Construction Productivity In The Multilayer Subcontracting System

This book focuses on current subcontracting practices in the construction industry and their effects on Singapore’s construction productivity. It offers readers a better understanding of how the fragmentation of large and small firms in Singapore impacts construction productivity when operating under the commonly adopted multilayer subcontracting system (MLSS), which extends globally to the construction industries in other countries that have adopted the MLSS. The book also assesses the effectiveness of subcontracting practices in helping local contractors improve their construction productivity (and thereby improve the industry’s overall productivity). In closing, it provides recommendations on how the problems associated with the MLSS can best be addressed, and how its benefits can be capitalized on through organizational learning.

PRODUCTIVITY IN CONSTRUCTION PROJECTS From planning/design to post-construction, this valuable guide provides the construction industry the key to understanding the importance of properly tracking and measuring productivity, resulting in increased efficiency and profitability for contractors, subcontractors, owners, civil and construction engineers, and attorneys. Productivity in Construction Projects anticipates and answers the questions of owners, contractors, sub-contractors, and construction professionals to avoid cost overruns in a specific area of work, or when activities are taking more resources to perform than planned. Packed with real-world case studies, Productivity in Construction Projects' thirteen chapters move beyond the symptoms and provide a remedy. This book provides a comprehensive look at how to: Complete more projects on time and budget, and earn greater profits and future business. Track and analyze productivity on construction projects, and quantify additional costs resulting from productivity losses. Select the right experts and attorneys should litigation or arbitration occur, and employ credible and reliable methods of analysis. Solve problems on the project instead of incurring lengthy and costly litigation or arbitration.

First published in 1997, this volume joined the debate assessing the potential of the Just-In-Time management philosophy from the manufacturing industry for Singapore’s construction industry by examining the "off-site" prefabrication of precast concrete components in Singapore, in comparison with traditional management systems. In the wake of the 1991 Strategic Economic Plan of Singapore, which forecasted alarmingly low productivity in the local construction sector, the authors noted that construction in Japan was 35% more productive, whilst Finland was 75% better. Highlighting immense potential for the JIT approach, they explore the JIT philosophy, traditional systems, construction wastes and comparisons between construction and manufacturing.

This book focuses on the influence of socio-economic and land-use policies on the commuting problems and quality of life of the poor in Singapore and Hong Kong. It considers the influence of self-organisation: how the mobility of an individual is constituted by structures such as transport systems or socio-economic structural factors, as well as influenced by individual decisions. Where most transport studies focus on the influence of factors such as income inequality, the gender gap, and the built environment, this book fills a gap in paying particular attention to the influence of individual decisions on commuting. Given the prevalence of the former in research, government decision-makers are often constrained by these approaches and fail to understand the commuting problems of the poor. This book argues that the self-organisation approach provides some ideas that are outside the common conceptual framework in conventional transport planning and looks to improve mobility of lower-income commuters. Relevant to social science researchers working in areas such as urban planning and transport, mobility deprivation, and poverty, this book breaks new ground in quality of life studies in the Singapore and Hong Kong contexts.

Despite the size, complexity and importance of the construction industry, there has been little study to date which focuses on the challenge of drawing reliable conclusions from the available data. The accuracy of industry reports has an impact on government policy, the direction and outcomes of research and the practices of construction firms, so confusion in this area can have far reaching consequences. In response to this, Measuring Construction looks at fundamental economic theories and concepts with respect to the construction industry, and explains their merits and shortcomings, sometimes by looking at real life examples. Drawing on current research the contributors tackle: industry performance productivity measurement construction in national accounts comparing international construction costs and prices comparing international productivity The scope of the book is international, using data and publications from four continents, and tackling head on the difficulties arising from measuring construction. By addressing problems that arise everywhere from individual project documentation, right up to national industrial accounts, this much-needed book can have an impact at every level of the industry. It is essential reading for postgraduate construction students and researchers, students of industrial economics, construction economists and policy-makers.

This book introduces and develops the novel concept of Lean Construction 4.0. The capability of Lean Construction to effectively adapt the architecture-engineering-construction (AEC) industry to this new era of digital transformation requires a reconceptualization of the triad people-processes-technology as a foundation for the theoretical and practical framework of Lean Construction. Therefore, a shift towards Lean Construction 4.0 is required. Lean Construction 4.0 is a new systems-wide thinking approach where synergies and overlaps between Lean Construction and digital/smart technologies go far beyond BIM to reshape the way we design, manage, and operate capital projects in the modern age of automation. This pioneering new book brings together the views of world experts at the interface of Lean Construction and digital/smart technologies, in order to channel research efforts, to introduce and discuss current research and practice, challenges and drivers, and future perspectives of Lean Construction 4.0. It is not the aim of the book to keep adding digits to the term ‘Lean Construction’ to ‘catch up’ with the industry revolutions as they go on. Instead, after reading this book, it will be undeniable for readers that the triad process-people-technology as proposed by Lean Construction 4.0 is required to achieve an effective, long-lasting digital transformation of the AEC industry. Thus, the aim of Lean Construction 4.0 is better explained by what it evokes: a future vision of construction systems comprising people, processes, and technology using Industry 4.0/5.0 as a basis for technological innovation in the AEC industry coupled with Lean Construction theory and practice as a jettison for improved processes and systems integration. The Lean Construction 4.0 concept coined and developed in this edited book is unique and the chapters provide practitioners and academics with a provocative reflection on the theoretical and practical aspects that shape the Lean Construction 4.0 concept. More importantly, Lean Construction 4.0 proposes a rationale for the AEC industry not only to survive, but to thrive!

During the past several decades, the manufacturing and service industries significantly increased their levels of productivity, quality, and profitability through the application of process improvement techniques and information technology. Unfortunately, the construction industry lags far behind in the application of performance improvement and optimization techniques, as well as its overall competitiveness. Written by Lincoln H. Forbes and Syed M. Ahmed, both highly regarded for leadership and innovation, Modern Construction: Lean Project Delivery and Integrated Practices offers cutting-edge lean tools and other productive strategies for the management of people and processes in the construction industry. Drs. Forbes and Ahmed focus mainly on lean construction methodologies, such as The Last Planner(R) System, The Lean Project Delivery System (TM), and Integrated Project Delivery(TM). The tools and strategies offered draw on the success of the world-renowned Toyota Production System (TPS) adapted to the construction environment by construction professionals and researchers involved in developing and advocating lean construction methods. The book also discusses why true lean construction can best occur when all the construction stakeholders, owners, designers, constructors, and material suppliers are committed to the concept of optimizing the flow of activities holistically while de-emphasizing their self-interest. The authors also reintroduce process improvement approaches such as TQM and Six Sigma as a foundation for the adoption of lean methodologies, and demonstrate how these methods can improve projects in a so-called traditional environment. The book integrates these methods with emerging interest in "green construction" and the use of information technology and Building Information Modeling (BIM), while recognizing the human element in relation to motivation, safety, and environmental stresses. Written specifically for professionals in an industry that desperately needs to play catch up, the book delineates cutting-edge approaches with the benefit of successful cases and explains how their deployment can improve construction performance and competitiveness.

Master's Thesis from the year 2016 in the subject Engineering - Civil Engineering, University of Zambia, course: Master of Engineering Project Management, language: English, abstract: In recent years there have been a substantial number of projects conducted in the Zambian construction industry. Due to the magnitude and complexity of many of these projects, contractors have resorted to subcontracting to share responsibilities and mitigate project risks. The Zambian government has also invigorated the practice of subcontracting in the construction industry as it plays an important role in increasing economy viability and building capacity. Instead of improving project success, subcontracting can act as a catalyst for poor project outcomes. Though there are many reasons that contribute to problems from subcontracting, a poor relationship between main contractors and subcontractors can be seen as a notorious contributor affecting construction works. The study aimed at investigating the relationship between the main contractors and subcontractors in the Zambian construction industry and recommend a framework that can be implemented to better the relationship. The study also examined the effects of a poor interface between main contractors and subcontractors in Zambia. Data collection techniques used included literature review, interviews and questionnaire surveys. The relative importance index was used to determine the ranking of the results of the study. Using the results adduced from the study a main contractor-subcontractor non-contractual partnering model was developed. The study established that the relationship between main contractors and subcontractors in Zambia is poor therefore needing attention. Interface problems were caused by payment issues, poor communication, unexpected price escalations and poor construction work. In order to address interface problems, the study found that there was need for better communication between the parties, timely payments and subcontractors’ access to labour and machinery. However, the study, had some limitations that need consideration when interpreting the results found. The limitations included scarcity of specific literature on subcontracting in the Zambian construction industry, the size of the sample only being limited to Lusaka. Nevertheless, these limitations could be addressed through further studies.
