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

conducted under Contract HY/2010/08 near Victoria Park Swimming Pool (Hing Fat
Street) during the restricted hours (from 1900hrs to 0700hrs on the following
day) across the period from 13 February 2017 to 21 February 2017.
Based on the site
records confirmed by RSS, no works was conducted under Contract HY/2010/08 near
Victoria Park Swimming Pool (Hing Fat Street) during the restricted hours (from
1900hrs to 0700hrs on the following day) from 13 February 2017 to 20 February
2017. Concreting of tunnel structure at Temporary Reclamation Area TS3 was conducted
under Contract HY/2010/08 between 1900hrs and 2300hrs on 13, 14, 15, 16 and 18
February 2017 and total 3 nos. of concrete pumps and 6 nos. of concrete lorry
mixers were operated. Concreting of tunnel structure at Temporary Reclamation
Area TS3 were conducted under Contract HY/2010/08 between 1900hrs and 2100hrs
on 21 February 2017 and total 3 nos. of concrete pump and 6 nos. of concrete
lorry mixers were operated. Relevant Construction Noise Permit GW-RS0029-17 was
in place while it is considered that there is no sufficient information to
indicate whether the Powered Mechanical Equipment were deployed at the designed
location stipulated under the relevant Construction Noise Permit with noise
mitigation measures required.
Concreting of
tunnel structure at Zone C was conducted under Contract HY/2010/08 between
1900hrs to 2300hrs on 17 and 20 February 2017. Total 1 no. of concrete pump and
2 nos. concrete mixers were operated. Bar bending at Zone C was conducted under
Contract HY/2010/08 between 1900hrs to 2300hrs on 13, 14, 15, 16, 18 and 19
February 2017 and total 1 no. bar bender and cutter was operated. Relevant
Construction Noise Permit GW-RS1366-13 was in place while it is considered that
there is no sufficient information to indicate whether the Powered Mechanical
Equipment were deployed at the designed location stipulated under the relevant
Construction Noise Permit with noise mitigation measures required.
Nevertheless,
further to the joint ad-hoc inspection conducted by the ET/IEC on 13 February 2017
during restricted hours (between 1900hrs to 2200hrs), concurrent operations of
4 nos. of concrete lorry trucks at the Southern Side of TS3 near Construction
Site Entrance and concurrent operations of 2 nos. of concrete lorry pumps and 2
nos. of concrete lorry truck at Western and Northern Side of TS3 were observed
while the temporary noise barrier provided for the concrete lorry pump and
concrete lorry truck at the Northern Side of TS3 could not screen entirely the
concrete lorry truck and concrete lorry pump (Located at Northern Side of TS3)
from nearby sensitive receivers. Therefore, it is considered that the above
operations observed could not follow the PME grouping requirement and the
specific condition 3.d.4 under the relevant Construction Noise Permit.
In view of the
above, the Contractor of HY/2010/08 was advised to enhance the site supervision
and strictly implement the site control system for construction works carried
out during restricted hours to ensure the PMEs deployed strictly comply with
relevant Construction Noise Permit. The Contractor of HY/2010/08 was also
reminded to maintain regular maintenance of the plant and equipment deployed to
avoid potential nuisance to the nearby public.
