Lean construction is as an effective management tool to enhance the productivity in construction field. Large research is being done in recent past and is an on-going process to adopt lean principles from manufacturing industry to the construction industry. In order to improve the efficiency, reduction of waste, the lean construction has been introduced as new management tool. There are many challenges in implementing the lean concept in construction industry in India. Due to lack of attention and illiteracy towards the lean management principle, stake holders associated to this like builder, contractor, and engineering and project management firms etc. are still in process of adopting this principle for construction project. In this project report efforts are made to find out main barriers towards the implementation of lean techniques in Indian construction industry with the help of questionnaire survey and actual site implementations are made to develop a process map for on-going projects. Results of the survey showed that some of the lean techniques should be given more focus to enhance the process. The framework results show that the NVA (Non Value Added) and ENVA (Essential Non Value Added) activities have the highest impact on the project duration. Therefore with implementation of the proposed lean techniques, the NVA and ENVA activities have found to be improved and their durations can be reduced considerably.

Purpose Non-value adding activities or wastes in the lean term have been the major challenge of the construction industry. Numerous studies have been conducted to investigate how such wastes can be reduced so as to improve the performance of the construction industry. However, the aspect of bricks production process (BPP) has not been extensively covered. Therefore, the purpose of this paper is to investigate the application of lean manufacturing concepts in BPP with a view to identifying the various wastes in the practice, the causes of these wastes and how such wastes can be reduced. Design/methodology/approach Mixed methods research design was adopted by the researchers where literature review was first conducted to establish the fundamental theories and practice standards of lean manufacturing process. Thereafter, a phenomenological study was carried out in a Shelter Clay and Brick Factory located in Minna, Niger State, Nigeria. The data obtained in the phenomenological study were analyzed through content analysis. These data served as the basis for the validation survey that subsequently followed the phenomenological study. Findings The findings in the study show that poor or inadequate supervision is the main factor responsible for wastes such as excessive drying of bricks, overheating of bricks and re-glazing of bricks in Nigerian BPP. Research limitations/implications The study focused on the various wastes in Nigerian BPP. It also focused on the various lean tools/techniques that can be adopted to reduce the wastes. Aspects such as the percentage of the wastes and their cost implication on the factory were not covered during the study and could be further investigated by prospective researchers. Practical implications The study provides knowledge on how lean thinking can be adopted to reduce wastes in BPP. Such knowledge may be beneficial to the present and prospective bricks producers. This implies that the proposed framework in the study allows producers of bricks to identify gaps in their implementation efforts, focus attention on areas that may require improvements, and access the benefits of lean approach in their factory products. The proposed framework may also be beneficial to the academics. Originality/value This paper first gain originality in the study context to propose for a lean framework that can be adopted to reduce wastes in BPP. Furthermore, the paper has not been previously published and all the information obtained from other sources are duly referenced.

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.

Standard Time

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.

Speed-driven projects require extensive planning and coordination for their successful execution within the specified time and cost. With an increasing demand for flash track execution, more efficient ways for project implementation is needed. Lean construction is having a profound impact on the construction industry, which is perceived to be suffering from cost and schedule overruns. This review paper investigates the use of various lean tools and principles in flash track projects and if there is any synergy between lean and flash track projects to improve productivity and schedule performance. Through rationalizations and with the help of case studies and theoretical evidence found in literature, eleven lean tools and eight lean principles have been analyzed for their synergy with flash track construction. The results indicate that all except one lean tool (Just in Time) and one lean principle (reduce inventory) facilitate successful implementation of flash track project.
