Section 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 Island Eastern Corridor Link (Register No.
AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai Bypass
(Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and 11
December 2008 respectively.
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 east-west Connaught Road Central/Harcourt
Road / Gloucester Road Corridor (the Corridor) which is currently operating
beyond its capacity. The CWB will provide relief to the existing congestion
along the Corridor and cater for the anticipated growth of traffic on Hong Kong
Island. Without the CWB and its access roads, there will not be sufficient
capacity to serve the heavy traffic demands at both strategic and local levels.
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 Causeway Bay area;
 -
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.
2.3.2.
In the reporting month, Central-Wanchai Bypass  Tunnel
(Causeway Bay Typhoon Shelter Section) was commenced on 13 July 2011. The details of individual

4.1.4.
The construction noise level shall
be measured in terms of the A-weighted equivalent continuous sound
pressure level (Leq). Leq (30 minutes) shall be used as
the monitoring parameter for the time period between 0700
and 1900 hours on normal weekdays. For all other time periods, Leq (5
minutes) shall be employed for comparison with the Noise Control
Ordinance (NCO) criteria. Supplementary information for
data auditing, statistical results such as L10 and L90
shall also be obtained for reference.
4.1.5.
Noise monitoring shall be carried out at all
the designated monitoring stations. The monitoring frequency shall depend on
the scale of the construction activities. The following is an initial guide on
the regular monitoring frequency for each station on a weekly basis when noise
generating activities are underway:
 -
One set of measurements between 0700 and 1900
hours on normal weekdays.
4.1.6.
Real time noise shall be carried out at the
designated monitoring stations. The following is an initial guide on the

 -
One set of measurements between 0700 and 1900
hours on normal weekdays.
 -
One set of measurements between 1900 and 2300
hours on normal weekdays and 0700 and 2300 hours on public holidays.
 -
One set of measurements between 2300 and 0700
hours on next day on everyday.
4.1.7.
If construction works are extended to include
works during the hours of 1900  0700 as well as public holidays and Sundays,
additional weekly impact monitoring shall be carried out during respective
restricted hours periods. Applicable permits under NCO shall be obtained by the
Contractor.

Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type
1) specifications shall be used for carrying 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. Measurements July be accepted as valid only if the
calibration level from before and after the noise measurement agree to within
1.0 dB.

general filling works in IRAE; Wan Chai Development Phase II was marine works
at HKCEC areas, cross-harbour Watermains, Fresh Watermains, Cooling Watermains
and Salt Watermains Installations, tunnel works at Wan Chai East, seawall block
construction, reclamation work and diaphragm wall construction at TS4; Diaphragm
wall construction at TS1 and TPCWAE TCBR1W. Advanced piling works at FEHD
Whitfield Depot, Central Interchange, and diaphragm wall construction at North
Point area. The major environmental impact was water quality impact at Causeway
Bay and Wan Chai. Land-based construction activity were advance filling works
at TS4, Diaphragm wall construction at TS1 and TPCWAE TCBR1W,
piling works at FEHD Whitfield Depot, Diaphragm wall at Central and North Point
