PO40.1 Development (excluding a relevant residential building or relocated building) provides a noise
barrier or earth mound is provided 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;

         In accordance with Table 1 the acoustic levels are:

              c) ≤60 dB(A) L10 (18 hour) façade corrected (measured L90 (8 hour) free field between
                 10pm and 6am ≤40 dB(A));

         OR

              d) ≤63 dB(A) L10 (18 hour) façade corrected (measured L90 (8 hour) free field between
                 10pm and 6am >40 dB(A))

    2. in accordance with:
           a. chapter 7 integrated noise barrier design of the Transport Noise Management Code of
               Practice: Volume 1 (Road Traffic Noise), Department of Transport and Main Roads,
               2013;
           b. Technical Specification-MRTS15 Noise Fences, Transport and Main Roads, 2019;
           c. Technical Specification-MRTS04 General Earthworks, Transport and Main Roads,
               2020;

         OR

AO40.2 Development (excluding a relevant residential building or relocated building) achieves the
maximum building facade acoustic level in reference table 1 (item 1.1) for habitable rooms by alternative
noise attenuation measures where it is not practical to provide a noise barrier or earth mound.

PO41 Habitable rooms (excluding a relevant residential building or relocated building) are designed
and constructed using materials to achieve the maximum internal acoustic level in reference table 3
(item 3.1).

In accordance with Table 3 the acoustic level is ≤35 dB(A) Leq (1 hour) (maximum over 24 hours).

NOTE: Facade correction is +2.5 dB(A) to the free field result.



Above ground floor level requirements (accommodation activity) adjacent to a state controlled
road

PO42 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.

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

Additionally, habitable rooms within a transport noise corridor must comply with the Queensland
Development Code MP4.4, Buildings in a Transport Noise Corridor.
