Relative importance of key performance indicators of construction projects towards buildability at design stage

Abstract

Buildability seeks to improve efficiency of the overall building process by developing construction sensitive designs. The objective of this study is to investigate the relative importance of the key performance indicators of construction projects with respect to buildability at the design stage in the Malaysian construction industry. To achieve this objective, a questionnaire survey was distributed among key construction personnel to identify the most common buildability attributes in Malaysia. Then, an interview with eight construction professionals was conducted to compare the common buildability attributes with project performance criteria such as time, cost, quality, safety, and environment. The results reveal the equal importance of time and cost for buildability of the building, followed by quality, safety, and the environment.
