Information integration has been recognized as key factors for effective construction supply chain (CSC) management. It acts as an enabler to implement lean production philosophy by facilitating information sharing, joint decision making, process integration and team cooperation. This paper aims to explore an nD modelling based information system to enhance the CSC information integration and sharing. Mixed methodologies including literature review, theory analysis and workshop discuss were employed. The research identified that lack of information integration across the CSC is the main barrier to effective supply chain information management. An nD modelling based two level construction supply chain information system, consisting of operational project supply chain extranet and strategic organizational supply chain extranet, was proposed and illustrated in detail. Application of the system shows it could enable construction information integration and interdisciplinary analysis to facilitate collaborative decision making and process integration, and also provide a solution to match the principle of long term cooperation for supply chain management with the actual unique and transient nature of project based construction.
