BNP Paribas Headquarters

DYWIDAG-Interspan has been commissioned to design and post-tension the slabs of the new headquarters of BNP Paribas in Brussels. The huge construction site is located in the city center of the European Capital, Brussels. Initially designed as a unbonded monostrand slab PT system, our in-house design team convinced the project team to change the entire structure to a bonded PT system. The advantages of flexibility, durability and the limitation of deflection are only some advantages driven by this technology.

Additionally, big multistrand tendons are foreseen in beams and an architectonical Arche at the entrance.

DYWIDAG-Interspan value-add:

• Design change from unbonded to bonded PT
• A decrease in slab thickness
• Special chair system to avoid drillings in tendons
