Introduction
1.1
Background
1.1.1 MTR Corporation Limited (MTRCL) had commenced a study to formulate a
technically feasible development scheme for the Proposed Comprehensive
Residential and Commercial Development atop Siu Ho Wan Depot (hereinafter
referred to the “Oyster Bay (OYB) Property Development”) to optimize housing
supply. To facilitate the construction of the OYB Property Development,
railway related works would be required. The existing Siu Ho Wan Depot
(SHD) will undergo replanning works to make room for the phased construction of
the OYB Property Development, while maintenance and supporting services to the
existing Tung Chung Line (TCL), Airport Express Line (AEL) and Disneyland
Resort Line (DRL) should be maintained without causing disruption to the normal
operation. A new Oyster Bay (OYB) Station (formerly named as Siu Ho Wan
Station (SHO)) has also been proposed along the TCL tracks to meet transport
needs of the OYB Property Development and enable building of a sustainable
community.
1.1.2 The Environmental Impact Assessment (EIA) Report (Register No.:
AEIAR-214/2017) for the SHO and SHD Replanning Works
(hereafter referred to as the “Project”) was approved on 29 November 2017 under
the Environmental Impact Assessment Ordinance (EIAO). Following the
approval of the EIA Report, an Environmental Permit (EP) was granted on 22
March 2021 (EP No: EP-588/2021) for the construction and operation of the
Project.
1.2
Project
Programme
1.2.1 Four civil construction works contracts of the Project have been awarded
