RSS confirmation of construction works completion on 1 April 2020 and agreed
with IEC on 3 April 2020, the weekly environmental site inspection for Contract
no. HK/2012/08 under EP-376/2009 was suspended from 3 April 2020 onward.
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 August 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.
