           landscape buffer strips, environmental areas or corridors, or conservation areas or
           corridors.
          Residential building means a class 1, class 2, class 3 or class 4 building as defined in
           the Building Code of Australia.
          Type 1 multi-modal corridor means a transport corridor that includes a state-controlled
           road and at least one of the following – busway, light rail and/or railway with 15 or less
           passing trains per day.

4.2.3      Rail Noise Criteria

For ‘Residential development near a railway (with more than 15 passing trains per day) or a type
2 multi modal corridor’, the relevant Performance Outcome (PO) is PO2 ‘Development involving
an accommodation activity achieves acceptable noise levels for residents and visitors by
mitigating adverse impacts on the development from noise generated by a railway with more
than 15 passing trains per day or a type 2 multi-modal corridor’. The Acceptable Outcomes (AO)
are as follows:
AO2.1 All facades of an accommodation activity exposed to noise from a railway with more than
15 passing trains per day or a type 2 multi-modal corridor meet the following external noise
criteria:
           (1) ≤65 dBA Leq(24 hour) facade corrected
           (2) ≤87 dBA (single event maximum sound pressure level) facade corrected.
AND
AO2.2 Every private open space and passive recreation area in an accommodation activity
exposed to noise from a railway with more than 15 passing trains per day or a type 2 multi-
modal corridor meet the following external noise criteria:
           (1) ≤62 dBA Leq(24 hour) free field.
           (2) ≤84 dBA (single event maximum sound pressure level) free-field.
AND
AO2.3 Every habitable room in an accommodation activity exposed to noise from a railway with
more than 15 passing trains per day or a type 2 multi-modal corridor meet the following internal
noise criteria*:
           (1) ≤45 dBA single event maximum sound pressure level (railway).


Notes: Noise levels from railways or type 2 multi-modal corridors are to be measured in
       accordance with AS1055.1–1997 Acoustics – Description and measurement of
       environmental noise.
           * ASK has been advised by SARA on 03/12/13 that it is acceptable to design residential
           buildings beside a rail corridor to MP4.4 even if the rail corridor has not yet been
           mapped as a transport noise corridor.


4.3       Department of Housing and Public Works – MP4.4

The Department of Housing and Public Works (HPW) has a number of mandatory Codes that
must be complied with at building application stage. These are referred to as Queensland
Development Codes (QDC). These codes previously only related to items such as energy
efficiency and water efficient fixtures in new residences.
