Located on the Île de la Marne in Noisy-le-Grand, this project forms part of a new eco-district and involves the construction of 119 collective housing units (up to four storeys) using a hybrid steel, timber (75%), and concrete structure.
Following major water damage during the construction phase, the site was shut down in 2022. We were commissioned to carry out both the design and execution phases of 6 sets of building (42 housing units) in order to restore and reinforce the existing structure.
After nearly two years of exposure to moisture, the timber elements were in poor condition. Despite everything, we managed to preserve and rehabilitate it through a series of targeted interventions, saving nearly 330 m³ of timber.
Once the prefabricated timber panels were opened and the damaged insulation removed, structural reinforcements were implemented: doubling of timber studs in the façades, strengthening of load-bearing joints, and reinforcement of tension brackets.
Numerous site visits were conducted to assess the damage and define case-by-case repair strategies.
