4.1.1
The
proposed cross harbour water mains will extend from Wan Chai near the HKCEC
Extension to connect to the existing system near the Museum of Arts
at the Tsim Sha Tsui promenade. The
noise sensitive receivers located within 300m
of construction sites at Wan Chai and Tsim Sha Tsui are basically the buildings
equipped with central air-conditioning system. The
first layer of NSRs near Tsim Sha Tsui site, which are centrally
air-conditioned, would provide considerable acoustic shielding to those
receivers at further distance behind.
4.1.2
The
existing NSRs close to the construction sites at Wan Chai and Tsim Sha Tsui are
the HKCEC Extension, the Hong Kong Space Museum
and the Museum of
Arts. Since they have blank facades / fixed
windows and are provided with central air conditioning (i.e. they do not rely
on openable windows for ventilation), no adverse construction noise impacts on
the indoor environment of these existing NSRs would be anticipated.
4.1.3
According
to the normal practices adopted for similar land uses in Hong
Kong (e.g. existing HKAPA), the HKAPA Extension would be provided
with central air-conditioning system and it does not rely on openable window
for ventilation. Thus, no adverse construction noise impacts on the indoor
environment of this planned NSR would be anticipated.
4.1.4
In
view of the project nature, no adverse noise impact during the operation phase
would be anticipated.
4.1.5
While construction noise monitoring
would not be considered required for this DP, a weekly site inspection shall be
carried out throughout the construction phase to ensure that appropriate noise
control measures would be properly implemented with a view to minimizing the
construction noise impact.
