COOP Rolle

Short description

Construction of multifunctional buildings in the center of Rolle (Vaud), namely:
- 59 rental housing
- Large administrative and commercial areas (COOP)
- a health center (CMS)
- Underground private / public parking on 3 levels of basement (288 places)

The project

For the construction of the 3 basement levels Implenia Special Foundations has created diaphragm wall in very complicated soils (very fluid silts), with a very active groundwater. The site situation in the center of Rolle with existing buildings nearby was also one of the major challenges of this project.

Services in detail

  • 6000 m2 of diaphragm wall in 800mm / 600 mm depth of 18 to 30 m, 400 m2 of secant piles diameter 1200 mm deep 30 m
  • Foundations: 112 piles of foundations drilled / cased diameter 800mm / 1000mm / 1200mm 40m deep
  • Tubular shoring, different diameters, for a total of 650 tons

Challenges

Very complex soil for diaphragm wall, underground water very active and located 50 cm from the surface, location of the site in the city center, limitation of settlements on the existing building nearby
