A sustainable procurement approach for selection of construction consultants in property and facilities management. Issue 1 (2nd September 2019) - Lam, Terence Y.M.
Abstract : Purpose: Outsourcing architectural and engineering services is a trend for public-sector construction projects. This study aims to examine what tender selection criteria should be considered when assessing the performance outcomes of consultants in relation to sustainable design, construction and management of buildings within the context of property and facilities management of existing building portfolios. Design/methodology/approach: Combined qualitative-quantitative methods are adopted to examine the causal relationship between sustainable performance outcomes and influencing factors, using primary data collected from the estate offices of the UK universities, which form a unique public sector. The performance factors identified form the basis of selection criteria. Findings: The qualitative multiple-case interviews identify economic, environmental, social and functional sustainability measures as the attributes of performance outcome. The quantitative hierarchical regression analysis generalises that sustainable performance outcomes can be significantly influenced by task and contextual performance factors. Research limitations/implications: The scope of the study is limited to university estates. Further research should be conducted on other property and facilities management and construction-related organisations so that the sustainable procurement approach developed by this research can become more robust and applicable to the wider public sector. Practical implications: At the tender stage, estate managers should adopt a sustainable procurement approach for selection of construction consultants: focussing on the significant task performance (project staff and execution approach) and contextual performance (collaborative consultant frameworks) influencing factors to optimise the project sustainability outcomes in relation to economic, environmental, social and functional values. Originality/value: The sustainable procurement approach developed by this research benefits property and facilities management, as well as construction disciplines within the wider public sector, thus contributing to the government construction policy on promoting sustainability to the built environment.
