Analysis of lean construction practices at Abu Dhabi construction industry

Abstract

What are the current construction wastes in Abu Dhabi (AD) construction industry and what are their main causes? What are their impacts on construction projects cost, quality, and speed? Is the industry familiar with lean construction concept and methods? What are the currently used lean techniques in AD construction industry? Does the industry need to adopt lean construction techniques? The purpose of this paper is to analyze the current lean construction practices amongst Abu Dhabi construction companies and to develop a practical framework for adopting lean construction techniques and measuring lean performance. An industry survey is used to collect information and data from local construction companies in Abu Dhabi area. Collected data and information are organized, analyzed, and used to answer research questions. This study identified and categorized 27 construction wastes in AD construction industry, specified 18 key causes of these wastes, and estimated their extent and impact on project cost, quality, and speed. The study also analyzed the extent and impacts of 23 lean techniques in AD construction industry. The study found that only 32% of surveyed companies are currently familiar with and/or already using lean construction techniques and concluded that the industry is in high need for a practical framework, such as the LPDS of LCI, for adopting lean techniques. The credibility of the research results and findings is dependent on the accuracy and reliability of collected data from construction companies. Implications: This research identified current construction wastes and their causes, analyzed the current uses of lean techniques, and developed a practical framework for effectively adopting lean techniques in AD construction industry.This study will increase the awareness of lean construction practices amongst AD construction companies. It will also help the industry understand the impacts and causes of current construction wastes and provide the industry with a practical framework for adopting lean techniques. This study also may serve as another model for other countries that are starting to implement lean construction.
