In Toulouse, a student residence renovated at high speed thanks to off-site construction
The execution speed is impressive. In just ten minutes, a brand new panel is affixed and fixed to the facade of the brick building integrated in the mid-1960s. It will take only four months, half the time of a conventional construction process. , to provide new facades for the 254 housing units of the student residence of the National Veterinary School of Toulouse. To achieve this, Bourdarios (construction manager) and its co-contractor GTM Bâtiment, both subsidiaries of Vinci Construction, have developed an innovative process (called Rehaskeen) for off-site construction.
The panels are prefabricated to measure in the workshop and delivered to the site with the insulation, the final facing, the joinery and the shutters already integrated. ” This avoids installing scaffolding. We also need to drill far fewer holes to install fasteners. Off-site construction also reduces nuisance for tenants and they do not need to leave the accommodation during the work », met in preview Fabrice Laurent, director of activities at Vinci Construction.
In addition to the facades, the rehabilitation program of the student residence which will involve a major overhaul of the buildings for 9.6 million euros of investment. ” The program provides for the improvement of the energy sobriety of the building envelope, the implementation of high-performance equipment and the production of renewable energies by production of solar hot water, which which will in particular reduce primary energy consumption by 75%. After work, the building consumed less than 60 kWh in final energy per m2 and per year “, specifies the Group of the Chalets.

A booming process
The rehabilitation project led by the Groupe des Chalets is one of the 10 winners of the Massireno national call for projects launched by the Ministry of Ecological Transition, as part of the France Relance plan, for the massification of the exemplary renovation of the rental stock. social. In addition to the renovation of the student residence of the National Veterinary School, a second program has been labeled Massireno in Occitanie. This is Cité rose, a housing complex built in Ramonville in the 1960s and managed by the Groupe des Chalets. ” Off-site construction lends itself well to the renovation of student residences, social housing and more generally buildings with framed facades », adds Fabrice Laurent.
In addition to the two renovation programs implemented in Toulouse, the two Vinci construction subsidiaries already have three off-site construction projects in the pipeline in the Paris region where they have a 2,000 m2 workshop to produce prefabricated panels. before their integration on the worksites. The dynamism of the Toulouse market could lead to the establishment of a new workshop in Haute-Garonne. The French construction giants are not the only ones trying to capture this new market. New players have emerged in this niche like the Toulouse ModuleM. Faced with this new competition, Vinci construction intends to stand out by offering both the manufacture of the panels and their installation on the site.
