Sustainable bim-based integrated project delivery system for construction industry: theoritical framework

Abstract

The construction industry is an open and dynamic system, and the construction project procurement systems practised in the industry are subjected to changes resulting in many newly-innovated procurement systems, which is one of the best solutions for existing issues of conventional procurement. A new era of construction began with the technological improvements with Building Information Modelling (BIM), which is a novel advancement to establish a sustainable construction industry. Several countries have implemented BIM-based approaches to public procurement in recent years, among them, the Integrated Project Delivery (IPD) is an innovative procurement system that facilitates easy BIM adoption. It is evident that the establishment of an innovative procurement system such as BIM-based IPD is essential to adopt sustainable procurement successfully. Hence, this paper presents the drivers, benefits, challenges, and remedial measures, concerning the BIM-based IPD procurement when implementing the sustainable procurement concept to the Sri Lankan construction industry. Accordingly, comprehensive literature review was carried out to identify the above existing gaps in the literature and finally developed a theoretical framework to achieve sustainability targets via BIM-based IPD in construction projects, bridging the challenges of conventional procurement methods.
