Lean production is a systemic approach to meeting customer expectations, whatever they value, by reducing waste. At first glance, lean then could only contribute to sustainability, while sustainability is achieved only if the customer values sustainability. The paper has two objectives. One is to examine whether sustainability is feasible using lean production with sustainability as an added value. The second objective is to examine how current lean construction tools and methods impact the construction and operation of sustainable facilities. The authors also suggest how these lean construction tools and methods have evolved to contribute to green construction. For this study, the authors interviewed lean adopters and conducted literature surveys on lean principles and methods, and its impacts on the economic, social and environmental sustainability.

Materials for modules and payments for your workers are some of the main expenses for the concrete structures with stiffness. In view of this, module construction is one of the essential factors if the project succeeds or not. Traditional module construction that is involved in those activities without adding values results in wastes. This study aimed at adopting a compact method to reduce waste in the module works. The compact module construction model is developed to achieve this goal. Andon of this model is made use of build a spot assurance system. Labours can be assisted immediately in case of any issues are raised. Besides Andon, module processes are introduced to the Kanban system to decrease mold stock and fulfil the flow of process behind ceaseless work. There was one real case discussed to verify if the proposed module applies to all. Application findings indicate that the developed method is able to conduct mandatory banishment in the module flow of the process and add value in the operation.

The Lean Construction philosophy emerged to assist overcome the challenges in optimizing the productive processes of companies. As an effort to quantify the application degree of Lean philosophy in the civil construction companies, several measurement tools were created. In order to discuss the effectiveness of these tools into measuring the presence of the Lean philosophy in construction sites, the present study performed a critical analysis of its methodological procedures, based on four aspects: ‘questionnaires and forms’, ‘answering system’, ‘data collection methodology’, and ‘results’. Although it was not possible to investigate measuring tools from other countries, it was concluded that, among Brazilian methods, the one developed by Pereira (2012) is the most suitable for use since it presented just few problems in its formulation. This way, it is possible to do the intended measurement with assertiveness, substantially contributing to civil construction development.

There is a philosophy in the construction industry to reduce the cost of a project by reducing construction waste and improving productivity. With lower expenses, lean construction emphasizes the cost of the project at a minimum cost. Globally, the philosophy has gained a wide range of popularity in the construction sector. The Lean Construction has helped practitioners with several tools and techniques to implement at different stages of a construction project. Following global trends, this study has investigated lean practices in Pakistan. With the potential advantages experienced by its implementation in Pakistan's construction projects and the level of implementation of various types of tools and techniques has been analyzed. To achieve the goal, the study had tried to capture construction projects in which four shareholders are being represented, which are clients, consultants, contractors and material suppliers. Overall 34 completed questionnaires were collected and then analyzed. The results of the analysis have indicated that pull approach, standard of work, time consuming, visualization tools, the integrated project delivery methods and the quality failure in safe limits are common lean techniques which are being implemented to the local construction industry. While there are major benefits of waste reduction, client satisfaction, better communication, visual control and proper task management to build appropriate work are the key benefits of lean construction.

Abstract The construction industry is plagued by poor project performance and the adoption of lean construction is seen as a way to address this issue. Therefore, this research aims to assess the implementation of lean construction and its relationships with project performance in the Australian construction industry. Just in time, last planner system, Six Sigma, and 5S management are the four lean construction tools investigated in the research. Data were collected using a questionnaire survey from construction practitioners in Sydney, Australia. Results show that the implementation of these four tools is adequate, although some lean activities need to be implemented at a higher level. Lean construction also has strong correlations with many project performance indicators, demonstrating its value to the construction industry that is in a dire need of improvement. Finally, this research also recommends specific areas for improvements.

The Kingdom of Saudi Arabia (KSA) has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made. In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD) is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

The objective of this article is to improve building productivity, evolving from traditional construction to industrial construction. The methodology used here consists of analysing the use of materials, the construction design, the design of the spatial distribution programme, the use of auxiliary means and resources and the application of lean tools in construction. The results achieved here include a complete building system that integrates the design, project and execution, wherein the construction process is improved and inconsistencies in the final project are reduced. With the application of an industrial manufacturing methodology, the productivity in construction is improved, reducing costs, materials, execution times and waste. These productivity improvements result in construction being more sustainable. As a conclusion of the previous analysis, the elements that must be integrated into a complete building project and the need to incorporate industrial manufacturing into construction processes in order to achieve sustainable architecture are established.

Full textAbstract:
The profitability of most construction projects critically depends on construction productivity, which can lead to project cost overruns and schedule delays if not fully addressed. Although a literature review provides numerous worldwide examples of construction productivity improvement by mitigating and eliminating influencing disruptions through lean tool implementation, those studies considered a limited number of productivity disruptions in which the choice of lean tools was not clearly justified. This gap has significantly hampered the required improvements in construction productivity due to the limitations in selecting optimal solutions to fully overcome relevant disruptions and prevent their consequences. Hence, as a response to the aforementioned shortcomings, the present study develops the lean-Clancy-based decision-making matrix (LCDMM) that combines two different methods—the “Clancey heuristic model” and “lean construction”—with the goal of determining optimal and beneficial solutions to eliminate disruptions. The main thrust towards the adaptation of the matrix is based on its potential to link disruptions with solutions based on lean tools. In order to assess the practicality of LCDMM, the proposed solutions for two disruptions, as examples, are compared to existing practical solutions. Ultimately, it is clear that LCDMM, as a reusable tool, can assist scholars and practitioners in assembling the analysis of disruption waste and in selecting solutions for productivity improvement.

Abstract: Since the 1940’s, lean production principles have evolved and were successfully implemented by Toyota Motor Company. Lean construction is a production and management-based approach to a project. An increasing number of construction academics and professionals are storming the ramparts of conventional construction management in an attempt to deliver better value to owners while making real profits. As a result, lean-based tools have emerged and are successfully applied to simple and sophisticated construction projects. Generally, lean construction projects are easier to manage, safer, completed sooner, cost less and are of higher quality. Thanks to the success of the lean production system in manufacturing the construction industry has adapted lean techniques to eliminate waste and increase profit. It is a way to design production system to minimize the wastage of material, time, and effort in order to generate the maximum possible amount of value. The main objective of this study is to analyze and implement the lean construction practices. Keywords: lean construction, economic, safe, construction management

Abstract The construction industry is one of the most important industries for social and economic growth, as well as a source of wealth. Unfortunately, the construction industry has considerable costs, time, and quality issues, necessitating being resolved. This problem also happened in the Malaysian construction industry, mostly to meet the demands of infrastructure projects. Furthermore, over-processing refers to extra work done during the construction process that increases the likelihood of a project failing. This over-processing is caused by the consultant teams’ slow response time when a problem develops, as well as the site’s poor management system implementation. Lean construction (LC) is the alternative in resolving this non- physical construction wastes. LC is a constant enhancement to the construction processes in sustaining the organisation’s growth and profitability. This research aims to develop an LC tools framework that beneficial to future LC practitioners. This paper seeks to identify the most generated over-processing construction waste and the most LC tools to reduce over-processing construction waste on the site. This research uses a quantitative method approach, and the questionnaire survey has been sent to 310 G7 contractors registered with the Construction Industry Development Board Malaysia (CIDB) in Malaysia. A total of 116 questionnaires were returned, with a response rate of 37.4%. The findings revealed that the long approval process was the source of the majority of the site’s over-processing construction waste. Hence, management contracts, standard forms, total quality management, concurrent engineering and teamwork were the five most implemented LC tools by the LC practitioners in reducing over-processing waste. It is hoped that the outcomes of this research, able to help the LC practitioners deliver their projects. Thus, it would develop the future’s construction productivity towards a better quality of life.

The construction sector is lagging behind other industries in terms of efficiency and value achievement. Several building sector initiatives are introduced to improve productivity and project value enhancement. Significant developments such as Lean principles and BIM tools have been applied in the construction sector to achieve efficiency and enhanced productivity while minimizing waste. Lean principles in construction practice are a developing research area, and BIM tools have been widely used in construction project delivery and communications. Although these concepts are beneficial, barriers to their integration and joint implementation have not previously been explored. The paper investigates barriers to implementing Lean and BIM and their interrelationships in the New Zealand construction industry. A three-step triangulation methodology was used in the study to validate the findings. The study used an extensive literature review process, case studies, and expert interviews to consolidate the findings. Barriers to Lean and BIM implementation in construction practice were identified, which include strong cultural resistance, lack of Lean-BIM understanding, resistance to change, lack of knowledge of the Lean-BIM method, and lack of support from senior staff in New Zealand organizations. The effect of implementing Lean-BIM principles is discussed, as are recommendations for implementing the method in construction practice.

Abstract: Lean manufacturing and lean construction have the same goals according to Paez et al. (2005): elimination of waste, cycle time reduction, and variability reduction. One of the ways of reaching the goals of lean construction is flow according to Paez et al. (2005). When trying to attain flow in construction one need to realize that there are differences between manufacturing and construction, which may make it difficult to attain the same flow between different processes, attained within manufacturing (Koskela, 1992). These differences are certain construction peculiarities such as one-of-a-kind projects, site production, temporary organization and regulatory intervention, aspects more common with construction projects than manufacturing. According to Koskela (1992) however, the same production principles apply and there is room for improvement when it comes to flow in the construction industry. By using lean thinking and lean tools and adapting them to the construction industry this master's thesis purpose is to develop a tool to identify and measure waste, guide in which order waste should be reduced and by this enabling estimations of potential consequences that might occur by implementing a lean approach at a construction site. This is of interest in order to bridge the research gap between conceptual lean construction and research based on empirical studies

The shortage of constructive philosophies, principles, techniques, and tools in construction project delivery and sustainability before the 1990s, together with the abundance of them after 2000, creates two different eras which are of prime importance. The former one’s considerable advantage was a common understanding and set of practices (e.g., the critical path method for scheduling), which seems to be a goal to achieve in the later one. In this regard, the combination and integration of best practices, tools, and techniques in construction project delivery can be considerably helpful for benefiting from their advantages and covering their limitations. Thus, this study aims to develop a conceptual framework for lean and sustainable project delivery in building construction projects. To do so, a systematic literature review was carried out, through which 230 studies were located and analyzed via thematic analysis to realize the purpose of this study. The findings present a conceptual framework for project delivery which combines and integrates sustainability, lean construction, and building information modeling in terms of principles, practices, tools, and techniques. Practically, this study’s results inform practitioners in the construction industry on the lean and sustainable delivery of building construction projects.

Lean aims to maximize value while minimizing waste. Lean practices are likely to reduce the number potential hazards and errors. The use of Lean practices in construction is essential to experience less hazards. Benefitting from Lean practices has gained much attention in the last decade. Especially, the destroying effect of hazards and accidents is of utmost importance in terms of seeking for better strategies. Within this context, Lean practices offer a wide variety of advantages and provide means for achieving greater success in projects. This study investigates the use of Lean practices in post disaster management. Since post disaster management includes the activities to help community in rebuilding, Lean tools and techniques might be employed to better handle post disaster management processes. The study also scrutinizes the integration of Lean practices with the post disaster processes and encourages the community to compete against the destroying effect of disasters thanks to using Lean tools and techniques. The main contribution of this study is that it introduces Lean practices to be used in the post disaster management processes, which might potentially remove safety concerns in construction sites up to a great extent.

The lean construction concept has been introduced successfully into the construction industry to reduce construction wastes. While lean concepts require a rethinking of existing construction processes and practices, there is also a need for new tools to implement lean thinking. In addition, while lean can improve project time and cost performance, it may also have an impact on sustainability, which mainly focuses on reducing environmental impact of construction. This paper describes the implementation of lean construction and its implication on environmental sustainability from a contractor perspective through a case study. The study observed waste in both project-level contractor coordination and operation-level construction performance. A vertically-integrated scheduling system that features location-based look-ahead scheduling and graphic weekly work planning was developed to improve project-level contractor coordination. To implement waste elimination solutions at the operation level, construction simulation and 3-D visualization were applied to facilitate lean implementation. Meanwhile, the impact of lean on sustainability were observed and discussed.

Purpose – The contribution of lean construction techniques in sustainable construction cannot be over emphasised, as sustainable development is now enshrined in government policy. In addition, lean construction is now faced with the challenges of sustainable development, continuous improvement, waste elimination, a stronger user focus, increased value for money along with high quality management of projects and supply chains, and improved communications. This paper presents an exploratory study from extant literature and the results of the use of questionnaire survey among construction participants to explore the contribution of implementing lean construction techniques in sustainable construction. Design/methodology/approach – Surveys of UK-based construction professional were conducted. The data collected were analysed with SPSS 19.0 version software using the percentile method, Cronbach ' s α reliability test, Kruskal Wallis test, Kendall ' s coefficient of concordance and one sample t-test. Findings – Results from this study indicate that there are several benefits associated with implementation of lean construction and sustainable construction. The overall perspective of professionals within the construction industry, according to questionnaire survey, shows that benefits such as improved corporate image and sustainable competitive advantage, improved process flow and productivity, improvement in environmental quality and increased compliance with customer ' s expectations are realised following integration of principles of lean construction and sustainable construction within construction industry. Just-in-time, visualisation tool, value analysis, daily huddle meetings and value stream mapping are the most common lean tools/techniques for enabling sustainability. This study also identified several areas of linkage between lean and sustainability such as waste reduction, environmental management, value maximisation, and health and safety improvement among others. Originality/value – The originality of this paper lies in its consideration of lean construction principles to better understand its impact on sustainable construction. This research contributes to the awareness of the benefits that can be derived from the implementation of lean construction in sustainable construction within the construction industry.

Full textAbstract:
The construction industry is often ranked top in producing the largest amount of waste during a project, be it the waste of material resources or the waste of manpower. This has elevated the need for an improved and more structured management technique. This study will look into the principles and practices of lean management pertinent to highway construction projects to analyze whether lean management practices can improve the management efficiency for complex projects. This study adopted a quantitative approach, and a linear regression model has been used to investigate correlations between the lean test factors and the efficiency-dependent variables. It was found that lean management tools that are used repeatedly and the ones that require a high level of detailing are positively associated with efficiency improvement in highway construction projects. In particular, LPS, JIT, and VM were found to be more commonly used in highway construction projects. The research results will aid in the initial decision-making process of the project managers, as they will be able to map different lean tools with their benefits and limitations and then select the one that best suits the project needs and deliverables. Future studies can adopt the interpretivism paradigm to explore new theories and concepts related to highway construction management.

Full textAbstract:
Like many other countries, the presence of wasteful activities is very common in Kazakhstan’s construction industry. This severely affects the productivity of construction processes. Lean methodology maximizes the value of a process by minimizing wasteful or non-value adding (NVA) activities. This study aims to explore and quantify the impact NVA items on construction productivity. Several observations were made for construction processes in Astana, Kazakhstan to investigate and quantify various types of wasteful activities. Moreover, a survey was conducted to examine the general understanding of wasteful activities and Lean methods within the construction industry in Kazakhstan. In terms of wasteful activities, a similarity was found between the observed construction processes and survey results. Furthermore, apart from the commonly found seven types of wasteful activities, some other sources of waste, such as “preparation” and “break”, were found from the observations. Finally, wasteful activities were mapped with commonly used Lean tools, as found in the literature, so that productivity can be improved by minimizing NVA activities. From the mapping and the survey results, value stream mapping (VSM) was found to be the most effective Lean tool, since it facilitates increased visualization.

Purpose The purpose of this paper is to explore the applicability of lean construction (LC) concepts and tools in necessary, but non-value-added activities (NVAA) in small and medium-sized enterprises (SME). The application of the lean tools in this way facilitates the flow of information and handling material, improving productivity, quality and performance. Finally, practical results motivate a discussion on the real potential of LC principles and on the challenges related to its implementation. Design/methodology/approach The methodology makes use of direct involvement in the environment under study. Some of the activities performed were the value stream mapping and time and motion studies of the company’s process selected, identification of wastes and the proposition of improvements to be implemented. Findings The main findings are related to the benefits of the application of LC not only in value-added activities but in activities that can influence the development and workforce planning, especially for SME businesses. This company should be able to achieve better management decisions and results after implementing the LC principles, overcoming the limited resources. Originality/value This proposed method helps in overcoming the lack of systematic procedures, enabling LC in activities that not add value properly. It has the advantage of integrating existing tools and models effectively, which not only improve the shortcomings of the conventional methods but also result in more convenient calculation and application.

Purpose This paper aims to investigate the application of lean construction (LC) techniques in reducing accidents in construction projects. Design/methodology/approach A quantitative approach was used to collect the required data using a questionnaire survey and descriptive analysis was used to analyse the collected data. The LC techniques that were investigated in this paper are related to the tools of the last planner system (LPS), increased visualisation (IV), 5S, error-proofing, daily huddle meetings (DHMs), first-run studies (FRS), continuous improvement (Kaizen) and accident investigation (5Whys). Findings The overall results indicated that LC techniques are poorly implemented in construction projects in the Gaza Strip. The top three LC tools used to reduce the causes of accidents in the Gaza construction projects were 5Whys, 5S and LPS, while the highest three LC techniques applied to reduce the causes of accidents that were applicable were cleaning the workplace and removing materials and machines that are not required; conducting accident investigation and root cause analysis programmes; and using safety signs and labels on site. Research limitations/implications There is a lack of information and published studies regarding the links between LC and safety, especially in the Middle East. This paper is limited to the perceptions and geographical boundaries; therefore, it cannot be generalised. However, it could form the basis for useful comparison in the future. Triangulation research method could also be used in future research to minimise the bias and validate the conclusions. Practical implications The findings of this paper will stress professionals and construction companies in Gaza to reconsider their behaviour towards using LC techniques. The findings of this paper will aid them to shift their attention and resources towards including LC techniques in their plans to reduce the causes of accidents on construction sites. Social implications The findings of this paper will encourage professionals and construction companies in Gaza to reconsider their behaviour towards using LC techniques. The findings will also aid them to shift their attention and resources towards including LC techniques in their plans to reduce and/or avoid the causes of accidents on construction. Originality/value Because of the lack of published works that are specific to the Middle East, the authors believe that the originality lies in the paper’s serious attempt to explore the application level of the LC concept to safety in this part of the world. This paper contributes to a better understanding of the applicability of LC techniques in terms of accidents reduction. Findings from this paper provide a clear picture of the current status of using LC techniques to reduce accidents in the Gazan construction projects which drive them to investigate the main barriers and try to overcome them.

Full textAbstract:
Lean construction has been viewed as an effective management approach for reducing the occurrence of no-value or destructive activities, such as wasting resources and safety-related accidents. However, few studies have systematically addressed how and to what extent lean construction practices influence construction safety. To bridge this gap, a conceptual model is developed and validated using a system dynamics approach. The construction system in this model comprises four sub-systems (i.e., environment system, equipment system, management system, and employee system). Data were collected from 448 projects in China. Simulations were conducted to determine the correlations between five types of lean tools and the four construction sub-systems. The results show that: (a) 5S management has significant positive impacts on the control of key locations and facilities at construction sites, and contributes to the mitigation of environmental impacts; (b) visual management can significantly improve safety compliance and safety management; (c) just-in-time management has significantly positive influences on the safety facilities layout and formulation of the safety plan; and (d) the Last Planner® System and conference management are effective in improving safety training and the implementation of the safety plan. These findings provide new insights into the use of lean construction for improving construction safety through the implementation of a targeted lean approach.

Full textAbstract:
The competitiveness in the construction industry is leading companies to implement the Lean philosophy to improve project management and prepare to begin the adoption of Construction 4.0. However, this implementation generates several barriers, depending on the type of company and the country where it is implemented. For this reason, the following research aims to identify the barriers generated in implementing the Lean philosophy in Peru and SMEs. The following study began with a literature review, followed by a questionnaire, which six Lean experts evaluated. Then, 127 Peruvian professionals answered the survey, and the data were analyzed with RII and Exploratory Factor Analysis. As a result, the barriers to Lean Construction were grouped into four groups to analyze their impact on the industry: collaboration, education and implementation, organizational vision and system; Lean theory and philosophy; and Lean tools, coordination, and information flow. Barriers were also analyzed by project type, stage, and organization size to conclude that implementation barriers are directly related to company size. Finally, the obtained barriers are discussed, and Construction 4.0 is proposed to reduce their impact on construction projects. These results can be helpful for implementers to plan strategies, improve knowledge about Lean Construction implementation, and adopt new techniques that could help improve the construction industry’s productivity.

Construction sites are plagued with numerous problems, such as improper planning and management, high amounts of waste generation and low awareness of waste reduction. Construction and demolition waste literature provides several best practises and prescriptive strategies that help minimise waste during construction. However, it lacks in the systematic identification and minimisation approach of all possibilities of waste. Therefore, studies focusing on principles and tools that help systematically analyse the inefficiencies of on-site processes leading to waste generation and philosophies addressing waste minimisation are necessary. As eliminating waste is one of the key lean principles, this article discusses the need and importance of integrating the lean construction with the construction and demolition waste management. This article aims to estimate and assess the causes of waste generation in a high-rise building construction through a case study in Chennai city (India) using value stream mapping, a key lean construction tool. Onsite monitoring and measurement were performed to quantify the amount of waste generated. A waste generation rate of 66.26 kg m−2 was identified, of which concrete, cement mortar and brick waste represented almost 90% of the total construction waste. Direct observation and interviews of site personnel were conducted to understand the causes of waste generation. A strategic framework has been proposed to improve construction and demolition waste minimisation depicting the synergy of combining lean construction principles with construction and demolition waste management strategies. The proposed framework helps in the systematic identification, assessment and minimisation of on-site construction waste generation.

The advent of Construction 4.0 has played a major role in construction industry development through the improvement of quality performance. One of the parameters that have contributed immensely to the management of construction quality in the industrial revolution era is Industry 4.0, the Internet of Things (IoT), and Lean thinking concepts. Lean construction is characterized by a set of clear objectives in project delivery involving the concurrent design of products and processes. The study aims to carry out an exploratory study of the application of Construction 4.0 and Industrial 4.0 in quality management of building works and the development of Lean-based quality management models: The study engaged a survey design approach, and a random sampling technique was used to select the study samples. A structured questionnaire designed on a Likert scale 1–5 was used to collate data on the quality aspect of a construction project, and the data were used in model creation. The parameters that emerged are cast as the quality management model. The resultant factors were categorized into three (3) quality categories, which are the Zero level Defect range, Medium Quality, and High-Level Quality Range. The three (3) quality factors were recommended for adoption for quality management of residential building projects.

Purpose In recent years, innovative methodologies of product development such as lean product development (LPD) and agile project management (APM) have emerged. Even though previous research studies focused on these subjects, only few of them were focused on traditional industries, as civil construction. The purpose of this paper is to cover a part of this gap by estimating the potential of the application of these two new approaches (LPD and APM) in the construction industry, more specifically on the design stage. Design/methodology/approach For this, a case study has been conducted in order to understand if some of LPD and APM tools and practices had already been used, and also to evaluate the potential application of these new methodologies. Three Brazilian companies have been evaluated, all of them were exclusive executors of the design stage and presented distinct characteristics (size, structure, business model, etc.). Findings The results show that there is currently little adherence to LPD and APM practices within the companies studied. In terms of potential application of these new methodologies, the study has identified evidence regarding technical similarities between the reported cases and others mentioned in literature. However, the interviewees’ reception of these concepts was mostly pessimistic, showing considerable resistance to changes in the current process. Originality/value According to the analysis, the study identified that the main challenge/hampering to the implementation of these tools in the cases studied herein are the functional organizational structures, the customer–supplier relationships and the internal cultural resistance to change.

The growing context of globalization permanently increases pressure on the construction companies to improve their performances in order to resist to the constraints of competitiveness in the international market. It has become ineluctable to look for introducing a new alternative capable of bringing creative improvement to the traditional production system. This paper will relate mainly to the most relevant management techniques in the construction industry, and more specifically, the lean construction concept. Initially, we will determine the main characteristics of the construction industry compared to the manufacturing industry according to three levels: on-site production, one of a kind projects, and complexity. Subsequently, we will focus our attention on the main sources of waste in the construction industry. Finally, a rigorous comparative study will be carried out to show the contribution of the lean construction tools in the promotion of traditional construction especially at the level of the following factors: Creating value and eliminating waste; Planning and mutual coordination; Site organization. Lean construction as Last Planner System (LPS), Value Stream Mapping (VSM), Just-in-Time philosophy, Visual management (VM) and 5S have shown a great ability to improve the traditional production system through waste reduction, encouraging people involvement, ensuring a pull flow production, and promotion of a continuous improvement philosophy.

Abstract Covid-19 pandemic has originated that a great number of countries’ governments demand universities to teach online classes, presenting a challenge to redesign the courses that had construction site visits included in the curricula. The purpose of this work is to present the successful strategies employed on the teaching of building construction, applied in a third-year civil engineering program of the Pontifical Catholic University of Peru. The methodology was designed so that one can adapt the pandemic and post-pandemic stages proposing a balanced use of virtual platforms and software for video conferences and laboratories, incorporating tools like Building Information Modeling, Lean construction, among other systems. Given the sanitary emergency, the construction site visits were replaced by virtual visits to construction projects generated with scanner laser technology, photogrammetry, and BIM, generating digital twins that were stored in online platforms. Students toured the construction project virtually and in an interactive manner, and along with the description of the professionals in charge of the project they were able to reach a good level of comprehension of the organization and the construction processes. In addition, students developed the layout plans of the temporary works with BIM models. On the other hand, the course taught to generate and analyze the unit prices and quantity surveying of activities using the BIM methodology with 5D software, developing the project budget. The success of this methodology is shown through the notable quality of papers and evaluations taken, through the results of surveys taken on students--which had an effectiveness rate of 96.4 % --, and on the improvement opportunities determined. This paper presents tools relevant that may be adapted by the academia and practitioners related to building constructions, for virtual or face-to-face learning.

Recently, a significant number of scientists' works have been devoted to the application of the lean-production principles, in particular, the introduction of lean construction. Objective construction cost estimation is a key factor in construction projects. The article discusses the problems, significant losses, low productivity in construction companies and the possibilities of their elimination due to the use of the lean-construction management concept as an innovative approach in modeling the structure of the standard time determining for construction processes implementation in order to increase the company's competitiveness. The productivity of the construction industry worldwide has been falling for the past 40 years. Companies must use appropriate methods to reduce their losses and increase productivity levels so that they can stand in the rapidly changing competitive environment of the current business environment. One of the approaches to improving the situation is the use of "lean management" in the construction industry is the result of the desire of construction business owners to optimize costs and increase labor productivity, the efficiency of organizational and technological processes, and introduce lean- production in the construction industry. A huge number of scientists and construction professionals are trying to change the traditional organizational and technological form of construction production and add value to owners, while making real profits. As a result, lean manufacturing tools have emerged that have been successfully applied to simple and complex construction projects. Ukraine is very far behind in terms of the development level of innovative processes from many countries of the world. Outdated ENiR norms, which were developed without taking into account the Lean strategy, need to be finalized. Of course, the introduction of a lean manufacturing system is a topic for the near future. Thanks to this, it is possible to significantly reduce the cost overruns on projects, as well as the time of their implementation up to 30%, or even more. Therefore, future research objective should be the development of a new modern methodology for determining the standard time, which will take into account the criteria of lean technologies, as an innovative approach in modeling the structure and sequence of all operations of construction processes.

The construction industry is responsible for the infrastructural and physical development of nations and plays a pivotal role in determining economic equilibrium of nations of the world; hence, there is a need for constant evolving of advanced ways of carrying out construction operations. The concept has led to the evolution of Construction 4.0, which entails harmonizing disruption in technological applications to enhance construction productivity. The study, therefore, provides an attempt at evolving an enhanced approach to improve construction processes and resource management through application of lean construction and Industry 4.0. The purposive sampling method was used in this study to collect data. The data collection instrument consists of a structured questionnaire designed in a Likert scale of 1 to 5 distributed to 100 construction professionals through an online method that is actively involved in construction operations. The following parameters were censored and profiled, while the results are in tables and charts. The parameters include areas of lean thinking that could enhance Construction 4.0, areas of disruption in Industry 4.0 that influence Construction 4.0 advancement and parameters for practical integrating of lean thinking approach and Industry 4.0. Additionally, the influence of Industry 4.0 in technological development for the construction industry, disruptive innovation of Industry 4.0 and gains towards Construction 4.0. Furthermore, the relevance of Construction 4.0 in construction productivity, the importance of Construction 4.0, industrial application drivers in achieving Construction 4.0, future of Construction 4.0, achieving automation goal in construction and performance expectation of lean thinking and Industry 4.0 in the construction industry are found necessary. Simple percentage, Spearman rankings, Chi-square test, Student-T test, Mann–Whitney-U test and Relative Agreement and Importance index are the tools used to process the data. The study discovered, among others, the veracity of contingency approach in harnessing attributes of the lean thinking concept and disruptive applications in achieving Construction 4.0. The study recommends the application of the hybrid model suggested in the study as a guide to deployment of an application that could help in industrial productivity.

Full textAbstract:
Few construction companies apply the available lean tools and processes in an integrated manner when managing design. Additionally, lean design management tools and processes each have their own strengths and optimal phases in which they should be applied. Earlier approaches in lean design management have not explicitly included the level of detail of building information model (BIM) models in connection with planning methods. For example, the Last Planner System (LPS) uses collaborative social methods to obtain task dependencies and commitments from project stakeholders, but it does not provide any guidance regarding what those tasks should be in a BIM-based process. With regard to production, this guidance is provided by combining location-based methods, such as a location-based management system or takt planning, to LPS. In a similar manner, by combining information from various sources, this paper defines a location-based design management process using the concept of level of detail that can be integrated with LPS. The level of detail definition must be based on the requirements of the end-user in each stage of the construction project. The process was cocreated and validated in focus group meetings with design and construction companies and further evaluated and assessed by applying it in a case project.

Purpose – The purpose of this paper is to present a case study on the use of Lean Six Sigma principles and tools to study the improvement in design and construction services at a university. The quality of facilities services at universities has been criticized by users calling for improvement. Design/methodology/approach – Quality of facilities services at universities has been criticized by users calling for improvement. The purpose of this paper is to present a case study on using Lean Six Sigma principles and tools to study improving design and construction services at a university. Findings – It was found that non-value-added general improvement review form (GIRF) process steps involving revisions and rework for the design and construction result in time delays, cost increases and quality deficiencies and render cost estimates unreliable; these are unnecessary and should be minimized or eliminated. It was additionally noted that administrative reviews and approvals embedded in GIRF processes slow down work flow, leading to similar problems. Because such steps may be needed for institutional reasons precluding elimination, it was recommended that efforts be directed toward reducing their durations and costs. Overall, the Lean Six Sigma methodology proved to be successful for the intended purpose. Originality/value – Although universities are aware of their facilities services’ quality issues and have been addressing them, no published information is available on how to systematically evaluate and improve such services to increase customer satisfaction. This paper aims at filling this gap.

Full textAbstract:
With the evolution of Industry 4.0, some problems related to inefficient digitalization become clearer in organizations. To minimize these problems, implementation of the lean philosophy is needed in the digital environment. However, before Lean can start to solve the digitalization problems, there is a need to digitalize its tools so that they can comprehend the Industry 4.0 dynamics and become more effective. The aim of this study is to contribute to the theoretical development of Lean tools in the context of Industry 4.0, promoting directions for the industrial sector from the evolution, difficulties, benefits, implementation and trends of Lean 4.0 tools. To achieve this objective, this study performs a systematic literature review and content analysis of 53 papers from 35 journals. The main results of the research show: (i) the characterization of the Lean 4.0 tools; (ii) the evolution of the Lean tools after the integration with digital technologies; (iii) the main trends of Lean 4.0; (iv) the proposal of a Lean 4.0 theoretical framework. From these results, this paper seeks to promote insights for studies in the area of Lean 4.0, as well as for companies to implement and use the Lean 4.0 tools for better improvement in their digital processes and avoid the digital waste.

The present article’s main objective is to describe the synergies generated from the simultaneous application of the Last Planner System (LPS) and OHSAS 18001. We explain the main principles, tools, techniques and practices of the Lean Construction philosophy and LPS that integrate and make synergy with the elaboration of Safety and Health Study, the implementation of the Safety and Health Plan, and with the OHSAS 18001. The LPS elements are correlated with the OHSAS 18001 requirements: (1) Policy; (2) Planning; (3) Implementation and Operation; (4) Checking; and (5) Management Review. The methodology used to validate the proposal is based in a review of the published literature in the last years, in which information was quoted from the Conferences of the International Group for Lean Construction (IGLC), Lean Construction Journal, Lean Construction Institute, among others. This paper hopes to bring integration and collaborative work from the Production and the Safety and Health Department.ResumenEl presente artículo tiene como objetivo describir las sinergias generadas en la aplicación simultánea del Last Planner System (LPS) y la OHSAS 18001.

Full textAbstract:
This paper presents issues critical to the development and successful implementation of computer simulation models for ship component manufacturing within a naval shipyard environment. More specifically, it addresses the need for a supply chain approach to developing simulation models for use as a management tool. The problem domain is the naval shipbuilding industry, which is different from industries associated with traditional manufacturing. Due to the tremendous number of components associated with naval warship construction and the extreme length of the build cycle, managing such an enterprise presents a formidable challenge. As Northrop Grumman Newport News strives to be a lean enterprise, managers will need new tools to address the lean initiatives of the many shops and construction areas within their domain. In this paper, it is suggested that the application of computer simulation using a component supply chain approach could provide management with a powerful tool to improve efficiency. A three-phased approach for the development of an enterprise supply chain model is presented. In the first phase, individual simulation models are developed for manufacturing and material support functions. The second phase addresses the linking of the models into small model networks. In the third phase, additional models are developed and more sophisticated networking strategies are utilized.
