MOD 5 - Blues Point Acoustic Shed

Submission regarding Sydney Metro City and Southwest
MOD 5, Blues Point Temporary Retrieval Site.

I support the construction and use of an Acoustic Shed to minimise
noise and dust impacts on residents.

Point 3.2. Design of shed. This indicates ventilation louvres will be
on the "north wall' of the shed. If the ventilation louvres will allow
more noise egression from machinery and ventilation fans then walls
without louvres, the louvres should be moved and located on the south
face - which faces the construction site and park area (100m distant)
and harbour rather than the north face which faces nearby apartment
buildings and houses and will concentrate the noise between the shed
and the adjacent Henry Lawson Drive Sandstone cutting, almost
certainly creating a higher noise impact than planned. Additionally,
noise directed south will be partially reflected away from the Blues
Point Tower and other buildings by the high sandstone cutting to the
west of the shed.

Point 8.2 Mitigation Measures - Noise and Vibration; states that plant
will be kept as far from 'receivers' (presumably people) as possible.
Again, if ventilation plant is on the northern wall of the shed, it
will be very close to 'receivers'. Locating it on the southern face of
the shed maximises the separation distance of the plant from
'receivers'.
