The general approach within lean construction is to make the construction process as it is normally undertaken on the construction site and leaner by reducing non-value generating activities. The reason on why the lean principles are used into rapid construction is to solve the chronicle and congested activities within the time frame of the rapid construction projects. Five principles of lean were made into comparison in the review of three case studies. In many applications of construction concept, the use of rapid construction method components significantly decreased the construction time required for the project. The most significant benefit has been seen in areas where systems have been using it repeatedly. The benefits from lean principles into rapid construction are the shorten of order fulfillment leading times, less project downtime, more innovation and true reduce the chronicle predecessor. This research has also identified eight critical factors of integrating lean with rapid construction that are proven successful which are planning it right, understanding the whole life construction cycle in non price factor view, utilize knowledge and expertise, integrate the team by working with the end to end supply chain in an integrated manner, understand the end to end process, measure performance to include reporting in your own performance, training and benchmarking
