöda på ett bra sätt och få logistiken fungera är information gällande leveranser ska vara nära Just In Time principen. Med det menas att rätt material ska levereras på rätt tid på rätt plats. Eftersom stor del av byggarbetarnas dag går åt att vänta på material. Det som behövs för leverantören är att få beställning men tillräcklig med information. Det behövs redovisas är en tidig leveransplan för att undvika väntan på material och försörja produktionen med material. Studien visar även att BIM kan användas som ett stöd för att underlätta logistiken på byggarbetsplatsen genom rätt modell som har en struktur som fungerar genom hela processen. Det är viktig att mata in rätt information gällande mängd, mått och antal. Vidare kan användas genom att koppla 3D- modellen till tidsplanering för att planera när passar det bäst med leveranser och optimera med Just In Time leveranser. Därmed kan modellen även användas vid planering av arbetsplatsdispositionsplanen. Nyckelord: BIM, bygglogistik, Just In Time, slöseri, supply chain management

Full textAbstract:
There is an increasing number of construction products that are manufactured globally through complex supply chains. The results of this is that quality requirements are increasing and the construction industry look towards ways to reassure the sustainability of the materials in their supply chains. The aim of this study is to explore how the new blockchain technology may be used to meet today´s and future requirements of the construction industry and analyze the potential consequences of using the technology. Our work examine how the blockchain technology can support supply chain transparency and material traceability. To explore and analyze how the technology may affect the supply chain of a specific material a case study has been carried out. The task has been focused on how a specific material is handled throughout a suppliers supply chain, from where it originates until final use by a contractor. A hypothetical supply chain has been set-up and analyzed in terms of transparency, traceability and the potential consequences of using the blockchain technology. We have specifically focused on how the blockchain system could be set-up, who should own the blockchain system and what are the sustainable aspects of using blockchain. The conclusion is that blockchain technology can improve the transparency throughout the entire supply chain. However the need for a complementary technology is needed in order to handle all the problems with traceability. One example of this complementary technology is RFID tagging. Furthermore, some of the consequences that has been identified are; it improves the way to handle supply chain documentation, the reputation of the industry improves, the possibility to remove third party organs increases.Med ökat antal byggmaterial som tillverkas genom globala komplexa försörjningskedjor ökarkvalitetskraven inom byggbranschen samt behovet att säkerställa hållbarheten hos dessamaterial.

Detta arbete undersöker följaktligen hurblockkedjeteknik kan stödja transparens och spårbarhet i leverantörsledet.För att analysera hur tekniken kan påverka en typ av byggmaterial har en fallstudie utförts isyfte att kartlägga ett leverantörsled. Fallstudien har fokuserat på hur materialet hanteras, fråndess ursprung tills att det anländer till byggarbetsplatsen. En hypotetisk leverantörskedja harkonstruerats och analyserats i termer av transparens, spårbarhet och vilka olika konsekvenserdet kan medföra. Vi har speciellt fokuserat på hur blockkedjesystemet kan konstrueras, vemsom ska äga systemet och hållbara aspekter.Slutsatsen är att blockkedjeteknik kan öka transparensen genom hela leverantörsledet. Detfinns emellertid ett behov av komplimenterande teknik att lösa spårbarhet. Ett exempel pådenna komplimenterande teknik är RFID taggning. Slutligen har ett antal konsekvenserfastställts vid ett användande som är; hanteringen av dokumentationen förbättras, ryktet inomindustrin förbättras och möjligheten att ersätta tredjepartsorgan ökar.

Full textAbstract:
Purpose: External logistics coordination was decided after a long procurement process while parts of the project Vallastaden already started construction. The external logistics company creates and implements a logistics solution in a short time. The municipality has no formal connection requirements on developers, but has transferred to the third-party logistics to contract with the developers. The goal is to examine how the implementation of the external solution contract affects residential building and how an external third-party logistics solution works value creation for the building contractor. Method: For data collection observation and interviews have been used as methods of work. Findings: In order to create favourable condition for a builder and/or contractor in the implementation of a centrally decided external third party logistics solution requires: Early involvement of third-party logistics contractor in the planning stage with the motto "first and last on site" Clear and well-developed conditions for procurement of connectivity requirements, and the possibility of adaptation of the technical solution according to the customer identified needs. Open and continuous dialogue at all levels within the organizational structure. Implications: The complexity of how building projects should plan their logistics allows a handling of the issue at an early stage in the project is crucial. If the potential of the third party logistics for construction projects should be used needs to be early dialogue between the parties involved which the project's conditions have to control how the service should be designed. Limitations: The problem area and the number of actors involved in the external third-partylogistics make it difficult to pinpoint exact events that contributed to the situation has become in Vallastaden. The authors have not found the source of why it has been difficult to implement third-party logistics solution at an early stage in Vallastaden. What emerged during the process is that it needs to be sought answers higher up in the organizational structure of Vallastaden, but there is work boundaries made this a priority away and therefore not addressed in this report. Selected methods aimed solely at Skanska role in Vallastaden. Alternative viewpoints from different developers and construction contractors in Vallastaden has partly been highlighted in logistics meetings. It is important to point out that the work contains only a limited number of viewpoints on centrally approved third party logistics based on the many actors who are part of the project Vallastaden.Syfte: Extern logistiksamordning beslutades efter en utdragen upphandlingsprocess samtidigt som delar av projektet Vallastaden redan påbörjat byggnation. Det externa logistikföretaget dimensionerar och implementerar en helt fungerande lösning på kort tid. Kommunen har inte formellt anslutningskrav på byggherrarna utan har överlåtit till tredjepartslogistikern att ingå avtal med byggherrarna. Målet är att undersöka hur implementeringen av den externa tredjeparts-logistiklösningenpåverkar entreprenaden Bostadshuset samt hur en extern tredjeparts-logistiklösningarbetar värdeskapande för byggentreprenören. Metod: För datainsamling har observation samt intervju använts som metoder i arbetet. Resultat: För att skapa goda förutsättning för en byggherre och/eller byggentreprenör vid implementering av en centralt beslutat externt tredjepartslogistiklösning så krävs: Tidig involvering av tredjepartslogistikentreprenören i projekteringsskedet med mottot ”först och sist på plats vid produktion” Tydliga och väl utarbetade förutsättningar vid upphandling med anslutningskrav samt möjligheten till anpassning av den tekniska lösningen utefter kundens identifierade behov. Öppen och kontinuerlig dialog i alla led inom organisationsstrukturen. Konsekvenser: Komplexiteten kring hur byggprojekt ska planera sin logistik gör att en hantering av frågan i tidigt skede i projekten är avgörande. Om potentialen i tredjepartslogistik för byggprojekt ska nyttjas behöver dialog föras tidigt mellan de inblandade parterna där projektets förutsättningar måste styra hur tjänsten ska utformas. Begränsningar: Författarna har inte hittat källan till varför det har varit svårt att implementera tredjepartslogistiklösningen i ett tidigt skede i Vallastaden. Det som framkommit under arbetets gång är att det behöver sökas svar högre upp i organisationsstrukturen för Vallastaden, men där har arbetets avgränsningar gjort att detta prioriterats bort och behandlas därför inte i denna rapport. Valda metoder riktar sig enbart på Skanskas verksamhet inom Vallastaden. Alternativa synpunkter från olika byggherrar och byggentreprenörer inom Vallastaden har delvis uppmärksammats vid logistikmöten. Det är viktigt att poängtera att arbetet enbart innehåller ett begränsat antal synvinklar på centralt beslutad tredjepartslogistik utifrån de många aktörer som är en del av projektet Vallastaden.

Full textAbstract:
Many studies into construction procurement methods reveal evidence of a need to change the culture and attitude in the construction industry, transition from traditional adversarial relationships to cooperative and collaborative relationships. At the same time there is also increasing concern and discussion on alternative procurement methods, involving a movement away from traditional procurement systems. Relational contracting approaches, such as partnering and relationship management, are business strategies that align the objectives of clients, commercial participants and stakeholders. It provides a collaborative environment and a framework for all participants to adapt their behaviour to project objectives and allows for engagement of those subcontractors and suppliers down the supply chain. The efficacy of relationship management in the client and contractor groups is proven and well documented. However, the industry has a history of slow implementation of relational contracting down the supply chain. Furthermore, there exists little research on relationship management conducted in the supply chain context. This research aims to explore the association between relational contracting structures and processes and supply chain sustainability in the civil engineering construction industry. It endeavours to shed light on the practices and prerequisites for relationship management implementation success and for supply sustainability to develop. The research methodology is a triangulated approach based on Cheung.s (2006) earlier research where questionnaire survey, interviews and case studies were conducted. This new research includes a face-to-face questionnaire survey that was carried out with 100 professionals from 27 contracting organisations in Queensland from June 2008 to January 2009. A follow-up survey sub-questionnaire, further examining project participants. perspectives was sent to another group of professionals (as identified in the main questionnaire survey). Statistical analysis including multiple regression, correlation, principal component factor analysis and analysis of variance were used to identify the underlying dimensions and test the relationships among variables. Interviews and case studies were conducted to assist in providing a deeper understanding as well as explaining findings of the quantitative study. The qualitative approaches also gave the opportunity to critique and validate the research findings. This research presents the implementation of relationship management from the contractor.s perspective. Findings show that the adaption of relational contracting approach in the supply chain is found to be limited; contractors still prefer to keep the suppliers and subcontractors at arm.s length. This research shows that the degree of match and mismatch between organisational structuring and organisational process has an impact on staff.s commitment level and performance effectiveness. Key issues affecting performance effectiveness and relationship effectiveness include total influence between parties, access to information, personal acquaintance, communication process, risk identification, timely problem solving and commercial framework. Findings also indicate that alliance and Early Contractor Involvement (ECI) projects achieve higher performance effectiveness at both short-term and long-term levels compared to projects with either no or partial relationship management adopted.

The South African Construction Industry is one of the largest contributors to the gross domestic product of the country as well as to employment. It has, however, been experiencing significant challenges due to multifaceted factors. The main objective of this research was to identify the supply chain management constraints within the South African Construction Industry and how these can be overcome. This study is by nature descriptive and exploratory and contains qualitative elements. The problems were identified through a literature review, focused group discussions and interviews with major construction companies in South Africa.
The findings also indicate that the main supply chain management constraints are to a greater extent internal and typical of supply chain methodologies and approaches. These constraints are among others the lack of coordination, collaboration and commitment between suppliers and clients within the supply chain, poor leadership in key areas of systems, design problems (many changes and inconsistent information), deficient internal and external communication and information transfer, inadequate management within the supply chain, mainly poor planning and control just to mention a few.
A model based on supply chain system management as well as the Theory Of Constraints (TOC) has been developed that can be a useful tool to address the constraints in the construction sector. Originating from the study are applicable recommendations for the South African construction industry supply chains, covering key themes that have been articulated in the study, particularly benchmarking to the theory of constrains. Such recommendations include further research core components of supply chain such as, collaborations, logistics and how each of system components can be linked to performance of the supply chain management system.

Full textAbstract:
Two trends are currently driving the need for supply chain firms to form closely integrated relationships: collaboration and digitisation. One of the ways to achieve digitisation of supply chain operations is to implement Inter-Organisational Information Systems (IOIS) with selected supply chain partners for a much more efficient, streamlined and orchestrated supply chain operations. Whilst IOIS can be implemented to support various cross-functional business processes (ranging from operational information exchange to pursuing strategic initiatives such as sharing ideas, identifying new market opportunities, and pursing a continuous improvement approach), in the context of this thesis, the purpose of IOIS implementation is to facilitate the inter-firm procurement-related operations with downstream supply chain firms. The study undertaken in this research project was initiated in response to an industry requirement to investigate the implementation of IOIS against a backdrop of improved Supply Chain Management and integration practices by large contractor organisations. A case study research strategy was adopted to investigate the IOIS project related, IOIS (system) related issues encountered in ex-ante and ex-post implementation stages of the IOIS. The study concludes that it is the non-technical factors that are critical to the successful delivery of IOIS projects and provides a guideline on IOIS implementation by large contractor organisations. The findings of this research project have been published in a number of peer-reviewed papers.

Full textAbstract:
This work focuses on the need for new knowledge to allow hierarchical multi-project management to be conducted in the construction industry, which is characterised by high uncertainty, fragmentation, complex decisions, dynamic changes and long-distance communication. A dynamic integrated project management approach is required at strategic, tactical and operational levels in order to achieve adaptability. The work sees the multi-project planning and control problem in the context of supply chain management at main contractor companies. A portfolio manager must select and prioritise the projects, bid and negotiate with a wide range of clients, while project managers are dealing with subcontractors, suppliers, etc whose relationships and collaborations are critical to the optimisation of schedules in which time, cost and safety (etc) criteria must be achieved. Literature review and case studies were used to investigate existing approaches to hierarchical multi-project management, to identify the relationships and interactions between the parties concerned, and to investigate the possibilities for integration. A system framework was developed using a multi-agent-system architecture and utilising procedures adapted from literature to deal with short, medium and long-term planning. The framework is based on in-depth case study and integrates time-cost trade-off for project optimisation with multi-attribute utility theory to facilitate project scheduling, subcontractor selection and bid negotiation at the single project level. In addition, at the enterprise level, key performance indicator rule models are devised to align enterprise supply chain configuration (strategic decision) with bid selection and bid preparation/negotiation (tactical decision) and project supply chain selection (operational decision). Across the hierarchical framework the required quantitative and qualitative methods are integrated for project scheduling, risk assessment and subcontractor evaluation. Thus, experience sharing and knowledge management facilitate project planning across the scattered construction sites. The mathematical aspects were verified using real data from in-depth case study and a test case. The correctness, usefulness and applicability of the framework for users was assessed by creating a prototype Multi Agent System-Decision Support System (MAS-DSS) which was evaluated empirically with four case studies in national, international, large and small companies. The positive feedback from these cases indicates strong acceptance of the framework by experienced practitioners. It provides an original contribution to the literature on planning and supply chain management by integrating a practical solution for the dynamic and uncertain complex multi-project environment of the construction industry.

Full textAbstract:
The location of distribution centers is an important strategic decision in supply chain design, particularly as it relates to service quality, productivity, and profitability of the firm. There has been extensive research performed on distribution location models which require the use of complex algorithms and assumptions that make use of these models difficult in practice for small and medium enterprises (SMEs) that have limited capital and resources. Studies have also failed to capture and quantify potential business results of using more sophisticated methods. In this study, a deterministic and static location-allocation model is designed using a prototype software tool. The tool is a collection of Excel/VBA programs formulated as a mixed integer programming (MIP) model. Research was done in conjunction with a personal care products company that provided a unique opportunity to evaluate the manual methods typically used in SMEs with the results of the software tool and the potential business impact. Both quantitative data, including customer locations and order information, as well as qualitative data were collected from the company. A total of five models were simulated using the prototype software tool, including one model of the current supply chain for use as a base comparison, and four future-state models of potential distribution center (DC) location scenarios. The objective in each of these models was to minimize transportation costs while maintaining the desired service fulfillment levels. The use of the prototype software tool resulted in a more optimal supply chain solution. The optimized DC location resulted in a network design with a 6.5% reduction in transportation costs from the base model, and a 0.8% reduction in transportation costs from a location previously chosen by the company. The results also provided insight into considering weighted shipping volume in location analysis as it can serve as a magnifier of business impact and rapid diminishing returns when shipping product below an average of 10 pounds. The use of an optimization tool was shown to mitigate many issues SMEs encounter in attempting to synthesize multiple variables in the DC location problem.

Full textAbstract:
Byggbranschen karakteriseras av projektbaserade organisationer och temporära försörjningskedjor. Branschen är spridd på många aktörer och det ställer höga krav på kommunikationen mellan dem. Traditionellt sett har företagen arbetat självständigt utan koppling till de andra medlemmarna i försörjningskedjan men fördelarna med att samarbeta över de organisatoriska gränserna börjar bli allt tydligare. Förändringen grundar sig i att kunderna har mer inflytande på marknaden och det är därför viktigare för företagen att snabbt reagera på förändringar i trender och skapa kvalitativa produkter till låga kostnader. Att styra och leda flödet av material, information och pengar i försörjningskedjan från tillverkning till slutprodukt är därför vital för att behålla konkurrenskraften i organisationerna. Utvecklingen med digitaliseringen har lett till att kvalitativ data krävs för att utreda hur ny teknik kan implementeras i syfte att förbättra försörjningskedjans flöden. För att identifiera effekten av förändringar utförs därför en nulägeskartläggning av material- och informationsflödet för ett köks försörjningskedja. Studien visar hur flödet fungerar i nuläget och belyser processer som kan förbättras med hjälp av ny teknik. Utredningen är baserad på intervjuer och observationer från Marbodals fabrik till inbyggnadsplatsen för en köksleverans i ett NCC projekt. Insamlad data har därefter analyserats utifrån den initiala litteraturstudiens teorimodell och aktiviteterna i materialflödet. Köksleveransen valdes med avseende på att det är en vanligt förekommande leverans vid både ny- och ombyggnation. Den innehåller även en viss komplexitet, dels i tillverkningen men även i materialhanteringen. I studien identifierades slöserier i material- och informationsflödet. Dessa berör främst materialhanteringen på arbetsplatsen, samt intern- och externkommunikation i projektet. Utredningen visar att förbättringar i entreprenörens framtida inköp kan åstadkommas genom: Att säkerställa en gemensam målbild och syfte med arbetet för att reducera antalet missförstånd som sprids i organisationen och därefter vidare i försörjningskedjan. Involvera leverantörer och yrkesarbetare tidigt i planeringen. I planeringen av leveransen lägga vikt på att förstå leveransvillkoren och vilken flexibilitet som finns från leverantörens sida. I samband med leveransplaneringen ha en klar bild hur materialet paketeras och inspektera intransportvägen för att identifiera och förebygga hinder. Planera varje beställning så att inte material ligger i onödan på arbetsplatsen då det är kostsamt att flytta runt det. Informera involverade underentreprenörer (UE) vid förändringar i planeringen då det kan resultera i krockar.The construction industry is characterised by project based organisations and temporary supply chains. The fragmentation in this industry is tangible, placing significant communication pressure on supply chain members. Traditionally, companies have worked independently without ties to other members of the supply chain, but experience has shown increasing benefits of cooperation beyond company borders. This change of focus is due to the growing influence of customers, making it essential for suppliers to react to fluctuating changes in trends and produce quality products at low prices. Supply chain management methodshave because of this gained influence since they handle the flow of material, information and financial flow from manufacturing to end customer in order to stay competitive. The development of digitalisation is creating a need for qualitative data on which to base new research regarding how emerging technologies can be implemented to enhance the different flows in the supply chain. In order to measure changes made in the supply chain, the current state of mapping of a kitchens material and information flow can work as a reference and point out problems that could be solved with such technologies. This investigation is based on interviews and observations from the factory of the supplier to the assembly site for a kitchen delivery in an NCC project. Collected data has been analysed through the lens of theories found in the literature review and the material handling process. The kitchen delivery was selected because it’s a common delivery to new construction and renovation projects in the construction industry. Also there is a certain complexity regarding the manufacturing- and the material handling process. The study identified waste in the material and information flows. These concerns apply to material handling on the construction site and both internal and external communication within the project. The aforementioned findings led to the following improvement suggestions for future purchases of the contractor: Ensure that everyone involved in the project has the same view on the purpose and goal for the conducted work. This can reduce the number of potential misunderstandings passing on in the project and later the supply chain. Suppliers and workers should have connection to the purchasing processes during the early stages of planning. Confirm understanding of the terms of delivery and the flexibility of the suppliers. Perform inspection of the intended transport methods of materials ahead of delivery to solve problems related to internal transportation in advance. Plan the purchase in detail to make sure it fits the production phase. Inform involved subcontractors in the project of changes in planning to avoid collision or unnecessary wastes.

Full textAbstract:
En undermålig leveransprestation av maskiner och utrustning skapar problem i hela försörjningskedjan för ett byggprojekt. Ifall maskiner och utrustning inte levereras efter överenskommen tid, bidrar det till stillestånd och förseningar av byggprojektet. Bygget stannar upp om inte rätt maskiner, finns på rätt plats, i rätt skick och i rätt kvantitet. Syftet med studien är att identifiera vilka moment som tillsammans utgör orderprocessen i uthyrningsbranschen och vad som påverkar tillförlitligheten av leveranser för uthyrning av maskiner och utrustning till byggbranschen. En processkartläggning har identifierat fem moment i orderprocessen, kundkontakt, ordermottagning, orderhantering, leverans och returer. För att veta hur väl orderprocessen presterar behöver mätetal införas. Utan mätetal är det svårt att veta ifall maskiner och utrustning levereras efter vad som överenskommits med kund. Mätetal underlättar även för förbättringar i processer då det går att jämföra mot tidigare mätetal för att se ifall en förbättring har blivit en förbättring eller enbart en förändring. En kombination av mätetal på tillförlitlighet från Supply Chain Operations Reference Model samt tillämpningar och metoder från Supply Chain Management kan förbättra tillförlitligheten av leveranser i en försörjningskedja som förser byggbranschen med maskiner och utrustning.A poor delivery performance of machines and equipment creates problems throughout the supply chain for a construction project. If machines and equipment do not arrive in compliance with agreed upon time, it will cause downtime and delays at the construction site. The construction site will come to a standstill if not the right machines is at the right place, at the right time, in the right condition and in the right quantity. The purpose of the report is to identify which elements constitute the order process for rental of machines and equipment, as well as provide suggestions on how the elements can be improved to increase the reliability of deliveries to and from construction projects. With process mapping five elements of the order process have been identified, customer support, receiving of orders, processing of orders, deliveries and returns. To know the performance of the order fulfillment, measurements need to be introduced. Without metrics, it is difficult to know if machines and equipment arrive at the construction site correctly. Metrics also facilitate improvements in processes as it is possible to compare to previous measures to see if an improvement has been an improvement or just a change. If metrics on reliability from the Supply Chain Operations Reference Model is combined with practices and methods from Supply Chain Management the reliability of deliveries in the supply chain that supplies the construction industry with machines and equipment can be improved.

Full textAbstract:
Supply Chain Integration (SCI) has been found by previous research to be correlated withincreased business performance. However, the rate of implementation of the concept isdependent on the industry, implying that this is determined by industry-specific factors. Thepurpose of this study was therefore to investigate how the Swedish wooden house industryapproaches SCI, and thereby identify industry-specific factors that influence integration. Toaccomplish this, an exploratory multiple case study was conducted, in which Swedish woodenhouse manufacturers and associated actors were interviewed. The study confirmed that thewooden house industry is affected by factors limiting SCI implementation, and that companiesin the industry are not integrated to any significant degree. Further, two industry-specificfactors were discovered to be inhibiting integration. First, the degree of product customizationgranted to customers by house manufacturers determines how much control over procurementdecisions is retained, and thereby potential for integration with suppliers. Customer orientationwas found to inhibit SCI in the wooden house industry due to its effect on productcustomization, in spite of previous literature classifying it as a driver. Secondly, thefragmentation of the contractor market was found to force house manufacturers to deal with amultitude of small actors to perform the on-site construction function, limiting investments inrelationships for any one given actor. The study also found that levels of internal integrationwas generally not at a level at which the benefits of SCI can be fully realized.

Full textAbstract:
Purpose: This thesis’ purpose is to identify a CLSC model of flat glass, including actors,waste sources, and what can be done with recycled flat glass. In addition, this researchaims to propose a cost structure of a flat glass CLSC. Thus, this thesis’ research questions(RQ) are: RQ1: How can closed-loop supply chains (CLSC) for the purpose of flat glasslook like? RQ1.A: What actors are a part of a flat glass CLSC? RQ1.B: What are thewaste sources of flat glass in a flat glass CLSC? RQ1.C: What are the uses of flat glassas secondary material? RQ2: How can a cost structure for a closed-loop supply chain(CLSC) for the purpose of flat glass look like? Method: For this purpose of this thesis the researchers chose to employ a pragmatistresearch philosophy. The thesis is an exploratory qualitative study using an abductiveapproach. A case study strategy was used, and data was collected through semi-structuredinterviews and a literature review. Seven interviews were conducted with the six casecompanies. Findings: A flat glass CLSC consists of three phases: manufacture, use, and secondary(raw) material. The main actors are float glass manufacturer, flat glass processor/refiner,flat glass distributor, construction and demolition company, flat glass recycler, and freighthauler. Sub-actors of a flat glass CLSC are raw materials supplier, government, thirdparty contractors, container glass manufacturer, and glass wool manufacturer. Secondarymaterial occurs during flat glass manufacturing, distribution/transport, construction, anddemolition. It can be divided into three types, i.e., pure, high quality cut-offs,contaminated flat glass, and end-of-use flat glass. The possible uses of flat glass assecondary material are float glass, container glass, and glass wool manufacturing. Thecost structure for a flat glass CLSC divides cost elements into the three phases of a flatglass CLSC and six supply chain cost categories, which include manufacturing cost,distribution cost, warehousing cost, administration cost, capital cost, and installation cost. Theoretical Implications: This master’s thesis helps in adding to two research areas: flatglass and CLSC. By reviewing existing literature and conducting the case studies inChina, Germany, and Norway, the researchers can reflect the current practices of flat glassCLSCs in different countries, thereby adding to existing scientific research to close theresearch gap of flat glass CLSCs. Practical Implications: This master’s thesis contributes to practice by providing a flatglass CLSC model and cost structure which can be used as a starting point of developinga flat glass CLSC and its cost structure. In addition, this thesis is connected to anotherbigger research project in collaboration with the Linnaeus University and the city ofVäxjö, the findings from this thesis are beneficial for improving the situation of flat glassin Sweden. Societal Implications: By researching circularity in CDW, this master’s thesis helps notonly the city of Växjö but also other Swedish cities to improve the situation of flat glassand strive towards a full circular economy, further contributing to an increase insustainability in Sweden.

Full textAbstract:
The improvement of construction systems and management systems do not move together in construction industry, not using the effective management approaches decrease the productivity of the work. The firms both in national and international area in manufacturing industry use supply chain management to preserve their competitive force.
As material costs account for a high percentage of the overall cost, the success of a project is heavily dependent on material related factors and processes. In Turkey because of extensively using in-situ concrete in construction, the supply chain for reinforcement and concrete is very important. One of the components of concrete is &ldquore-bar&rdquo
and its supply chain, rbSC (rebar supply chain) was investigated within the scope of this research. In this study a framework was developed on the basis of the information from a literature survey and a field-test consisting of face-to-face interviews and questionnaire to determine the factors affecting the rbSC externally and those related to the supply chain participants. The developed rbSC performance framework was analyzed with Structural Equation Modeling rules. LISREL software was used, and the outputs of LISREL were evaluated by relationing with the information obtained from literature survey. The developed framework can be used to maximize both effectiveness of the rbSC process and efficiency of time and cost related issues in the rbSC. rbSC performance was associated with the project performance at the end of the study to reach a higher-level scale. The difference between the performance ratings obtained by self-assessment of a participant and those obtained through assessment done by the others was used to determine the affects of cultural issues on performance. Common reasons for the lower performance were analyzed due to cultural context and recommendations were set down for rbSC participants to solve the problems.

This thesis examined the delay causes of Malaysian public sector projects. Using a systematic approach, the researcher identified the main delay factors and categorised them into pathogens. The pathogens were matched with beneficial Supply Chain Management (SCM) tools and developed into a holistic SCM framework to facilitate improvements in Malaysian public sector projects. The researcher concluded that SCM is the potential saviour for the delay dilemma and that it is necessary for the Malaysian government to initiate the revolutionary practice.

Full textAbstract:
Byggbranschen är en viktig näringsgren med stor direkt och indirekt påverkan på tillväxten och problem inom byggsektorn riskerar därför att fortplanta sig som negativa effekter på samhällsekonomin. Sedan länge brottas byggsektorn med en mycket svag produktivitetsutveckling. En direkt delorsak till detta är att en stor andel av arbetstiden på en byggarbetsplats läggs på annat än direkt värdeskapande arbete, såsom att vänta på eller att leta efter material. Detta beror i sin tur delvis på att leveransprecisionen är låg och logistiken är eftersatt inom byggbranschen. Därmed ligger det inom räckhåll att förbättra produktiviteten med bättre rutiner kring materialförsörjning och logistik. Denna studie har fokuserat på hur resursutnyttjandet i byggbranschen skulle kunna öka med hjälp av strukturerade arbetssätt inom bygglogistik och anlitande av tredjepartslogistiker. Specifikt har studien analyserat det logistikupplägg med en tredjepartslogistiker som använts vid den omfattande ombyggnation av Universitetssjukhuset i Linköping (US), som benämns Framtidens US (FUS). FUS omfattar ny- och ombyggnation i direkt anslutning till pågående sjukvårdsverksamhet och akuta vårdflöden får inte hindras. För att störa vården minimalt anlitades tredjepartslogistikern Bygglogistik för att samordna alla materialtransporter. Den föreliggande studien samlar upp de lärdomar som drogs av logistikupplägget under projektets första etapp (FUS1), analyserar hur dessa lärdomar omsattes under planeringen inför den andra etappen (FUS2) samt studerar följsamhet till de uppsatta logistikriktlinjerna och attityder till upplägget i såväl FUS1 som FUS2. Resultaten visar att logistikupplägget bidragit med stora värden i och med att inga akuta ambulanstransporter hindrats, mer tid har kunnat läggas på direkt byggande och projekten har fått bättre ekonomi. Men resultaten visar också att implementeringen inte varit smärtfri och att somliga fortfarande är skeptiska till värdet av upplägget. Dessutom finns en diskrepans mellan den operativa logistiktjänst byggherren upplever sig ha fått levererad och den mer utvecklande kunskapstjänst som byggherren trodde sig ha upphandlat.

The purpose of this thesis is to point out how a company can gain a better process by using PM in an effective way. The report concludes that the existence in practice of theoretically important aspects are different, also that the most correct way of leading the aspects are through the creation of a PM process. During this thesis work the benefits with performance measurements have been analyzed. Since the genesis of the industrialisation there have been growing needs to identify ways of understanding how a company functions. One of the main events historically leading to the broad adoption of PM was the introduction of the DuPont model. The DuPont model developed by DuPont and General Motors during the beginning of the 20th century quickly became the industry standard in the US for financial analysis. The Dupont model gave PM a central role in evaluating the performance of a company. Companies are today driven towards a higher level of responsiveness and flexibility in order to remain competitive. In order to measure the advancement towards these objectives, an increasingly complex set of activities collection of PM to monitor performance satisfactorily. Often however, PM are still developed around traditional, functional metrics focusing on departmental issues, rather than on the whole value stream. There has also been analyzed how a manufacturing company can use PM in an effective way. Under this thesis it emerged that the most crucial factor affecting the companies PM was that it was hard to understand how to use it correctly. When a company use it correctly it determines where the company stands, if they want to be competitive in the future and a method to maintain a good value stream flow. The economical factors for the company are at least important because all decisions always include costly investments. At the same time a company’s PM must be as efficient as possible and generate a good investment. Also other factors have been presented in this thesis but do not affect the effectiveness of the PM. The most important factors found to a more effective PM were; does the PM fulfil its purpose, is the performance attained, to make the purpose explicit and at last boost the education around the subject. The whole research has been carried out over a twenty-week period, during that period data collection has been performed via case studies. The rest of the data collection has been collected through a literature review by examining relevant data to answer the two research questions. This thesis have led to a better understanding regarding how to use PM and the benefits of it. This are based on the collected data from the case studies and from the theoretical findings, the empirical data were analyzed in a way that the company understood what was wrong with today´s PM.

Målet med denna studie är att hjälpa fallföretaget med att minska materialhanteringen på avdelningen internlogistik, som bland annat innefattar godsmottagning och lagerhantering. Detta kommer att göras genom framtagning av en ny anläggningslayout. Genom automatisering av utlastningen och den nya layouten reduceras och/eller elimineras slöserier i form av transport, tid, etc. samtidigt som ett effektivare flöde skapas internt på företaget. För att kunna genomföra denna studien har kvalitativa och kvantitativa metoder använts vid datainsamlingen för att säkerställa att studien erhåller en hög vetenskaplig trovärdighet. Bakgrunden till att studien genomfördes är för att det blivit en svårighet för växande industriföretag att kunna hantera materialhanteringen på grund av för mycket arbete och kunna ha en effektiv internlogistik. Detta i sin tur ligger i grund för företag att kunna uppnå hög utnyttjandegrad, effektivt flöde och en välplanerad internlogistik för att kunna bli starkare gentemot konkurrenterna.

Full textAbstract:
Syfte: I problembeskrivningen konstaterades att de logistikproblem som upplevs på byggprojekt ofta är kopplade till glappet mellan projekterings- och produktionsfasen. Problemen är även kopplade till brist på informationsutbyte, projektförståelse och långvariga relationer samt attityd till samarbeten och skilda tolkningar. Syftet är att undersöka hur informations- och materialflödena hanteras på anläggningsprojekt samt vad som kan göras för att optimera försörjningskedjan och därmed främja logistiken. Metod: Undersökningens huvudsakliga angreppssätt är en kvalitativ studie. Kvalitativa data, i form av primärdata, samlas in genom en intervjustudie. För att få en teoretisk bakgrundsförståelse samlas sekundärdata in genom att studera tidigare litteratur inom ämnet. Detta ligger till grund för att uppnå det formulerade målet för undersökningen. Resultat: Studien konstaterar att ett gränsöverskridande samarbete och ett helhetsperspektiv behövs för att gynna försörjningskedjan och logistikarbetet på ett anläggningsprojekt. Om aktörer i de olika faserna involveras i varandras arbete skapas bättre förutsättningar för att hantera informations- och materialflödena och därmed främja logistiken på projektet. Resultatet bidrar till ökad inblick i hur flödena hanteras idag samt vilka begränsningar och förbättringsmöjligheter som finns. Detta ger en indikation på varför anläggningsbranschen inte har nått samma framgångar kring förbättring av försörjningskedjan som andra företag. Konsekvenser: För att möta den utmaning som finns i anläggningsbranschen med avseende på logistiken krävs följande: Att informations- och materialflödet hanteras på ett strukturerat sätt. Att skapa långvariga relationer, använda digitala verktyg i större omfattning och att entreprenörerna gör integrerade inköp. Att aktörer inom de olika faserna integreras i varandras arbete, ha en samordningsansvarig inom projektet och använda sig utav logistikcentra. Begränsningar: Studien avgränsades till att fokusera på aktörer som i regel inte har en direkt inverkan på logistikarbetet. I efterhand görs bedömningen att det varit till rapportens fördel att intervjua fler aktörer som kan påverka logistiken. Detta för att få en bredare bild av den syn som finns i projekterings- och planeringsfasen samt byggfasen. Trots att studien visar på olika aktörers perspektiv av situationen uppnås inte en rättvis bild och ett mer balanserat urval av respondenter hade behövts. Det är viktigt att nämna att studien inte fokuserar på att undersöka hur förbättringarna kan genomföras. Nyckelord: Logistik, Supply Chain Management, ramverk för Supply Chain Planning, anläggningsprojekt, informations- och materialflöden.Purpose: In the introduction it was concluded that the experienced logistical difficulties on a construction site often were related to multiple reasons. Examples of these are the disconnection between the design and production phase, lack of information exchange, project understanding and relationships as well as attitude towards cooperation and the various interpretations. The aim of this study is to investigate how information and material flows are managed within construction projects as well as finding options to optimize the supply chain and in turn promote the logistics. Method: For the methodological approach of the study, a qualitative method is used. Qualitative data, in form of primary data, is collected through an interview study. To build an understanding of the theoretical background, secondary data is gathered by studying former literature research findings. This is the basis for achieving the goal of the study. Findings: The result of the study shows that a cooperation between disciplines and a holistic approach is needed to promote the supply chain and logistics within a construction project. When disciplines in the various phases are involved in each other’s work, conditions are being created for managing the information and material flows and in turn improving the logistics. The result contributes to insight as to how the flows are managed today as well as the experienced limitations and improvements. This gives an indication of why the construction industry has not achieved the same success in enhancement of the supply chain as other industries. Implications: This is what is needed to meet the challenge of improving the logistics in the construction industry: Information and material flows need to be handled in a structured manner. Creation of long-term relationships, increased usage of IT-tools and integrating purchases within contractors. Disciplines within the various phases need to be integrated in each other’s work, having someone who coordinates the responsibilities within the project and utilization of logistics centers. Limitations: Initially, the study was limited to only focusing on disciplines who generally do not have a direct impact on the logistics. In hindsight, it is considered that the study would benefit from interviewing more disciplines who can affect the logistics. This would provide a broader view of the aforementioned phases’ perspective. Although the study indicates different disciplines’ standpoint of the situation, a fair result is not fulfilled as a more equal selection of interviewees would be needed. It is important to note that the study does not focus on investigating how the improvements can be implemented. Keywords: Logistics, Supply Chain Management, framework for Supply Chain Planning, construction projects, information and material flow.

Full textAbstract:
The manufacturing industry has made an extensive journey through the last century when it comes to increasing productivity. Results in the construction industry end up far behind manufacturing and do not show anywhere near the same efficiency increase, improved quality or decreased costs. There are a lot of potential savings in the form of activities that consumes resources without creating value for the end customer, also called waste. Waste in combination with uncertainty and variability in task duration forces the project duration to be longer than necessary. The purpose of this study is to investigate the opportunity to shorten the lead time of a construction project and investigate how construction companies can work continuously towards shorter project lead times. The purpose has been fulfilled through a time study performed at four projects managed by one of the leading construction developers of residential buildings in Scandinavia. Waste and variability were mapped in the interior phase. The measured time for each activity was categorized either as; value adding time (VT), necessary but non-value adding time (NNVT) and non-value adding time (NVT). The results showed that mounting consists of 48 % VT, 28 % NNVT and 24 % NVT, while material handling consists of 0 % VT, 75 % NNVT and 25 % NVT. The results further showed large variability in task duration between the projects. Theory from lean, logistics and scheduling were combined to form three different scenarios for shortening project lead times. The first scenario describes how to work with removing waste from the process. The second scenario describes how to reduce variability and thus be able to reduce buffers in the time plan. The last scenario describes how support processes, for example material handling, can be removed from the critical path, in order to reduce project lead times. A proposal for a general approach for continuously working with decreasing project lead times is also presented. Central aspects for shortening project lead times were concluded to be the takt time, variability and risk. The proposed approach involves a combination of the three scenarios, where their impact on each other is considered.Tillverkningsindustrin har gjort en omfattande resa under det senaste århundradet när det gäller att öka produktiviteten, medan byggbranschen inte visar i närheten av samma ökning i effektivitet, förbättrad kvalitet eller minskade kostnader. Det finns många potentiella besparingar i form av aktiviteter som förbrukar resurser men som inte skapar något värde för kunden, även kallat slöserier. Slöserier i kombination med osäkerhet och variabilitet i arbetsmomentens varaktighet tvingar projektens ledtider att vara längre än nödvändigt. Syftet med denna studie är att undersöka möjligheten att förkorta byggprojekts ledtider och undersöka hur byggföretag kontinuerligt kan arbeta mot kortare ledtider. Syftet har uppfyllts med hjälp av en tidsstudie utförd på fyra projekt vid en av de ledande projektutvecklarna av bostadshus i Skandinavien. Slöserier och variabilitet i inredningsskedet har kartlagts. Den uppmätta tiden för varje aktivitet är kategoriserad efter; värdeskapande tid (VT), nödvändig men icke-värdeskapande tid (NIVT) och icke-värdeskapande tid (IVT). Resultaten visar att montering består av 48 % VT, 28 % NIVT och 24 % IVT, medan material hantering består av 0 % VT, 75 % NIVT och 25 % IVT. Vidare visar resultaten på stor variabilitet i varaktigheten av aktiviteter mellan projekten. Teori från lean, logistik och schemaläggning kombinerades för att bilda tre olika scenarier som kan användas för att förkorta projektens ledtider. Det första scenariot beskriver hur man kan arbeta med att eliminera slöserier från processen. Det andra beskriver hur man kan minska variabiliteten och därmed kunna minska buffertarna i tidplanen. Det sista scenariot beskriver hur stödprocesser, som t.ex. materialhantering, kan brytas ut från den kritiska linjen, i syfte att minska projektets ledtid. Ettförslag till ett generellt sätt att kontinuerligt arbeta med att minska projektens ledtider är ocksåframtaget och innehåller en kombination av de tre scenarierna. Det framkommer att centrala aspekterför att förkorta projektens ledtider är takttid, variabilitet och risk. Det föreslagna arbetssättetinnefattar en kombination av de tre scenarierna, där hänsyn tagits till deras inverkan på varandra.

Full textAbstract:
I examensarbetet utförs en totalkostnadsanalys av tre olika transportalternativ av gipsskivor till kontorsbyggen i citymiljö åt Skanska. I det ena alternativet levereras gipsskivorna direkt från fabrik till byggarbetsplats. I det andra alternativet köps gipsskivorna in från en grossist och i det tredje alternativet går gipsskivorna via en terminal hos en tredjepartslogistiker. Slutsatserna som tagits fram visar på att ett lågt inköpspris kan medföra öka kostnader längre fram i kedjan i form av sämre kvalité och längre väntetider för personalen.

Full textAbstract:
Problem: Byggbranschen är en av de större industrisektorerna som lyckas skapa minst integration. Branschens projektbaserade karaktär och höga fragmentering utgör en betydande utmaning för att involvera berörda parter. Forskarna i denna studie anser det finnas en brist i hur organisationer inom byggbranschen går tillväga för att integrera sina underentreprenörer. Syfte: Studiens syfte har varit att skapa förståelse för de behov och implikationer outsourcing medför i praktiken samt hur dessa optimeras för att nyttja outsourcingens fulla potential. Genom att undersöka en stor aktörs tillvägagångssätt att integrera sina underentreprenörer i en projektbaserad bransch ämnar studien bidra med ökad kunskap för hur integrering kan ske när en organisation väljer att outsourca delar av sin verksamhet. Metod: Studien har använt sig utav semistrukturerade intervjuer samt en av studiens forskares utförda observation som en del av det empiriska underlaget. Intervjuerna skedde med tre av Skanskas anställda: inköpsansvarige, logistikansvarige samt blockchef för SN81. Sedan genomfördes intervjuer med två underentreprenörer och en andraleds-underentreprenör: VSM, Bellmans och Olderin. Slutsats: Integration sker genom kontrakt, strategiska samarbeten och genom informationsdelning. Genom kontraktering och avtal med specifika krav försöker Skanska upprätthålla de standarder och tillvägagångssätt som de anser vara betydande. Som resultat av de strategiska samarbeten och långsiktiga relationer Skanska har skapas ett beroendeförhållande till UE. Outsourcing av verksamhetsområden bidrar till minskad kunskap, insyn och kontroll av verksamheten. Till följd av att Skanska skapar självständiga arbeten och förstärker relationen mellan enheter minskas osäkerheten. Med hjälp av kontrollverktyg minskar Skanska risken för opportunistiskt beteende hos UE.Problem: The construction industry is one of the major industrial sectors that has created the least integration. The industry's project-based character and high fragmentation contributes to a significant challenge for involving stakeholders. The researchers in this study believe there is a shortage in literature of how organizations in the construction industry manages to integrate their subcontractors. Purpose: The purpose of the study has been to create a clear understanding of the needs and implications of outsourcing in practice and how these are optimized to utilize the full potential of outsourcing. By studying a major actor's approach to integrate its subcontractors in a projectbased industry, the study aims to provide increased knowledge of how integration can be successful when an organization chooses to outsource parts of its production. Method: This study has used semi-structured interviews and one of the researcher’s observations as part of the empirical basis. The interviews took place with three of Skanska's employees: purchasing manager, logistics manager and block manager for SN81. Following interviews were conducted with two subcontractors and one sub-subcontractor: VSM, Bellmans and Olderin. Conclusion: Integration takes place through contracts, strategic partnerships and information sharing. Through contracting and agreements with specific requirements, Skanska tries to maintain the standards and approaches that they consider to be significant. As a result of the strategic partnerships and long-term relationships Skanska has created an interdependence to the subcontractors. Outsourcing of business areas contributes to reduced knowledge, insight and control of operations. As a result of Skanska's creation of self-contained tasks and creation of lateral relations, uncertainty is reduced. With the help of control tools, Skanska reduces the risk of opportunistic behaviour among subcontractors.

Full textAbstract:
The construction industry is the largest industry in the world and operates in knowledge-based project organisations. The success of projects relies on the management of both tacit and explicit knowledge. This situation calls for a method for disseminating tacit knowledge from individuals to achieve higher performance and success value in construction projects. For the purpose, this study first articulates the problems of knowledge management in the construction industry. Then, by reviewing some knowledge engineering and management literatures, this research sets a theoretical foundation of knowledge management in the construction industry. A questionnaire survey was used to investigate and examine the current situation of knowledge management in UK and China construction industry. The result of frequency analysis and nonparametric test analysis provides the perceptions on the importance of knowledge transfer, the implementation of knowledge transfer, the resources of knowledge, and barriers for tacit knowledge transfer. From the literature review, this study proposes a tacit knowledge transfer process framework (3I) and identifies a series of factors correlated with effectiveness of knowledge transfer. This thesis also identifies four main independent variables - organsiational culture, organizational structure, IT technology and No-IT technology, and investigates the relationship between organisational elements with these factors and the performance of knowledge transfer. The findings are based on three case studies and responses of questionnaire survey and interviews. The results reveal that there are significant relationships between some of the variables and either the creation of knowledge assets or performance of knowledge transfer. Therefore, it is necessary for construction organsiations to consider these elements in developing and implementing a knowledge management strategy/system in a construction organisation. This study proposes a practical methodology to transfer knowledge by using an integrated system (TKTMS). The TKTMS can be an effective tool for all project members to transfer tacit knowledge across firms' boundaries and accelerate the speed of knowledge creation, share and transfer in the construction industry. The integration of the function model (IDEF0) with the information model (IDEF1) is applied to understand the necessary function/information for consideration in the 3I model and implement TKTMS.

Full textAbstract:
Den globala temperaturen fortsätter att stiga till följd av koldioxidutsläpp. Globalt orsakar bygg- och anläggningssektorn en fjärdedel av dessa utsläpp. Green Supply Chain Management (GSCM) är ett koncept som beskrivs ha potential att minska sektorns miljöpåverkan och därigenom bidra till hållbar utveckling. Hela försörjningskedja är av betydelse för att reducera utsläpp orsakade av sektorn och samtidigt bemöta samhällets ökade tryck kring hållbarhet samt Agenda 2030, Parisavtalet och Fossilfritt Sveriges uppsatta klimatmål. Samarbete i försörjningskedjan beskrivs kunna påskynda utveckling för reducering av klimatpåverkan och konceptet GSCM erbjuder metoder för sådana samarbeten. Målet med studien är att undersöka en inköpsverksamhet tillhörande bygg- och anläggningssektorn, verksamhetens samverkan kring hållbarhet och miljö med interna parter samt med leverantörer för att utreda applicering av GSCM i klimatarbetet. Studien syftar till att bidra med förståelse kring GSCM-aktiviteter och nyttjande av dessa i bygg- och anläggningssektorns inköpsverksamheter samt att identifiera utmaningar för hållbar utveckling. För att göra detta har en kvalitativ fallstudie genomförts, där ett fall studerats. Data samlades huvudsakligen in genom semistrukturerade intervjuer med personer från en inköpsavdelning tillhörande ett företag inom bygg- och anläggningssektorn. Perspektiv från några av inköpsavdelningens leverantörer samt från företagets hållbarhetsavdelning inkluderades också. Resultatet indikerar att förståelse, tydlig ansvarsfördelning samt konkreta mål är betydelsefullt för applicering av GSCM-aktiviteter i inköpsverksamheter inom bygg- och anläggningssektorn. Kopplat till klimat- och hållbarhetsarbetet har internorganisatoriska utmaningar, externa nätverksutmaningar, nätverksutmaningar, finansiella utmaningar, tekniska utmaningar samt reglerande utmaningar identifierats. Studien bidrar med insikt om hur applicering av GSCM-aktiviteter kan stödja reducering av bygg- och anläggningssektorns klimatpåverkan samt om utmaningar för hållbar utveckling inom sektorn. Några av studiens begränsningar kan härröra från metodiken av en kvalitativ fallstudie samt från GSCM-konceptets otydliga definition. Fortsatt forskning kan förslagsvis studera vilka GSCM-aktiviteter som kan generera störst positiva effekter på organisationers klimatarbete.Global warming continues due to increased emissions of carbon dioxide. Globally, the construction sector causes a quarter of these emissions. Green Supply Chain Management (GSCM) is a concept with potential to reduce the environmental impact from the sector and in turn contribute to sustainable development. All parts of the sector are of importance to reduce the emissions caused by the sector, as well as consider the increased pressure from society, Agenda 2030, the Paris Agreement and the goals of Fossil Free Sweden. Cooperation in the supply chain is described as having the ability to accelerate progress to reduce climate impact, and the GSCM concept offers methods for such collaborations. The aim of this study is to investigate a purchasing department in the construction sector and its collaboration regarding environmental sustainability with internal parties and suppliers to examine the application of GSCM in climate work. The purpose is to contribute with knowledge about GSCM activities, their application in purchasing departments in the construction sector, and to identify challenges for sustainable development. A qualitative single-case study was performed. Data were mainly collected through semi-structured interviews with people from one purchasing department at an organization within the construction sector. The perspective of the suppliers and the sustainability department within the organization was also included. The findings indicate that understanding, clearly allocated responsibility, and tangible goals are relevant factors when purchasing departments within the construction sector applicate GSCM activities. Identified challenges to the climate and sustainability work were related to internal networks, external collaborations, economy, technique, and regulations. This study contributes with knowledge about GSCM activities and how the application supports the reduction of climate impact from the construction sector. As well, the study gives insight into the challenges for sustainable development in the sector. Some of the limitations of this study may occur due to the methodology of a qualitative case study and from the ambiguity of the GSCM concept. Future research could study which GSCM-activities having the greatest positive effects on organizations' climate work.

Full textAbstract:
Logistics and supply chain in the Architecture, Engineering and Construction (AEC) industry can be seen as coordinated collaboration that is subject to managerial risks. The managerial risks are mitigated by Building Information Modelling (BIM) and Geo-Information Science (GIS), which are two distinctive digital transformative tools which are revolutionizing and accelerating the AEC industry in recent years. Many gains have been achieved concerning the capacity of BIM and GIS to enable collaborative workflows that minimize data loss and reduce inefficiencies in construction. In the past decade, most scholarly literature on BIM and GIS integration for supply chain management have focused on coordination and visualization to improve supply chain operational efficiency. While BIM optimizes visualization and manages the data related to specific projects, GIS coordinates and manages the data related to the outside environment of the project. An integrated BIM-GIS adoption for Construction Supply Chain Management (CSCM) offers value propositions for client and contracting organizations as information/data is seamlessly shared among them to guide decision making at every phase of the construction project. However, no detailed study has been conducted so far on assessments of the value creation 4D BIM-GIS brings to the AEC industry when espoused for CSCM. To fill this gap, this paper aims to identify and prioritize the value propositions to 4D BIM-GIS adoption for CSCM in the Swedish AEC industry. Based on the reflective perceptions and evaluations of the AEC industry, the paper demonstrated the varied opinions from current active users and those who are yet to adopt 4D BIM-GIS for CSCM. ‘Time savings, ‘Increased efficiency and productivity and ‘Improved communication and information sharing’ were ranked as topmost drivers for 4D BIM-GIS adoption. The paper recommends corporate level training as pivotal in familiarizing workers with the new techniques that combine BIM and GIS in AEC practice.Logistik och försörjningskedjan inom arkitektur, teknik och konstruktion (ABE) kan ses som ett samordnat samarbete med överhängande ledningsrisker. Riskerna som hanteras kan mildras av Byggnadsinformationsmodellering (BIM) och Geografiskt informationssystem (GIS), som är två digitalt distinkta transformativa verktyg som revolutionerat och påskyndat ABE-sektorn de senaste åren. Många vinster har uppnåtts med avseende på kapaciteten av BIM och GIS, vilket har möjliggjort ett samarbetsflöde som minimerat dataförlust och minskat ineffektiviteten i byggandet. Under det senaste decenniet har den mest vetenskapliga litteraturen om BIM- och GIS-integration för ledning av försörjningskedjan fokuserat på samordning och visualisering för att förbättra effektiviteten i försörjningskedjan. BIM optimerar visualisering och hantering av data, relaterat till specifika projekt, medan GIS samordnar och hanterar data relaterat till projektets omgivning. En integrerad BIM-GIS-antagande för konstruktionsledningen av försörjningskedjan (CSCM) erbjuder värdeförslag för klient- och beställarorganisationer, eftersom information / data sömlöst delas mellan dem för att kunna guida beslutsfattandet i varje fas av byggprojektet. Emellertid har ingen detaljerad studie hittills genomförts om bedömningar av värdeskapandet som 4D BIM-GIS ger till ABE-sektorn när de används för CSCM. För att fylla denna kunskapslucka syftar denna studie till att identifiera och prioritera värdeförslag till 4D BIM-GIS-antagande för CSCM i den svenska ABE-sektorn. Baserat på de reflekterande uppfattningarna och utvärderingarna från ABE-sektorn, visar studien de olika åsikterna från de nuvarande aktiva användare och de som ännu inte har antagit 4D BIM-GIS för CSCM. ”Tidsbesparingar,” Ökad effektivitet och produktivitet” och ”Förbättrad kommunikation och informationsdelning” rankades som de främsta drivkrafterna för 4D BIM-GIS-antagande. Studien rekommenderar utbildning på företagsnivå som en central faktor för att bekanta sig med de nya teknikerna som kombinerar BIM och GIS i ABE-sektorn.
