Construction of a mixed-use office and residential building
Location
Fröbelstraße 24, Köln
Construction year2024 — 2025
Project descriptionCombined reinforcement for the foundation slabs for a mixed-use office and residential building in Cologne.
Optimisation with SFRC
- The construction process was sped up due to the use of combined reinforcement
- Optimisation/reduction of slab thickness by 20 – 40 cm compared to the original solution
- The reduction in costs for the secant bored pile wall (due to the reduced slab thickness) resulted in a major economic benefit
- Reduction of the crack width-limiting reinforcement by more than half -> Optimal constructability/economic aspect
Slab thickness
50 - 120cm
