Part I2 Public transport buildings

Part I2 Public transport buildings

Introduction to this Part

This Part provides additional Deemed-to-Satisfy Provisions for Class 9b and Class 10 buildings that are used as public transport buildings. The provisions of this Part are based on the Disability Standards for Accessible Public Transport 2002 (Transport Standards).

Performance Requirements

The Objectives and Functional Statements for Part I2 are contained in Sections D, E and F of this Guide. The Performance Requirements for Part I2 are contained in Sections D, E and F. Part I2 contains Deemed-to-Satisfy Provisions for Class 9b and Class 10 public transport buildings additional to those contained in Parts D4, E3 and F4 that apply to public transport buildings.

Deemed-to-Satisfy Provisions

(1) The Deemed-to-Satisfy Provisions of this Part apply to the passenger use areas of a Class 9b or Class 10 building used for public transport.

(2) The Deemed-to-Satisfy Provisions of this Part take precedence where there is a difference to the Deemed-to-Satisfy Provisions of Parts D4, E3 and F4.

(3) For an airport that does not accept regular public transport services, as defined in the Disability Standards for Accessible Public Transport 2002, only I2D8, I2D9, I2D10, I2D11, I2D12 and I2D13 of this Part apply.

(4) Exemption (1) to A6G1(1) does not apply to this Part.

Explanatory information

Part I2 contains Deemed-to-Satisfy Provisions for Class 9b and Class 10 public transport buildings additional to those contained in Parts D4, E3 and F4 that apply to public transport buildings.

To clarify which public transport buildings are subject to Part I2 and to what extent they are subject.

Part I2 specifically relates to buildings associated with public transport services, such as railway stations, bus interchanges, airports and ferry terminals. These requirements were previously located in the Disability Standards for Accessible Public Transport 2002 (Transport Standards). Some versions of Australian Standards referred to in Part I2 may be different to those referred to in the remainder of the BCA. The correct version of the Australian Standard to be used can be determined by reference to Schedule 2.

I2D1(1) provides that the Deemed-to-Satisfy Provisions of Part I2 apply to the passenger use areas of Class 9b or Class 10 buildings used for public transport. Class 9b and Class 10 public transport buildings must also satisfy the Deemed-to- Satisfy Provisions of Parts D4, E3 and F4.

I2D1(2) provides a rule for resolving inconsistencies between these requirements imposed on public transport buildings by providing that the Deemed-to-Satisfy Provisions of Part I2 take precedence where there is a difference.

I2D1(3) provides that, as under the Transport Standards, certain requirements in Part I2 do not apply to ‘airports that do not accept regular public transport services’ as defined in the Transport Standards.

I2D1(4) provides that the exemption to A6G1(1) does not apply to Part I2 because the application of this provision to Part I2 could result in a different outcome to what would have been achieved under similar provisions that existed in the Transport Standards. Under the exemption to A6G1(1), if 10% or less of the floor area of a storey is used for a purpose which could be classified differently to the remainder of that storey, that part may be classified as being the same as the remainder.

(1) An accessway must comply with AS 1428.2.

(2) If an accessway branches into 2 or more parallel tracks—

  1. the ends of each track must be on the main pedestrian traffic routes; and
  2. the parallel tracks must have equal convenience and be located as close as practicable to the main pedestrian branch.

(3) The minimum unobstructed width of an accessway must be 1.2 m, except that—

  1. the minimum unobstructed width of a moving walkway forming part of an accessway may be not less than 850 mm; and
  2. the minimum unobstructed width of a doorway in an accessway may be not less than 850 mm.

(4) Poles, columns, stanchions, bollards and fixtures must not project into an accessway.

(5) Obstacles that abut an accessway must have a luminance contrast with a background of not less than 30%.

(6) Manoeuvring areas that allow a 180 degree wheelchair turn must comply with clause 6.2 of AS 1428.2.

(7) A passing area must be provided at least every 6 m along any two-way accessway that is less than 1800 mm wide.

(8) Ground and floor surfaces must comply with clause 9 of AS 1428.2 and AS 1428.1 Supplement 1 provides criteria for the selection of floor surfaces.

(9) The requirements of D4D4(c)(ii) do not apply to Class 9b or Class 10 public transport buildings.

Accessways and manoeuvring areas may be for other purposes, such as standing areas, but it is expected that public transport passengers will be able to transit them and that they remain available for use by people with a disability when required.

Hazards created by poles, columns, stanchions, bollards and fixtures alongside accessways must be avoided. For example, the use of short posts to prevent delivery vehicles from driving onto parts of pedestrian areas, or commercial signs projecting from walls should be avoided.

I2D2(7) requires passing areas to be provided in prescribed locations, with the intent that they be wide enough for 2 people, each using a mobility aid, to pass one another.
