Lean Construction

Lean Construction started not from industry but from a mix of academics and consultants working to translate lean concepts to construction. Over the last 10 years, an increasing number of companies have implemented lean construction practices in an attempt to improve performance in construction projects. Most companies, and also some researchers, have reported satisfactory results from their implementation. However, there is still a need to provide more extensive analysis of the empirical evidence available to assess the impact of the implementation of lean construction. Lean construction results from the application of a new form of production management to construction. Essential features of a lean construction include a clear set of objectives for the delivery process, aimed at maximizing performance for the customer at the project level, concurrent design, construction, and the application of project control throughout the life cycle of the project from design to delivery. Strategies and support tools have also been developed for implementation. This paper gives a great overview of lean construction techniques. It mentions specific tools and methodologies that have been developed, like look ahead planning, commitment to planning, delivery system, work flow reliability and project management. It also gives a review of benefits of the potential contribution of lean construction to the achievement of productivity enhancement and waste minimization in construction industry. It greatly facilitates the learning of lean thinking in construction and allows for quicker review.
