Building Information Modelling, Integrated Project Delivery, and Lean Construction Maturity Attributes: A Delphi Study

The benefits of adopting collaborative approaches in the construction industry, such as Building Information Modelling (BIM), Integrated Project Delivery (IPD), and Lean Construction (LC), an integrated manner are widely acknowledged academia industry. Once organizations have embraced BIM, IPD, LC integration (BIL), a measurement method for evaluating their progress planning continuous improvement is required. However, there no accepted capability assessment model, Maturity Models (MMs), to effectively assess productivity improvements all three based on interdependencies between them. first step process BIL MM development identifying critical attributes integration. This research investigates interrelationships use maturity models, determining how BIM IPD can support application principles. mixed methods approach was adopted, literature review two-round Delphi survey were conducted data collection. findings revealed number complementarities LC. panel experts agreed upon five major 24 sub-attributes LC, which formed structure presented framework. significance this study provide basis that intend implement manner. Interrelating these framework also supports evaluation organizations’ towards realistic goals improvement.
