The issue of time and cost consuming activities such as rework, conflicts, and overlapping has received considerable critical attention by construction industry. Using benefits of lean thinking has a significant impact on the construction processes in order to achieve perfection at the whole building life cycle. The Lean construction methodology is an increasingly important area for the construction industry due to its effect on cost and value. However, the Lean construction methodology is not implemented by the construction industry professionals due to the complexity of methodology, change requirements in company organization, lack of guides for the process, etc. This study provides a comprehensive framework that focuses on defining processes which enables lean methodology implementation by demonstrating the whole building lifecycle. It will provide a broad explanation for the characteristics of each level and logical relationships between concepts. The levels of the maturity framework such as; Level 0 Traditional Construction, Level 1 Lean Construction, Level 2 Lean Construction, and Value Engineering, Level 3 Lean Construction, value engineering, and building information modeling, and Level 4 Lean Construction, value engineering, building information modeling, and data analytics were identified with a comprehensive literature review and comprehended. The findings of the study will be helpful to increase comprehensibility and implementation of lean concept.
