Traditional construction material procurement is being replaced by electronic commerce construction material procurement now. Building Information Modeling (BIM) has shown benefit and practical value in construction material quantity takeoff and cost estimate. However, very few efforts have been directed to the application and integration of BIM in e-commerce material procurement.

The author compares the present commercial BIM and non-BIM based quantity takeoff and cost estimate software, presents one solution to link the BIM with RSMeans Unit Price cost data to generate more accurate cost estimate reports, identifies the possibility and potential benefit of integrating BIM and e-commerce software solutions in material cost estimate and procurement process, designs one weight coefficient based model to evaluate the performance of material suppliers, proposes a framework to integrate BIM with e-commerce in material procurement and supplier performance evaluation process, and develops a preliminary display version of BIM integrated with e-commerce software system.
