Evaluating the effect of construction process characteristics to the applicability of lean principles

Purpose – This paper seeks to test the applicability of lean principles to simple construction processes using discrete‐event simulation.Design/methodology/approach – Quantitative construction data and process mapping of plastering and block‐laying processes were first gathered and established from construction project through field observation and interviews with those involved in the selected projects. Then a simulation model was built to mimic the aforementioned processes to study the impact of certain lean principles. The simulation models became like an experimentation tool where lean principles (e.g. focus on actual objects and map the value stream) were introduced to evaluate their impact on such processes.Findings – Lean principles are effective not only in complicated processes, as proved in previous studies, but also in simple processes. Enhancing the flow of construction materials means the less time they will spend in the value stream and as a result the leaner a process will be. In fact, simp...
