This work presents the application of the method of the Analytic Hierarchy Process (AHP) as tool of support to the Management of Industrial Projects. The focus of this study is the expansion project of the Alunorte industry, worldwide leader of alumina production. The success of industrial enterprises implementation such as the Alunorte project depends on the performance of the Engineering area of the Project, which is responsible for the conception and coordination of the several engineering projects integrating the global project. A direct relation exists between the effectiveness of the engineering contractors (designers) and the global performance of an industrial enterprise. Therefore, it is primordial to guarantee and to measure the quality of Engineering. The present research considers an evaluation of the engineering designers through a single index that evaluates the essential qualifications of an engineering project. The AHP method provided a basis for establishing the logical problem and generating results on quantitative and qualitative aspects. As a consequence, the index developed represents a tool for decision making process of engineering contracts practices and quality excellence achievement. Moreover, the analyses of a specific case study may contribute to the management of general industrial projects.
