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 Final EM&A report of Central Reclamation Phase III (CRIII) for
Contract HK 12/02, the major construction activities were completed by end of
January 2014 and no construction activities were undertaken thereafter and the
water quality monitoring was completed in October 2011. As such, it is considered that there were no
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 in the reporting period.
7.0.3.
According
to the construction programme of Central-Wanchai Bypass at Wanchai West at the
Central Reclamation Phase III area, no works was conducted in July 2020
reporting period. In view of the above, the cumulative construction impact due
to the Central Reclamation Phase III (CRIII) was not anticipated.
7.0.4.
According to the construction programme of
Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern
Corridor Link projects, no construction works under Wan Chai Development Phase
II was conducted at Wan Chai. The major construction activities under
Central-Wan Chai Bypass and Island Eastern Corridor Link Projects were
ventilation building ABWF works and modification works at Central; drainage
improvement work and utility diversion works at Victoria Park; bridge noise
enclosure installation works, road works, drainage works, soft landscape works
and ventilation building ABWF work at North Point area in the reporting period.
In addition, other non-Wan Chai Development Phase II, Central-Wan Chai Bypass
and Island Eastern Corridor Link projects were observed undertaken at Wan Chai
North and North Point area.
7.0.5.
As
relevant site mitigation measures for air quality and construction noise were
implemented, no significant air quality impact and noise impact from
construction activities was concluded in the reporting period. Besides, no
construction work was conducted at EP-122 area in the reporting period. Thus,
it is evaluated that the cumulative construction impact from the concurrent
projects including Wan Chai Development Phase II (WDII), Central- WanChai
Bypass (CWB), Island Eastern Corridor Link projects (IECL) 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. Termination of EM&A programme
(Construction Period) under EM&A Manual section 8.5.1 & 8.5.2 is in
progress.
8.0.4. The
construction programmes of individual contracts are provided in Appendix 8.1.
