Part 4.1 Scope and application of Section 4

This Section sets out the Deemed-to-Satisfy Provisions for footings and slabs.

Explanatory information

This Section specifies the requirements for the excavation and filling for the footing or slab together with the construction of various alternative concrete slab and footing configurations. The slab and footing configurations detailed in this Section are only suitable for the specified soil classifications. The requirements contained in the remainder of this Section are more general and may be applied to all slab and footing construction.

The requirements of this Section are to be read in conjunction with Part 6.2. The Part 6.2 subfloor ventilation requirements apply to the subfloor space of all suspended floors of a building or deck, including but not limited to, timber and steel-framed subfloors and suspended concrete slabs.

The application of this Section is subject to the following:

  1. The Governing Requirements of NCC 2022 Volume Two.
  2. Any conditions set out within the following Deemed-to-Satisfy Provisions of NCC Volume Two: H1D4(2), for footings and slabs.
  3. The State and Territory variations, additions and deletions contained in the Schedules to the ABCB Housing Provisions and NCC Volume Two.
