Abstract

This article was published in the Journal of Construction Engineering and Management [© ASCE] and the definitive version is available at: http://dx.doi.org/10.1061/(ASCE)CO.1943-7862.0000543A lack of value-based decision criteria leads to an inability to effectively compare prefabrication and off-site production with conventional construction, which inhibits the realization of benefits of off-site approaches. This paper develops value-based decision criteria and quantifies their relative importance for assessing building technologies systematically. The research employed a multimethodological strategy within a broad case-study-based design, with six large house-building organizations in the United Kingdom. These companies together accounted for more than one-tenth of new-build home completions in the United Kingdom. More than 50 criteria were developed, grouped under cost, time, quality, health and safety, sustainability, process, procurement, and regulatory and statutory acceptance. Cost was ranked most important, which, coupled with time and quality, predominated technology selection in these companies. Sustainability, process, and procurement were weighted lower, whereas health and safety and regulatory and statutory acceptance were deemed compulsory, hence offering no trade-off opportunity. A lack of incorporating innovative sustainable technology into corporate strategy was observed. The developed criteria and the systematic process should help house-building organizations manage technological innovation and hopefully achieve more informed corporate decisions
