Betydelig infrastrukturoppgradering

The Les Rayes public car park, commissioned by the municipality of Collonge-Bellerive, is located on Chemin des Rayes at the exit of the old village centre of Vésenaz in Switzerland. Built on municipal land in the eastern part of the village, this project brings significant infrastructural enhancements to the area.

Forsterket betongstruktur i grøft

Construction involved creating a reinforced concrete structure within an excavation pit made of Berlin walls, partially submerged in groundwater that was temporarily lowered during the building phase. The structure rests on a common floor slab, with intermediate columns made of reinforced concrete providing support to the floor slabs. The roof, also a reinforced concrete slab, is designed to hold various equipment and loads specified in the construction plan. The central core features a steel structure with large glass surfaces, housing a panoramic lift, a metal staircase, and connecting bridges. The building’s volumes are carefully designed to fit the local topography and make its functions easily recognizable.

201 parkeringsplasser og fasiliteter

The facility offers 201 parking spaces and includes the installation of an 18,000-volt low/medium-voltage transformer station for Geneva's public utility company. Additional features include a sorting facility with appropriate containers, a multi-purpose area for various uses, and a children's playground. The central core serves as the main pedestrian access point and is a visually striking cylindrical glass and metal structure that contrasts with the other project elements. To blend in with the surrounding environment, the above-ground access's concrete walls are clad in cedar wood.

Avansert sikkerhet og landskap

The car park also includes a control room equipped with advanced security and operational systems, including video surveillance, sprinkler systems, CO2 detection, public address systems, emergency lighting, mechanical ventilation, and toll collection. The public areas on the building's surface are thoughtfully landscaped and generously planted with trees, making the roof a comfortable and appealing space for public use. The project, which began in June 2003 and was completed by June 2004, was designed by Pierre Ambrosetti & Olivier Vallat Architectes.
