Future
Key Issues
The
main works anticipated in the upcoming month are as follows:
● Excavation
● Bored pile
● Pre-drilling
● Temporary storage and treatment for
excavated marine sediment
To connect the Hong Kong-Zhuhai-Macao
Bridge (HZMB) Hong Kong Boundary Crossing Facilities (HKBCF) with the Hong Kong
International Airport (HKIA), roads including an elevated bridge structure
(hereinafter referred to as the HKBCF Viaduct/Roads) were proposed as part of
the HKBCF project, as described in Section 4.5 of the approved Environmental
Impact Assessment (EIA) report of the HKBCF project. The HKBCF Viaduct/Roads
are located partly within the boundary of the Airport Island near Terminal 2
(T2) and partly within the boundary of the land corridor between HKBCF and the
Airport Island, i.e., partly within the HKBCF boundary.
Under
the HKBCF project, the arrangements for the planning of the construction of the
HKBCF Viaduct/Roads were formulated based on the scenario with the existing
two-runway system (2RS) at the HKIA. The portion of the HKBCF Viaduct/Roads
falling within the boundary of the land corridor between HKBCF and HKIA were
originally planned to be constructed by Highways Department (HyD) of the Government of the Hong Kong Special
Administrative Region (HKSARG) as part of the HKBCF project.
With
the planned expansion of HKIA into a three-runway system (3RS), a revised
layout of the HKBCF Viaduct/Roads (the revised layout is hereinafter referred
to as the proposed HKIA-HKBCF Road Connection) was formulated as part of the
P282 Terminal 2 Expansion Design Consultancy of Airport Authority Hong Kong
(AAHK). The proposed HKIA-HKBCF Road Connection has taken the design of the 3RS
road network designed around the expanded T2 building into account. In addition
to preparing the detailed design, it was also considered that the proposed
HKIA-HKBCF Road Connection within the HKBCF boundary would be constructed by
AAHK instead of HyD along with the 3RS road network
planned within the Airport Island. Upon completion of the construction works,
the new HKIA-HKBCF Road Connection outside the Airport Island would be handed
over to HyD for future operation and maintenance.
The
EIA for the HKBCF project, which covered the HKBCF Viaduct/Roads as a
Designated Project (DP) based on the requirements set out in Item A.8. (i.e., a
road bridge more than 100 m in length between abutments) in Part 1 of Schedule
2 to the Environmental Impact Assessment Ordinance (EIAO) (Cap. 499), was
completed and approved (EIA Register No.: AEIAR-145/2009) and an Environmental
Permit (EP) (EP No.: EP-353/2009) was granted under the EIAO to HyD.
On the
other hand, the 3RS EIA had subsequently commenced and completed (EIA Register
No.: AEIAR-185/2014) by AAHK, and it has already taken the layout of the
proposed HKIA-HKBCF Road Connection into account and has assessed the relevant
cumulative environmental impacts. The planned change in implementation agent
from HyD to AAHK for the construction of the proposed
HKIA-HKBCF Road Connection outside the Airport Island would, involves a
transfer of corresponding responsibilities under the HKBCF EP from HyD to AAHK. To this end, an Environmental Review Report
(ERR) was prepared and submitted to Environmental Protection Department (EPD)
in November 2018 which concluded that the change of implementation agent from HyD to AAHK for the construction of HKIA-HKBCF Road
Connection would not result in any exceedance or violation of the environmental
performance requirements set out in the approved HKBCF and 3RS EIAs and the
mitigation measures identified in these EIAs remained relevant and valid. A
Further Environmental Permit (EP No. FEP-01/353/2009/K) for the construction of
the HKIA-HKBCF Road Connection (hereinafter referred to as the Project) was
granted to AAHK in December 2018 in accordance with Section 12 of EIAO.
Afterwards, an Environmental Monitoring and Audit Manual for HZMB HKBCF The
Road Connection between HKBCF and the Airport, Chek
Lap Kok (the EM&A Manual) has been prepared to
include appropriate environmental monitoring and audit (EM&A) requirements
in accordance with the information and recommendations described in the EIA
Report and by taking into account the specific site conditions of the Project
under the FEP.
The
Project consists of the construction of a road bridge more than 100 m in length
between abutments connecting between HKBCF and the HKIA which is part of the
work for HZMB-HKBCF. Location of the Project is shown in Figure
1.1.
Site
clearance and preparation works of the Project started in August 2021, and the
construction works commenced on 4 October 2021. The summary of construction
works programme can be referred to Section 1.4.
