The purpose of this paper is to examine various uncertainties underlying the concept of sustainability in construction and built environment (SCBE) and determine if SCBE is a “wicked problem” (WP).
Qualitative text analysis and inductive reasoning are used as research methods in this paper. Text analysis of extant literature is performed to categorise the uncertainties underlying the concept of SCBE. Inductive reasoning, based on these categories of uncertainties and the characteristics of WPs provided in the seminal work of Rittel and Webber (1973), is used to assess SCBE as a probable WP.
Six distinct categories of uncertainties underlying the concept of SCBE are developed: temporal uncertainty, spatial uncertainty, stakeholder uncertainty, societal uncertainty, dimensional uncertainty and assessment uncertainty. The inductive reasoning provides a prima facie evidence that SCBE, underpinned by these uncertainties, is a WP.
To the best of author’s knowledge, this is first of its kind analysis that assesses SCBE from a WP perspective by a systematic categorisation of underlying uncertainties. The findings necessitate a new approach for the context-specific conception of sustainability to commensurate with local values. They also provide a sound academic base to challenge the positivist notions generally associated with SCBE, reflected in sustainability assessment and rating systems currently pursued globally as a means of promoting SCBE.
