The general statute for contracting in public administration in Colombia (Law 80 of 1983) establishes that state entities (Law 489 of 1988), except those that the law does not require more than one proposal, must select their contractors through: public tenders, invitations or any contractual modality, according to the legal regime applicable to the contract (Law 816 of 2003). In order to guarantee transparency in the bidding processes, have been proposed different types of formulas and even then, they sometimes end up favoring the same group of people. This article analyzes the impact of the bidder selection formula on road infrastructure projects in the Department of Valle del Cauca. For this purpose, contract specifications were available based on the digital platform of the Electronic Procurement Service SECOP. As a result, it was found that the most used formulas are the arithmetic mean and the geometric mean with official budget. It is clear that, despite the great variety of formulas, there is a high works simultaneously adjudicated to natural persons participating in different forms of association.
