KEY
W Only the separating wall requires pre-completion sound testing.
1 Lightweight steel and timber frame walls may be constructed above in-situ poured concrete floors. The lightweight walls built directly off the concrete floors may be registerd as Robust Details provided:
  • they meet all other requirements of the Robust Details, including flanking constructions
  • the principles of the raft foundation junction are followed. As such, the concrete of the floor must have a mass of 365 kg/m2 (min), and a floating floor treatment must be provided.
Walls constructed to the soffit of in-situ poured concrete floors can not be registered as Robust Details and may be subject to pre-completion sound testing.
