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.

Prefabrication and barriers to entry—a case study of public housing and institutional buildings in Hong Kong
TL;DR: In this paper, the authors compared the Herfinndahl-Hershamann indices (HHI) of the public housing and the institutional building sectors and concluded that prefabrication requirement by itself does not seem to have raised the barriers to entry to prefab-ricated housing construction.

A study of measures to improve constructability
TL;DR: In this article, a comprehensive survey has been carried out on contemporary literature, i.e. from 1990 onwards, to trace the development of the buildability and constructability concepts and the common approaches of improvement.

Constructability rankings of construction systems based on the analytical hierarchy process
TL;DR: In this article, the authors used the analytical hierarchy process (AHP) to derive prioritized scales for constructability factors and relative contribution of common construction systems in a building superstructure comprising structural frames, slabs, envelopes, roof, and internal walls.

Improving building project performance: how buildability benchmarking can help
TL;DR: In this paper, the relative correlations between different buildability attributes and construction performance in terms of time, cost, quality and safety were investigated, and it was found that construction time performance has strong positive correlations with buildability in the design of external wall elements, simplicity of assembly and installation considerations, while other design attributes affect cost, QoS, and safety performance to varying degrees.

Environmental Cost-Benefit Analysis of Prefabricated Public Housing in Beijing
TL;DR: In this article, the authors compared the costs and benefits of prefabricated public projects and traditional projects based on a questionnaire and field investigation, and reported a costbenefit analysis of the changing rates of construction costs and environmental benefits (energy consumption, water usage, construction waste, steel and concrete usage, dust and noise pollution).

Effectiveness of ISO 9000 in raising construction quality standards: some empirical evidence using CONQUAS scores
TL;DR: In this article, the authors investigated the relationship between certification to ISO 9000 standards and the achievement of higher construction quality standards as indicated by CONQUAS scores, and they found that the implementation and certification of quality management systems to ISO 9001 standards in construction firms has helped them to achieve higher quality standards through higher conquAS scores.

The Conceptual Relationship between Construction Quality and Economic Development
TL;DR: In this article, the authors explored the relationship between the Singapore economy and quality in the construction industry, and proposed a conceptual framework which depicts this relationship, showing that there is a link between construction quality and economic development in Singapore.
