Researchers and construction professionals have adopted lean manufacturing concepts and strategies in the development of lean construction principles. Much of these efforts have centered on the field construction activities themselves. However, the ideology of lean focuses on the entire value stream of an operation from raw material to final product delivery. Waste and inefficiency is still evident throughout construction supply chains. The goal of this paper is to investigate improvement opportunities in the construction industry, utilizing the practice of lean supply chain management. A case study was conducted to achieve this goal and investigate applicability in the field. An assessment was done with a local contractor already familiar with lean. From this study came a number of findings and observations: differences between lean and non-lean fabricators and effects on construction, effective staging of materials. From these findings, improvement recommendations are prepared for future projects.
