Assessment of Construction Project Contractor Selection Success Factors considering Their Interconnections

Abstract

Clients frequently utilize tendering to select contractors in the building business. The goal of this research is to identify, assess, and rank the critical elements in evaluating contact bids for the best-value procurement technique. There is a need to better assess the importance of factors in evaluation of tenders using their linkages between them. It differs from previous studies in considering the connections between these factors, facilitating a robust ranking and tendering evaluation. This study is unique in that it is the first to use an analytical network process (ANP) model to rank evaluation elements while taking into account their interdependencies to the best of authors’ knowledge. This study included a literature review, a survey of construction industry specialists, and the application of the ANP as a ranking method for the variables. According to our research, there are 31 criteria that are critical to the success and performance of construction projects. Technical, financial, and qualification variables are divided into three groups, with the ANP model indicating that financial aspects are the most relevant. The findings of the study demonstrated that financial stability was ranked first, followed by offered price, proposed delivery date, experience with similar projects, past history, qualifications of engineers and technical staff, warranty and after sales services. The last five factors included level of innovation, use of new technologies, staff training plans, environmental considerations, and the number of liquid assets. When evaluating their interdependencies and the effects they have on other factors, the ANP ranking revealed that several elements previously thought to be inconsequential are in fact significant.
