Abstract

Normally, the selection of a project team is based on Weighting Rating Calculating (WRC) and often relies on only one factor; the cost factor. WRC is a method that allows for assessing multiple factors easily but the bidders’ differences may not be highlighted, since factors are weighted independently of the attributes. A more recent concept, which is based on WRC, is Best Value Selection (BVS). BVS is a method where the best value score is calculated as the bid price divided by the qualification score. Choosing By Advantage (CBA) is a multiple-criteria decision-making method based on advantages of alternatives. Advantages are compared in order to decide the importance of them. We argue that CBA provides further benefits for helping public clients to differentiate between bidders. A case was constructed, based on the tendering procedure of the project Mission Hall, to exemplify the differences of the three methods for bidder selection in the context of public tendering requirements. This paper presents the analysis and discusses the results of the simulated case.
