Cohesion between Cost, Time and Quality Performance of Civil Engineering Project: Evidence from Contractor Prequalification Criteria

Abstract

Setting cost, time and quality targets for civil engineering project is motivated by the need to have an instrument that would dictate and control activities of the contractor towards delivery of product that meets client’s expectations. This study, which examines the relationship between cost, time and quality performance of civil engineering project, is premised on the importance of showing whether cost, time and quality performance of civil engineering project demonstrates different correlation patterns on one part or exhibit different significance relative to contractor prequalification criteria on the other part. It uses questionnaire to obtain the needed data and analysis achieved through spearman’s rank correlation and regression methods. It establishes the nature of the cohesion between these three parameters. Consequently, both strong and weak positive relationship exists between contractor prequalification criteria and cost, time and quality performance of civil engineering project at p?1%. In spite of this, interconnectivity between these three variables is demonstrated by contractor prequalification criteria. Cohesion also exists between cost, time and quality performance of civil engineering project at p?5%. Therefore, criteria for contractor prequalification firmly bind cost, time and quality performance of civil engineering project. Also, the firmness of cost time and quality performance of civil engineering project depends of contractor prequalification criteria. Hence, client and representatives should take the cohesiveness of cost, time and quality performance into consideration when determining the choice of contractor prequalification criteria for civil engineering project.
