The municipality of Broc is planning the construction of two new buildings that will accommodate new kindergarten and primary school classrooms, a space dedicated to after-school care, a multipurpose hall, as well as an underground parking facility. The entire project is located in the immediate vicinity of the existing primary school and partly extends above the existing civil protection shelter.

The project consists of three entities. The first corresponds to the underground parking, which includes 37 parking spaces, an extension of the civil protection shelter and an access ramp. All these structures are constructed in reinforced concrete.

The second entity concerns the school building, which groups the classrooms and is directly supported by the structure of the new parking. This building comprises two levels built using a timber-concrete composite structure. The structural system consists of columns, beams and joists topped by a concrete slab, while the stability of the building is ensured by a reinforced concrete elevator core and by a shear wall designed to resist lateral forces due to wind or seismic action.

The third entity is the pavilion accommodating the after-school facility and the multipurpose hall. This single-storey building rests partly on the civil protection shelter and partly on the new parking structure. Its load-bearing structure is entirely made of timber. The stability is ensured by a system combining concrete and cross-laminated timber (CLT) shear walls, complemented by fixed timber columns providing the necessary bracing.
