Innovazione di Processo: Uso dei Modelli Informativi per L’offerta Economicamente piu’ Vantaggiosa. Process Innovation: Use of Bim-Oriented Model for Most Economically Advantageous Tender.

The aim of this research is the definition of the criteria, the sub-criteria, the evaluation procedures, the methods and the formulas to allocate points for a Most Economically Advantageous Tender in order to perform the 2014/24/EU directive that is ensure compliance with the principles of transparency, non-discrimination and equal treatment, with a view to ensuring an objective comparison of the relative value of the tenders. To do that, four criteria categories were identified. The described method was applied for the editing of a tender documentation with the most economically convenient bid for an integrated contract on a definitive project. The project was realized following the BIM methodology, which means that was used an integrated design system. At the end of the evaluation of the offers, completeness indexes and consistency index of the offers were calculated. The proposed method limits litigations because the procedures of evaluation are clear, explicit, and objective. The high levels of congruency found contain binding offers for the companies that, therefore, cannot change anything from what they proposed during the tender.
