中国城市化进程的加快需要住宅工业化作为其坚强后盾，然而目前中国住宅工业化还没有找到一个较好地发展途径。因此，如何成功推进中国住宅工业化进程，成为建筑领域关注的热点。作者基于在建筑领域多年的工作经验，欲将制造业的发展模型引入到住宅建设行业。通过分析住宅工业化的三个成功关键因素，提出推进住宅工业化的关键技术，即预制件技术和虚拟施工技术，以期望为中国住宅工业化的发展提供参考。

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.
