Selection of Contractors for Middle-Sized Projects in Turkey

In the last decade, there has been a trend rising towards the improvement of the methods for effective contractor evaluation. Governments may have been utilizing these kind of studies during legislation and legal regulations on procurement. To achieve the best value for money, the tender evaluation should consider not only price competitiveness, but also compliance with users’ requirements, reliability of performance, capabilities and experience, qualitative superiority, and whole-life costs. Turkish public authorities arise the need for proper contractor selection approach including factors other than price. A contractor selection model is structured to cover non-price attributes together with the bid price. The concern of the model is the public authorities, who want and need to consider the factors other than price during contractor evaluation process of middle-size and semi-complex projects. The model is tested by a hypothetical scenario which evaluates four contractor candidates. The results show that the model provides a guide for the public client to reward experienced, capable and qualified candidate contractors, and to eliminate incompetent, inexperienced, or underfinanced contractors for the success and quality of works.
