Project description:
In the place called Obri Gaara in Leuk, a terraced house is being built with 2 apartment buildings with a total of 14 residential units and 16 garages. The excavation was carried out with the help of a 3D structure on the excavator. At the same time, the rock was excavated with a hydraulic pick hammer. All slopes were secured with shotcrete, in some cases up to a height of 10 meters. The surrounding walls and the ceilings of the basement are made of in-situ concrete. The walls of the first and second buildings are made of concrete and partly of brick. All ceilings are made of in-situ concrete. Due to the hillside location, the apartment building enjoys a fantastic view!
Requirements:
- Very short construction time
- Excavation with slope stabilization
- Very tight space conditions
- Terrace ceilings all made of exposed concrete
- Complex buildings
