Optimizing Construction Projects: Leveraging Lean Management for Enhanced Efficiency and Waste Reduction

This study examines the use of Lean Construction in Turkey, by highlighting how main lean activities influence project results. A questionnaire survey was used to collect information from 269 professionals in the industry about their views on lean culture, focusing on people, continuous improvement, attention to customers, waste reduction and standardization. I relied on literature from experts to design the theoretical basis and structure of the survey instrument. According to the results, while every lean aspect is put into action, it turned out that standardization and efforts to minimize costs have the strongest impact on project success. On the other hand, a few culture - focused strategies and efforts at improvement were associated with negative effects when analyzed with other conditions, signaling that their implementation may be going off track. The outcomes were reviewed alongside literature, confirming that having clear standards, using KPIs guided by customers, engaging with key stakeholders and using feedback early on are essential. According to the research, Takt Time Planning, Work Standard Sheets and prefabrication play a key role in bringing lean methods closer to the goals of the project. The information gathered from the survey helps to build lean construction knowledge and provides better direction for people in the construction industry?s aiming to improve in these areas.
