Abstract:
The main concern of a construction client is to procure a facility that is able to meet its functional requirements, of the required quality, and delivered within an acceptable budget and timeframe. The cost aspect of these key performance indicators usually ranks highest. In spite of the importance of cost estimation, it is undeniably neither simple nor straightforward because of the lack of information in the early stages of the project. Construction projects therefore have routinely overrun their estimates. Cost overrun has been attributed to a number of sources including technical error in design, managerial incompetence, risk and uncertainty, suspicions of foul play and even corruption. Furthermore, even though it is accepted that factors such as tendering method, location of project, procurement method or size of project have an effect on likely final cost of a project, it is difficult to establish their measured financial impact. Estimators thus have to rely largely on experience and intuition when preparing initial estimates, often neglecting most of these factors in the final cost build-up. The decision-to-build for most projects is therefore largely based on unrealistic estimates that would inevitably be exceeded. The main aim of this research is to re-examine the sources of cost overrun on construction projects and to develop final cost estimation models that could help in reaching more reliable final cost estimates at the tendering stage of the project. The research identified two predominant schools of thought on the sources of overruns – referred to here as the PsychoStrategists and Evolution Theorists. Another finding was that there is no unanimity on the reference point from which cost performance could be assessed, leading to a large disparity in the size of overruns reported. Another misunderstanding relates to the term “cost overrun” itself. The experimental part of the research, conducted in collaboration with two industry partners, used a combination of non-parametric bootstrapping and ensemble modelling with artificial neural networks to develop final project cost models based on about 1,600 water infrastructure projects. 92% of the validation predictions were within ±10% of the actual final cost of the project. The models will be particularly useful at the pre-contract stage as they will provide a benchmark for evaluating submitted tenders and also allow the quick generation of various alternative solutions for a construction project using what-if scenarios. The original contribution of the study is a fresh thinking of construction “cost overruns”, now proposed to be more appropriately known as “cost growth” based on a synthesises of the two schools of thought into a conceptual model. The second contribution is the development of novel models of construction cost estimation utilising artificial neural networks coupled with bootstrapping and ensemble modelling.

Abstract:
Accurate client budget estimates are critical to the initial decision-to-build process for the highway construction projects. This decision-to-build point in a project's development is seen as the international standard for measuring any subsequent cost estimate inaccuracies involved (National Audit Office/Department of Transport, 1992; World Bank, 1994; Nijkamp and Ubbels, 1999), with accuracy being defined as the difference between the initial project estimate at the decision-to-build stage and the real, accounted project cost determined at the time of project completion. Expressed as a percentage of estimated cost, this is often termed cost escalation, cost overrun or cost growth, and occurs as a result of many factors, some of which are related to each other, but all are associated with forms of risks. The analysis of these risks is often a necessary step for the improvement of any given estimating system and can be used to diagnose trouble spots and to pinpoint areas where project estimating accuracy improvement might be obtained. In this research, highway projects in Queensland, Australia that have suffered significant cost overrun are analysed. The research seeks to address the gap in the knowledgebase as to why highway projects overrun their costs. It focuses on understanding how client projects budgets go wrong, when dealing with project risk. The foundation for this research is drawn from the post-mortem analysis of highway projects, each costing in excess of A$1m and whose final total expenditure exceeded budget by 10% or greater. The research identifies client risk variables which have contributed to significant cost overrun and then uses factor analysis and also expert elicitation, using nominal group technique, to establish groups of importance ranked client risks. Stepwise multivariate regression analysis is then used to investigate any correlation of these risks, along with project attributes such as highway project type, indexed project cost, geographic location and project delivery method to the percentage of cost overrun. The research results indicates a correlation between the reciprocal of project budget size and percentage cost overrun that can be useful in clients determining more realistic decision-to build highway budget estimates when taking into account project size in relation to economy of scale.

Abstract:
In the global construction market, most construction companies are willing to undertake international projects in order to maximise their profitability by taking advantage of attractive emerging markets and minimise dependence on unfavorable domestic market conditions. In order to be awarded a contract in highly competitive global construction market, companies should excel in choosing the most attractive markets and prepare winning bids for the selected construction projects in those markets. While preparing bids, the major concern of companies is to offer an optimum price that will enable them to earn enough profits and win the contract at the same time, where profit making ability is strongly correlated with proper estimation of a risk premium that is added onto the estimated cost of the project. Due to the nature of construction works, there are lots of uncertainties associated with the project, market and country conditions. Therefore, how the profitability of the project changes with occurrence of various risk events, in other words, the sensitivity of project costs to risk events, should be estimated by bidders realistically. In this study, fuzzy set theory is used to estimate cost overrun risk in international projects at the bidding stage. The objective is to propose a methodology which can be used by bidders to quantify cost overrun risk so that a realistic risk premium may be determined. A fuzzy risk rating approach is proposed to quantify cost overrun risk rating, which takes into account of risks characterised in international construction projects. For this purpose, risk sources have been identified and a risk model is put forward by using influence diagramming method. Based on this risk model, a fuzzy risk rating algorithm has been defined and software has been developed to conduct fuzzy risk rating calculations easily. After a decision-maker inserts the necessary inputs related with project and country risk factors, the output of the software is a rating that takes into account of all factors that may affect cost overrun risk in international construction projects. The reliability of the algorithm and developed software have been tested by an application on a real construction project. The proposed methodology and decision support tool have been proved to be reliable for the estimation of cost overrun risk while giving bidding decisions in international markets.

Abstract:
Project cost increase is the main concern in international construction projects which usually results in disputes and conflicts among the project participants. The aim of this thesis is to construct a database that represents risk event history regarding international construction projects and construct a cost overrun prediction model. It is hypothesized that magnitudes of project related, company related and country related risk factors can be predicted by assessing the level of vulnerability by analogical reasoning with previous projects. The vulnerability and risk factors can further be used to predict cost overrun in the bid preparation stage of international construction projects. Thus, prediction models that link vulnerability with risk factors and cost are constructed by using a dataset of 166 international construction projects, which consists of 66 real and 100 hypothetical cases. Case-based reasoning (CBR) technique is used to construct the prediction models. After testing the performance of various CBR models using different weight generation and retrieval methods, error rate of +/- 7.15 % cost increase is achieved. The utilization of CBR models in the prediction of potential risk sources and cost overrun is demonstrated by a real case study. Finally, the benefits and pitfalls of using analogical reasoning for risk and cost overrun assessment of construction projects are discussed.

Abstract:
Cost overrun is prevalent in the construction industry. Usually, an owner sets a budget at the preliminary phase of a project which changes over time. Past studies are focused on analyzing the cost growth of design-bid-build projects during construction. Limited efforts have been made to analyze details of projects delivered with the Construction Manager General Contractor (CM/GC) method. This study tracks and analyzes the construction cost variation of a project from the conceptual phase to the design completion phase. The analysis is presented with a case study of a new stadium construction project. It identifies that the changes in the scope and design of the project due to the change in available budget were a major reason for variation in the cost estimates over time. Further, this study identifies a) trades with the highest variation in subcontractors’ bids, b) trades that were most overestimated, and c) trades that were most underestimated. The findings of this study is expected to aid owners, designers, and contractors of future projects in improving the preparation, planning, and estimating of future projects; reducing cost variation within trades; and optimizing the amount of contingency required to ensure the successful completion of similar projects.

Abstract:
Construction managers confront many problems. Still, this industry plays a vital role in the healthy growth of the economy of many countries throughout the developed and developing world. Effective management of construction projects has been a major research subject in the last century due to the importance of this industry and the amount of money it attracts. One critical problem facing construction managers is inefficient cost control procedures, particularly in developing regions of the world. Since the end of the Second World War, the use of sophisticated cost control procedures in managing and controlling project costs have been accepted and applied widely in many parts of the world such as the United States and the United Kingdom. These procedures are important in a growing economy to ensure delivery of projects on time and within budget, but they are equally important during an economic recession when project viability becomes marginal. In the early 1990s, the construction industry in Thailand played a critical role during a period of strong economic growth. Construction cost control was not a major concern as developers rushed to capitalize on the booming market. In the late 1990s, the economy of Southeast Asia sank into recession. Project cost control became a critical issue for the developers as well as the construction companies in managing construction projects. A significant number of projects in Thailand in the late 1990s had significant cost overruns. Cost overruns had been a problem during the high growth period in the early 1990s, but demand overcame the problems created by poor cost control. The use of good project cost control procedures has become a concern of project investors and construction companies in Thailand since the recession of the late 1990s. Project managers and developers are now aware that the failure of a cost control system or use of a poor system can lead to project failure. Project cost control methods need to be improved in Thailand to ensure that owners and contractors manage construction costs and meet project goals on time and within budget. In this study, project cost controls in the United States and Thailand will be examined. These procedures will be analyzed to identify their similarities and differences. The causes and solutions for cost overruns in the two countries will also be examined. The results from the study will illustrate how the project cost control procedures used in the United States can be applied to the construction industry in Thailand to improve the procedures used by Thai contractors.

Abstract:
The project cost overruns instigated through the loss of construction materials lowers the profitability of each stakeholder significantly. The purpose of this single case study was to explore strategies managerial leaders of a large construction firm used to counteract material cost overruns successfully. The diffusion of innovation theory was the conceptual framework for this study. The target population consisted of 6 managerial leaders with experience in large construction projects adhering to waste management standards and industry certifications. Data were collected using semistructured interviews and review of company documentation. The data analysis approach involved the content analysis research method to interpret and code the verbatim transcriptions of interviews into categories. The 2 principal categories from the study data were material management and planning and the supply chain and logistics. The results of the study yielded evidence of 2 strategies to counteract the material cost overruns, which were to strengthen partnerships with the suppliers and to hold regular audits at the project sites. The implication of this study for social change includes the potential to conserve depleted land minerals and valuable land reserves from becoming landfill by providing construction managers with information about strategies to counteract material cost overruns.

Abstract:
A project can be defined as a temporary work that is within the scope of time and budget in terms of achieving a project goal. Due to the fact that construction projects are unique and usually very complex, project management therefore requires a working method that is adapted to the prerequisites of the project. The project manager's responsibility to follow up on the budget and ensure that resources such as working hours and consulting services are distributed correctly, is becoming increasingly challenging as the change paradox shows that flexibility decreases and costs for changes increase as the project progresses. Exceeding the project budget in construction projects has today become a global phenomenon and involves several negative social effects. Scientific studies show that the increased costs can be derived from deviations such as additions and changes during the construction project. On the other hand, there are perceived gaps in the literature for which factors affect the extent of these and thus became the study's area of ​​investigation. Based on the scientific gap, the study aims to analyze the startup process in smaller construction projects with regard to identifying the factors that have an impact on additions, but also to review how project managers can proactively manage these factors in order to reduce the risk of increased deviations. To answer the research questions and purpose, a qualitative case study has been applied to a global consulting company in the construction industry, where semi-structured interviews were conducted with five project managers at the company.   The result of the study shows that project managers do not take preventive measures or work to prevent deviations in the startup process. Based on a thematic analysis of the results, factors with an impact on deviations have been identified in three areas; systematics, communication and experience and competence. The study has shown that increased costs for additions and changes can be deduced from different approaches to project management and misleading information, inadequate requirement specification that leaves room for own interpretation, unspecified communication channels, conflicts, lack of competence and abrupt completions of the project. In order to achieve a more proactive startup process in order to prevent increased costs for additions and changes, project managers should ensure a clear requirement specification by discussing important issues and decisions, requirements and expectations with support from templates and checklists. To avoid misunderstandings and conflicts, a communication plan can be established. Finally, the choice of project model should be established and routines for final reporting should be introduced to create a learning organisation that increases the project managers' self-insight and competence regarding increased costs for additions and project changes. The theoretical contribution of the study is the identified factors within three areas as well as suggestions for how project managers can facilitate the management of additions in the startup process of construction projects.
Ett projekt kan definieras som ett tillfälligt arbete som förhåller sig inom ramarna för tid, budget och omfattning i avseende att uppnå ett projektmål. Med anledning av att byggprojekt är unika och vanligen mycket komplexa, är projektledare i behov av verktyg och arbetsmetoder som anpassas utifrån projektets förutsättningar. Projektledarens ansvar att följa upp budget och se till att resurser såsom arbetstid och konsulttjänster fördelas rätt, blir allt mer utmanande under projektets gång då ändringsparadoxen påvisar att flexibiliteten minskar och kostnader för ändringar ökar i takt med projektets fortgång. Överskridande av projektbudget inom byggprojekt har idag kommit att bli ett globalt fenomen och innebär flera negativa samhällseffekter. Vetenskapliga studier visar att de ökade kostnaderna kan härledas till tillägg och ändringar under byggprojektet. Däremot upplevs det finnas luckor i litteraturen för vilka faktorer som inverkar på omfattningen för dessa och detta blev således studiens undersökningsområde. Utifrån det vetenskapliga gapet syftar studien till att analysera uppstartsprocessen i mindre byggprojekt i avseende att identifiera de faktorer som har en inverkan på tillägg, men även till att se över hur projektledare kan hantera dessa faktorer för att minska risken för ökade kostnader vid tillägg. För att besvara rapportens frågeställningar och syfte har en kvalitativ fallstudie tillämpats hos ett globalt konsultbolag inom byggbranschen, där semistrukturerade intervjuer genomfördes med fem projektledare på företaget. Resultatet av studien visar att projektledare inte vidtar förebyggande åtgärder eller arbetar för att förhindra tillägg i uppstartsprocessen. Utifrån en tematisk analys av resultatet har faktorer med en påverkan på tillägg kunnat identifieras inom tre områden; systematik, kommunikation samt erfarenhet och kompetens. Studien har visat att ökade kostnader vid tillägg och ändringar går att härleda till olika tillvägagångssätt vid projektledning och vilseledande information, bristfällig kravspecifikation som lämnar utrymme för egen tolkning, ospecificerade kommunikationsvägar, konflikter, bristande kompetens hos projektledaren samt abrupta projektavslut. För att uppnå en mer proaktiv uppstartsprocess i syfte att förhindra ökade kostnader vid tillägg och ändringar bör projektledare säkerställa en tydlig kravspecifikation genom att diskutera viktiga frågor och beslut, krav och förväntningar med stöd från mallar och checklistor. För att undvika missförstånd och konflikter kan en kommunikationsplan upprättas. Avslutningsvis bör val av projektmodell fastställas och rutiner för slutrapportering införas för att skapa en lärande organisation som ökar projektledarnas självinsikt och kompetens vad gäller ökade kostnader för tillägg och ändringar. Studiens teoretiska bidrag är bidragsfaktorer som identifierats inom tre områden samt förslag till hur projektledare kan underlätta hantering av tillägg i uppstartsprocessen av byggprojekt.

Abstract:
Quantity Surveyors are considered as the most qualified cost specialists in the construction industry, with their experiences and skills in cost management and control as well as contract management. However, this role is not well recognized in Sweden compared to other countries such as the UK where it’s originated from. And so, the construction industry in Sweden uses other professions for the roles that were supposed to be done by quantity surveyors or cost managers. As a result, the quantity surveyors that have penetrated the Swedish construction industry, face challenges to perform their duties specifically in this case, cost control due to several circumstances. This study has looked into different contractual challenges that face quantity surveyors while performing cost control in building projects. Also, recommendations have been made to help mitigate these challenges and improve cost control in projects. In this master thesis, qualitative study has been performed where quantity surveyors were interviewed regarding cost control and the contractual challenges, they face in building construction projects. The findings were analysed with a theoretical framework and discussed together with previous research and knowledge and in this study principal – agent theory was used. The results of the study showed that poor planning, late involvement of the quantity surveyors in projects, lack of effective communication and poor contract management are the main challenges that face quantity surveyor in performing cost control in building projects. To overcome these challenges, the author suggests that there is a need of increasing awareness on the importance of having quantity surveyors and clearly establish their roles in projects, have proper communication plan, proper contract management and improve skills on quantity surveying software.
Kvantitetbesiktningsman anses vara de mest kvalificerade kostnadsspecialisterna inom byggbranschen, med sina erfarenheter och färdigheter inom kostnadsstyrning och kontroll samt kontrakthantering. Denna roll är dock inte välkänd i Sverige jämfört med andra länder som Storbritannien där den härstammar från. Och så använder byggbranschen i Sverige andra yrken för de roller som skulle göras av kvantitetsmätare eller kostnadsansvariga. Som ett resultat står de kvantitetsmätare som har trängt igenom den svenska byggbranschen inför utmaningar att utföra sina uppgifter specifikt i detta fall, kostnadskontroll på grund av flera omständigheter. Denna studie har undersökt olika avtalsmässiga utmaningar som möter kvantitetsmätare när de utför kostnadskontroll i byggprojekt. Dessutom har rekommendationer gjorts för att mildra dessa utmaningar och förbättra kostnadskontrollen i projekt. I detta examensarbete har en kvalitativ studie utförts där kvantitetbesiktningsman intervjuades angående kostnadskontroll och de kontraktsmässiga utmaningar som de står inför i byggprojekt. Resultaten analyserades med en teoretisk ram och diskuterades tillsammans med tidigare forskning och kunskap och i denna studie användes princip - agentteori. Resultaten av studien visade att dålig planering, sen involvering av kvantitetsmätarna i projekt, brist på effektiv kommunikation och dålig kontrakthantering är de viktigaste utmaningarna för kvantitetsmätaren när det gäller att utföra kostnadskontroll i byggprojekt. För att övervinna dessa utmaningar föreslår författaren att det finns ett behov av att öka medvetenheten om vikten av att ha kvantitetsmätare och tydligt fastställa sina roller i projekt, ha korrekt kommunikationsplan, korrekt kontrakthantering och förbättra färdigheterna i kvantitetsmätningsprogramvara.

Abstract:
Senior managers fail to control time and costs of construction projects despite available advanced project management tools. Based on project management theory, the objective of this multiple case study was to explore the strategies senior managers use to reduce cost overruns and schedule delays in construction projects. Primary data were obtained from semistructured interviews with 3 senior managers from different construction project management companies who have successfully managed construction projects in Qatar. Data analysis process included a modified Van Kaam method. The transcribed interviews were interpreted and coded to generate themes and were validated through member checking and archival documents. The most centralized themes included (a) master planning, (b) processes and procedures, (c) managing design stage, (d) procurement management, (e) use of proper software, (f) setting project cost and time, and (g) deciding clear scope. A construction project may not succeed without appropriate planning for all stages of the project lifecycle. Managing the approval of the project components during the design stage contributes to reducing changes during construction, which is helpful to control cost and time. The project processes and procedures are meaningful roadmaps for the managers and decision makers. The implications for positive social change include the potential to maintain a cleaner Earth by reducing design and construction wastes. Reducing wastes improves the cost of construction and provides opportunities for people to own property at more affordable costs.

Abstract:
While wastage of materials has become a serious problem requiring urgent attention in the Nigerian Construction Industry, cost overrun is a problem, which affects 90 percent of the completed projects in the world; the argument on how to reduce/eliminate cost overrun has been on-going for the past 70 years; as the on-site wastage of materials leads to increases in the final project cost. Studies from different parts of the world have shown that construction-material waste represents a relatively large percentage of the production costs. Consequently, as a result of low levels of awareness, the Nigerian construction industry pays little attention to the effects of generated material waste on cost overruns. Thus, this research aimed to investigate the relationship between material waste and cost overrun in the Nigerian construction industry. A comprehensive review of the related literature revealed that all material waste causes are related to cost overrun causes at both pre-contract and post-contract stages of a project; but not vice versa. The mixed method (quantitative and qualitative) approach that is rooted in the positivist paradigm was adopted for this study. Abuja, the federal capital territory of Nigeria was the selected geographical scope of this research, out of which thirty-one (31) construction projects were purposeful selected (projects to the value of 100 million Rand/1.6 billion Naira and above).The research instrument was an interview guide used in conjunction with a tick box. Other sources of data included field investigation (measurement of onsite material waste) and the collection of archival records from bills of quantities, project records, and specifications. Analyses of the findings lead to the conclusion that a relationship exists between material waste and cost overrun; at the pre-contract and at the post-contract stages of a project. The implication is that an increase in material wastage on-site leads to a corresponding increase in the amount of cost overrun, regardless of the percentage allowance for material waste in the process of bill preparation. The study also concluded that the average percentage contribution of material waste to project-cost overruns is four (4) percent. Material-waste sources, causes, and control measures were found to have significant effects (very high, high, medium, low, and very low), in causing or minimising cost overruns at both pre-contract and post-contract stages of projects. The research has developed a conceptual model for the management of material waste and cost overruns in the construction industry based on the results and informed by the theoretical framework. The research has also developed a mathematical model for quantifying the amount of material waste to be generated by a project; as well as a mathematical equation for the effective management of material waste and cost overrun for projects. The study has achieved its aim of establishing an understanding of the issues leading to the relationship between material waste and cost overruns, as well as their management in the Nigerian construction industry. The study recommends that the management of material waste and cost overrun should be revised, based on the findings of this research and included as part of the procurement process. The mathematical models for quantification of onsite material waste, and the mathematical equation for managing material waste and cost overruns developed in the study, could be usefully adopted to improve management of material waste and cost overrun in the Nigerian construction industry.

Abstract:
Abstract Background Construction industry greatly affect the environment in the aspect of energy consumption and its contribution to global warming. Accordingly, green building construction is significantly growing, which makes it an interesting topic for researchers. Green buildings are defined as buildings constructed according to sustainability standards that keeps the natural environment healthy. However green construction is challenging in the economic aspect and the cost efficiency. Based on the researches, uncertainty is a main reason for cost overrun. In addition, procedures in early stages of the project is of great importance and have influence on the costs. However, further study is needed to identify the differences between conventional and green construction companies regarding uncertainties, cost overrun, and uncertainty mitigation techniques. Purpose The focus of this research is to compare two types of construction companies (conventional and sustainable) in the aspect of uncertainties as inevitable part of risks, it’s effect on cost overrun, and techniques being used in the pre-construction phase to mitigate them. Method Multiple-case study was conducted, and two construction companies were selected of each type. This research is a qualitative study with abductive approach. The empirical data were collected by conducting semi-structured interviews with several positions in each company. Also, secondary data were collected from companies’ archival reports and documents, and from scientific blogs. Conclusion The findings of this research indicate that sustainability creates fields of uncertainties extra to those existing in conventional construction. The study revealed the direct effect of uncertainties on cost, and the indirect effect by generating events which cause overruns in cost. Moreover, Companies work on improving managerial skills in the preconstruction phase to mitigate the effect of uncertainties and to reduce probability of cost overrun occurrence in both sustainable and convention construction companies. While in sustainable construction, additional techniques and efforts are needed as technology, artificial intelligence, and hiring external resources and staff.

Abstract:
Infrastructure project delays and cost overrun are caused by ineffective use of organizational skills, processes, and resources by project managers in the construction industry. Cost overrun and schedule delay in Qatari infrastructure projects have had damaging effects on the national economy by way of claims and litigation, contractual disputes, delays in dependent projects, and project abandonment. The purpose of this qualitative case study was to explore the perceptions of project managers regarding how they utilize capacity-planning practices to mitigate project schedule delay and cost overrun in government-funded infrastructure projects in Qatar. This study was framed by three conceptual models developed by Gill to outline the capacity management needs within a construction company: (a) the time horizon model, (b) the individual-organization-industry levels model, and (c) the capacity development across components model. Date were collected from semistructured interviews with 8 participants, observational field notes, and archival data regarding Qatari infrastructure project managers' experiences in capacity-planning practices. Thematic analysis of textual data and cross-case synthesis analysis yielded 5 conceptual categories that encompassed 15 themes. The conceptual categories were (a) resources to meet performance capacity, (b) knowledgeable and skillful staff, (c) short- and long-term planning strategy, (d) cost overrun issue, and (e) time management. Findings may be used to promote timely completion of infrastructure projects, which may benefit citizens, construction companies, and the economy of Qatar.

Abstract:
Cost management forms a major discipline in delivering construction projects of different sizes and complexity. Traditional cost management systems are mostly based on principles enacted several decades ago. A notable feature of these traditional cost management systems is that key information required for critical decisions is usually produced too late, and is often too aggregated and configured in a form that is not amenable to the requirements for current project management practice. Other problems associated with traditional cost systems relate to inadequacies in estimating and cost control processes and particularly the lack of integration of cost management across the whole project. The lack of integration means measurements provided by traditional cost systems do not sufficiently align with the goals and objectives set for the project. To address these inherent weaknesses in the current practice of cost management, a number of studies have argued for an integrated alternative that better responds to the information demand and decision making need to be developed. The thesis presents the development of a solution to such an integrated cost management system. The developed solution addresses the gaps of the traditional option by integrating the stages making up the whole life cycle of the project to enable professionals gain an appreciation of the ramifications of any early decisions made. The investigation conducted to support the development of the integrated cost management system and the applied model addresses user requirements and determination of the system boundary conditions for efficacious use by key decision makers. The new cost management system developed achieves a linkage of the planning and control stages into one, with a continuous stream of cost management information in both stages. The integration ensures that cost information is more relevant to the circumstances of the modern project manager.

Abstract:
The execution of construction projects commands a myriad of technological, human, organisational and natural resources. However, the construction and engineering undertaking of these projects are frequently overshadowed by economic difficulties, such as the high costs of construction materials, that have a negative impact on project costs. Cost overruns have been determined as a phenomenon continually plaguing the construction industry in both private and public sectors, and very few projects are completed within cost parameters. This research evaluated the barriers to the use of innovative cost control techniques during the construction phase, and determined the level of cost overruns on construction projects in South Africa; identified innovative cost control techniques used by construction firms on construction projects; established the optimal innovative cost control technique used in the South African construction industry; and uncovered the relationship between the level of use of innovative cost control techniques on construction projects and cost overrun. Questionnaires were the chosen instrument for data collection and were circulated via Survey Monkey. A total of 123 questionnaires were returned, and they provided the base for the computation of study results. Statistical tools employed in the study included percentages, mean item score (MIS), and frequency distributions. A scatter plot was used to distinguish whether there was a correlation between the cost performance of projects and level of innovativeness by establishing a line of best fit through the set of the two variables. A line of best fit in the positive direction indicates that increased levels of innovativeness improves the cost performance of projects, while a line of best fit in the negative direction indicates that increased levels of innovativeness does not enhance project performance. The relationship between the level of innovative cost control techniques usage in construction projects and cost overrun was determined to be negative. This led to the conclusion that construction professionals are limiting themselves and are not exploring alternative or innovative cost control techniques. They were focused on project efficiency and productivity rather than cost overruns. Innovative cost control techniques identified in the study were Earned Value Analysis (EVA), Last Planner System (LPS), 4D Scheduling, Fuzzy Project Scheduling, Integrated critical path and Line of Balance, and Reserve Analysis. Study findings determined that the critical contributors to cost overruns included tight project budgets, project complexity, a high frequency of change orders by clients and financial difficulties encountered by contractors. Perceived barriers to the implementation of innovative cost control techniques in projects by participants included a poor scope definition, a lack of training and technical skill of project personnel, poor understanding of cost analysis and variables involved in cost planning. It also emerged that projects cannot meet project objectives, and construction organisations are not making use of the right tools and techniques to monitor and control construction costs. The research findings have shown that professionals have limited knowledge of innovative cost control techniques. This also concludes that they are not taking advantage of the features of new innovative techniques to tackle complex projects. This, therefore, means that complex projects will continue to experience cost overruns. This study concludes that top management of construction organisations are not training their staff to embrace new technologies and innovation. To address the barriers to the use of innovative techniques, there should be increased investment on the part of construction organisations toward affording their workforce the relevant training, knowledge and technical skill required to implement the modern techniques for cost control identified in the report. The cidb should organise seminars and workshops on the usefulness and importance of innovative cost control techniques, and workers should embrace self-development and change. Government should implement policies on the use of innovative cost control techniques for their projects, and construction organisations should develop capacity in line with innovative cost control techniques.

Abstract:
This research project constitutes an attempt to improve the construction industry's change management process by introducing the Form 'X' Control Mechanism as the means of establishing an effective method of project control. The traditional practice in the construction industry of appointing the principal designer as team leader has been challenged with the main criticisms on the traditional practice being his, or her, lack of managerial ability and his, or her, failure to control the financial aspects of the project. The traditional approach has remained essentially unchanged for more than a century but it has become increasingly questioned as the primary means of design management. One aim of the research, therefore, was to ascertain whether the traditional practices currently is use in the United Kingdom and Hong Kong could be improved upon. The research began by examining basic systems and project management concepts and noted the development of project management systems and structures for the construction industry. This was illustrated by reference to a number of articles and it was possible to argue that the industry lacked a comprehensive change control methodology. The research also provided evidence that the mechanisms used to exercise control in manufacturing industries could not be used to exercise control over construction projects. This is due, in the main, to the relatively short duration of construction projects and the transient nature of project personnel. Having examined the difficulties, it has been possible to devise a control methodology which couples communication and control and this mechanism has been adapted to fit existing industry practices. Using this criterion it was possible to formulate a control procedure which obviates the difficulties which can arise using the traditional approach to change management. The Form 'X' mechanism requires the design team to quantify, in financial and programme terms, the effect of design or construction changes, and to obtain the client's specific authority prior to revising the works. In doing so the Project Manager is able to determine the magnitude of all changes in terms of time, money and quality. The system is sufficiently flexible to enable it to be used world-wide, on projects of varying contract values and duration, and it requires only minor modifications to meet the provisions of the standard building and civil engineering conditions of contract. A variant of the proposed methodology was introduced by Hong Kong's Mass Transit Railway Corporation and utilised on a number of projects. These contracts were examined in detail, as were a number of Mass Transit Railway Corporation contracts which utilised the traditional approach to project control. The analysis showed that all of the projects on which the Form 'X' system had been used had been completed close to their original contract value whilst a number of the projects which did not use the control methodology suffered from significant cost over-runs. It was concluded that the Form 'X' methodology successfully eradicates many of the control problems which permeate the traditional approach to change management embodied in the standard conditions of contract for building and civil engineering works. The Form 'X' control approach was also shown to be popular with the Hong Kong Mass Transit Railway Corporation's senior management team, as well as with the consultants employed in the construction of the railway. The conclusion of the research project is that the Form 'X' procedure is a highly successful change control methodology which could be used throughout the world on a wide variety of building and civil engineering projects.

According to findings presented in literature, construction projects are restrained within budgeted cost. Hence, the operational system is challenged within prohibitive cost limits to deliver projects at a stipulated time and at a satisfactory quality. This has prompted the intention of establishing effective management of cost constraint on building project delivery in South Africa. Data for the main study were collected through observations, semi-structured and unstructured qualitative interviews and quantitative close-ended questionnaires administered to construction stakeholders working in the Western Cape and Gauteng provinces, South Africa. Findings are that the following are factors that affect cost during building production process: additional works without contractual procedure, inadequate co-ordination of design phase and construction phase during production by project managers, financial mismanagement, frequent changes in design, cost of materials in the market, fluctuation of price of materials. Additional findings are proper monitoring and controlling at stages during production, procurement of competent contractors and subcontractors, involvement of experienced professionals in production, proper briefing by the client during production process, targeting quality during production, prompt decision taking during production, and the establishment of effective communication systems on site during production, frequent changes in building design by the client during production affect construction cost; frequent changes in building design during production cause rework; changes in building design during construction caused by errors and omissions detected affects quality of project delivered; and specification due to procurement of new materials during construction causes changes in building design, labour productivities, wrong planning for machine usage on site, late delivery of equipment during production and unanticipated increases in prices of building materials. Late delivery of materials also affects production process. Regular meetings on site will promote efficient productivities of human resources, team work on site during production, general progress reports on site during production, projects schedule/timetable for production and work programmes for site activities. The study concluded by recommending that proper adoption of these findings by the South African construction stakeholders during production processes will enhance delivery of building projects at reduced construction resources, at the standard of quality expected, at the time stipulated, at the budgeted cost specified, and to the satisfaction of the client. Interest will be achieved as illustrated under each objective of the research study. This research recommends further investigation of the effects of building material supply management during production processes in the South African construction industry.

Abstract:
The construction industry was considered very important as it contributed a significant part of the Gross Domestic Product (GDP) for the economic development of any country. Construction projects appeared to have high expenditures and complex processes that involved a wide range of participants, stakeholders, investments, and technologies. This continued to increase construction project overheads considerably. Project overheads were common to multiple cost objects, but cannot readily be allocated directly to particular construction activities. The traditional costing system added project overheads to construction cost on a percentage basis, which often provided inaccurate distributions for most of the activities. The current cost accounting management approach focused too much on satisfying external standard requirements, consequently paying little attention to internal cost management improvements. This research proposed an Activity-Based Cost Controlling (ABCC) model through the identification of overheads in construction projects, the analysis of Critical Success Factors (CSFs), and application of the Activity-Based Costing (ABC) system for improving the Cost Management and Controlling Practices (CMCPs) of construction project overheads. The critical realist philosophical stance with multiple case studies was adopted for this research. Data collection used questionnaire survey, project documentation, observations, and interviews. Data analysis utilised descriptive statistics, Analytic Hierarchy Process (AHP), the ABC system and Earned Value Measurement System (EVMS), content analysis and cognitive mapping. Forty seven generic overheads were identified, however, eight overheads were eliminated for construction projects. The remaining 39 overheads were the most often present in construction projects and were categorised into Unit, Batch, Project, and Facility levels. 40 CSFs were identified and grouped into eight, out of which three were identified as priority areas (requirement of a robust method and tool - METOOL, understanding the market condition - MARCON, and managing project complexity - PROCOM). The ABCC model was developed using three themes: the construction project overheads, the ABC system, and the CMCPs. The top three priority CSFs were incorporated into the CMCPs’ tools and techniques for implementation of the ABCC model. The opinions of experts (senior and operational management levels) were used to validate the ABCC model, which generated 36 concepts that were incorporated into the model during the refinement stage. Therefore, the ABCC model was developed for improving the management of construction project overheads to increase the body of knowledge.

ENGLISH ABSTRACT: The construction project environment is dynamic and prone to change. Project change can be defined as any event that alters a project’s original scope, execution time or the cost of the works. Improper management of the projects’ changes could therefore adversely impact on the actual cost and duration of the project which may lead to project cost overruns and even claims and legal disputes. During the construction phase of a project, change affects every aspect of productivity – the planned schedules and deadlines, work methodology, resource procurement, as well as the budget and thus it could prevent the achievement of the project objectives. A project manager, therefore, wants to limit the number of change to a project. However, during a construction project there may be quite a number of changes. Managing a construction project is difficult, in that all the relevant information is rarely available at the initial stage of a project to enable one to plan and design the project accurately and make the best possible decisions. As information becomes available during the construction phase of the project, it can lead to various changes. Design errors or variations, unforeseen site conditions and vagueness in the original scope are but some of the reasons for change. No matter the size of the change, each alteration to the works has a cost, time and risk implication. Due to tight time constraints on most projects, every change requires quick, robust decision making, so as not to delay the project, which therefore results in changes not being comprehensively evaluated. Decisions are often made on intuition or experience, without an assessment of the risks involved or the influence on the cost of the project and without applying well-known project management techniques. The aim of this research was to determine what a change management process for a civil engineering project should look like, specifically the cost and risk management of changes. It investigated the current state of change management of construction projects in practice, by doing a case study and various interviews with project managers. Based on the findings of the research and the industry requirements, a model was developed for managing the costs and risks of changes. The Model was validated by means of an expert evaluation review. The change management model developed as part of this thesis can be used to analyse the cost, time and quality impact of the change, and to do a detailed risk assessment. The Model also reviews the proposed change in order to determine whether the change is necessary. It is a generic tool that can be used by engineers and their project team to enhance the management of changes that happens during the construction phase of a project for any civil construction project.
AFRIKAANSE OPSOMMING: Die konstruksie omgewing is dinamies en geneig tot verandering. Projek verandering kan gedefinieer word as enige gebeurtenis wat die projek se aanvanklike omvang verander of lei to verlenging van die tydsduur of vermeerdering van die koste van die projek. Wanbestuur van projek veranderinge kan ‘n nadelige impak op die projek kostes en tydsduur hê wat kan lei tot oorskryding van die begroting en selfs eise en regsdispute. Verandering kan elke aspek van produktiwiteit tydens die konstruksie fase van ‘n projek affekteer. Dit affekteer die beplande skedules, spertye, werk metodologie, hulpbron bestuur, asook die begroting. Dus kan dit verhoed dat die projek doelwitte bereik word. ‘n Projek bestuurder wil daarom die hoeveelheid en omvang van veranderinge beperk. ‘n Konstruksie projek kan egter heelwat veranderinge ondergaan. Om ‘n konstruksie projek te bestuur is moeilik aangesien al die relevante informasie selde beskikbaar is tydens die begin fases van ‘n projek wat nodig is om die beplanning en ontwerp van die projek so akuraat moontlik te doen en die regte besluite te neem. Soos informasie beskikbaar raak tydens die konstruksie fase van die projek, lei dit dikwels to verskeie veranderinge. Ontwerp foute of variasies, onvoorsiene terrein toestande en onduidelikheid oor die projek omvang is van die redes vir veranderinge. Ongeag die grootte van die verandering het elke wysiging tot die projek ‘n koste, tyd en riskiko implikasie. As gevolge van tydsbeperkinge vereis elke verandering vinnige en kragtige besluitneming om sodoende nie die projek te vertraag nie. Dit lei daartoe dat veranderinge nie omvattend geëvalueer word nie. Besluite word dikwels geneem op intuïsie of ervaring, sonder 'n beoordeling van die risiko's wat betrokke is of die bepaling van die invloed op die koste van die projek, en sonder die toepassing van erkende projek bestuur tegnieke. Die doel van hierdie navorsing was om vas te stel hoe 'n verandering bestuur proses moet lyk vir ‘n siviele ingenieurswese projek, spesifiek die koste en risiko bestuur van die verandering. Die huidige stand van verandering bestuur van konstruksie projekte in die praktyk is ondersoek deur middel van 'n gevallestudie en verskeie onderhoude met die projek bestuurders. 'n Model is ontwikkel vir die bestuur van die koste en risiko's van veranderinge gebaseer op die bevindinge van die navorsing en ook die vereistes van die bedryf. Die model is getoets met behulp van evaluering deur professionele ingenieurs. Die verandering bestuur model wat ontwikkel is as deel van hierdie proefskrif kan gebruik word om die koste, tyd en kwaliteit impak van ‘n verandering te analiseer, asook om 'n omvattende risiko assessering te doen. Die model hersien ook die voorgestelde verandering om te bepaal of die verandering nodig is. Dit is 'n generiese hulpmiddel wat deur ingenieurs en hul projek span gebruik kan word vir die bestuur van die veranderinge wat tydens die konstruksie fase van siviele projekte plaasvind.

Thesis (MTech (Business Administration in Project Management))--Cape Peninsula University of Technology, 2019.
There is a need to draw a balance between satisfying needs, be they of the customer or the beneficiaries of the project, and that of maximising the utilisation of resources. Value management seeks to merge all aspects of the project process, and to find a balance between satisfaction of the project‟s needs and the stakeholder‟s interests. This technique is meant to improve the reconciliation and value of differing judgements and priorities to improve on the deliverables of the project. Consequently, the principles of defining and adding measurable value focuses on reaching the objectives, and finding solutions to problems before they appear. Therefore, the end results become an innovative way of integrating all operational activities, which enhance pre-emptive, risk aversive management. Value management is considered as a critical aspect in the effective management of project processes to reduce the high project failure rate in the construction industry. Part of the purpose of this study is to bring about awareness and knowledge of the effective use of the value management tool. This empirical research focused on project managers and other project practitioners who are tasked with the execution of project processes. A total of 125 respondents was drawn from the sampling frame. A structured questionnaire was used for the purpose, and collected data was captured and analysed, using the SPSS tool and an Excel spreadsheet. Relationships in the illustrations were interpreted and presented, forming the basis on which findings, conclusion and recommendations were made. A questionnaire has structured closed-ended questions (quantitative) and open-ended questions (qualitative) to complement each other. A mixed method approach (qualitative and quantitative) was applied to take advantage of the benefits of these two methods. The qualitative research applied a content analysis of the collected data.

Abstract:
A shortage of skilled craft labor in the North American construction industry has been an unfortunate cyclic trend since the late 1980s. This shortage has been reported and discussed frequently by numerous past studies in the context of construction industry. The 2008 U.S. recession was at least one period when the craft shortage temporarily improved, as witnessed by spikes in construction unemployment rates above 20% due to the work slowdowns. However, the current economic recovery period is once again experiencing craft shortages in some sectors of the U.S. construction industry. Although the past literature provides wealth of information about influence of craft labor shortage on construction project, less attention has been given to quantifying the impact of craft labor availability on construction project performance. The primary contribution of this study to the body of knowledge is to fill the gap in existing literature by quantitatively modelling and elucidating the influence of craft labor availability on construction project performance as measured by safety, schedule, productivity and cost. Data from 97 construction projects completed in the U.S. and Canada between 2001 and 2014 were collected from two data sources. A number of t-tests and regression analyses were conducted in both databases to examine the significance of the influence of craft labor shortage on construction project performance. The primary analysis shows that projects that experienced craft shortages underwent significant higher growth in cost overrun, time overrun, safety incident and also lower productivity compared to projects that did not. Further analysis on two databases returned the following models: 1) a Poisson regression model that demonstrates a positive exponential relationship between increased craft worker recruiting difficulty and Occupational Safety and Health Administration (OSHA) Total Number of Recordable Incident Cases per 200,000 Actual Direct Work Hours (TRIR) on construction projects. 2) a statistically significant correlation between increased craft recruiting difficulty and lower project productivity and higher schedule overruns 3) a multiple regression models that demonstrate a relationship between increased construction cost overrun with two variables of increased actual cost and increased craft staffing difficulty. These models are intended to be used by project management team to perceive the risk that skilled craft labor variability poses on project safety, productivity, time, and cost performance. In addition, understanding the level of impact that craft shortages are having through robust statistical analyses is a first step in developing the motivation for industry leaders, communities, and construction stakeholders to address this challenge.

Abstract:
The construction industry represents a significant part of the Gross Domestic Product, (GDP) in the UK. It employs around 1.4 million people and has averaged around 7.5% of GDP over recent years. Although the industry is of major importance to the UK economy, it still under achieves. Many projects run over budget and are completed late to schedule and a lot of resource is invested in making good defects, repair and replacement and in litigation (Latham 1994). These shortfalls in the construction industry were investigated by EGAN 1998 in his report, Rethinking Construction. EGAN proposed five key drivers for change, these consisted of committed leadership, focus on the customer, integrating the processes and teams, a quality driven agenda and commitment to people. Targets were set to gauge the improvements to the UK, these include 10% reduction in capital cost and construction time, 20% reduction in defects and accident, 20% increase in productivity and profitability and 10% increase in predictability of project performance. This thesis reviews one of the most important drivers, which is the improvement to integrate construction processes through improved project controls. The aim of the Thesis was to investigate by a literature review, a questionnaire and survey and three audits of client’s processes and work practices how Project Controls was currently operating to deliver Projects on time and within budget. It was then necessary to review (how based on best practice) current Project Control processes and systems could be improved. The improvements are portrayed by the development a series of “road maps” and “tool kits” demonstrating how processes and systems could be improved. This research thesis investigates the status of Project Controls in the UK and develops methodologies to improve controls. The investigation of Project Controls is based on five pieces of work, namely; i) A literature review of current practices; ii) The development of a questionnaire and survey results; iii) Three client reports of work carried out by the author. The five pieces of work were then contextualised to form a commentary of findings and recommendations for improvement. The recommendations were then linked to a methodology for improvements to the key elements of Project Controls. The aims of the thesis were achieved in that many issues of weakness were identified in current Project Control systems and processes and “road maps” were developed identifying in detail how best practice should be adopted. The thesis identifies major weaknesses in control of major projects with examples such a Pharmaceuticals, Building construction and Road construction industries demonstrating minimal understanding of the concepts and benefits of effective control. It could be described as disappointing series of examples of why some of our Industries fail to deliver to cost and schedule. However, the thesis does layout via “road maps” how improvements could be made, this knowledge has in part been shared with some clients in the Pharmaceutical and Road construction. The thesis therefore does demonstrate a contribution to knowledge and some of its recommendations are being implemented in practice. The primary conclusions of the Thesis indicates that with the exception of Oil & Gas companies there are major gaps between what is accepted as best practice and what is happening in Industry with regards to Project Controls. There is a lack of understanding at Project Control engineer and Project Manager Level. There is a need for additional training in particular for Project Managers as their understanding and ability to see the benefits is paramount to driving forward effective planning and control for projects. Also it is necessary that robust Project Control procedures are established in all industries to integrate the cost and planning disciplines to ensure a common approach to best practice is adopted.

Abstract:
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.

Abstract:
En la actualidad, el sector construcción ha sido muy relevante en el crecimiento del PBI del Perú. El crecimiento ha sido generado por la cantidad de obras que se están realizando en todo el país; debido a este crecimiento, las micro y pequeñas empresas constructoras han tomado mayor relevancia entre los últimos años por su contribución en proyectos de edificaciones multifamiliares. Se puede denotar la importancia que tienen las MYPEs debido a su aporte al PBI, pero, al no tener un control adecuado de gestión, han tenido problemas para gestionar sus proyectos por lo que su utilidad se ha visto afectada considerablemente. Estas pérdidas han generado que muchas MYPES detengan su participación en el mercado indefinidamente, afectando a la contribución del PBI del sector. Para solucionar la mala gestión de proyectos en las obras de edificaciones multifamiliares, se ha propuesto una guía para el desarrollo de una Project Management Office (PMO) Low Cost, para Micro y Pequeñas empresas que no tengan el capital necesario para invertir en una Project Management Office estándar. Esta guía pretende ser validada a través del método Delphi, recurriendo a los expertos del medio local que tengan experiencia en Gerencia de Proyectos. Los resultados esperados son los de una mejora en el nivel de madurez de las MYPEs tomando en cuenta la mejora en la gestión de proyectos.
Currently, the construction sector has been very relevant in the growth of Peru's GDP. The growth has been generated by the number of works being carried out throughout the country; Due to this growth, micro and small construction companies have become more relevant in recent years for their contribution in multi-family building projects. The importance of the MYPEs due to their contribution to the GDP can be denoted, but, as they did not have adequate management control, they have had problems managing their projects and their utility has been considerably affected. These losses have caused many MYPES to stop their participation in the market indefinitely, affecting the contribution of the sector's GDP. To solve the mismanagement of projects in the works of multi-family buildings, a guide has been proposed for the development of a Project Management Office (PMO) Low Cost, for Micro and Small companies that do not have the necessary capital to invest in a Project Management Standard Office. This guide is intended to be validated through the Delphi method, using experts from the local environment who have experience in Project Management. The expected results are those of an improvement in the maturity level of the MYPEs taking into account the improvement in project management.

Abstract:
The present work deals with the study and analysis of the simultaneous optimization of time, cost and quality by using artificial intelligence technique; The approach is based on the use of genetic algorithms implemented in Matlab applied to a case study, the construction of a new University Campus in Cesena, focusing on the external walls of the building itself. The objective is to find a set of optimal solutions, equally valid, for the realization of stratigraphies of the different types of external masonry; It will then be the task of the designer to choose among possible solutions which he believes to be most appropriate, based on the requirements of the project, which may be in terms of quality, cost, time or a combination of two or more of these evaluation parameters. It will thus illustrate how different solutions provided by the program can be used and collected in a three-dimensional graph.

Abstract:
Sweden’s real estate portfolio has a major renovation requirement. A large part of the renovations that need to be carried out are pipe replacement projects. These are major projects and not all housing associations are aware of the extent financial consequences it brings. Therefore, planning in the economy throughout the project are important. This thesis aims at seeing what affects a production estimate to differ from the actual final cost.ÅF infrastructure division thought that their calculations of the estimated cost for production too often differs to the actual final cost. At a first meeting with ÅF, it appeared that there has been discussion and thought for solutions to the problem for some time. The thesis is based on 3 issues that will provide answers on how to make a better production estimate.In order to answer the questions, project managers have been interviewed and literature has been studied. The assigned reference objects have been analyzed and compared in tables. This thesis has resulted in the insight of that the project managers at ÅF are relatively good at estimating the original cost of what the contractor produces for the pipe replacement projects. After the analysis, recommendations have been presented that can be developed and implemented in the ÅF approach to calculate their estimated cost of production even better. By calculating the costs that are not included in the original cost for the contractors in a more methodical manner, based on experience, the production cost can be optimized.The work has been going on for a limited time with delimitations and a selection of projects. The results presented in the report should be applied with caution and awareness about the differences in the projects.

M.Tech. (Construction Management)
The construction industry is a key sector in the development and economic growth of South Africa. However, the industry has not escaped the challenges facing other countries worldwide in terms of delivering construction projects within budget and on time as stipulated in the contracts. This study assesses the causes, effects and measures of minimising construction projects cost and schedule overruns in the Gauteng Province of South Africa. The data used in this study were derived from both primary and secondary sources. The secondary data was collected via detailed review of related literature. The primary data was collected through a questionnaire which was distributed to construction professionals. Out of the 200 questionnaires sent out, 146 were received representing a 73% response rate. Findings revealed that inadequate planning, change in project design, poor project management, inadequate financial provision and inaccurate estimates were the major causes of construction projects cost overruns. Furthermore the study also showed that the causes of construction projects schedule overruns in Gauteng province included: slowness in decision making process, reworks due to errors during construction, delays in approving major changes in the scope of work, delay in material delivery, shortage of skilled equipment operators and low productivity level of workers. Additionally, it was observed that construction project delays, increased project cost due to extension of time, liability of companies to bad debt and project abandonment. The study also revealed that extension of time, cost overruns, loss of profit, disputes and poor quality of work due to hurrying the project were the major effects of construction projects schedule overruns. Likewise, the study revealed that adequate planning, proper pre-contract planning, proper project implementation and management and good workmanship were the most effective ways of minimising construction projects cost overruns. Finally the results revealed that proper project planning and scheduling, effective strategic planning, site management and supervision, frequent coordination between the construction team, availability of clear information and communication channels were the most effective ways of minimising construction projects schedule overruns in the Gauteng Province of South Africa. It is recommended that all members of construction teams be trained and educated of the factors that cause project cost and schedule overruns in order to minimise these overruns.

abstract: This thesis presents a literature research analyzing the cost overrun of the construction industry worldwide, exploring documented causes for cost overrun, and documented parties responsible for the inefficiency. The analysis looks at a comparison between the metrics of construction projects in different continents and regions. Multiple publication databases were used to look into over 300 papers. It is shown that although construction demands are increasing, cost overrun on these projects is not decreasing at the same rate around the world. This thesis also presents a possible solution to improve cost overrun in the construction industry, through the use of the Best Value Performance Information Procurement System (BV PIPS). This is a system that has been utilized in various countries around the world, and has documented evidence that it may be able to alleviate the overrun occurring in the construction industry.

BIM has been applied to many bridge construction projects. Although BIM is used in bridge construction for analyzing and simulating the construction process. The information exchanges between stakeholders are still inefficient and insufficient due to poorly defined relationships between BIM model and the information required by stakeholders.Therefore, it is important to develop a platform of information exchanges for stakeholders according to their uses and objectives. This research focuses on the cost-related issues of the bridge construction with BIM model. First information requirements are analyzed according to the concept of building project hierarchy (BPH).The BPH, combines BIM model and the construction methods of bridge’s superstructure as a hierarchy of database. Then, each BIM component and its related work items are defined by the result of the above analysis to build the database of bridge components. Finally, IDEF0 is used to determine the required processes and information exchanges based on the bridge components database for managing projects costs. According to the case study, the bridge components developed can efficiently produce the budget for BIM-based projects. Key words: BIM, Information integration, Cost management, Bridge Constrction

Earned Value management ( EVM ) is a kind of performance measurement system which integrates time and cost. It expresses the achieved of capable achievement by the satisfied work package which is accomplished. Therefore it is an instrument for integrating time, cost and behavior. In America, Australia, Canada, Sweden, England, and Japan, it was used maturely and regards as the best practice of project management. EVM provides three measurement values: planned value, actual value and actual cost of project. These measurement values can help project manager to realize the present condition and provide a conformable measurement value. It can make effective control during the project afoot. This study used EVM, five processes of project construction management, adduced and established cost controlling of project construction management. To make a assessment for benchmark of project’s results and estimate the art of accomplishable efficiency. By using case study to treat the feasibility and meaning of practicing EVM to control project construction management. Per the combination of EVM and statistical control graphs, we can erect achievements audit and evaluate the index’s upper and lower limit. By this way, we can control whole project, to realize the targets: Faster, Better, and Cheaper. Eventually, adopted case study to test above-mentioned, the results are as follow. First, make effective standards performance evaluation and execute efficiency predominate project construction management is successful or fail. Second, combined the index of time, cost, and performance, EVM is the best method. Third, EVM provided crystalline and correct information of project, can predict the effectiveness. Fourth, makes statistics control diagram of project performance for controlling the project, is good for promoting effectiveness of executing project.

Abstract:
Optimization of time and cost in construction projects has been subject to extensive research since the development of the Critical Path Method (CPM). Many researchers have investigated various versions of the well-known Time-Cost Trade-off (TCT) problem including linear, convex, concave, and also the discrete (DTCT) version. Traditional methods in the literature for optimizing time and cost of construction projects range from mathematical methods to evolutionary-based ones, such as genetic algorithms, particle swarm, ant-colony, and leap frog optimization. However, none of the existing research studies has dealt with the optimization of large-scale projects in which any small saving would be significant. Traditional approaches have all been applied to projects of less than 100 activities which are far less than what exists in real-world construction projects. The objective of this study is to utilize recent developments in computation technology and novel optimization techniques such as Constraint Programming (CP) to improve the current limitations in solving large-scale DTCT problems. Throughout the first part of this research, an Excel-based TCT model has been developed to investigate the performance of traditional optimization methods, such as mathematical programming and genetic algorithms, for solving large TCT problems. The result of several experimentations confirms the inefficiency of traditional methods for optimizing large TCT problems. Subsequently, a TCT model has been developed using Optimization Programming Language (OPL) to implement the Constraint Programming (CP) technique. CP Optimizer of IBM ILOG Optimization Studio has been used to solve the model and to successfully optimize several projects ranging from a small project of 18 activities to very large projects consisting of more than 10,000 activities. Constraint programming proved to be very efficient in solving large-scale TCT problems, generating substantially better results in terms of solution quality and processing speed. While traditional optimization methods have been used to optimize projects consisting of less than one hundred activities, constraint programming demonstrated its capability of solving TCT problems comprising of thousands of activities. As such, the developed model represents a significant improvement in optimization of time and cost of large-scale construction projects and can greatly enhance the level of planning and control in such projects.

Scope, time and cost are the three key points that project management revolves around. These key points compose the “triple constraints” of a project. Regardless of the contract type, the core objective of project management is to facilitate the successful completion of projects within the triple constraints. For a contracted construction project, the triple constraints are absolutely crucial due to the restriction from the contract other than the unique construction environment itself. As a result, many invisible risks are embedded inside a construction project that must be carefully dealt with. Earned Value Management (EVM) has been generally recognized as an effective methodology for integrating the management of above mentioned triple constraints. This research studies the practice for implementing EVM to a construction project for its cost and schedule control from a contractor’s point of view. This thesis is mainly organized into three parts, EVM lead-in procedure, case-study, and the problems on applying EVM and suggestions for solution. It is expected that the outcome of this research may facilitate the development of a realistic EVM System (EVMS), and hence to mitigate the project risk and promote the project performance. For combining the theory with practice, this research considers the real construction environment and refers to ANSI/EIA-748-A Standard for EVMS and the prevailing global project management standards during the EVM lead-in procedure. On the case-study of EVM application, except for verifying the reasonability of the EVM lead-in procedure by real case, this research also studies the management meaning of various performance indexes resulted from the EVMS and the relations among these indexes. The research results will be provided as a feedback for future projects. Finally, this research classify and study some distortion problems encountered while implementing EVM under some different project management models and contractual environments .The research also makes suggestions for adjustment on the problems in order that the project will perform the EVM more accurately and more effectively, and then enhance the visibility on management.

Most of professional construction management (PCM) service providers, including engineering consultant, architects, and engineers firms, encounter that their service incomes are less than actual expenditures, but they cannot propose reasonable service fees in advance. Therefore, the common used payment methods for PCM service, the percentage of construction expense method and the lump sum method, encounter many implementation problems. This study analyzed and discussed on the cases of PCM service for public building construction projects, in which the percentage of construction expense method and the lump sum method are employed in service contracts. This study used the Cost-Plus-Fixed Fee (CPFF) payment method and information collected from real cases to simulate possible incomes and outcomes, and then discussed the problems existed in current payment methods. Based on the analysis and simulation on cases, this study concluded that the CPFF method is a suitable method to reflect service provider’s actual cost expenditures. Furthermore, this study proposed some corresponding actions for implementing the CPFF method. Research results would be valuable for reference while using the CPFF method in the future.

Abstract:

The residential building sector is one of the most energy intensive sectors in today’s civilization. With population growth and a rise in number of homeowners the effect is bound to worsen. A wave of green and sustainable strategies is on the rise hoping to moderate some of the negative effect on the environment. From embracing renewable sources of energy as an alternative to fossil fuels, to improving existing home systems to become more efficient, the construction industry is evolving into becoming more energy conscious. One of the biggest obstacles to this wave is a lack of awareness and a fear of initial costs among contractors, homeowners and clients alike. This research will use Life Cycle Cost Analysis on a varying combination of residential energy systems and the researcher hopes to establish the trade-off between initial investment and long-term benefits. The case being considered is a residence located in Indiana, US. Using past and current utility bills and energy simulation data of different energy consuming systems in the residence over its lifetime, economic models are generated. This research establishes that a combination of passive and active energy conservation measures results in the lowest life cycle cost. The study will be beneficial for further research and as a framework for residential life cycle cost analysis.
