NCC RESOURCE TOOLKIT

A building, plumbing or drainage solution will comply with the NCC if it satisfies the Performance Requirements…

which are the legal requirements of the NCC.

A ‘TOOLKIT’ – DESIGNED FOR PRACTITIONERS, ADMINISTRATORS, STUDENTS AND EDUCATORS IN THE BUILDING SECTOR

To support the National Construction Code (NCC) and assist all those working in the construction industry, the Australian Building Codes Board (ABCB) develops an extensive range of resource materials, events and information services.

All materials described in this toolkit, and more are available to you free from the ABCB website, www.abcb.gov.au.

CONSTRUCTING A BETTER, SAFER BUILT ENVIRONMENT

The ABCB is a Council of Australian Governments (COAG) Standards writing body that is responsible for the NCC. The NCC comprises the Building Code of Australia (BCA), Volume One and Two; and the Plumbing Code of Australia (PCA), as Volume Three. The ABCB’s mission is to address issues of safety and health, amenity and sustainability in the design, construction and performance of buildings whilst also being a regulatory reform vehicle for COAG.

In 2015, the NCC was made freely available online ensuring all those involved in the Australian construction industry can access this important information. This helps ensure the continued construction of better, safer and more sustainable buildings.

A 2012 report by the Centre for International Economics found that building regulatory reforms implemented progressively over the last 20 years are delivering $1.1 billion per annum in benefits, with an additional $1.1 billion per annum in potential benefits yet to be realised. Many of the materials detailed in this toolkit will assist with the realisation of these benefits through a better understanding of the NCC as a performance-based code.

The ABCB operates under the Inter-Government Agreement endorsed by the Commonwealth, States and Territories, which sets out its mission, objectives and functions.

A NATIONALLY CONSISTENT CONSTRUCTION CODE

The NCC aims to incorporate all on-site construction requirements into a single performance-based code. A performance-based code provides flexibility to meet the Performance Requirements through using the Deemed-to-Satisfy Provisions or by developing Performance Solutions based on existing or new and innovative building, plumbing and drainage products, systems and designs.

All States and Territories adopt the NCC for all new building works and plumbing installations; however it is important to check for possible local variations. This model ensures a high degree of consistency between the States and Territories.

The NCC comprises of:

NCC Volume One – Containing the requirements for multi-residential, commercial, industrial and public buildings.

NCC Volume Two – Containing the requirements for housing.

NCC Volume Three – Containing the plumbing and drainage requirements for all buildings.

In addition to the mandatory Performance Requirements, each Volume contains Verification Methods, Deemed-to-Satisfy Provisions and referenced documents to assist practitioners in demonstrating compliance.

THE NCC: A PERFORMANCE-BASED CODE

The NCC is a performance-based code. It contains Performance Requirements for the construction of buildings and there plumbing and drainage systems. The Performance Requirements are the only legal requirements of the NCC and set the minimum level those buildings, building elements, and plumbing and drainage systems must meet.

The benefit a performance-based NCC is the focus on the outcome as opposed to the solution. It provides practitioners with a choice of compliance pathways, through a Deemed-to-Satisfy Solution or a Performance Solution. A Deemed-to-Satisfy Solution, which is not mandatory, uses the Deemed-to-Satisfy Provisions from the NCC. A Performance Solution provides flexibility in determining the most suitable means for demonstrating compliance directly with the Performance Requirements.

Developing Performance SolutionsTo assist in undertaking Performance Solutions, the ABCB has produce a range of supporting materials. These include YouTube clips, the performance guidance document and infographics outlining this process and assist practitioners in developing and approving Performance Solutions.

UNDERSTANDING

THE NCC

HOW TO COMPLY WITH THE NCC

The National Construction Code (NCC) is Australia’s performance-based building and plumbing code. It sets

the minimum technical requirements for the construction of new buildings (and new building work in existing

buildings). This document gives an overview of options available to demonstrate compliance with the NCC.

This information is useful for all NCC users.

The NCC is a performance-based code. This means that a building, plumbing or drainage solution will comply

with the NCC if it satisfies the relevant Performance Requirements. Compliance with the NCC is achieved by

complying with:

1. The General Requirements1 of the NCC, and

2. The relevant Performance Requirements.

The General Requirements are a set of governing rules outlining how the NCC must be used and the process that

must be followed.

The Performance Requirements prescribe the minimum necessary requirements for buildings, building elements,

and plumbing and drainage systems. They must be met to demonstrate compliance with the NCC.

Three options are available to demonstrate compliance with the Performance Requirements.

The information in this document is intended to be used as guidance material only, and is in no way a substitute for the NCC and related State and Territory legislation. The information

in this publication is provided on the basis that all persons accessing the information undertake responsibility for assessing the relevance and accuracy of the information to their

particular circumstances.

UNDERSTANDING THE NCC

BUILDING CLASSIFICATIONS

The National Construction Code (NCC) sets out the minimum technical requirements for new buildings (and new building

work in existing buildings) in Australia. In doing so, it groups buildings1 by their function and use. These groups are assigned

a classification which is then how buildings are referred to throughout the NCC. This information is crucial for all NCC users.

The following is a general representation of the building classifications in the NCC. It is based on a national perspective and

does not address any State or Territory variations2.

The building classifications are labelled “Class 1”

through to “Class 10”. Some classifications also have sub

classifications, referred to by a letter after the number

(e.g. Class 1a).

Class 2 to 9 buildings are mostly covered by Volume

One of the NCC and Class 1 and 10 buildings are mostly

covered by Volume Two of the NCC. Volume Three of the

NCC, the Plumbing Code of Australia, refers to all building

classifications.

A building may have parts that have different uses. In most

cases, each of these parts must be classified separately.

A building (or part of a building) may also have more than

one use and may be assigned more than one classification.

BUILDING CLASSIFICATIONS

NCC Volume One (Part A3)

NCC Volume Two (Part 1.3)

NCC Volume Three (Part A4)

WHAT IS AN SOU?

A Sole Occupancy Unit (commonly known as an SOU) is

defined in the NCC. It is a part of a building for occupation

by an owner/s, lessee, or tenant, to the exclusion of any other

owner/s, lessee, or tenant. So put simply, it is a space with

an exclusive use in a building.

SOUs can be located in a number of different classifications.

They include:

• A residential apartment or flat

• A self-contained unit

• A suite of rooms in a hotel or motel

• A shop in a shopping centre

CLASS 1 BUILDINGS

DID YOU KNOW?

Class 1 buildings cannot be located above or

below any other dwelling (or any other class of

building) other than a private garage.

Class 1 buildings are houses. Typically they are standalone

single dwellings of a domestic or residential nature. They can

also be horizontally attached to other Class 1 buildings

such as terrace houses, row houses, or townhouses.

In these situations they must be separated by a wall that has

fire‑resisting and sound insulation properties.

The Class 1 classification includes two sub classifications:

Class 1a and Class 1b.

A Class 1a building is a single dwelling being a detached

house; or one of a group of attached dwellings being a town

house, row house or the like.

A Class 1b building is a boarding house, guest house or

hostel that has a floor area less than 300 m2, and ordinarily

has less than 12 people living in it. It can also be four or more

single dwellings located on one allotment which are used for

short-term holiday accommodation.

1 In this document, a building may also refer to a structure such as a swimming pool.

UNDERSTANDING THE NCCGUTTER AND DOWNPIPE PROVISIONS FOR HOUSING

The Performance Requirements of the National Construction Code (NCC) can be met by either using a Performance Solution,1

a Deemed-to-Satisfy Solution (i.e. complying with the DtS Provisions) or a combination of both. The following is a general

representation of the DtS acceptable construction practice provisions in the NCC for the selection and installation of gutters

and downpipes, including overflow measures, for housing. Housing is classified as Class 1 and 10 buildings. It is based on a

national perspective and does not address any State or Territory variations.2 This information is useful for building designers,

hydraulic consultants, plumbers, builders and other on-site trades.The gutter and downpipe provisions for housing are in Volume Two of the NCC.The requirement to install drainage systems from roofs and sub-soil drains should be confirmed with the appropriate authority.

These provisions need only be applied when drainage systems are necessary.

The ABCB has developed a ‘Gutter, Downpipe and Overflow’ (GDO) Calculator which can be found in the

Resource Library of the ABCB website.

EAVE GUTTERSNCC Volume Two (Part 3.5.2)


The ABCB website is www.abcb.gov.au

An eave gutter is a gutter that is fixed to a fascia (or an eave) to catch rainwater running off a roof and is part of a roof drainage system. An eave gutter must be supported by suitably fixed brackets at the stop ends and spaced at not more than 1.2 m centres along the entire length of the gutter. Eave gutters must have a minimum fall of 1:500 (unless fixed to a metal fascia).The minimum size required for an eave gutter is dependent on a number of factors. First, you need to consider the location of the building. Different locations have different rainfall intensities that the roof drainage system must cope with. For selection of eave gutters, a rainfall intensity of 5 minute duration and 20 year average recurrence interval expressed as millimetres per hour (mm/h) is used. Rainfall intensities for different locations are shown in Table 3.5.2.1 of Volume Two.

5 MINUTE DURATION RAINFALL INTENSITY EXAMPLESTable 3.5.2.1 in Volume Two shows that Mackay in QLD has a 5 minute duration rainfall intensity of 250 mm/h for a storm with an average recurrence interval (ARI) of 1 in 20 years. For Albury in NSW, it is 139 mm/h.

The National Construction Code (NCC) is Australia’s performance-based building and

plumbing code. It sets the minimum technical requirements for the construction of new

buildings (and new building work in existing buildings). This document gives an overview

of the Assessment Methods contained within the NCC. Assessment Methods are used

when determining if a Performance Solution or Deemed-to-Satisfy (DtS) Solution complies

with the relevant Performance Requirements. Compliance with the NCC’s mandatory Performance Requirements is achieved by

developing a Performance Solution or a DtS Solution or through a combination of the two.

A Performance Solution uses any method other than the DtS Provisions to comply with the

Performance Requirements. DtS Solutions use the NCC’s DtS Provisions to comply with the

Performance Requirements.

PERFORMANCE SUPPORT MATERIAL

DEVELOPMENT OF

PERFORMANCE SOLUTIONS

The Australian Building Codes Board (ABCB) has produced this document to facilitate the development of performance

solutions. The document is intended for use by all parties with an interest in the formulation of performance solutions that

comply with the Performance Requirements of Volume One, Volume Two and Volume Three of the National Construction

Code (NCC). Compliance with the NCC is only achieved by satisfying the Performance Requirements. This document is

suitable for use in the development of both simple and complex performance solutions. The process requires project

stakeholders to collaborate and develop an agreed pathway for the design process to follow, in order to produce an

acceptable outcome.

A process to assist in the development of a performance solution is outlined below:

WEATHERPROOFINGPBDS 1-001-E

What are the design objectives?

Aside from the client’s objective to utilise an aesthetically pleasing façade

treatment, it has been identified that the cladding must provide a degree of

weatherproofing in order to satisfy the relevant NCC Performance Requirement1.

Who should be consulted?

The client, builder, testing authority, specialist building consultant such as an engineer and regulatory approval authority

are the stakeholder group for this scenario.

What is the basis of the Performance Solution?

As there is no DtS Provisions available, an alternative method is needed to meet the weatherproofing Performance

Requirement, and one way of achieving this is by using the Verification Method FV1 in NCC Volume One.

What evidence is proposed?

• A calculation of the risk score determined in accordance with FV1(a)(i) and Table FV1.1, to demonstrate that the

Verification Method is suitable to use for this scenario.

• Façade drawings demonstrating that the wall cladding type is a direct fixed cladding wall as per the NCC defined

term, because this will dictate the testing specimen characteristics and test procedure required under FV1.

• Testing results of the proposed façade system from an independent testing organisation, to verify FV1 compliance.

Which DtS Provisions are applicable?

There are no DtS Provisions in NCC Volume One for weatherproofing of external façades.

Which Performance Requirement is applicable?

The primary Performance Requirement for the external wall cladding solution in this scenario is FP1.4. However, CP2 is

also an important consideration when developing a Performance Solution for external wall cladding.

FP1.4 Weatherproofing - “A roof and external wall (including openings around windows and doors) must prevent the

penetration of water that could cause—

(a) unhealthy or dangerous conditions, or loss of amenity for occupants; and

(b) undue dampness or deterioration of building elements.”

Note: for brevity, the applicable Performance Requirements have been limited. This solution may also impact other

Performance Requirements and must be considered in accordance with A0.7.

1 It has been assumed that product compliance relating to other sections of NCC Volume One, such as fire resistance, has already been addressed.

The Performance Requirements of the National Construction Code (NCC) can be met

using either a Performance Solution (previously known as an Alternative Solution) or a

Deemed-to-Satisfy (DtS) Solution (complying with the DtS Provisions). The following

demonstrates the performance based design process that may be used with

Verification Method FV1 - Weatherproofing.

Scenario:A property developer has approached a manufacturer of a cladding system and

expressed interest in using the product for an external façade on a proposed low rise

office building. The cladding comprises of a composite board system attached to

masonry using furring channels. The cladding has not been tested in regards to its

weatherproofing properties.

ROOM HEIGHTSPBDS 2-001-D

What are the design objectives?Allow for an unconventional sloped ceiling to suit the fixed furniture placementand aesthetic requirements of the client, being a proportion of the bedroom having a ceiling height of less than 2.4 m. Who should be consulted?The building designer, the client, the builder and the regulatory approval authority are the stakeholder group for this scenario. What is the basis for the Performance Solution?Documented evidence will be used to justify the Performance Solution will demonstrate compliance with the Performance

Requirements. What evidence is proposed?• Written statement relating to the impact of the design on the intended function of the bedroom• Stakeholder peer review and agreement on the solution• A detailed plan showing the area of the room affected by a reduced ceiling height, room layout, including fixed

furniture placement and circulation routes (determined by door and window locations)Which DtS Provision is applicable?Ceiling heights in 3.8.2.2 are required at a height not less than 2.4 m over two-thirds of the floor area of the room.Which Performance Requirement is applicable?Where an alternative ceiling height is proposed as a Performance Solution (Alternative Solution) to that described in Part

3.8.2, that proposal must comply with---(a) Performance Requirement P2.4.2; and (b) the relevant Performance Requirements determined in accordance with 1.0.7.16TP2.4.2 Room heights –16T“A room or space must be of a height that does not unduly interfere with its intended function”Note: for brevity, the applicable Performance Requirements have been limited. This solution may also impact other

Performance Requirements and must be considered in accordance with 1.0.7.

The Performance Requirements of the National Construction Code (NCC) can be met using either a Performance Solution (previously known as an Alternative Solution) or a Deemed-to-Satisfy (DtS) Solution (complying with the DtS Provisions). The following demonstrates a performance based design process and should be used in conjunction with the Development of Performance Solutions Guidance document.Scenario:A homeowner wishes to construct an unconventional sloped ceiling in a bedroom of a Class 1a house. The DtS Provisions require a minimum room height of 2.4 m for at least two-thirds of the floor area of the bedroom. As the proposed design does not meet this DtS Provision, the client intends on having a Performance Solution developed to demonstrate compliance with the relevant NCC Performance Requirement.

or in all jurisdictions. The ABCB takes no responsibility for their unintended use in this context.

HIGH RISE APARTMENT STACKPBDS 3-001-E

What are the design objectives?• Avoid unnecessary build costs, achieve efficiencies through innovative design;

minimise ongoing maintenance.Who should be consulted?• The building owner, the plumbing practitioner, the hydraulic consultant, the

developer, the builder and the regulatory approval authority.What is the basis of the Performance Solution?• Single stack design principles could be extended, based on a reduction in water flows through the use of more water

efficient tapware and fixtures, allowing for fixtures on additional levels to be connected to the stack without increasing

discharge flows. What evidence is proposed?• Comparison with Deemed-to-Satisfy Provisions. Which DtS Provisions are applicable?• B1.2 of Volume Three, which calls up AS/NZS 3500.1• B1.5 of Volume Three, which sets the water efficiency requirements for sanitary fixtures

• B1.6 and B2.6 of Volume Three, which set a maximum flow rate of 9L/minute for shower, basin, kitchen sink and

laundry trough tap outlets• C1.2 of Volume Three, which calls up AS/NZS 3500.2Which Performance Requirements are applicable?• BP1.2 Cold water service installation• CP1.1 Sanitary plumbing systemsNote: for brevity, the applicable Performance Requirements have been limited. This solution may also impact other

Performance Requirements and must be considered in accordance with A0.8.

The Performance Requirements of the National Construction Code (NCC) can be met

using either a Performance Solution (previously known as an ‘Alternative Solution’) or a

Deemed-to-Satisfy (DtS) Solution (complying with the DtS Provisions). The following

demonstrates the performance based design process and should be used in conjunction

with the Development of Performance Solutions Guidance document.Scenario:

A plumber is seeking to design a single stack system for a 12 storey residential

apartment building. However, under the DtS Provisions of NCC Volume Three, the

Plumbing Code of Australia (PCA), a single stack system allows for a 100mm DN stack to

connect fixtures extending a maximum of 10 consecutive storeys only. To overcome this

limitation, a Performance Solution can be considered.

Disclaimer: Please note that this simplified example is only intended for the purpose of learning how to use the NCC. It is not meant to be used as appropriate solutions in all situations

or in all jurisdictions. The ABCB takes no responsibility for their unintended use in this context.

Development of Performance SolutionsThis document outlines a process that can assist you with the development and approval of Performance Solutions. It can be used for simple or complex Performance Solutions.

Performance Solution ScenariosTo assist you develop Performance Solutions, we have a number of scenarios, covering NCC Volumes One, Two and Three. These scenarios cover topics such as room heights, surface water entry, weatherproofing, energy efficiency, macerating toilet systems and press fit jointing methods. Each scenario aligns with the process in the Development of Performance Solutions guidance document shown above.

PERFORMANCE SOLUTION CASE STUDY: FIRE SAFETY

PERFORMANCE SOLUTION CASE STUDY: FIRE SAFETY

HUNTER STREET RENOVATION SITUATION OVERVIEW 39 Hunter Street was constructed in Sydney in 1917 and is now

a heritage listed office building. Jackson Teece architecture,

building services and fire engineering designers from Arup,

and Hyder structural engineers, along with building certifier

Hendry Group, were engaged to design and deliver an open

atrium through the office building to enhance the building’s

environmental performance. The design team determined that a Deemed-to-Satisfy (DtS)

Solution would not enable the sensitive reuse of the partially

open heritage fire stair as it would have required it to be fully

enclosed in fire rated construction, all the way to an external

discharge point. The team also identified a DtS Solution would

not achieve the client’s desire for the floors to be “open” to

the atrium.

and how they could be combined to improve the heating

and cooling load performance, as opposed to just minimum

compliance or a star rating. • The clients were able to optimise the thermal performance

of the proposed addition without the need to assess parts

of the existing house that would remain unchanged.

• The analysis software used provided highly visual feedback

on factors such as incident solar radiation, shading and

internal heat gains. • The Performance Solution helped to determine the most

cost-effectiveandpragmaticapproachtoachievethe

requiredenergyefficientperformance.

PERFORMANCE SOLUTION CASE STUDY: DISABILITY ACCESS

RILEY STREET APARTMENTS SITUATION OVERVIEW Independent architect, Steven Bishop of SJ Bishop Architect,

was asked to deliver a five storey mixed-use building containing

sole occupancy residential apartments, retail/commercial

tenancy, basement storage and plant, and rear access split

level, car stacker parking. The requirements for the residential units included wheelchair

access, which was difficult due to the narrowness of the site

(8.5m wide x 24m long) and the need to also accommodate

retail/commercial access and carpark access. In conjunction

with the Access Consultant and client, Steven identified a

Performance Solution for a wheelchair compliant lift size

which maximised “livable” space in the residential apartments. PROJECT HIGHLIGHTS Name:

Riley Street Apartments

Location: Woolloomooloo, NSW

Project Type: New construction

Building Type: Mixed use building

Performance Solution: Disability access Architect:

SJ Bishop Architect Access Consultant: Accessibility Solutions

www.abcb.gov.au

PERFORMANCE SOLUTION • The site geometry was the prime determinant for using

a Performance Solution given the lift shaft size for an

access compliant lift would have taken up a large

proportion of site width, resulting in narrow access

or uncomfortably small rooms in adjacent areas.

• SJ Bishop used three assessment methods to achieve

compliance with the Performance Requirements, including

Evidence of Suitability, Comparison with the Deemed-to-

Satisfy Provisions and Expert Judgement. • An Access Consultant was engaged to undertake

the review of the Performance Solution. The consultant

determined that although a compliant accessible lift

requires enough width for a wheelchair user to “turn

around” inside the lift (i.e. to get in and out without

having to reverse), SJ Bishop’s performance solution

delivered a “through lift” which enabled the clear width

provisions to be reduced. The Access Consultant

prepared a report to demonstrate compliance with

the Performance Requirements. • The final design specifications which were deemed

acceptable was a Schindler 5500 series lift (1200 wide internally). • Benefits:• maximises the building’s nett lettable floor area

• enables entry and exit of service vehicles in a

forward direction • minimal impact on the building design due to

optimum space efficiency• performance enabled the use of an existing lift

product, but expanded the scope of its uses to

allow for flexibility in functional design

PRODUCT CERTIFICATION SCHEMES

WaterMarkWaterMark is a mandatory certification scheme for plumbing and drainage products to ensure they are fit for purpose and appropriately authorised for use in plumbing and drainage installations.

The ABCB manages and administers WaterMark as a national scheme. Volume Three, the PCA, requires certain plumbing and drainage products to be certified and authorised for use in a plumbing or drainage installation. These materials and products are certified and authorised for use through WaterMark.

Products complying with these requirements may be certified and authorised for use upon the granting of a WaterMark licence. Licensed materials and products are to be listed on the WaterMark Product Database identified by the WaterMark trade mark, which must be displayed on the material or product.

To support the operation and management of WaterMark ABCB provides a variety of resources, including The Manual for the WaterMark Certification Scheme, WaterMark Technical Specifications, videos and general Scheme information.

Manual for the WaterMarkCertification SchemeWaterMark Certification Scheme2016

WaterMark Certification Scheme

There is a requirement in the National Construction Code Volume Three – Plumbing Code

of Australia for certain plumbing and drainage products to be certified and authorised for

use in a plumbing or drainage installation. These products are certified and authorised

through the application of the WaterMark Certification Scheme.

Certified products are listed on the WaterMark Product Database and are identified by

the WaterMark certification trademark, which must be marked on the product upon

the granting of a WaterMark Licence. To search the Database, go to www.abcb.gov.au.

The Australian Building Codes Board (ABCB) manages and administers the WaterMark

Certification Scheme for plumbing and drainage products. The Joint Accreditation System

of Australia and New Zealand (JAS-ANZ) accredits WaterMark Conformity Assessment

Bodies (WMCABs), who in turn evaluate and certify plumbing and drainage products.

The Scheme is governed by the Rules for the WaterMark Certification Scheme, including

the Approved Certifier and Approved User Agreements, and the Manual for the WaterMark

Certification Scheme. The Manual details the operating structure of the Scheme, and

the process and procedural requirements for the certification of plumbing and drainage

products, risk assessment and drafting product specifications.

The Rules and the Manual are available from www.abcb.gov.au

PRODUCT CERTIFICATION SCHEMES

CodeMark AustraliaCodeMark Australia is a voluntary third-party building product certification scheme that authorises the use of new and innovative products in specified circumstances in order to facilitate compliance with Volumes One and Two of the NCC.

The CodeMark Australia Scheme provides confidence and certainty to regulatory authorities and the building industry through the issue of Certificates of Conformity, which is one of several options available for meeting the ‘evidence of suitability’ requirements of the BCA.

State and Territory legislation requires building approval authorities to accept CodeMark Australia Certificates of Conformity as evidence of compliance with the BCA, providing the product is used as specified on the certificate.

To support the management of CodeMark Australia, available from the ABCB website are the CodeMark Australia Scheme rules, Certification framework and general Scheme information.

What is the CodeMark Australia

Certification Scheme?

CodeMark Australia is a voluntary third‑party building product certification scheme

owned by the Commonwealth of Australia acting on behalf of the Commonwealth

and all States and Territories. It supports the use of new or innovative building

products in specified circumstances in Australia by providing a nationally accepted

process for demonstrating compliance with the requirements of Volumes One

and Two of the National Construction Code, also known as the Building Code of

Australia or BCA.

Certificates of Conformity issued under the CodeMark Australia scheme are one

of several options available for meeting the ‘evidence of suitability’ requirements of

the BCA.

State and Territory building control legislation requires building control authorities

to accept CodeMark Australia Certificates of Conformity as evidence of compliance

with the BCA, as long as the product is used as specified on the certificate.
