Critical success factors for adopting building information modelling (BIM) and lean construction practices on construction mega-projects: a Delphi survey

What is it about?

Building information modelling (BIM) and Lean Construction (LC) have gained momentum in the last decade. The research investigates critical success factors (CSFs) that enhance integration between BIM and LC practices on construction mega-projects. The Delphi survey technique was utilised to gauge opinions of a panel of sixteen (16) experts through a two‐round Delphi questionnaire survey. Panel responses were scrutinised using inferential and descriptive statistical techniques. Thirty (30) CSFs were identified in the literature. The top ranked factor out of 30 that supports LeanBIM synergy was ‘collaboration in design, construction works, and engineering management. Other top rated CSFs were centric on people, data and technology elements. The research findings are important for project stakeholders, organisations, contractors, engineers, and local authorities who implement LC and BIM synergies in construction mega-projects. The research recommends further hands-on training to increase the integration of BIM and LC practices in the architecture, engineering, and construction (AEC) industry and to enrich the extant body of knowledge in construction of mega-projects.
