This paper uses the quantitative decision-making technique, the analytical hierarchy process, to derive prioritized scales for (1) the constructability factors; and (2) the relative contribution of common construction systems in a building superstructure comprising structural frames, slabs, envelopes, roof, and internal walls toward constructability. The identified constructability factors show that to enhance constructability design requirements should be easily visualized and coordinated by site staff, while designs should allow economic use of contractors' resources and enable contractors to develop and adopt alternative construction details. The precast method is rated as the most constructible construction method, indicating its better performance in facilitating efficient and safe construction in the busy urban environment in Hong Kong. However, the methodology adopted in this study should be of international interest, especially for those desirous of improving constructability of designs with different contextual backgrounds.
