10 Conclusion
2.1.1.
“Wan Chai
Development phase II and Central-Wan Chai Bypass” and “Central-Wan Chai Bypass
and Island Eastern Corridor Link” (hereafter called “the Project”) are Designed
Project (DP) under the Environmental Impact Assessment Ordinance (Cap. 499)
(EIAO). The Environmental Impact
Assessment (EIA) Reports for Central-Wan Chai Bypass and
2.1.2.
The key purpose
of Wan Chai Development Phase II (WDII) is to provide land at Wan Chai North
and North Point for construction of the Central-Wan Chai Bypass and Island
Eastern Corridor Link (CWB). Land formed under the project will be developed as
a world-class waterfront promenade joining that at the new Central waterfront
for public enjoyment.
2.1.3.
There is a
compelling and present need for the CWB to provide relief to the very congested
2.2.1.
Design and Construction of Central – Wan Chai Bypass and Island Eastern
Corridor Link under the Project involves the construction and operation of a
trunk road and its road tunnel more than 800m in length between portals that is
shown at Figure 2.1.
2.2.2.
The study area encompasses existing
developments from Central to North Point. The scope of the Central-Wanchai Bypass (CWB)
and Island Eastern Corridor Link (IECL) includes:
·
A dual
three-lane trunk road, approximately 4.5 km in length, and tunnel approximately
3.7 km in length defined from the connection with the existing Rumsey Street
Flyover in Central, through to a connection with the existing Island Eastern
Corridor to the east of the Causeway Bay Typhoon Shelter (CBTS);
·
The
Central Interchange near the Rumsey Street Flyover to provide road connections
to the Central area;
·
Tunnel
control buildings and ventilation buildings;
·
Slip
roads to connect the CWB to the local road system in the Wan Chai North and
·
Associated
road lighting, road signing, traffic control and surveillance system; and
·
Other
associated works.
2.2.3.
The project also
contains various Schedule 2 DPs that, under the EIAO, require Environmental
Permits (Eps) to be granted by the DEP before they may be either constructed or operated. Table 2.1 summarises the
five individual DPs under this Project. Figure 2.1 shows the locations of these Schedule 2 DPs.

Due to the
multi-contract nature of the Project, there are a number of contracts
sub-dividing the whole works area into different work areas to be
commenced. Contractors of individual
contracts will be required by the EP holder to apply Further Environmental
Permits such that the impact monitoring
stations are sub-divided accordingly to facilitate the implementation of
EM&A programme and to streamline the EM&A reporting for individual FEP
holders correspondingly.

In the reporting
month, Central-Wanchai Bypass – Tunnel (Causeway Bay Typhoon Shelter Section)
was commenced on 13 July 2011. The details of individual contracts are summarized in Table2.2.

out the noise monitoring. Immediately prior to and following each noise
measurement the accuracy of the sound level meter shall be checked using an
acoustic calibrator generating a known sound pressure level at a known
frequency. Measurements may be accepted as valid only if the calibration level
from before and after the noise measurement agree to within 1.0 dB.
4.1.9.
Noise
measurements shall not be made in fog, rain, wind with a steady speed exceeding
5 m/s or wind with gusts exceeding 10 m/s. The wind speed shall be checked with
a portable wind speed meter capable of measuring the wind speed in m/s.
4.1.10. The sound level meter shall be checked using an
acoustic calibrator generating a known sound pressure level at a known
frequency before deployment to the site and during each site visit.

and a police officer arrived to Contract HK/2009/01 site at about 6:30 a.m. on
6 November 2011 to inspect noise generated from the site and stop the existed machines
operation. The subcontractor for Diaphragm wall, SAMBO Korean foreman stopped
the engine of the BC cutter immediately. The police officer recorded the
details and HKID number of the foreman and then left. Due to the different
language communication between the police officer and the Korean foreman, no
CNP was checked by the police officer.
9.0.6.
According to the information reported by Contractor,
one BC cutter and a hoist were operated for inspecting all bentonite pipes were
in good condition and all joints were tightened in good position for Diaphragm
Wall construction of Shatin-Central Link. Due to insufficient communication
between Contractor HK/2009/01 and their Korean Sub-contractor, the Korean
Sub-contractor had not notified to Contractor prior carrying out the inspection
of the bentonite pipes and all pipe joints to ensure no damages and was tightened
in good positions at about 6:00a.m.
