Transferring these principles from manufacturing to the construction domain is of ongoing interest for construction researchers. However, modifying real construction processes is expensive, time consuming and difficult. This paper reports interim results of a study to evaluate lean principles when applied to construction using computer simulation. Data for a structural steel erection process was modeled in ExtendÃ’ to form the experimental tool for evaluating lean principles. In all cases, the simulated principles improved project performance. Performance improved dramatically when all principles are simultaneously applied. However, the erection process became volatile and fragile when it was subjected to changes and uncertainties from outside of the process. Maintaining a zero buffer at the erection site made the process extremely fragile. This study demonstrates the need for a broad systems view when one is considering lean modifications to a construction process.
