The ITA
Tunnelling Awards 2016: Highlight on category “Major Project of the year with a
budget over €500m”
Introducing
4 remarkable projects:
Lausanne,
30th of August 2016.- The ITA Tunnelling Awards is a prestigious competition
which intends to identify outstanding achievements in the field of tunneling
and underground space development, and provide international recognition to
these remarkable contributions. This second edition is hosted in Singapore, the
10th & 11th November and includes 9 categories*.
The
first category in this worldwide competition: “Major Tunnelling Project of the
Year – over 500M€” is composed of large-scale infrastructure projects. In 2015,
the “Eurasia Tunnel Project” was awarded in this category. This year, among 13
projects received for this category, four caught the attention of the panel of
judges:
– WAN CHAI BYPASS AND
ISLAND EASTERN CORRIDOR LINK – CAUSEWAY BAY TYPHOON SHELTER SECTION – application from Hong-Kong
Central,
Causeway Bay and Wan Chai lie in the heart of Hong Kong and are heavily
trafficked. Hence there is a compelling need to provide a new trunk road to
relieve the existing traffic congestion and cater for the anticipated traffic
growth. The CWB expressway – a 4.5km dual 3-lane “Central – Wan Chai Bypass and
Island Eastern Corridor Link (CWB)” will allow relieving the congestion between
the east-west along the northern shore of Hong Kong Island and coping with
predicted traffic.
Causeway
Bay Typhoon Shelter Section, as part of the CWB project, mainly comprises
construction of approximately 750m of tunnel under the sea-bed between the
ex-Wan Chai Public Cargo Working Area (ex-PCWA) and the east breakwater of
Causeway Bay Typhoon Shelter (CBTS).
The
construction of this 750m tunnel under the sea-bed took into account the
geographic and spatial constraints and operational requirement of the existing
facilities. Different construction techniques have been adopted, including
“Cut-and-cover” through temporary reclamation for the section under ex-PCWA and
CBTS; and “drill-and-break” for the section (The Mined Tunnel) underneath the
existing Cross Harbour Tunnel (CHT).
• KLANG VALLEY MASS RAPID TRANSIT – SBK LINE – application
from Malaysia
In Malaysia, Klang Valley (which
includes Kuala Lumpur and adjoining cities and towns from the state of
Selangor) is home to some seven million people, with an expected increase to 10
million by 2020. This translates to about 18 million trips a day in the Klang
Valley which, using private vehicles, would cause all roads in the Klang Valley
to be gridlocked throughout the day.
With
a vision to make Kuala Lumpur move up the notch to settle amongst the 20 top
most liveable cities in the world, the government of Malaysia engaged into the
first Mass Rapid Transit project: a modern urban rail that will serve people of
the greater Kuala Lumpur. The Mass Rapid Transit, together with the existing
urban rail network, will form the backbone of the public transport system in
the Greater Kuala Lumpur/Klang Valley region.
The
Klang Valley Mass Rapid Transit (KVMRT) Project involves the construction of a
rail-based public transport network comprising three lines (Two new and the
previous existing one).
The
first line to be implemented is the 51km Sungai Buloh-Kajang Line (SBK Line).
Construction of the line began on 8 July 2011. The Sungai Buloh – Serdang –
Putrajaya line (SSP line) will be the second MRT line to be developed.
• SINGAPORE POWER CROSS – ISLAND CABLE TUNNEL PROJECT –
application from Singapore
Singapore
Power (SP) owns and operates Singapore’s electricity and gas transmission and
distribution businesses catering to 1.4 million industrial, commercial and
domestic customers. To ensure continual reliable, secure and quality power
supply and meeting future demand, SP engaged into a major tunnel infrastructure
criss-crossing the island nation North-South and East-West.
The
average 60m deep, 35km long tunnel will house the 400kV and 230kV transmission
cable to overcome the existing congestion of underground space and utility
services where it is no longer feasible to install multiple transmission cables
over long distances by conventional direct burial. Once completed, the tunnels
will enable an efficient and reliable electricity network, faster maintenance
and replacement of cables thereby contributing to economic competitiveness and
ensuring better quality of life for all.
• THE NEW GUANJIAO TUNNEL ON QINGHAI-TIBET RAILWAY –
application from China
The
New Guanjiao Tunnel is a key project of the second line of Xining-Golmud
section of Qinghai-Tibet Railway with a total length of 32.690km. The project
aims to address the problems of difficult operation and low efficiency where
the existing railway climbs over Mount Qinghai Nanshan. The tunnel runs between
Tianpeng station and Chahannuo station within the Territory of Tianjun County
and Wulan County of the Qinghai province. Construction began on 6th November,
2007 and the tunnel was opened to revenue service on 28th December, 2014.
It
is the first time that a tunnel of over 30 km length is built in an area of
over 3000m elevation with complex geological conditions due to magmatic rock,
sedimentary rock and metamorphic rock. The new tunnel, a two-set single-track
tunnel, operates with freight and passenger electrified railway with a design
speed of 160km/h, double-block ballastless track, seamless rail, rigid
suspension catenary, and four-aspect automatic block signal system. The
facilities include a 550m long emergency rescue station in the middle of the
tunnel, together with 85 cross passages outside the emergency rescue station,
for operation safety.
