Changes to the National Construction Code 2016
All changes to the National Construction Code for the 2 Building Codes and Plumbing Code that form part of the National Construction Code Series (NCC) 2016 will be implemented as of 1 May 2016.
Copies of the NCC are available free online via the ABCB website (www.abcb.gov.au) which was introduced to reduce costs to the industry. However, for those who would prefer to work with a hard copy of the NCC can do so by contacting Master Builders on (03) 9411 4555.
In the past the NCC was amended annually to reflect required changes to improve standards of construction. The 2016 NCC will be in place for three years before they are subject to amendments, which will allow the industry to embrace the implemented changes and provide a degree of continuity of the performance-based standards for building construction.
There have been a number of changes that are clearly described within the list of amendment tables included at the rear of each Building Code and the Plumbing Code.
The following brief summarises a number of the changes within the Building Code of Australia 2016 (Volume 1):
A number of definitions and Australian Standards within the Building Code have changed and are now self-explanatory.
AS5146 Reinforced Autoclaved Aerated Concrete: structure has been included as a referenced document.
A new provision has been included to allow the use of fire protected timber in Class 2, 3 and 5 buildings that do not exceed a maximum effective height of 25m, sprinkler- protected and comply with the remaining provisions of C1.13 and Section E.
Clause D2.13 allows a concession for deviations in finished stair dimensions as a result of atmospheric moisture changes.
Section E includes a new note that provides clarity in Class 5, 6, 7b, 8 or 9b buildings when smoke hazard management systems are applicable, and also allows a concession for smoke detector requirements in sprinkler protected areas of a Class 9a health care building to reduce spurious signals.
A new sub-clause has been added to exempt ward areas from needing separate sanitary facilities for males and females.
A new section H3 has been included within the Building Code which contains provisions applicable for the construction of farm buildings and farm sheds.
The Victorian Appendix includes:
A new clause for the requirement to provide sprinkler protection to balconies in a Class 2, 3, 4, 9a and 9c buildings
The concession for buildings using fire-protected building elements has been excluded from the concession for Class 2 and Class 3 buildings
The following brief summarises a number of the changes within the Building Code of Australia 2016 (Volume 2)
A number of definitions and Australian Standards within the Building Code have changed and are self-explanatory.
The 2015 edition of AS 1670 Part 1 'Fire detection, warning, control and intercom systems - System design, installation and commissioning — Fire' has been referenced to allow for the installation of an alarm that is suitable in a Class 10a private garage
The 2013 edition of AS 1657 'Fixed platforms, walkways, stairways and ladders — Design, construction and installation' is no longer a referenced document and has been deleted.
A new Verification Method has been inserted to verify compliance with the Performance Requirement P2.1.1 (a)(iii). V2.1.2 is a means for verifying the structural robustness of a building.
A number of changes have been included within Part 3.5 for the design and overflow provisions of roof drainage designs.
There has been a new clause inserted within Part 3.7 that nominates the fire separation requirements where parts of a Class 10a private garage is constructed above or below a another dwelling which is not specifically appurtenant to that garage.
Clarity has been included in Part 3.8 that confirms a washbasin does not need to be associated with a closet pan.
Part 3.8 also incorporates further amendments that incorporate, clarify and explain the means of calculating light and ventilation requirements.
Part 3.9 incorporates new design requirements for safe movement and access within a Class 1 and 10 buildings:
Stairways to be designed to allow for forces in accordance to AS 1170
The minimum height of a threshold has been increased from an adjoining surface before it is considered that a stairway is required
There is a new inclusion for the deemed to satisfy provisions requirements for ramps
An allowance for finished stair case dimensions has been included considering movement of materials due to atmospheric moisture changes.
Considering AS 1657 has been removed as a referenced document there are new deemed to satisfy requirements for stairways serving non habitable rooms.
References made in Part 3.10 for timber windows in a wind classification of N3 or C1 to comply with AS 1288 have been deleted. This aligns with the intent that timber windows are to be constructed and installed to comply with AS 2047.
Part 3.11 has been updated to reference requirements for:
Nail-plated timber trusses
Post installed and cast in fastenings to concrete
It is advised that all the changes for National Construction Code Series (NCC) 2016 are included in the amendment tables of each individual Building Code; this is a summary of some of the key changes only.
