The role of modular construction and BIM technologies in sustainable construction and demolition waste management

Abstract

Construction and demolition activities significantly contribute to global waste generation, necessitating sustainable measures. This thesis explores advanced C&DW management through Building Information Modeling (BIM) and modular construction techniques. In the initial phase of the study, a comprehensive text-mining analysis of 493 scholarly publications (2009-2024) reveals key themes and temporal trends. The cooccurrence analysis identified three distinct clusters centered on C&DW management, highlighting strong correlations between "sustainability" (Links=41), "BIM" (Links=46), and "C&DW" (Links=46). Thematic development and evolution analysis indicated that during the third period (2018-2021), transversal themes included Material Passport (OCC=92) and Prefabrication (OCC=482). In the fourth period (2022-2024), transversal themes encompassed Digital Twin (OCC=44), Waste Minimization approaches in BIM (OCC=64), and Decision-Making Systems (OCC=64). Strategic diagrams and Temporal evolution mapping generated by SciMAT software illustrate the progressive integration of BIM tools like digital twins, Material Passport, Prefabrication, and Decision-Making System, offering avenues to optimize waste reduction. The subsequent part of the study explores modular construction techniques for their potential to mitigate material waste and enhance sustainability in building practices. Significant research interest since 2015, coinciding with the UN Sustainable Development Goals (SDGs), is observed. Keyword trends have sustained interest in recycling since 2014. Cluster and network analysis highlight "Recycled Aggregate Concrete (RAC)" as a high-impact theme (confidence 100%).The importance of the mechanical properties of RAC in modular construction is also emphasized.
