Mediation effects of innovative procurement practices between the determinants of non-compliance with public procurement guidelines and construction project cost performance in the Nigerian construction industry

Abstract

As part of the effort towards achieving sustainable planning and development of public infrastructure and building projects in Nigeria, Public Procurement Guidelines (PPGs) were highlighted within the procurement policy enacted in 2007 known as PPA2007. Compliance among construction procurement professionals and project parties has been facing serious challenges. Unfamiliarity, misconception and ignorance with the PPGs are identified as the major determinants of non-compliance affecting cost performance of construction projects. The study introduced and tested mediation effects of innovative procurement practices between the identified determinants and cost performance of construction projects in Nigeria. 540 survey questionnaires were used in collecting data, PROCESS macro software was used in analysing 379 useable retrieved questionnaires. Findings indicated that innovative procurement practices have mediated the effects of the determinant of non-compliance with PPGs on construction project cost performances. The study recommends enlightening and educating procurement stakeholders and major project parties on the cost benefits of innovative procurement practices. These may perhaps enhance compliance with PPGs, improve cost performance and sustainable development of projects.
