The new working methods focused on BIM (Building Information Modeling and / or Management) require radical changes in all the practices of all stakeholders of an architectural project , and collaborative involvement of all stakeholders to make the best in each business the benefit of this new methodology. It is also a philosophy, a way of working and a tool to enrich and maintain throughout the building life cycle. Like all actors are called to work together , it makes sense to train together and to offer a tool where they can test in common process and negotiate the best turn of BIM . Developed by a team of 8 European partners, the project aims to share this culture and its impact on all stakeholders of the building, providing them with a learning platform (LMS = Learning Management System), under as a hybrid former (blended learning) where mix-face and distance modalities. For participants (1000 people referred), the impact is clearly the concretization of a desire to contribute to the recent revolution in professional practices in the field of construction, revolution embodied by BIM. For training organizations, universities or professional, the creation of the LMS will be an important innovation in a rapidly changing technology. The needs in training and collaborative and innovative angle chosen by the BIM GAME make a tool expected by many industry players. The expected impact is economic (saving time, reducing costs), environmental and societal. This device is designed to be handled by the BIM trainers, with all the possibilities offered by the LMS. Each trainer will be responsible for the organization of learning, modulating content , scenarios and assigning roles to each trainee . Groups targeted training correspond to future players of a construction project : architect, engineer , contractor, driver operation , construction economist , public or private client, head of industrial, operator , etc ... the LMS offering digital models and realistic business scenarios , will focus on the effective collaboration between teams and will propose the nearest working model possible to the actual conditions. An evaluation system based on feedback from user experiences will be implemented : trainers, trainees , professionals, etc ... . This is to develop qualitative studies based on a compilation of data from observations and field interviews ( Beta - tests). The European project will enable a broad assessment of the platform given the different practices. For these reasons , the involvement of developers , partners , cutting the project in phases and the work schedule will be paramount .There can be found: 1. At the center, various new construction projects or renovations with different numerical models.These projects present a great diversity of buildings typologies, constructive types, quality achievements, and will include several types of models (architectural, structural ….).Some projects may register in specific issues, leading a specific use of these models, linked with constraint or outsourced software. 2. Defined roles with different level of responsibilities which involve the whole building trade, directly or indirectly. 3. More or less constrained scenarios depending on the skill level of trainees who are involved in this process. Scenarios for each type of actors (customized avatars) but also a type of process related to a particular project. 4. A communication system via a collaborative platform. This platform will provide the operational interface for exchanges between the players; in order to reach the final conclusion of the scenario depending on the operational level of the players and the type of project. 5. An assessment system of the collaborative process will allow the analysis of the abilities to participate and understand the issues of any roles in the chosen BIM process. This tool can be used as part of a classical face training or at a distance training. Modules of external training in the use of the tool will prepare each actor to play its role and understand the various technicalities related to the role that will be vested.
