Building Information Modelling is rapidly changing the way construction projects are procured, designed, built and managed all along the life-cycle of a facility. New skills are required, and the project tackles an urgent need to 1) develop a transparent and harmonized competence matrix for BIM actors accross Europe, 2) standardize BIM missions and processes at EU scale, taking into account the international BIM developments already existing and 3) classify and harmonize BIM training curriculum and certification schemes. BIM4VET project proposal firstly aims at developing a European competence matrix for BIM actors and a BIM qualification maturity assessment method that will assess BIM actors collective and individual competences. Then, a decision-support system will be developed to allow BIM actors to find adapted training offer in the context of their needs, and of their lack of collective and individual competences, when working on a particular project. The project is carried out by three institutions already active in BIM research and training. Moreover an expert panel will be setup in order to cover most of the viewpoints related to this topic, at international level. This expert panel will be used for project results validation and for dissemination channel purpose. The methodology that will used relies on the application of DELPHI approach to make experts consensually converge on both the BIM expertise and the maturity assessment topics. The IT-based decision-making system will rely on an expert system and will be implemented using a tangible tabletop device, enabling collaborative work and assessment of competences. The impact of the project is primary the definition of a European BIM actor competence matrix, and the improvement of BIM training for construction practitioners needs, through the training centres already involved in BIM. The important implication of BuildingSmart is a guarantee for delivering this short/middle term impact. At longer term the project and its possible follow-up actions will contribute to enhance BIM actors' mobility in Europe and to the digital transition of the whole sector.
