Lean Construction: A Sustainability Operation for Government Projects

Abstract

The current state budget allocated for Indonesian government projects has exceeded 10% for infrastructure development. This large budget indicates a need for the construction industry to implement more professional management practices for better cost, time, quality, safety, and environmental impact. Lean construction is used to increase productivity and reduce waste in a project. Therefore, this study aimed to extend lean construction principles to the planning and execution phases of DB projects, where these two entities are integrated into the main contractor. Quantitative and qualitative study methods were used to analyze secondary data from six DB project sites and conduct focus group discussions (FGDs) with expert panels using the Delphi method for consensus. The results showed the factors and variables that influence the implementation of lean construction in government projects in Indonesia.
