Developing a strategic model to improve the reuse of construction material by integrating CBM and BIM

Abstract

Circular Business Models (CBMs) are an evolving concept in the construction industry. These models help organizations in reducing the wastage of materials, increasing the judicious usage of raw materials, maintaining material productivity over the lifecycle and enhancing overall sustainable productivity in construction projects. The aim of the present work is studying the current status of implementation of BIM tools in building demolition projects in construction industries in the Chennai Region, Tamil Nadu. The present work assessed the employees’ awareness of BIM and LCA, their attitude towards and support for BIM adoption, perceived performance improvement because of BIM and barriers in the implementation of BIM across the selected construction demolition projects. In addition, the study proposes a framework for integrating tools like BIM and LCA in construction demolition projects. The results show that the level of awareness and extent of implementation of BIM has been mediocre. The proposed framework that integrates BIM and LCA using CBM approach could drastically reduce wastages and enhances productivity in construction projects.
