Abstract

Recent studies found that imminent measures should be taken to address buildability problems in the Hong Kong construction industry in order to improve productivity. Drawing from the experience of Singapore, where buildability is beneficially quantified by the Buildable Design Appraisal System (BDAS), a project has been carried out to establish a Buildability Assessment Model (BAM) for scoring buildability of building designs in Hong Kong. The research is aimed at establishing a mechanism to measure and appraise the buildability of different building design decisions. The BAM was developed first by identifying the relevant factors and attributes of buildability, taking the contextual background of the Hong Kong construction industry into consideration. A series of structured interviews and questionnaire surveys were carried out with the contributions of over 200 experienced practitioners in Hong Kong. The core research methodology included Factor Analysis and Analytical Hierarchy Process. The BAM was eventually validated by the scoring of representative projects and a questionnaire survey. In the long run, the BAM can be used to benchmark buildability of different building designs in Hong Kong. This would in turn encourage design professionals to develop more buildable designs. This approach can be adapted in other countries where buildability plays an equally important role to improve productivity of the construction economy.
