Section 8 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.

2.3.1. 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 period, all the contracts
were commenced and contract no. 04/HY/2006 had been completed. The details of individual contracts are summarized

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.
3.1.4.
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.
3.1.5.
Real time noise shall be carried out at the designated
monitoring stations. The following is an initial guide on the regular
monitoring frequency for each station on a 24 hours daily basis when noise
generating activities are underway:
·
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.
3.1.6.
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.
Monitoring Equipment
3.1.7.
As referred to in the Technical Memorandum ™
issued under the NCO, sound level meters in compliance with the International
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.
3.1.8.
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.
3.1.9.
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 may be accepted as valid only if the calibration level from before
and after the noise measurement agree to within 1.0 dB.
