(2018). Mediating effects of enforcement on public procurement guidelines' compliance barriers and cost performance of construction projects in Nigerian federal universities: A process macro approach.
The Nigerian Construction industry through its procurement activities is contributing immensely to the economic development of the country.Nigeriaas a developing nation is still working hard to strengthening the public procurement sector through which public infrastructural facilities are developed. Public Procurement Guidelines are the procedural manual guiding public procurement processes. The guidelines are as provided by the public procurement Act PPA 2007, since then compliance with the guidelines has been facing a lot of obstacles. This paper identified and reviewed three major determinants of compliance with the procurement guidelines to include Familiarity with the procurement guidelines, Fraudulent Practices, and Influencing Projects awards. Thus recommended that, to achieve adequate compliance with the procurement guidelines procurement entities need to create room for awareness through training and workshops. The Bureau of public procurement must also ensure prosecution of procurement offences as part of its mandate. In addition, the National Council of Public Procurement NCPP be established and allow to play its role thus limiting the influences of project awards at the ministry level and at the procurement entity level as well.
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 Sustainable Development and Planning VIII 99 of innovative procurement practices. These may perhaps enhance compliance with PPGs, improve cost performance and sustainable development of projects.
