Resumen
The use of electronic (e-) procurement to support the execution of supply chain management activities in the different industrial sectors is permeating all regions of the world. However, in countries in sub-Saharan Africa where there is a significant level of corruption and unethical practices in the procurement process, there is a need for a better understanding of how e-Procurement can help to check the incidence of corrupt and unethical practices in construction project delivery. This study relied on a cross-sectional survey of 759 respondents, including architects, builders, engineers, estate/facilities managers, contractors, construction/project managers, quantity surveyors, supply chain managers and others to identify and analyse the anti-corruption capabilities of e-Procurement in construction project delivery in Nigeria. The results of the descriptive statistics, relative importance index and principal components analysis identified 18 anti-corruption capabilities in e-Procurement in construction project delivery with the three most important ones being the capability of e-Procurement to ensure good inventory management/record keeping; accountability by providing audit services trail and minimise direct human contacts during bidding. The key underlying dimensions of these capabilities include the advantage of e-Procurement over the traditional paper-based method; transparent bidding process and increase in competition in construction project delivery process. The findings of this study have implications, especially, on the use of e-Procurement to curb corruption in construction procurement activities.
