(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.
Problems associated with solid waste management (SWM) have proved to be complex in origin and in solution. In Nigeria SWM is characterized by ineffi cient collection methods, insuffi cient coverage of the collection system and improper disposal of solid waste. This chapter reviews the current status of SWM in Nigeria. For SWM to be sustainable in Nigeria a greater fi nancial investment needs to be made, possibly including provision through local rates and taxes. In addition, appropriate technologies in line with the nature of garbage generated need to be explored. Finally the effort and role played by the informal sector in SWM in Nigeria needs to be recognised, but there is urgent need for this sector to be formalized so that its role can be geared towards achieving sustainability.
