Abstract
"Mediation analysis" is considered as an important research concept in construction research clusters. In this study, we tested the mediation effects' of enforcement as a compliance mechanism on influencing projects' award considered as public procurement guidelines' (PPGs) compliance barriers that affect the cost performance of construction projects. Compliance with PPGs provided within the context of the Public Procurement Act (PPA) 2007 in Nigeria has been a subject of debate. Data for this study was collected from the procurement stakeholders and construction project parties of nine randomly selected Nigerian federal universities using survey questionnaires. They included project clients, contractors registered with the procurement entities, project management consultants and professional consultants selected using the stratified proportionate random sampling method. The data collected was analysed and tested for mediation effects with Process Macro. The results obtained indicated that enforcement as a compliance mechanism has mediated the large negative effects of influencing project award as PPGs' compliance barriers that affects construction project cost performance. Thus, the study concluded that influencing projects award were identified as one of the major PPGs' compliance barriers affecting the cost performance of construction projects in Nigeria. In addition, enforcement was tested and verified as an effective mediator that mitigates the effects of the influencing projects award on construction project cost performance. The study recommends the prompt implementation of enforcement actions in the form of penalties and strict measures against any defaulting stakeholders and construction project parties. Actions to establish the National Council of Public Procurement (NCPP) as provided by the PPA 2007 are also recommended to ensure practicable enforcement actions.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
