Ascertaining the impact of contractors pre-qualification criteria on project success criteria

Abstract

Purpose The selection of a suitable contractor for a project has a significant impact on project success. In order to avoid the selection of an incapable contractor, the capabilities of contractors must be assessed prior to tendering through pre-qualification. However, the pre-qualification process is characterized by partiality and ambiguity. In view of this, numerous models have been developed to solve the pre-qualification problems. Prior to the development of such models, it is very important to assess how the pre-qualification criteria impact project success criteria so as to aid in the selection of pre-qualification criteria while considering the project and client’s objectives. Therefore, the purpose of this paper is to ascertain the relationship between contractors’ pre-qualification criteria and project success criteria. Design/methodology/approach The study utilized explanatory research design in testing 35 hypotheses. The views of 121 practising quantity surveyors were solicited using a structured questionnaire and analyzed using the partial least square structural equation modeling to validate the hypothesis. Findings In all, 13 of the 35 hypotheses were not supported. The findings indicated a clear relationship between contractors’ pre-qualification and project success. Practical implications Therefore, it is evident that the practice of lowest evaluate bidder is not adequate for providing a satisfactory project outcome. It is, therefore, suggested that more emphasis should be placed on contractor’s technical abilities, health and safety and management capabilities as they have proven to have a significant correlation with the project success. Originality/value This study provides insights to the how various pre-qualification criteria can impact the project success criteria and further contributes to the symbiotic that exist in the literature on pre-qualification and project success.
