A Critical Review of Lean Construction for Cost Reduction in Complex Projects

Many countries started to apply lean construction and get benefits of lean construction techniques that can reduce project cost in construction industry, particularly for complex projects. In addition, last planner lean construction techniques started to be widely used instead of current traditional planning techniques for the purpose of decreasing the variation in the processes. Importantly, reducing variation in the project processes can help improve performance and make significant cost savings. Moreover, processes should optimize predictability and facilitate team work and effective communication among participants. In the current scenario, lean construction techniques are not reviewed for complex projects. This paper aims to perform a critical review of lean construction for complex projects.
