PurposeProcurement management in infrastructure development has gained considerable attention in developing countries. It is because of the success in the developed nations. Studies have shown that Nigeria's infrastructure development needs far exceed its current provision. Also, studies are scarce to reveal whether procurement management has been successful in infrastructure development projects in Nigeria. Therefore, this paper investigated the root cause of the perceived encumbrances impeding procurement management in infrastructure development projects and proffered policy measures to improve future Nigeria's infrastructure development.Design/methodology/approachData were collected via unexplored exploratory virtual interviews and selected cases from secondary sources. The engaged construction and engineering consultants have been involved in the procurement management of infrastructure projects in Nigeria. Thematic analysis was adopted to analyse the collected data.FindingsThe root causes of the pitfalls that emerged from the study include lack of competition and transparency, embezzlement and mismanagement of public funds, snail speed bureaucracy and bottleneck and lack of skills and knowledge. Others are collusion/bid-rigging/price-fixing/cartel formation, corruption, lack of professionalism, unbridled politicking, embezzlement and mismanagement of public funds, incompetence of tender boards, lack of patriotism to national service and lack of government organisations’ procurement capacity.Research limitations/implicationsThis paper is restricted to unravelling the encumbrances in procurement management of Nigeria's infrastructure development projects. Future research is desirable to adopt a quantitative approach for more extensive coverage and validate findings from this paper.Practical implicationsThe paper findings, including those learnt from each case study evaluated, would undoubtedly influence policymakers and construction and engineering practitioners on the key strategies to employ in implementing future procurement management in Nigeria's infrastructure development projects.Originality/valueThis paper would assist policymakers and other stakeholders desirous of improved infrastructure to focus their priorities in mitigating the identified root cause hindering procurement management in Nigeria's infrastructure management.
