Construction projects are composed of a large number of contractors, subcontractors, and suppliers that comprise the project supply chain. Construction supply chain management as a field of study concerns itself with improving the coordination of these firms to improve project performance along various metrics such as speed, cost, reliability, quality, etc. In order to link the construction supply chain well, information sharing is a basic requirement and function in the supply chain management system. Without the information sharing, the supply chain partners cannot communicate each other and connect construction operation to synchronize and streamline all communications among the company. However, the rise of the interconnectivity between different information systems over the Internet impacts construction processes, thus the defective characteristics of the construction industry can be overcome by an assistance of technology. This paper describes the prototype and system of e-Hub Construction Supply Chain Management (eHub-ConSCM) System for information shared service in executing the construction projects. The information needs for eHub- ConSCM System are illustrated, a general system architecture is describe and the implementation of eHub- ConSCM system is presented.
