In view of the need to improve the buildability of building designs pursuant to an industry-wide study, a Buildability Assessment Model (BAM) has been developed for use in Hong Kong by adapting the Buildable Design Appraisal System of Singapore. This paper is aimed at evaluating the practicalities of implementing the BAM, and identifying any possible resistance and corresponding improvement strategies based on a questionnaire survey with industry practitioners. Results showed that the BAM is a useful tool for assessing the buildability of completed designs. There is, however, inherent resistance hindering the smooth implementation of the BAM, such as designers valuing aesthetics more than buildability and the lack of incentive conducive to buildability improvement. Measures for enhancing buildability are suggested, including the establishment of formal channels for coordination and communication between contractors and designers. Independent survey results indicate that consultants and contractors have the consensus that the BAM would help to improve buildability in the longer term. Together with other pull and push factors, the benefits to be brought about by such measures and the feasibility of possible legislation are analysed.
