Fabrication is a vital part of the extended production system for a construction project. As shop fabrication is a type of manufacturing and ‘lean thinking’ arose in manufacturing, use of lean concepts and techniques in the management of fabrication processes would seem to be a natural and beneficial application. Fabrication can be divided into pre-manufacturing, manufacturing, and postmanufacturing. In a separate paper, the authors have reported the application of lean ‘rules and tools’ to the manufacturing of precast concrete. This paper presents an overview of the entire intervention, which confirms the applicability of lean concepts and techniques to the management of fabrication processes, and illustrates the benefits achievable in improved management of demand, reduced cycle time, greater productivity, heightened work force involvement, and increased revenue and profitability. Suggestions are made for future research.
