Supermontparnasse Tower

​Il s'agit de la rénovation thermique d'un immeuble de grande hauteur, construit dans les années 60.
Cette rénovation de part les performances obtenues, la technicité et le contexte (copropriété de 270 logements en milieu occupé) est citée en exemple par la ville de Paris et l'APC.

Architecture PELEGRIN created the digital model of the existing building then enriched it all along the project with technical solutions selected by the team and the owner.
BIM was a communication tool and live decision tool for the 270 co-owners. It allowed "quick decisions" when decision timescales for condominiums is usually terribly long and the multiplicity of statuses (living onsite owners and landlords, retired and firts-time buyers, and more...) don't make things easy. During presentations in front of the co-owners, each inhabitant of the building could comprehend the project in its globality and visualize the consequences for their own apartment. Without BIM, the decision to vote the project would have required one year or even longer.
All the design team (architects, engineers, etc...) used the same digital model.
For the companies, BIM facilitated the construction phase in an occupied site: marked windows (what choices, what color) but also the coordinates of each inhabitant to make each intervention easier and ensure as low nuisance as possible.
