PROJECT DESCRIPTION AND CHARACTERISTICS
Located in the Servette district in the center of Geneva, the social housing building consists of five floors above the ground level plus attic and two underground levels. It consists of 34 apartments of 3 to 5 rooms and offers 54 parking spaces on two underground levels.
The structure rests partly on the existing 2-level underground parking, which aboveground level was demolished in order to complete the housing project. A thick transitional slab has been installed a ground level in order to solve the issue of transmistting of the vertical forces from the bearing elements of the new building to the existing bearing elements of the parking lot. The Cécilia room, adjacent to the new building, required an underpinning of its foundations to the right of its gable facade.

PROJECT DESCRIPTION AND CHARACTERISTICS
After the planned demolition of the Vernets barracks in the Canton of Geneva, the canton decided, in agreement with the Federal Department of Defence, Civil Protection and Sport, to start the conversion of the Arsenal building in Meyrin-Mategnin. Since 2007, this building has been partly leased by ArmaSuisse and is currently used by AMBA CENTRO engagement center. After its conversion, this building should be able to receive two companies of 150 men, type SUBVENIO, or a company of 300 men.
The current building includes a ground floor and a floor accessible from the back of the building. Its structure is made of reinforced concrete frames windbraced by the facades. The slabs are prefabricated with windbraced concrete beams and hollow concrete blocks. An alternative consisting of demolishing and reconstructing a new building was proposed and accepted in place of the heavy conversion with creation of an additional floor proposed in the feasibility study.
