With the rapid development of urbanization in China, housing industrialization is needed to strongly support the urbanization.However, at present, there is still no an applicable approach to guide the development of the housing industrialization of China.Thus it has become a focus how to successfully advance the process of housing industrialization in the construction industry.On the basis of the many-years experience in the construction field, author wants to introduce the developmental mode of the manufacture industry into the housing industry.This paper presents the three key factors of success in housing industrialization and further provides the critical techniques of impelling housing industrialization, i.e.precast technique and construction virtual prototyping technology.It is cordially expected that this research can provide a reference for the development of housing industrialization in China.

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.
