Abstract To improve efficiency and reduce waste in Architecture, Engineering and Construction (AEC) projects, Integrated Project Delivery (IPD) has been proposed and used in some projects, revealing great advantages. However, IPD depends heavily on “big room” collaboration, which requires the constant presence of nearly all participants and is particularly difficult for small or medium projects. To overcome this problem, this research aims to develop a dedicated collaboration platform for IPD to achieve more efficient collaboration and replace the highly resource-consuming “big room”. Based on requirement analysis and design of the system architecture, a prototype system is developed and tested in a virtual IPD project. When combined with a few meetings, this collaboration platform can replace the “big room”. This will significantly reduce the difficulty associated with implementing IPD projects and thus promote the adoption of IPD.
