The Need for an integrated cost modelling framework for building information modelling

Abstract

The shift from traditional procurement systems, towards more collaborative procurement systems which are backed-up with information and communication technology (ICT), is becoming the new trend in the present day construction industry around the world. Integrated Project Delivery (IPD) and Building Information Modelling (BIM) are the two most emerging and widely used systems to achieve this shift. These concepts are likely to be the new industry standard in the near future due to their collaborative nature, ability to implement sustainable procurement strategies, risk and reward sharing basis and high efficiency of construction by promoting dry construction. Yet, the Sri Lankan construction industry is still following the traditional rigid and highly separated procurement systems with traditional 2D computer aided drafting (CAD). Therefore adopting and continuing BIM and IPD will generate many issues and risks since the industry is used to the absolute opposite of the underlying principles of both BIM and IPD. Under this context, a research is conducted with a broader aim of identifying the potential reshuffle of risks, which a construction project in Sri Lanka would be subjected, if it is delivered through BIM based IPD. This paper contains the preliminary findings of a literature review conducted on the current risks the industry faces and on identifying the requisites of BIM and IPD.
