Concurrency in BIM-based project implementation: An exploratory study of Chongqing Jiangbei international airport’s terminal 3A

Abstract

Many of the shortcomings associated with dated design and construction methods as well as project fast-tracking can be addressed by exploring the concept of concurrency facilitated by Building Information Modelling (BIM). From a BIM perspective, concurrency facilitates the involvement of stakeholders from very early on during the lifecycle of a project. Leveraging the 5 W/H (Who, What, When/Where, Why and How) method of exploratory research, this paper explores how BIM and Concurrent Engineering (CE) at Terminal 3A of the Chongqing Jiangbei International Airport compares with a historical exemplar of BIM deployment in the AEC industry. Based on existing definitions of CE, we compare both projects to determine their conformance to three CE criteria: 1) compressed project duration, 2) enhanced product value, and 3) reduced project costs. We also review their use of collaborative tools and techniques. The paper shows how the success of BIM-based projects can be rationalised by CE.
