Based on the consistent background and knowledge that the University of Minho (UMinho) has in ‘Building Information Modelling’, a practical roadmap towards the full BIM digitalization of the infrastructure management process has been recently set-up. After an initial diagnosis stage, the process of BIM implementation formally involves four stages related to the definition of modelling rules/requisites (Stage 1), the preparation of prototype buildings to test the concepts (Stage 2), the enlargement/ generalization of the process towards the Campuses of the UMinho (Stage 3) and a final stage of consolidation and improvements (Stage 4). This paper briefly describes the implementation of the two first steps, with a particular emphasis to the description of the two selected case studies.
