INTEGRATING BIM AND LEAN CONSTRUCTION FOR ENHANCED PROJECT DELIVERY IN LARGE-SCALE INFRASTRUCTURE PROJECTS

Abstract

The project delivery in civil engineering should be of capable quality and should integrate the dimensions of time, cost, quality, and sustainability into the systematic framework of management. This paper will focus on how both Building Information Modeling (BIM) and Lean Construction offered together can enhance efficiency and minimize delays in mega projects. The data on 210 project professionals engaged in road and bridge projects were gathered using surveys and site visits and project documents. Descriptive analysis indicated a relatively high spread of BIM and Lean practices adoption, and the correlation analysis indicated that BIM adoption, Lean practices, and the project performance indicators are strongly positively associated. Structural Equation Modeling (SEM) further established that BIM and Lean collectively increase project efficiency and this greatly mediates the degree of cost control, time performance, and sustainability results. These findings highlight the need to note that the combination of digital tools and processes that are organized structurally is not merely technical but also poses a strategic opportunity to integrate collaboration, transparency, and resilience into the process of providing infrastructure. Practical implications are that phased integration plans, training, and adoptive policy need to be in place to address obstacles which can be cost, cultural resistance, and skills shortages. All in all, integrating Lean and BIM into a single package proves to be the most innovative direction towards smarter, greener and more efficient construction project delivery.
