NATIONAL CONSTRUCTION CODE BUILDING CODE OF AUSTRALIA 2019 & DISABILITY (ACCESS TO PREMISES – BUILDINGS ) STANDARDS

The NCC BCA is a performance based code. Compliance can be met by either meeting the deemed to satisfy provisions, by a performance solution or by a combination of both. This section of the report sets out so each deemed to satisfy clause of the NCC BCA. Assessment comments are provided against each clause. Where performance solutions are applicable additional reports and assessments will be required.

Performance solutions can only be considered if they are undertaken by a suitably qualified and experienced professional using one of the prescribed methodologies set out in the NCC BCA. Where performance solutions are applicable supporting CV’s and evidence of qualifications will be required.

APPENDIX B - Sanitary Facilities

Number of facilities is calculated based on the population under BCA clause D1.13.

The BCA allows a PWD facility to count as one male and female facility. This concession has been taken into account in the figures below so the number of facilities have been reduced accordingly.

At least one ambulant facility is required in each bank of toilets that contains a PWD in addition to conventional sanitary facilities. There is no requirement where the bank only contains a PWD, or if it contains only conventional facilities.

Ambulant facilities are required at each bank of facilities where a PWD WC is provided.
