Abstract
Purpose - Prequalification of contractors is a very important step in construction project procurement under the contract "Due Process" policy in Nigeria. The purpose of this study, therefore, is to investigate the impact of contractors' prequalification on cost, time and quality performance of construction projects. Design/methodology/approach - Data were collected with the aid of a questionnaire addressed to construction practitioners selected from clients, consultants and contractors' organizations. Also archival data on 77 completed building projects relating to prequalification assessment of contractors and project delivery variables were sourced from consultant quantity surveyors. The data were analysed with the aid of mean score and one-way analysis of variance (ANOVA). Findings - The results show that contractors' prequalification has significant impact on time and quality performance of construction projects as evidenced by p/-values of 0.039 and 0.030, respectively. Practical implications - The findings should provide a valuable reference for clients and consultants during contractors' prequalification and contract award. Originality/value - The outcome of this paper will assist clients and consultants in the construction industry to carry out objective assessment of contractors' potential performance in relation to project goals prior to contract award.

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
