On prefabrication implementation for different project types and procurement methods in Hong Kong

Abstract

The use of prefabrication has been considered as one of the most effective waste minimization methods in the construction context; however, the industry has found difficulties to implement it. Contractors lack experience in using prefabrication and they do not know how to implement prefabrication to their projects effectively. This paper examines possible project types and procurement methods to maximally gain benefits of using prefabricated building components. A questionnaire survey and structured interviews have been conducted. From the results, it should be noted that residential projects and design and build procurement methods are the most effective project types and procurement methods respectively in using prefabrication. Recommendations in effectively implementing prefabrication are also made for each project type and procurement method. This brings early considerations and suggestions to project parties to improve prefabrication implementation. The effects of prefabrication implementation are also considered.
