ADVANCING SUSTAINABLE CONSTRUCTION MANAGEMENT THROUGH BIM PRACTICES AND THEIR IMPACT ON MEP PROJECT EFFICIENCY

Abstract

This study presents a comprehensive academic investigation into the role of Building Information Modelling (BIM) in promoting sustainability and operational efficiency within the design and construction of Mechanical, Electrical, and Plumbing (MEP) systems. Adopting a mixed-method research approach, the study integrates a Delphi survey to assess both the extent of BIM adoption and its measurable influence on key sustainability indicators such as material waste, energy efficiency, cost control, and stakeholder collaboration. Empirical findings reveal that the implementation of BIM led to a 54% reduction in material waste and a 17% improvement in energy efficiency, underscoring its environmental benefits. Additionally, BIM usage was associated with a 20% decrease in rework, reflecting stronger interdisciplinary coordination and reduced design errors during project execution. The research also highlights enhanced stakeholder engagement facilitated by BIM, which contributed to improved project delivery and cost-effectiveness. Furthermore, the study introduces a practical, context-specific BIM framework tailored for Pakistan’s construction industry, demonstrating its real-time applicability on active sites. The findings validate BIM as a critical enabler of sustainable construction practices by ensuring timely completion, reducing financial overruns, and optimizing overall project performance. The study concludes with a call for strategic investments in digital infrastructure, procedural improvements, and supportive government policies to address barriers to BIM implementation in developing countries.
