Applying value stream mapping in construction phase of industrial steel buildings by implementing design-build projects and proposing for waste minimization

Abstract

Waste during the execution of a construction project is one of the causes of reducing the project's efficiency, as well as a cause of obstacles to the budget, schedule, use of resources and human resources in order to complete the project within budget to compared with the original cost estimate. In the context of increasingly fierce price competition in the construction market, the application of effective project implementation methods compared to each type of project is also a matter of concerning for investors and contractors. With the application of lean philosophy with VSM (Value Stream Mapping) tool, based on the value stream to find out creating value-added activities and non-value-added activities to eliminate or minimize them to contribute to the effectiveness of the project. The study was conducted in Vietnam.
