The South Island Line (East) (SIL(E)) is a medium capacity railway approximately 7km long with stations at Admiralty (ADM), Ocean Park (OCP), Wong Chuk Hang (WCH), Lei Tung (LET) and South Horizons SOH). It is the first rail corridor on the southern side of Hong Kong Island linking it to the existing Hong Kong Rail Network. The new South Island Line started operating on 28 December 2016, serving the 350,000 residents and workers in Southern District.
Atkins was commissioned in May 2009 to design the two elevated stations at WCH and OCP, in addition to a new 250m Aberdeen Channel Bridge and 1.8km of Viaduct. The works also included the enhancement of Staunton Creek Nullah (a large box culvert), up-grading of slopes, designing complex utility diversions, landscaping, traffic and highways design.
Atkins was awarded the detailed design consultancy C903 comprising two of the five new stations at Ocean Park and Wong Chuk Hang, both elevated. The scope also covered a new 247m bridge spanning the Aberdeen Channel and 1.9km of new elevated viaduct, the enhancement of Staunton Creek Nullah (a large box culvert), up-grading of slopes, designing complex utility diversions, landscaping, traffic and highways design, and other associated works.
Following the award of the 903 Target Cost Works Contract to Leighton, Atkins was further engaged to redesign the viaducts and bridge to suit the contractor’s selected erection sequence and pre-stressing configurations.
A key aspect of the design was the management of the approvals process to ensure that all the necessary approvals, consents and permits were obtained to enable the construction works to proceed in accordance with the employer’s programme. With over 350 design submissions all requiring approval and/or consent from various authorities, this presented a significant logistical and management challenge which had to be effectively managed to meet the client’s implementation programme.
