    AO41.2 Development achieves the maximum free field acoustic levels in reference table 2 (item
    2.2) for private open space at the ground floor level by alternative noise attenuation measures
    where it is not practical to provide a noise barrier or earth mound.

PO42 Development (excluding a relevant residential building or relocated building) minimises noise
intrusion from a railway in habitable rooms at the facade of the ground floor level.

AO42.1 Development (excluding a relevant residential building or relocated building) provides a noise
barrier or earth mound which is designed, sited and constructed:

    1. to achieve the maximum building facade acoustic level in reference table 1 (item 1.1) for
       habitable rooms at the ground floor level:

    2. in accordance with:

              a. Civil Engineering Standard Specification QR-CTS-Part41 – Part 41, Design and
                 Construction of Noise Fences/Barriers, Queensland Rail 2018;

              b. Technical Specification MRTS15 Noise Fences, Transport and Main Roads, 2019;

              c.   Technical Specification MRTS-4 General Earthworks, Transport and Main Roads, 2020.

    OR:

    AO42.2 Development (excluding a relevant residential building or relocated building) achieves the
    maximum building facade acoustic levels in reference table 1 (item 1.1) for habitable rooms at the
    ground floor level by alternative noise attenuation measures where it is not practical to provide a
    noise barrier or earth mound.



PO43 Habitable rooms (excluding a relevant residential building or relocated building) are designed and
constructed using materials to achieve the maximum internal acoustic level in Table 3 (item 3.1).

Above ground floor level requirements adjacent to a railway or Type 2 multi-modal corridor:

PO44 Balconies, podiums and roof decks include:
   1. a continuous solid gap-free structure or balustrade (excluding gaps required for drainage
      purposes to comply with the Building Code of Australia);
   2. highly acoustically absorbent material treatment for the total area of the soffit above balconies,
      podiums and roof decks.

PO45 Habitable rooms (excluding a relevant residential building or relocated building) are designed and
constructed using materials to achieve the maximum internal acoustic level in Table 3 (item 3.1).

The single event maximum sound level is the arithmetic average of the 15 highest train passby noise
levels for a 24-hour period.

Table 1, Item 1.1 states the following rail noise limits:
