Construction procurement selection: comparative study of public sector vs. private sector

Abstract

Construction procurement selection has been a major research area in recent past. Lots of researches have considered procurement selection by considering the overall construction industry as a one unit. Almost all the previous studies have identified the factors affecting procurement selection but a client wise consideration has not been carried out (Public sector vs. Private sector). Eg: Love et al, (1996), Masterman, (1992), NEDO et al, (1985), Luu et al., (2003), Chan et al, (2001). Since public sector and private sector play equally important roles in the construction industry, factors affecting procurement selection should be separately identified for each sector. Major reason for that is, although there are lots of procurement selection parameters have been identified, the importance level of those factors to the public sector selection may differ from private sector selection. That importance level can be very vital in selecting different types of procurement. Three rounds of Delphi surveys were conducted, to extract a set of exclusive factors and their levels of influence on public sector and private sector and to identify the suitability of available construction procurement options for each sector, with participation of a panel of experts who are engaged in procurement selection in the construction industry.
