Quantifying the relationships between buildability, structural quality and productivity in construction

Abstract

Achieving high productivity and quality standards are two important issues in the construction industry. Buildability is an important concept adopted to help raise productivity and quality standards in the industry. While it is generally acknowledged that buildability is able to help raise productivity and quality standards in construction, no study has so far provided quantitative evidence to support the positive relationships between buildability, productivity and quality. Buildability is measured using the buildable design appraisal system in Singapore. Likewise, quality is measured using the construction quality assessment system. Productivity of building projects is measured by means of the floor area constructed per manday. By correlating these quantitative measures, there is empirical evidence to support the positive relationships between buildability, structural quality and productivity in construction.
