Road
Repair Work
The
road repair work was carried out at the junction of Cheong Wan Road
and the podium of KCR Hung Hom Station.
Environmental
Concern
In
view of the heavy traffic, it was impossible to carry out
the works through lane-by-lane closure at the junction during
the daytime. Eventhough the closest noise sensitive receivers,
i.e. the residential buildings on Winslow Street, were about
280 m away from the work area, the noise generated from the
electric handheld breaker and the petrol concrete saw during
the night-time noise sensitive hours was a major concern.

Measures
Adopted
Enclosure
- To minimise the noise impact, a double enclosure made of
steel with the inner shed lined with a 50 mm thick sound absorbing
material was fabricated to minimise the noise impact from
the road-breaking work. |
Observations
& Achievements
Without
any mitigation measure, the noise level from the electric handheld
breaker & the concrete saw would be about 60dB(A) at the noise sensitive
receivers identified. Such night time operation would seriously
affect the residents. Through adoption of the double enclosure,
the residents at Winslow Street were protected. No complaints were
received against noise from the works.
