Rua do Polo Sul
Thanks to a bespoke CDM-FLOAT solution offices located just on top of the car park and next to the street don’t suffer from structural noise problems anymore.
Vodafone-Portugal transferred its new head-quarter building to Parque das Nações Zone (world exposition site – Expo98 Lisbon). The building comprises two blocks with a street running between them and car park access via a tunnel.
Structural noise was a problem in the offices located around the street and the car park entrance; especially below the street slab. Additional difficulty was caused by the sloping of the different floating slabs and the significant shear loads.
A CDM-FLOAT floating floor system with a resonance frequency of 12-13Hz was installed across the whole of the street slab using conical pads in the sloping zones and rectangular pads in the straight zone.
