Best practice of prefabrication implementation in the Hong Kong public and private sectors

•This paper evaluates and discusses the effectiveness of prefabrication.•Two leading case studies from the Hong Kong public and private sectors are used.•Their adoption of prefabrication, construction methods and cost effectiveness are investigated.•Discussions on effective implementation for the sectors have also been explored.

Prefabrication has been developed since the 1970s. The technologies have been further developed and improved for the past thirty years. The successful implementation of quality control and construction efficiency has been addressed with support from the public sector. The technologies however did not receive attention from the private sector since prefabrication requires dimensional coordination and standardization in the designs. This situation has changed from 2002 as the Hong Kong government promotes incentives schemes, i.e. gross floor area concessions for private developers to encourage them to adopt prefabrication techniques. This paper discusses and evaluates the best practice of prefabrication implementation in the Hong Kong public and private sectors using two leading case studies. Their adoption of prefabrication, construction methods and cost effectiveness are investigated. Discussions on effective implementation for the sectors have also been explored. The findings provide ameliorated understanding on the best practice of the implementation of prefabrication and provide courage for further improvement and implementation for the industry.
