Abstract
Purpose
The studies on contractor prequalification focus more on the review of models and algorithms rather than review of the criteria for contractor prequalification. However, the basis of every prequalification model primarily relates to the measurement and judgement of prospective contractors based on a set of decision criteria. This paper aims to address the gap by reviewing academic papers on contractor prequalification criteria.
Design/methodology/approach
A desktop search was conducted under the “T/A/K (title/abstract/keyword)” field of the Scopus search engine. A total of 49 papers were initially identified; however, only peer reviewed journals were selected for the study; therefore, a sample of 36 was subsequently used. Further filtering was done in which 26 papers were found valid for further analysis as it was realized that, not all the identified papers presented empirical arguments about the issue of contractor pre-qualification criteria. The selected 26 papers were subjected to content analysis to identify the key contractor pre-qualification criteria.
Findings
A total of 41 criteria were identified which were subsequently classified into six main categories, namely, technical considerations, management considerations, financial considerations, reputation considerations, general experience considerations and health, safety and environmental considerations. There was an indication that, the involvement of health, safety and environmental considerations in contractor prequalification proceedings is limited.
Research limitations/implications
The major limitation of this research was the limited number of papers selected for further analysis based on the Scopus search engine. The identified criteria serve as a basis for further empirical studies on contractor prequalification criteria.
Practical implications
The outcome of this study broadens the understanding of practitioners and researchers on the various criteria for contractor prequalification.
Originality/value
By critically reviewing available literature on contractor prequalification, the study sets the tone for further empirical studies on contractor prequalification.

Abstract
Purpose
Works procurement performance is critical to successful project delivery. However, early supplier involvement (ESI) has been touted in other industries to impact procurement performance positively. Works procurement has been attracting significant attention from major players due to poor performance characterized by poor performance, budget overruns and incompetence. Hence, the purpose of this study was to assess the impact of ESI on public works procurement performance.
Design/methodology/approach
Based on a thorough review of the literature for a pilot survey, the main questionnaires were administered to 103 public procurement officers. To assess the impact of ESI on public works procurement performance, three constructs that served as factors for implementing ESI and five that measure works procurement performance were validated using partial least square structural equation modelling (PLS-SEM).
Findings
The outcome of this study shows a significant positive impact of ESI on works procurement performance. This included communication, trust and supplier capabilities. The study further showed that even though cost, schedule, quality, health and safety are essential, sustainability measures are also crucial for work procurement.
Research limitations/implications
The results of this study could help firms make better decisions regarding public works procurement by encouraging ESI. This will likely significantly impact the successful project delivery and preservation of sustainability and efficiency objectives.
Originality/value
The application of PLS-SEM analysis in this study provides insights into how ESI can impact the procurement of public works in Ghana.

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.
