PROJECT DESCRIPTION AND CHARACTERISTICS
First major shopping center in French-speaking Switzerland, the Balexert Shopping Center was inaugurated in 1971 and converted for the first time during the years 1990 to 2000. The whole complex offers a surface of 134,700 m², on two semi-subterranean levels of parking lot and two floors above the ground floor.
The project of westward extension, spans over the Meyrin road and offers 7,600 m² of additional commercial area on two levels and 840m² of offices on the roof level. The structural report of the extension was executed by the design offices T ingénierie & ZS ingénieurs civils.
Conversion and connection to the existing building were carried out step by step, with the shops remaining in service. The solution of a steel-concrete composite structure with a 17m span was chosen to create the new slabs. The creation of the roof level offices required demolition of the existing roof in order to recreate a floor about 1m above the existing level and thus increase the ceiling height.
