7.0.1. According
to the Condition 3.4 of the EP-376/2009, 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 month.
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 November 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, demolition of Contract no.HK/2009/02 site office 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 was modification works at Central; seabed reinstatement at Causeway
Bay, drainage improvement work and utility diversion works at Victoria Park;
bridge noise enclosure installation works, road works, drainage works, soft
