This paper aims to evaluate mechanical equipment suppliers of an engineering organization in order to increase business competitiveness. To this end, a Multi-criteria Decision Aid - Constructivist (MCDA-C) methodology was used for addressing the following steps: i) Structuring; ii) Evaluation; iii) Recommendation. This has enabled the production of knowledge on the studied context, considering its important aspects, and the support in decision-making. The importance of this accomplishment is founded on the powerful tool left as a legacy to the involved parts (engineering organization and suppliers); the consequent improvements in the entire chain of Brazil's infrastructure; and the ennoblement of knowledge and the extrapolation of its theoretical-practical frontier in the Performance Evaluation area.
