PROJECT DESCRIPTION AND CHARACTERISTICS
The project consists of the burial of the existing customs road and is A part of the project Aile_EST (construction of a new terminal “Big Carriers”) of Geneva International Airport. This work will also be the foundation of the future Aile_EST terminal. The work resulted in the creation of:
- technical gallery of 250ml,
- two 250ml traffic lanes,
- technical premises zone (approximately 1,500m²) dedicated to the future terminal,
- 2,500m² storage platform above the traffic lanes,
The main constraints of the project were:
- Maintenance of full airport operations at all times despite the small size of the site,
- Maintenance of traffic on the existing customs road during the execution of the works,
- Maintenance of existing networks in underground technical galleries
- Earthmoving with the use of geothermal probes.
Technical characteristics:
- Molded walls 60cm and 80cm thick (8,000m²),
- Drilled piles 60cm and 80cm of diameter (2,000 ml), static tests of piles,
- Concrete (12,500 m³), reinforcement (1,500 tons),
- Provisional supports in nailed walls (1,400m²), Berlin walls (1,600m²),
- Earthmoving (45,000 m³),
- Tarmac concrete (6,500 m²), bituminous coatings (6,200 m²),
- Installation of drainage and drainage networks (2,500 ml),
- Demolition works.
