A Contractor-Centric Construction Performance Model Using Non-Price Measures

Selecting a better performing contractor at the procurement stage is crucial in achieving a successful outcome for a construction project. The construction industry lacks a systematic and purpose driven method to assess performance of contractors using objective metrics. There are many approaches to measuring construction performance, but most are complicated and have high dependency on data that is difficult to attain. This paper aims to create a model for evaluating construction contractors’ performance based on directly attributable measures that are quantitative and easy to gather. This makes such a model more attractive and easier to use. Initially, a detailed literature review revealed different categories of measures of performance (MoP) and corresponding critical measures of performance (CMoP). Through a series of Delphi-based expert forums, the set of measures were fine-tuned and shortlisted. Fuzzy analytic hierarchy process-based comparisons were then used for developing a contractors’ performance model to quantify their level of performance based on a limited set of organisation-specific and project-specific measures. The results indicate a shift from traditional measures and a higher preference towards non-price measures. The performance model can be further developed to systematically rank the prospective contractors at the procurement stage based on seven non-price measures.
