The construction industries are distinguished from other industries by a special character in terms of their large size and continuous growth, and the dependence of many industries on them to secure their needs of various facilities, as the construction industry is an industry that produces its main product, construction. Examples of construction projects are buildings and paving roads. Building bridges, establishing schools, hospitals, etc. Most of the construction projects suffer from exceeding the specified time and the secret cost of the project, for several reasons, including the work environment, the country’s conditions, the method of managing the project’s cost, the techniques used in the implementation of the project, and accordingly, the concepts of Lean Manufacturing that help in addressing the causes of waste, in terms of Time and cost, accordingly, this study came to address deviations in the cost or time spent on lean construction techniques and to identify their causes in order to rationalize costs. . In addition to diagnosing waste areas and finding solutions in possible ways through the use of lean construction tools represented in the value flow map, standard work, continuous improvement, and total quality management. To analyze the stages and tasks of any project to reach the sources of waste and try to cancel unnecessary activities and find possible ways to implement them in order to improve the construction work and complete the projects on time and within the planned cost limits, taking into account the maintenance and raising the level of quality.

Lean construction is known to reduce costs, improve profit or increase competitiveness, increase business opportunity and customer base, improve health and safety, improve quality, yield higher employee salaries, shorten production timescales and increase customer satisfaction. With little attention on research of lean construction in Malaysia, it remains a problem of non-standardization in waste elimination strategies thereby sub optimizing waste management in Malaysian construction projects. The objective of this paper is to evaluate lean construction techniques and measure the feasibility in term of their applicability for construction at selected sites in Klang Valley, Malaysia. The study is novel and significant in a sense that it can help to develop reliable management strategies for implementing lean construction technologies at the construction sites. Case studies were carried out as a strategic method and comprehensive survey that covers both questionnaire and interview were adopted as a method of data collection. Likert scale 1 to 5 was used in the written questionnaire with workers in order to assess the level of awareness and acceptance on the need of lean construction techniques for eight construction sites in various places and with various categories (infrastructure and building construction projects) in Klang Valley, Malaysia. Later, semi structural interview was conducted with expert judgment to justify the factors which affect the implementation of lean construction at the construction sites. From the study outcome, it was discovered that both Total Quality Management (TQM) and Industrialized Building System (IBS) were rated by the respondents to be highly effective in both infrastructure and building construction projects.

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.

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.

Purpose Offsite construction approaches and methodologies have been proffered a potential solution for controlling “traditional” projects, especially where high levels of complexity and uncertainty exist. Given this, locations such as Western Australia (WA), where there are unique housing provision challenges, offsite construction method was considered a potential solution for not only addressing the complexity/uncertainty challenges but also alleviating the housing shortage. However, whilst acknowledging the benefits of offsite construction, recognition was also noted on perceived barriers to its implementation, primarily relating to cost uncertainty. This recognition is exacerbated by very limited offsite construction cost data and information available in the public domain. In response to this, this paper sims to provide detailed cost analysis of three offsite construction projects in WA. Design/methodology/approach To hold parameters constant and facilitate cross-case comparative analysis, data were collected from three embedded case studies from three residential housing projects in WA. These projects represent the most contemporary implementation of offsite in WA; where two were completed in 2016/2017 and the third project was still ongoing during the data collection of this research. The research methodological approach and accompanying data analysis component engaged a variety of techniques, which was supported by archival study of project data and evidence gathered from the offsite construction provider. Findings Core findings revealed three emerging themes from residential offsite construction projects pertinent to cost. Specifically, the overall cost of delivering residential housing project with offsite construction techniques, the cost variability of offsite construction residential housing projects as impacted by uncertainties and the cash flow of residential offsite construction projects based on the payment term. These three major cost drivers are elucidated in this paper. Originality/value This research presents new cost insights to complement the wider adoption of offsite construction techniques. It presents additional information to address the limited cost data and information of offsite construction projects available in the public domain particularly for residential housing projects (within the bounded context of WA). It also highlights the further stages needed to enhance data validity, cognisant of universal generalisability and repeatability, market maturity and stakeholder supply chains.
