Purpose – The purpose of this paper is to depict the developmental process of a buildability assessment model for use at the scheme design stage of building projects, which have a priority requirement for functional performance rather than aesthetic performance.
Design/methodology/approach – First, major decisions made at the scheme design stage of building projects were identified through pilot interviews and a questionnaire survey on designers. Second, these decisions were rated for their relative importance towards buildability through another questionnaire survey on contractors, analysed using the reliability interval method. Based on these results, a list of buildable and non-buildable features and their impacts is compiled by interviewing major contractors. These findings were incorporated into a modified framework of buildability assessment for complete design, substituting information available at the scheme design stage. Validation was carried out using four sample projects and feedback from practitioners.
Findings – The results obtained from the Scheme Design Buildability Assessment Model have been demonstrated as reflective of actual buildability level. Buildable and non-buildable features, as exemplified by typical building projects in Hong Kong Special Administrative Region, have been identified.
Originality/value – This is the first model which provides a tool for use by the design team to evaluate the buildability of their designs at an early stage, so that necessary improvements can be made without affecting the development program.
