The enormous redevelopment of the site around Broadcasting House is situated between the Bakerloo and Victoria underground lines and the tube trains are clearly audible in all the buildings. Therefore, CDM was asked to install floating floors using the CDM-QDECK system.

To protect the BBC W1 Technical Boxes from structure-borne noise each one was built off a concrete floating floor.

The construction of the floating floors depended on the location within the building: in the basement the floors were 125 mm concrete on 100 mm void supported by bearings with a natural frequency of <8Hz.

On the ground floor the floors were 90 mm concrete on 100 mm void; the 2nd floor was 90 mm concrete on 75 mm void and the 3rd and 4th floors 90 mm concrete on 50 mm void.
