Improper design in building projects leads to changes in orders, rework, budget overruns, schedule delays, and low constructability, making it a major cause of waste. The objective of this study is to develop a Lean Building Design Model (LBDM) using lean ideas to improve design quality. To improve the design quality, concurrent engineering is used to develop a learning environment that integrates design needs between project stakeholders. Feasibility of the proposed LBDM is validated using system dynamics. The analysis shows that the LBDM could improve the design quality, thus enhancing project performances.
