Advances in Constructional Engineering

Derived from the lean philosophy in manufacturing, the lean construction theory aims to identify and eliminate various wastes in the construction process through systematic methods, thereby improving project efficiency and quality. Focusing on the core argument of "how to effectively reduce construction waste by applying lean construction theory", this paper analyzes the common types of waste in the current construction process and their causes. Combined with practical cases, it discusses the specific application paths of lean tools such as 5S management, value stream mapping, and continuous improvement mechanisms in construction management. The introduction of lean concepts can significantly optimize resource allocation, shorten construction periods, and reduce construction costs, providing a feasible solution for the high-quality development of the construction industry.
