Slide 1

Understanding the NCC accessibility provisions.

Before we go on with the rest of the presentation, let’s take a moment to understand what accessibility means, both generally and in the context of the NCC.

The accessibility provisions in NCC Volume One are designed to ensure buildings are designed and constructed in a way to ensure that  most people can access them. This includes access for people with a disability such as a:

  • vision or visual impairment
  • hearing impairment
  • physical or mobility-related disability
  • brain injury
  • cognitive or intellectual disability; and
  • mental health conditions.

However, it's not just people with disability who experience barriers to accessing and using buildings. Potential barriers to access may affect anyone – both people with and without disability. Good access has benefits for all people. For example, families with small children, people with temporary injuries and anyone delivering or picking up goods.

Let’s consider three examples of how a person’s needs can affect building design:

    • The absence of contrast on stair nosings makes stairs more hazardous for all users but especially for people with a visual impairment.
    • A stepped entrance creates a barrier for people who use wheelchairs and other people with impaired mobility such as sore knees and hips.
    • A place with amplified sound, such as a theatre or conference venue, can challenge peoples’ ability to hear clearly.


In Australia, anti-discrimination laws exist to protect people with a disability from discrimination. The definition of disability shown here in this excerpt from the Commonwealth Disability Discrimination Act 1992,or DDA,is very broad and covers about 20% of Australians.

Accessibility provisions have existed in the Code since 1990. The chief focus of the NCC’s accessibility provisions is on commercial and public buildings, i.e. Class 3 and Class 5 to 9 buildings. There are some requirements for certain Class 1b and Class 10 buildings and structures, and parts of Class 2 buildings.

The terms ‘accessible’ and ‘accessway’ are both defined terms in the NCC and these definitions are found in Schedule 3 of all NCC Volumes. 

Although the Code has had accessibility requirements since 1990 there were inconsistencies between the Code requirements and the DDA. This led to uncertainty for the building industry including developers, designers, builders and certifiers. As a consequence, there were a number successful DDA complaints about Code compliant buildings.

To address the inconsistencies between building law and the DDA, the Commonwealth Government resolved to develop a Disability Standard covering buildings, which would be reflected in the Code when completed. The Code was updated in 2011 as a result.

The NCC accessibility provisions reflect the requirements of the Disability (Access to Premises – Buildings) Standards 2010, known as the Premises Standards. The Premises Standards were developed to provide certainty in relation to the levels of access to public buildings would satisfy the general non-discrimination requirements of the DDA.  They provide a uniform set of requirements that apply both in relation to non-discriminatory access under the DDA and in relation to the requirements for access that must be complied with in order to obtain building approval under building law.


Slide 2

What are the NCC accessibility provisions?

The NCC sets out the minimum Performance Requirements for the provision of safe, equitable and dignified access to buildings. The overall access objectives are to ensure:

  • As much as possible, that people can access and use buildings safely, equitably and with dignity. This includes access to services and facilities within a building.
  • It also includes that buildings provide a ‘continuous accessible path of travel’ i.e. one that does not include features that might impede safe, equitable and dignified movement and access to facilities. This includes travel to a building, within a building and leaving a building.

Examples of adhering to the access principles include:

  • Accessible entry to a new building must be the principal pedestrian entrance and not one around the back of the building.
  • It also includes gaining access to a swimming pool should not rely on someone having to be carried into it.

While there are some exceptions and exemptions within the NCC, access is required to most spaces and facilities within a building used by the occupants - who may be customers, visitors or staff.

The NCC is mainly concerned with the physical construction of the building. Generally speaking, what happens after construction in terms of fit out and ongoing use and management are not covered by the NCC, but continue to be covered by discrimination law.

The NCC does not address these three areas:

  • Fixtures and fittings used in a building, such as furniture or reception desks.
  • It doesn’t include way finding information, such as room numbers or general information signs, and
  • It also doesn’t address, management policies or staff behaviour – for example, if the staff at a nightclub refuse to allow a blind person entry.

So, it is important to comply with the accessibility provisions in the NCC, so that a building is built in such a way as to be as accessible to as many people as possible.


Slide 3

Let’s look at some practical examples of how Accessibility applies.

  1. To a building from the allotment boundary.
  2. Between associated buildings that are required to be accessible.
  3. The next is, between levels (via lifts, ramps and stairs).
  4. In most buildings, to all areas normally used by the users.
  5. To signage including braille and tactile.
  6. To hearing augmentation services.
  7. And finally, to suitable sanitary facilities.


Slide 4

NCC Volume One contains a number of sections with requirements relevant to accessibility. It is easier to look at the Table of Contents and see that Section D is relevant, but you need to look beyond this to identify the other provisions in other Sections.

For accessibility, there are a total of:

  • Nine Performance Requirements across three Sections of NCC Volume One, which are Sections D, E and F.
  • Four Verification Methods across Sections D, E and F.
  • Thirty-five DTS Provisions across four Sections, which are Sections D, E, F and H, and
  • Four Specifications across Sections D, E and F.

Performance Requirements represent minimum requirements. Building owners, designers and builders can choose to introduce additional or alternative measures to provide greater accessibility within a building and to its occupants. For example, a care home or day centre for people with disability.

Section A Governing Requirements is common across the NCC and covers how to use and apply the NCC itself. The various Parts of Section A can apply to accessibility, for example:

  • Part A1 Interpreting the NCC - describes how to interpret provisions within the NCC, including things like Application statements, Limitation statements and Exceptions statements. 
  • Part A5 Documentation of design and construction - describes the requirements for evidence and documentation to prove compliance with relevant access Performance Requirements.
  • Part A6 Building classifications - describes the building classes, which in part determine which accessibility provisions apply to a building or part of a building.
  • Part A7 - describes the treatment of united buildings, which can have implications for accessibility requirements.

The three main sections of NCC Volume One containing Performance Requirements related to accessibility are:

  • Section D Access and egress, which:
    • Focuses on how people enter, leave and move around a building. This obviously has implications for the ease with which people with disabilities can access and move around the building, and how they can evacuate from the building in an emergencies.
    • Has seven Performance Requirements relevant to access for people with disability, as well as two relevant Verification Methods, plus twelve Parts containing DTS Provisions, and two relevant Specifications.
  • Section E Services and equipment, which:
    • Contains provisions related to the use of lifts for evacuation of people with disability.
    • It has one relevant Performance Requirement, one Verification Method, three DTS Provisions and one relevant Specification.
  • Section F Health and amenity, which:
    • Contains provisions related to the provision of sanitary facilities that are accessible.
    • It has one relevant Performance Requirement, one Verification Method, five DTS Provisions and one relevant Specification.

Section G contains Ancillary provisions.

These are specific provisions that can impact on access that apply in limited circumstances.

  • Part G3 applies to atrium construction and includes additional DTS Provisions to ensure safe access and egress.
  • Part G4 relates to construction in alpine areas and contains additional Performance Requirements and DTS provisions that impact on access and egress.
  • And Part G6: Occupiable outdoor areas, includes an inclusion of an occupiable outdoor area in the definition of a story potentially impacting on passenger lists and access paths.

Additional requirements for specific applications and building uses are also contained in Section H Special use buildings. This contains fifteen additional DTS Provisions that apply only to Class 9b or Class 10 public transport buildings, as listed on the slide.

Section H does not contain any Performance Requirements, only DTS Provisions.

The provisions within Part H2 Public transport buildings derive from the Disability Standards for Accessible Public Transport 2002. This is a national disability standard, agreed to by Australian governments. The design specifications in the Disability Standards for Accessible Public Transport 2002 are sometimes different to those that generally apply within the NCC. As a result, Part H2 sometimes refers to different editions of Australian Standards for things like accessways, ramps, stairways, signage, lifts and doorways. 

If there is a different between some aspect of a DTS Provision in Part H2 and some aspect of a related provision in another Section of the NCC, then the provision within Part H2 takes precedence.


Slide 4

In broad terms, Section D requires buildings to allow for safe movement into, out of and within a building.

It primarily addresses:

  • Access and carparking.
  • Movement to and within a building, and
  • Safe evacuation during an emergency.

Performance Requirements

All the Performance Requirements for Section D are at the front of the Section.

There are nine in total. Their names pretty well define what they are about.

Seven of these are relevant to access for people with disabilities.

Verification Methods

Section D also describes four Verification Methods, which may be used as Performance Solutions to assess compliance with part or all of the Performance Requirements of Section D.

Two of these Verification Methods are relevant to access for people with disability.

  • Verification Method DV2 provides a way to verify that a building provides safe and equitable access to and within a building. It verifies compliance with DP1, DP2, and DP6.  (As well as EP3.4 and/or FP2.1)
  • The next is, Verification Method DV3 and it provides a way to verify compliance with DP2 to provide safe movement to and within a building via ramps used by wheelchairs.

Remember, a Verification Method is just one way to verify compliance via a Performance Solution.

DTS Provisions

The relevant Deemed-to-Satisfy Provisions in Section D are contained in Part D3 Access for people with a disability.

A number of these provisions apply differently in different building classifications.

Some points that you need to consider include:

  • D3.1 contains general building access requirements while D3.2 specifies the extent of access that must be provided to buildings. Different classes of buildings may have different access requirements. For example, an office building (Class 5) would generally require access to all areas normally used by the occupants, whereas hotels (Class 3) would only require access to common areas of the building and some of the hotel rooms or units, but not all.
  • D3.3 specifies accessways within buildings.
  • D3.4 contains a number of exemptions for providing access.
  • D3.6 covers access signage while D3.7 specifies requirements for systems to assist those with hearing impairments.
  • D3.8 specifies requirements for tactile indicators to assist people with visual or vision impairment to avoid hazardous situations.
  • D3.9 specifies requirements for wheelchair seating spaces within Class 9b assembly buildings – for example a sporting stadium.
  • D3.11 specifies requirements for ramps that are part of a designated accessway, and
  • D2.12 contains specified requirements for glazing within an accessway.



There are also two specifications supporting the accessibility provisions in Section D, which are Specification D3.6 Braille and tactile signs, and D3.10 Accessible water entry/exit for swimming pools.

Specifications contain detailed information to apply the relevant DTS Provisions. Tactile means relating to our sense of touch.

A tactile sign is one that you can touch in order to gain information from it.”


Slide 5

Let’s look at the Performance Requirements for accessibility in Section D. As you can see here, there are four Performance Requirements – DP1, DP6, DP7 and DP9. One thing to remember about Performance Requirements is that they will be either qualitative or quantitative. A qualitative Performance Requirement specifies an attribute that must be achieved, whereas a quantitative Performance Requirement will specify a value that provides an absolute measure of performance.

Let’s look at DP1 Access for people with a disability.

DP1 essentially specifies that people with a disability must be able to access a building and be able to access work and public spaces and sanitary facilities within the building.

The term, “…to the degree necessary…” shows that this Performance Requirement is qualitative in nature. It gives you flexibility in implementation and recognises that different degrees of access may be required for different buildings. Section A Governing Requirements provides further details of what this  means in respect to meeting a Performance Requirement.

The terms “accessible” and “accessways”, shown here in blue italics, are defined terms in the NCC. Accessible means having features to enable use by people with a disability.

Examples include absence of steps and other level changes, use of ramps, automatic doors, wider doorways and access ways, tactile signage lift buttons and maps, and hearing lips.

Accessway means a continuous accessible path of travel as defined in AS 1428.1 to, into or within a building.

AS 1428.1 Design for Access and Mobility- General Requirements for Access-New Building Work, incorporating Amendments 1 & 2.

Note the limitation for DP1, it does not apply to a Class 4 part of a building.

There's also an ACT Appendix. This appendix contains variations and additions to the NCC that apply to building work undertaken in the ACT and information about the application of the NCC in the ACT.

DP6 Paths of travel to exits - This is about ensuring that all occupants can safely exit a building.

This is a qualitative Performance Requirement – note the words ‘appropriate to’.

The critical factors that are highlighted here are important. We need to ensure that we make exit pathways wide enough for the likely number and capacity of users, including people with a disability and the speed with which users must evacuate given the likely fire load of the building.

There's also a limitation for this Performance Requirement. It does not apply to single occupancy units in Class 2 or 3 buildings or Class 4 parts of a building because occupants are likely to be familiar with the layout of the building and will know where and how to quickly reach the exits.

DP7 Evacuation lifts - is also a qualitative Performance Requirement – note the words, “appropriate to”. There is a range of critical factors applying to this Performance Requirement as highlighted here.

We need to consider each critical factor, for example how far occupants have to go to reach the lift, how many people are likely to need the lift, other fire safety systems in the building, how long it will take to evacuate occupants using the lift, and how reliable the lift is likely to be.

DP9 requires that a building has an inbuilt communication system for entry, information entertainment or for the provision of a service, that must be suitable for occupants who are deaf or hearing impaired. This is a qualitative requirement – note the words, be suitable.

A limitation also applies to this Performance Requirement. It does not apply to a Class 4 part of a building. It also does not apply when an in-built communication system is only used to broadcast emergency warnings.


Slide 6


DTS Provisions: D3 Access for people with a disability.

Let’s have look at the sub-Part D3.0 Deemed-to-Satisfy Provisions – this is like an overview on applying Part D3.

D3.0 is basically outlining how a DTS Solution under this Part, can meet a number of Performance Requirements. It also covers the use of Performance Solutions. Let’s look at the three clauses here.

Clause (a). This is a general statement of what is required for a compliant DTS Solution, and outlines what Performance Requirements can be met by complying with specific DTS Provisions as per (a)(i).

If a DTS Solution meets all of the DTS provisions in D1, D2 and D3 as appropriate, then it is deemed compliant with eight of the nine Performance Requirements in Section D, i.e., DP1 to DP6 and DP8 and DP9.

Note in sub-clauses (ii) to (v) that there are additional provisions that may apply for certain buildings. These provisions include Section G Ancillary Provisions, and Section H Special use buildings. All other provisions in D3 must be complied with.

Clause (b). You can use a Performance Solution to meet one or more of the Performance Requirements.

Remember that the NCC Provisions must be applied holistically, so implementing a Performance Solution to meet one requirement may impact on other Performance Requirements, DTS Solutions or Performance Solutions.

Clause (c), there’s no need to develop a DTS Solution or a Performance Solution for DP7 unless lifts will be used to evacuate occupants from a building.


Slide 7

Now, let’s practice locating and interpreting information about the DTS Provisions in Part D3.

Let’s now look at some questions to test your knowledge.

Question 1:According to Part D3.1, what parts of a Class 2 building must be accessible, as defined by the NCC?

Answer 1:

  • Table D3.1 Requirements for access for people with a disability.
  • Access is required to common areas within the building.
  • From a pedestrian entrance that must be accessible to at least one floor containing Single Occupancy Units and to the entrance doorway of each SOU on that level.
  • To and within not less than one of each type of room or space for use in common by the residents, including a cooking facility, sauna, gymnasium, swimming pool, common laundry, games room, individual shop, eating area, or the like.
  • Where a ramp complying with AS 1428.1 or a passenger lift is installed:
    • (a) to the entrance doorway of each SOU, and
    • (b) to and within rooms or spaces for use in common by the residents that are located on the levels served by the lift or ramp.


Question 2: According to Part D3, what areas are not required to be accessible in a Class 2 to 9 building?

Answer 2:

  • Part D3.4 Exemptions.
  • The following areas are not required to be accessible:
    1. An area where access would be inappropriate because of the particular purpose for which the area is used
    2. An area that would pose a health or safety risk for people with a disability
    3. Any path of travel providing access only to an area exempted by (a) or (b)
  • For example, you would be unlikely to need to provide wheelchair access to a diving platform at a swimming pool because it would be dangerous to use a wheelchair on such a ramp.

Question 3: According to Part D3, how many parking spaces would need to be reserved for people with disability in a shopping centre with parking for a total of 1200 cars?

Answer 3:

  • Part D3.5 Accessible car parking.
  • Table D3.5 Car parking spaces for people with a disability.
  • 22 car parking spaces for people with a disability are required.
  • So we divide 1000 by50 which gives us 20 spaces and  200 divided by 100 gives us 2 spaces for a total of 22 spaces.

Question 4: According to Part D3, what Australian Standard must signage in an accessible building comply with?

Answer 4:

  • Part D3.6 Signage, various clauses.
  • AS 1428.1 Design for access and mobility – General requirements for access – New building work.


Question 5: According to Part D3, when are tactile ground surface indicators required in a Class 2-9 building?

Answer 5:

  • Part D3.8 Tactile indicators, Clause (a).
  • Must be provided to warn people who are blind or have a vision impairment that they are approaching:
    • Any stairway that is not a fire-isolated stairway, and any ramp that is not a fire-isolated ramp, step ramp, kerb ramp or swimming pool ramp
    • An escalator or a passenger conveyor or moving walkway
    • If there are no suitable barriers:
      • An overhead obstruction less than 2 m above floor level, other than a doorway, and
      • An accessway that meets a roadway next to a pedestrian entrance to a building, if there is no kerb or kerb ramp at that point, excluding a pedestrian entrance serving an area covered by exemptions in D3.4, and areas exempted by D3.4.


Question 6: An auditorium, that can accommodate up to 650 people, has a hearing augmentation system that uses receivers. What percentage of the floor area must be covered by the hearing augmentation system? How many receivers are required in the auditorium?

Answer 6:

  • Part D3.7 Hearing augmentation, Clause (b).
  • The hearing augmentation system must cover at least 95% of the floor area served by the auditorium’s inbuilt amplification system.
  • This equates to 25 receivers being required (in other words 20 plus 5).


Slide 8

Let’s look at some key accessibility requirements in Section E services and equipment.

EP3.4 Lift access for people with a disability

  • If a building is required to be accessible, then any lifts provided in that building must be accessible lifts.

E3.5 Landings

  • If a building that is required to be accessible has a passenger lift, then the landings for the liftwell have to comply with the accessibility requirements of Section D, Part D3.
  • This will potentially affect things like the dimensions of the landing areas and the width of the corridors leading to the landing.

E3.6 Passenger lifts

  • Part E3.6 identifies the range of lifts that can be used in buildings.
  • While the range is broad and allows for more cost effective approaches, especially for small buildings, there are some limits on each type of lift can be used. Some types of lifts include:
    • An electric passenger lift.
    • A stairway platform lift which follows the flight of stairs on rails fixed at one side.
    • A low-rise platform lift.
    • An inclined lift.
    • Table E3.6b provides general requirements for the main features of different lift types which include requirements for all lifts:
    • They must have a handrail, apart from stairway platform lift and low-rise lift.
    • They must have a minimum lift floor dimension of 1400 mm by 1600 mm, if they travel more than 12 m and 1100 mm x 1400 mm if less than 12 m.
    • They must have lift landing doors at the upper landing, apart from stairway platform lifts, and
    • They must also have automatic audible information within the lift car to identify the level each time the car stops, if they are to serve more than 2 levels.

E3.8 Residential care buildings

  • This only applies to a Class 9c residential care building.
  • In these buildings, there is a high likelihood that some of the occupants will not be able to evacuate on their own. Therefore, the building’s design and construction needs to take this into account.

If any occupants might need to evacuate from a level that doesn’t go directly out on the street or some form of open space, then the provisions shown must be met.


Slide 9

Let’s look at some key accessibility requirements in Section F - Health and amenity.

In FP2.1 Personal hygiene facilities, we can see here that suitable sanitary facilities for personal hygiene must be provided in a convenient location within or associated with the building to the degree necessary appropriate to the function or use of the building, the number and gender of the occupants, and the disability or other particular needs of the occupants.

A convenient location means the occupants must be able to reach them easily.

Within or associated with the building means not necessarily in the building as long as they can be easily reached from the building itself.

In F2.2: Calculations of the number of occupants and facilities, the number of sanitary facilities required in the building is based on the maximum number of persons who will use the building.

It is calculated by floor space using Table D1.13, unless there is a better way to do it. Unisex facilities for use by people with a disability can be counted as one facility for each sex, e.g., if a building needs five closet pans per gender and it has one unisex facility, then it needs four other closet pans per gender.

In F2.4 Accessible sanitary facilities, the general term ‘accessible sanitary facilities’ refers to:

  • Accessible unisex sanitary compartments ( generally referred to as ‘accessible unisex toilets’, not ‘disabled toilets’).
  • Or accessible unisex showers.
  • Or toilets suitable for people with ambulant disabilities.

Part F2.4 sets out:

  • Where accessible unisex sanitary compartments and unisex showers are required to be provided.
  • As well as the requirements for ambulant accessible toilet cubicles.

Generally, accessible unisex sanitary compartments must be provided:

  • In buildings required to be accessible and containing toilets, and
  • On every accessible storey where there are toilets.

Some individuals may require assistance using a toilet. Accessible toilets are therefore required to be unisex to allow for assistance by someone of any gender without entering an area reserved for a specific gender.

Circulation spaces and features of an accessible unisex toilet must comply with AS 1428.1: Design for access and mobility – General requirements for access – New building work.

While the NCC only requires a closet pan, washbasin, shelf or bench top and a sanitary towel disposal bin within a toilet, if other fixtures and fittings are included, such as a soap dispenser or mirror, they must also comply with the requirements of AS 1428.1.

We also need to consider ‘ambulant accessible toilets’.

A person with an ambulant disability is someone who is able to move about without the need for a wheeled mobility device, but would benefit from a raised pan and handrails to assist in raising and lowering.

F2.9 Accessible Adult change facilities.

The NCC requires accessible adult change facilities to be provided in some Class 6 shopping centres and some Class 9b buildings, depending on their purpose, floor space area and design occupancy levels.

This requirement is primarily targeted at large public buildings including shopping centers, sports stadiums, aquatic centers, museums, art galleries and airports.

Part F2.9 in conjunction with Specification F2.9, sets out the particular requirements and specifications for accessible adult change facilities.


Slide 10

Let’s now look at some questions so we better understand how to interpret the DTS provisions in Part F2.

Question 1:According to Part F2, what facilities/elements must an accessible unisex sanitary compartment contain?

Answer 1:

  • F2.4 Accessible sanitary facilities.
  • An accessible unisex sanitary compartment must contain a:
    • closet pan
    • washbasin
    • shelf or benchtop, and
    • means for disposing of sanitary products.

Question 2: According to Part F2, where and how many accessible unisex sanitary compartments must be located in a Class 5, Class 6, or Class 7 building?

Answer 2:

  • Part F2.4 Accessible sanitary facilities.
  • Table F2.4(a) Accessible unisex sanitary compartments.
  • If closet pans are required according to F2.3, then:
    • One unisex sanitary compartment must be located on every storey that contains sanitary compartments.
    • If there is more than one bank of male and female sanitary compartments on any storey, then one unisex sanitary compartment must be located at not less than 50% of those banks.

For example, if there are four sets of sanitary compartments on a floor, then at least two of those sets must have an accessible unisex sanitary compartment.

Question 3: According to Part F2, where and how many accessible unisex showers must be located in a Class 5, Class 6, or Class 7 building?

Answer 3:

  • Part F2.4 Accessible sanitary facilities.
  • Table F2.4(b) Accessible unisex showers.
  • If one or more showers are required according to F2.3, then there must be at least one accessible shower for every ten showers, or part thereof.

So, for example, if there:

  • Is one shower required, then it must be an accessible shower, or there must be an additional accessible shower.
  • If two showers are required, then one must be an accessible shower.
  • If 10 showers are required, then one must be an accessible shower.
  • If 11-20 showers are required, then two must be accessible showers.
  • If 21-30 showers are required, then three must be accessible showers.


Question 4: Where in Part F2 will you find requirements for hoists, change tables, changing rails and signage in an accessible adult change facility?

Answer 4:

  • Specification F2.9 Accessible adult change facilities.
  • Clause 3 is Hoist.
  • Clause 7 deals with Change tables.
  • Clause 8 is Changing rails, and
  • Clause 10 is Signage.


Slide 11

In which Section and Part will you find the DTS Provisions related to…

  • Accessible passenger lifts?
  • Sanitary facilities for people with disability?
  • Car parking for people with a disability?
  • General access requirements for people with a disability?
  • Hearing augmentation systems?
  • And access in public transport buildings?

Pause this video and look up the relevant section and parts before continuing to see the answers.


  • Accessible passenger lifts? Section E, E3.6 Passenger Lift
  • Sanitary facilities for people with disability? Section F, Part F2.4 Accessible sanitary facilities
  • Car parking for people with a disability? Section D, Part D3.5 Accessible car parking
  • General access requirements for people with a disability? Section D, Part D3.1 General building access requirements
  • Hearing augmentation systems? Section D, Part D3.7 Hearing augmentation
  • And access in public transport buildings? Section H, Part H2 Public transport buildings

Slide 12

Assessment methods for accessibility.

Whether you choose to use a DTS Solution or a Performance Solution or a combination of the two, you may need to provide some evidence that the proposed solution complies with the Performance Requirements.

The NCC recognises four valid ways of assessing possible compliance solutions, which are shown here.

All four methods can be used to demonstrate compliance with all or part of the Performance Requirements when you are using a Performance Solution. 

Evidence of suitability and Expert Judgement can be used when you are using a DTS Solution.

The various accessibility related Sections and Parts of NCC Volume One include a number of relevant Verification Methods, each of which can be used in certain circumstances.


Slide 13

Let’s look at some questions to confirm your understanding of Verification Methods for accessibility.

Which of the access related Vertification Methods in Volume One could you use in each of the following circumstances?

Question 1: To verify that the proposed number of sanitary facilities in a building complies with FP2.1?

Answer 1: FV2.1 Sanitary facilities.

Question 2: To verify compliance with access requirements to and within a building, using a reference building?

Answer 2: DV2 Access to and within a building.

Question 3: To verify compliance with requirements for the slip resistance of a wheel-chair ramp?

Answer 3: DV3 Ramp gradient, crossfall, surface profile and slip resistance for ramps used by wheelchairs.


Slide 14

Let’s have a go at applying the accessibility provisions by looking at a typical building covered by Volume One.

This is a …

  • Multi-storey office building
  • With 2300 m2 floor area
  • It has kitchen and shower facilities on each floor, and
  • Entry from street level with underground parking.

So let’s ask ourselves the key questions pertaining to the accessibility requirements for this building. We need to consider;

  • What classification is the building?
  • Are there common areas within the building?
  • What are the principal paths of travel within the building?
  • Which accessibility related Performance Requirements would apply?
  • What DTS provisions would apply, for example: how would you calculate the number of accessible sanitary compartments required in the building?
  • And also, what requirements could apply to:
    • Passenger lifts?
    • Evacuation lifts?
    • Signage and hearing augmentation?
    • And sanitary facilities?

Which aspects of the building do you think require the greatest consideration?

How can the requirements be met so that building occupants and visitors are provided with safe, equitable and dignified access to and within the building?

Take a moment to consider these questions.


Slide 14

There are some other useful resources that can be accessed.

Compliance with AS 1428.1 Design for access and mobility – General requirements for access – New building work is mandatory if you have chosen to use a DTS Solution and this standard is referenced in an applicable provision.

Use of the Guide to NCC Volume One and the handbook is not mandatory. They provide guidance and help, but nothing in them needs to be complied with in order to comply with the NCC.


Slide 15

So, in summary, Section D: Access and egress, contains the main provisions relating to accessibility in Volume One in Part D3.

It contains how people enter and move around the building, accessible car parking, and also covers safe evacuation during an emergency.

Section E: Services and equipment contains accessibility of passenger lifts and lifts used for evacuation.

Section F: Health and amenity contains accessible sanitary facilities and accessible adult change facilities.

Section G: Ancillary provisions contains additional DTS provisions for buildings in alpine areas, buildings with atriums and occupiable outdoor areas.

And finally, Section H: Special use buildings. This contains DTS provisions for accessibility in passenger use areas of public transport buildings.


Slide 16

There are a number of key points from this presentation:

The overall aim of accessibility provisions is to provide safe, equitable and dignified access to:

  • A building, and
  • Its services and facilities

This is more than just ramps and wheelchair access.

Should consider how building is likely to be used and by whom.

Accessibility provisions apply to new buildings and upgrades to existing buildings, with some concessions under the Premises Standards.
