EVALUATION OF THE EFFECTIVENESS OF COLLABORATIVE APPLICATION OF BIM AND LEAN IN PROMOTING SUSTAINABLE CONSTRUCTION PRACTICES THROUGHOUT THE DFMA PROCESS.

ABSTRACT

The UK construction industry faces a growing demand for sustainable practices. This research explores how integrating Building Information Modelling (BIM), lean principles, and Design for Manufacture and Assembly (DfMA) can significantly contribute to achieving these goals. Research by Martinez et al. (2013) and Li et al., (2019) highlights the inefficiencies in industry and the resultant impact on productivity and sustainability, necessitating the need for modern measures to address these

challenges. DfMA offers a promising path towards sustainable construction, and this study delves into the combined effects of BIM and Lean within DfMA workflows. BIM's collaborative design capabilities enable early identification and mitigation of

sustainability concerns in construction. Lean principles, emphasising continuous improvement and waste reduction, complement DfMA's focus on resource efficiency. The research examines how BIM can optimise DfMA components for minimal environmental impact during design and construction; and how Lean practices, integrated within a BIM-DfMA framework, can further enhance resource efficiency. This is achieved by reducing rework through improved planning, optimising on-site logistics, and promoting just-in-time deliveries. Employing a qualitative approach, the study combines a literature review, semi-structured interviews and in-depth case studies of UK construction projects that have successfully integrated BIM, Lean, and DfMA. This methodology identifies best practices and barriers associated with this integrated approach. The findings aim to provide valuable insights for UK construction

professionals and policymakers. By exploring the strategic integration of BIM, Lean, and DfMA, this research can inform industry best practices and guide policy development towards a more sustainable future for the UK construction sector.
