Railway Know-it-all

January 2016

Different works activities can be carried out simultaneously at different locations, which is more efficient and time-saving when compared to other construction methods.

Highly efficient andsaves time

The construction of the pre-cast units will be carried out in a remote casting yard, and other related works activities including installation and connection will be carried out on the seabed of Victoria Harbour, so that the impact on the daily life of the public, marine traffic and the users of the CBTS is minimised.

Minimises impact on the public

By adopting the IMT construction method, the required area for temporary reclamation is reduced such that the impact on water and air quality is also minimised.

Cousin, how can trains run under the sea?

All cross-harbour tunnels in Hong Kong are built this way.

(2) Individual IMT pre-cast units are then lowered to the trench one by one and then connected up.

(3) Lastly, the trench is backfilled to bury the IMT.

Dredge hard!

Easy! Just lay a tunnel under

The Hung Hom to Admiralty Section of the Shatin to Central Link (SCL) will extend the existing East Rail Line from Hung Hom Station across Victoria Harbour to Admiralty Station, forming the “North South Corridor”. Passengers can travel from the heart of Hong Kong Island to Hung Hom, or even Lo Wu/Lok Ma Chau directly. The new cross-harbour rail tunnel will connect the Causeway Bay Typhoon Shelter (CBTS) and Hung Hom foreshore. This is the fourth cross-harbour rail tunnel in Hong Kong and will be mainly constructed by the immersed tube tunnel (IMT) method. IMT pre-cast units are being fabricated at the former Shek O Quarry. The 11 finished IMT units will be towed to Victoria Harbour for installation in mid-2017.

Former Police Officers’ Club Works SiteTo facilitate the construction of ventilation facilities for the SCL tunnels, demolition of the Police Officers’ Club was completed in December 2015. Upon completion of the project, the Club will be reinstated and integrated with the ventilation facilities of the SCL. Foundation works for the future ventilation facilities and Police Officers’ Club are underway. Construction of the Tunnel Boring Machine (TBM) launching shaft at the temporarily reclaimed land at CBTS was completed to facilitate the launch in the second quarter of 2016 of “Athena”, the first TBM for the Hong Kong Island Section, which was delivered in late January.

Wan Shing StreetBefore tunnel boring works commence, underground obstructions along the alignment must be removed. Diversion of underground utilities, bridge underpinning and ground stabilisation works along the tunnel alignment in the vicinity of Tunnel Approach Rest Garden continue. Temporary traffic arrangements are in place at Wan Shing Street to faciliate obstruction removal and ground treatment works.

Railway Tunnels from CBTS to Admiralty Station

Cross Harbour Section

Fenwick Pier StreetThe rail tunnel between Fenwick Pier Street and Admiralty Station will be constructed by a TBM from a launching shaft located near Fenwick Pier Street. Ground treatment and the construction of diaphragm walls for the launching shaft and cut and cover tunnel are underway.The water main replacement works between Fenwick Pier Street and Expo Drive were concluded in December 2015.

Former Shek O QuarryIMT pre-cast units are now being fabricated in the casting yardlocated at the former Shek O Quarry.

Construction Progress

CBTS BreakwaterTrench dredging works in Victoria Harbour continue in phases until 2017 to prepare for the installation of the IMT units. Pipe piling works will be carried out near the breakwater of CBTS in early 2016 to form a temporary wave barrier.

Former Wan Chai North Public Transport InterchangeThe construction of the temporary footbridge connecting Great Eagle Centre/ Harbour Centre with the Wan Chai Ferry Pier is on-going and targeted to be completed in the third quarter of 2016. After this, the existing footbridge would be demolished to make room for the construction of Exhibition Station. Temporary traffic management arrangements will also be implemented in phases along Convention Avenue, Fleming Road, Expo Drive East and Tonnochy Road commencing in the first half of 2016. The former Public Transport Interchange site is now a works site for Exhibition Station. Construction of the diaphragm walls of the station continues in order to facilitate the upcoming excavation works. Construction noise and vibration may be generated during the works. Monitoring points have been installed at buildings in the vicinity to closely monitor the construction works.With the completion of ground stabilisation works in Wan Chai Sports Ground in October 2015, construction of the diaphragm walls for Exhibition Station railway facilities at the corner of the sports ground commenced in November 2015.

Wan Chai Swimming Pool and Harbour Road Sports CentreTo vacate space for the construction of Exhibition Station, the original Wan Chai Swimming Pool and Harbour Road Sports Centre need to be reprovisioned. After testing and commissioning, the new swimming pool was handed over to the Leisure and Cultural Services Department and commissioned in October 2015. On the first floor level, there is a convenient connection to the footbridge system in Wan Chai North for all-weather access around the neighbourhood.The demolition of the original swimming pool commenced subsequently and was completed at the end of 2015. Construction of the new Sports Centre and Exhibition Station follows, with the former expected to be completed in the second quarter of 2017.

The SCL will extend the East Rail Line from Hung Hom Station to Hong Kong Island, providing an alternative route for passengers to cross the harbour. This will improve road traffic and relieve the traffic in Wan Chai North and Hung Hom, hence minimising air pollution and noise as well as enhancing road safety and quality of life.

This section of the SCL across Victoria Harbour is constructed by the immersed tube tunnel method. Fabrication of the IMT pre-cast units at the former Shek O Quarry has commenced. Construction and

installation of immersed tube tunnel requires high precision in engineering. In addition, to provide space for the works, there is on-going close coordination with users in the mooring area and fairway. The projects team will

strive to overcome the challenges to bring the fourth cross-harbour rail tunnel to completion as early as possible.

Works for the Hong Kong Island Section are in full swing. The original Wan Chai Swimming Pool, which was reprovisioned in October last year, was demolished in December to expand the works area for Exhibition Station and embark on the reprovisioning of the Harbour Road Sports Centre. This marks an important milestone of the SCL project. The first TBM for the Hong Kong Island Section, “Athena”, will be launched in the second quarter of this year to commence the tunnel boring works on the island.

Carrying out works in the hustle and bustle of Hong Kong Island and the Victoria Harbour is never short of challenges. Our project team will continue to maintain close communication with the Government and local stakeholders in order to minimise impact during the construction period. We look forward to timely project completion, providing our community with fast and convenient new rail services connecting Hong Kong Island, Kowloon and the New Territories.

Joy of Reading

An exhibition was also held at the podium level of Great Eagle Centre in Wan Chai between October 2015 and January 2016 to help the public understand more about the SCL project.

To facilitate the IMT works for the Cross Harbour Section, moorings within CBTS will be adjusted. Relevant stakeholders were consulted through public forums in December 2015 and January 2016.

The SCL links up the Hong Kong Island, Kowloon and the New Territories. On 16 January 2016, about 50 children and their families were invited to an SCL community activity in the Wan Chai District to enhance their knowledge in engineering and the SCL project amid fun. The SCL project team also donated hundreds of books for the children to share the joy of reading.

The fourth meeting of the Community Liaison Group for Exhibition Section was held on 2 September 2015, followed by two information seminars for tenants from commercial buildings at Wan Chai North. Progress of the construction works was presented at the meetings and concerns addressed.
