New construction of a mixed-use office and residential building
Location
Fröbelstraße 24, Köln
Construction year2026
Project descriptionSteel fiber reinforced concrete was used for the foundation slab of a new residential and office building in Cologne.
Optimisation with SFRC
- Accelerated construction process through the use of steel fiber reinforced concrete
- Optimized slab thickness, reduced by 20–40 cm compared to the original design
- A key economic advantage was achieved by lowering the cost of the secant pile wall, thanks to the reduced slab thickness
- Reinforcement for crack width control was reduced by more than half → resulting in efficient execution and cost savings
