Abstract
Waste in construction projects is a significant research topic globally, including in Indonesia. The lean construction concept identifies any waste as a non-value added. Different waste management techniques categorize waste as either physical or non-physical. Based on literatures explain that most of project construction is bad on waste registration. The paper focuses on implementing lean construction for physical construction waste. Furthermore, this article presents Indonesian case studies to illustrate the impact of lean construction on building projects. The study analyses waste management impacts across three periods of time. Lean waste management provides an early warning evaluation in the short term that are used as an indicator, so the project can evaluate and follow up as an effort to reduce waste, which in this study shows a reduction of waste from 2.1% to 1.7%. Addressing common waste in the medium-term increases project productivity by 50% and improves cost and duration efficiency. It reduces many possible wastages due to defects, overproduction, non-utilized talent, inventory, transportation, motion, waiting, and extra processing (DOWNTIME). Sustainable waste reduction practices can become a productivity standard in the long term by continuously improving the cycle of writing, categorizing, analysing, and writing for each job.
