The lean construction frameworks have been developed for years to enhance the poor performance of Indonesian project delivery system which influenced by the waste of non-value adding activities. Never the less most of the developments were limited on working process and lack in people empowerment. Toyota Way which integrate working process optimization and people empowerment, was developed as a lean construction frame works. This paper aimed to assess the implementation of Toyota Way principles in project delivery system by observing project’s delivery current state (status quo). The assessment began by conducting a questionnaire survey about Toyota Way implementation which then validated by interview with involved stakeholders and field observation. The assessment showed that project’s stakeholders were still unfamiliar with Toyota Way concept. Although some Toyota Way guidelines have been used in projects completion process such as visual management and training program, it found that those guidelines had not fully implemented. The project delivery system was lack of process focus and concerns more on relationship inter-parties. It also found thatToyota Way implementation will constrained by the difficulties to change the status quo of project delivery. Moreover, it seems that construction projects need practical guidelines to simplify the Toyota Way implementation in project delivery system such as project flow evaluation and system of reflection.

Questionnaire Surveys

The public procurement sector plays a vital role in the economic development in developing countries such as Vietnam. However, public procurement activities usually perform poorly. This situation can be attributed to ineffective procedures and system (“hardware”) and human resource management (“software”), which occurs at every stage in project purchasing. The poor performance has reduced the effectiveness and efficiency of project delivery in the construction industry, causing delays, cost over-runs, and defects in construction projects. This paper, through working experience and observation by the first author, problems of public procurement were obtained as hypotheses and then validated based on questionnaire surveys and CIS (Construction Industry Structure) model analysis. The survey results indicated a relative correlation with CIS model in description of current construction industry. The study aims to identify issues of public procurement at all stages: pre bid, bid information, evaluation, and award. Based on identified major problems and determined risks, the results are expected to provide a valuable perspective, and thus, to propose necessary strategies to deliver high performance, competition and transparency for the public procurement. In further studies, it is relevant to propose a new model for sustainable public procurement based on the best value approach.

Purpose The purpose of this study is to ascertain the extent to which the practices of small and medium building contractors (SMBCs) conform to lean construction (LC) principles. Ultimately, practical results encourage a discourse on the true potentials and challenges to the holistic uptake of LC principles in the Ghanaian construction industry. Design/methodology/approach This research is based on a qualitative case study approach. The data was obtained through face-to-face structured interviews. Findings Across the cases, it was realized that there is a low-level application of LC principles among SMBCs. There was no indication that lean concepts were used on a company-wide basis in the Ghanaian construction industry. Furthermore, the study revealed that the traditional wasteful approach to managing construction projects was still prevalent among the firms. Practical implications This paper uses the 4P model as a foundation for assessing the extent to which the practices of SMBCs conform to LC principles. Practically, the study also created a certain level of awareness among the SMBCs about LC, LC principles and the benefits of the application of these principles within organizations. Originality/value This study contributes to the body of knowledge as it uncovers the status of LC implementation among SMBCs in the Ghanaian construction industry. The findings that are presented in this paper can be used as a starting point to disseminate the research and practice of LC among SMBCs.

How Stella Saved the Farm is a simple and logical book based on a story which narrates the learning process about making innovation happen. The book is divided in two parts and consists of total nineteen chapters. First part carries nine chapters and remaining are under the second part, which explains the conversion of idea into innovation and then great success. The story is about the competition of two farms one run and managed by animals (Windsor farm) and another by human beings (McGillicuddys farm). Windsor farm is working through change and innovation where the status quo is no longer good enough. Interestingly, in view of poor performance of Windsor farm McGillicuddy is hoping to take over the Windsor farm, but due to the innovations, Windsor farm crosses all hurdles and gets a remarkable status in the business.

Ultimate Objective

Infrastructure, including public works, plays a very important role in supporting a nation’s effort for a better condition of life through economic growth and, in this regard, the Indonesian government is striving to accelerate the execution of a vast number of construction projects. A total budget of around USD 420 billion is made available to realize the program. Meanwhile, public works project delivery in Indonesia still have problems hampering the achievement of its ultimate objective, i.e. producing high quality facilities on time and without cost overruns. A breakthrough in project delivery is needed to ameliorate the condition. This paper describes Indonesia’s struggle to shift from a traditional Design-Bid-Build to a Design-Build delivery system for big public works construction projects. The research consists of a desk study of related existing literature and planning as well as evaluation documents to identify and analyze the challenges and strategic issues of this undertaking to create better value for money. A critical review of a recently issued Indonesian public works’ ministerial regulation on design-build project delivery system is also carried out. Finally, the paper offers important suggestions for a thrust forward to improve the quality of Indonesia’s public works’ construction project delivery and construction industry as a whole in supporting infrastructure development.

The construction industry is one of the most fatal industries, so it is important to pay more attention to safety solutions. Even though work-related accidents are known as major waste in construction projects, little attention has been paid so far to incorporating safety into the lean construction framework. In this research, lean construction theory is reviewed through the lens of safety. That being so, the identified challenges in previous research on improving safety in construction projects are categorized and those related to the concept of lean project delivery are introduced. Then, the principles of the lean construction framework are explained and the relevant changes for incorporating safety into the framework are introduced and discussed. It is expected that this hybrid model would further enrich the lean construction framework. The careful attention of project executives to this model may improve the safety situation in construction projects.

Identification and rank of delay factors in construction projects depending on the project delivery system . The implementation of construction projects depends on many unpredictable factors, which can cause delays in construction works. The article proposes classification of the validity of delaydepending on the project delivery system. Two of them were considered: the traditional system (Design – Bid – Build), where the design stage is separated from the construction stage and the design and build (Design & Build), which consists in entrusting design works and carrying out works to one contractor. The order of validity is based on results of research carried out among participants of the construction project.

Changes will always occur in project construction and can not be avoided. Many factors can cause changes in the construction project. Most dominant factors of cause of changes in project construction is design change. Design changes will have bad impact on the performance of construction projects, especially the performance of cost and performance time. Many factors can be the cause of design changes. Knowing the factors that cause a design change and knowing its behavior is very important to do. Knowing factor and behavioral of design changes that occur in project construction, and then can be managed properly, it will can be reduce the occurrence of design changes in projects construction. With the reduction of design changes will be able to improve the performance of construction projects, especially at cost and time performance. Construction projects carried out by using a project delivery system. Each project delivery system used will have different contractual relationships, rules, and responsibilities of each party involved. These differences will lead to in the occurrence differences in design change in project construction. Selection of appropriate project delivery system to complete a construction project is needed. The purpose of this paper is to provide a conceptual framework that can be used to determine the behavior, and the effect of design changes on project construction at some project delivery system used.

The construction industry is one of the most fatal industries, so it is important to pay more attention to safety solutions. Even though work-related accidents are known as a major waste in construction projects, little attention has been paid so far to incorporating safety into the lean construction framework. In this research, lean construction theory is reviewed through the lens of safety. That being so, the identified challenges in previous research on improving safety in construction projects are categorized, and those related to the concept of lean project delivery are introduced. Then, the principles of the lean construction framework are explained, and the relevant changes for incorporating safety into the framework are introduced and discussed. The proposed model includes a new approach to the Transformation-Flow-Value framework, in order to pay particular attention to safety in construction projects as one of the factors affecting the success of projects, and achieving optimal value for stakeholders. It is expected that this hybrid model would further enrich the lean construction framework. The careful attention of project executives to this model may improve the safety situation in construction projects. The conceptual model presented in this study can be used in the decision making process for project managers as well as research into optimization of safety costs, and eliminating waste (including models for optimizing the movement of machinery, controlling and reducing rework, and designing the site layout).
