Building Information Modeling (BIM) has gained rapid acceptance in the building industry in recent years in Hong Kong; both the government and the industry practitioners realize this irreversible trend of changing gradually from traditional 2D representation of building product and fragmented contributions from the stakeholders to 3D product model and streamlined lifecycle management in the near future. This research presents an overview on the implementation of BIM, its current state of practice in Hong Kong. While the primary intention is to introduce the BIM-related works and preliminary benefits; the authors also intend to identify the obstacles and challenges faced by industry practitioners of such implementation in Hong Kong from social and technological contexts. A case study is used to illustrate the benefits of BIM implementation by a large contractor, as well as the technical limitations and difficulties steering toward the "ideal scenario" envisaged by using BIM technologies.
