Project data

Location: Thun, Switzerland

A subterranean parking ground for 300 vehicles in the city center of Thun.

  • 2 caverns (l = 80 m, h = 18 m, w = 20 m)
  • Gallery 140 m
  • Shaft Schlossberg, depth 19 m
  • Excavated material 51,000 m³
  • Interior work with reinforced concrete 14,000 m³

Requirements

  • Caverns and galleries in fair-faced concrete quality in very confined circumstances
  • Use of self-compacting concrete (SCC)
  • Transportation of the formwork carriage from one into the other cavern through small connecting gallery

The efficiency and the enormous expertise during the planning and execution of the PERI / MCE formwork concept have convinced us.

PERI solution

  • In cooperation with MCE Engineering, PERI plans and supplies modular-type formwork solutions with electrical drives and hydraulic lifting supports, movable on tracks, with dimensions suitable for a hydrostatic fresh concrete pressure with self-compacting concrete (SCC) and with the formlining in fair-faced concrete quality.
  • Through special extensions to the gallery formwork, caverns and connections branching off can be concreted in one pour.
  • Different PERI system components are used for further construction parts of the projects.
