7.0.1. This
section addresses the relevant cumulative construction impact due to the
concurrent activities of the current projects including the Central Reclamation
Phase III (CRIII), Wan Chai Development Phase II (WDII), Central-WanChai Bypass
(CWB), Island Eastern Corridor Link projects (IECL) and Wan Chai Development
Phase II – Central – Wan Chai Bypass at Wan Chai East (CWB Tunnel).
7.0.2.
According to the Monthly EM&A reports (October,
November and December 2013) of Central Reclamation Phase III
(CRIII) for Contract HK 12/02, remaining soft landscaping work behind GPO
boundary wall, remaining footpath construction at Edinburgh Place, installation
of directional sign at Road P2, removal of two existing E&M drawpits at
East Bound Road P2 near Road D8 and additional surface drain at ACL CER office
compound were performed in the reporting period. The water
quality monitoring was completed in October 2011 and no Project-related exceedance
was recorded for air and noise monitoring.
It can be concluded that cumulative construction impact due to the
concurrent activities of the current projects with the Central Reclamation
Phase III (CRIII) undertaken by contractor HK12/02 was insignificant.
7.0.3. According
to the construction programme of Wan Chai Development Phase II, Central-Wan
Chai Bypass and Island Eastern Corridor Link projects, the major construction
activity under Wan Chai Development Phase II were marine works at HKCEC areas,
cross-harbour Watermains, Fresh Watermains and Cooling Watermains Installations,
tunnel works at Wan Chai East. The major construction activities under
Central-Wan Chai Bypass and Island Eastern Corridor Link Projects were ELS work, tunnel
water proofing works and tunnel construction at TS4 and cut and cover
tunnel construction and dismantling of struts at TPCWAE. Bridge construction and
tunnel works at Central Interchange, ELS segment launching works and IEC
parapet demolition at North Point area. The major
environmental impact was water quality impact at Causeway Bay and Wan Chai.
Land-based construction activities were excavation, tunnel
works at TS2, ELS work and water proofing works, tunnel construction at TS4 and cut
and cover tunnel construction and dismantling of struts at TPCWAE, tunnel
works at Central and ELS work at North Point and tunnel works at Wan Chai East
in the reporting period.
7.0.4. The major
environmental impacts generated from tunnel works at Central and tunnel works
at Wan Chai East, IECL and Causeway Bay Typhoon Shelter were undertaken in the
reporting period. No significant air impact from construction activities was anticipated
in the reporting period. Besides, no project-related exceedances were recorded
during the air and noise environmental monitoring events in the reporting
period. Thus, it is evaluated that the cumulative construction impact from the
concurrent projects including Wan Chai Development Phase II was insignificant.
8.0.1. The EM&A programme was carried out
in accordance with the EM&A Manual requirements, minor alterations to the
programme proposed were made in response to changing circumstances.
8.0.2. No non-compliances were noted and no
prosecutions were received during the reporting period.
8.0.3. The
construction programmes of individual contracts are provided in Appendix 8.1.
