Downtown Line Stage 3 – Contract 935Singapore

Downtown Line Stage 3 is a key component of

Singapore’s 42-kilometre long Downtown Line and

extends the existing Mass Rapid Transit railway

network. The project includes the construction of Jalan

Besar Station, which is a four-level station box with a

platform, mezzanine, concourse and linkway, as well

as related civil, structural, architectural, plumbing,

drainage, landscaping and reinstatement works. Twin

tunnels approximately 775 metres in length between

Jalan Besar Station and Bencoolen Station are being

built using two tunnel-boring machines. Jalan Besar

Station, which is located where Jalan Besar and Weld

Road intersect and is adjacent to Sim Lim Tower,

serves many shops and businesses around the area.

10 11Rail Rail

Guangzhou-Shenzhen-Hong Kong Express Rail Link (XRL)Hong Kong

Reinforcing Hong Kong’s status as a transport hub and international

gateway to China, the cross-boundary Guangzhou-Shenzhen-Hong Kong

Express Rail Link (XRL) provides high-speed rail service to Guangdong

Province and major mainland cities through the national high-speed rail

network. As one of Hong Kong’s most significant railway projects, the XRL

extends underground for about 26 kilometres in the city and provides fast,

convenient and reliable passenger service between the terminus in West

Kowloon and the border.

For the development of a world-class rail terminus building, we are

constructing the northern portion of the West Kowloon Terminus Station,

which includes nine long-haul and six shuttle platforms, customs and

immigration facilities, departure lounges, duty free and other retail outlets

and features a dramatic steel and glass roof structure above the entrance.

We are also designing, manufacturing, supplying, installing and testing fire

services, plumbing and drainage at the West Kowloon Terminus Station.

In addition, we are responsible for two key underground sections. For the

7.65-kilometre long section between Tse Uk Tsuen and Shek Yam, we are

constructing tunnels and ventilation buildings, including 5.08 kilometres

of twin-track tunnels, a pair of single-track tunnels, ventilation buildings

at Shing Mun and Pat Heung as well as temporary magazines for storing

explosives at Tai Shu Ha and So Kwun Wat.

This project introduced Hong Kong to many new techniques, especially

for blasting. We monitored the level of construction noise and vibration,

regularly tested the water and air quality around the area and actively

engaged neighbouring communities to keep residents aware of the project’s

progress. To reduce wastage, we processed excavated rock for use in a

drainage layer under the invert of the tunnel. We are also constructing a

311-metre long approach tunnel, a 121-metre long track fan tunnel, a public

transport interchange, two footbridges, a 300-metre long road underpass

and other works.

12 13Rail Rail

The South Island Line (East) is a medium-capacity

railway covering approximately 7 kilometres from

Admiralty Station to South Horizons in Ap Lei Chau,

with intermediate stations at Ocean Park, Wong Chuk

Hang and Lei Tung. Our work involves the construction

of two elevated stations at Ocean Park and Wong

Chuk Hang and two underground stations at Lei

Tung and South Horizons. For the elevated stations,

we are constructing 2.1 kilometres of viaduct that

South Island Line (East)Hong Kong

forms the above ground section of the railway and a

246-metre long bridge over the Aberdeen Channel.

The new station at Ocean Park connects to the

entry plaza of the marine theme park via an elevated

walkway while the one at Wong Chuk Hang is built

with a public transport interchange underneath. The

underground stations include tunnels and related plant

and ventilation buildings. The new station at Lei Tung

is constructed by drilling and blasting and includes

two pedestrian access adits and a vertical shaft.

The one at South Horizons is built using cut-and-

cover construction methods. Our work includes 1.1

kilometres of drill-and-blast tunnelling, 200 metres of

cut-and-cover tunnelling, access adit construction and

two rock slopes that need to be cut to construct plant

and ventilation buildings.

Road

Our land transportation systems cover

thousands of kilometres to connect

communities across the region with

new expressways, upgraded toll roads

and more. With urban populations and

car ownership on the rise in Asia, we

understand the importance of delivering

road transportation systems and facilities

that enable people to travel efficiently,

safely and reliably.

16 Road

Manila North Tollways ProjectPhilippines

The North Luzon Expressway is an 84-kilometre long

toll expressway running between Balintawak in Quezon

City and Santa Ines in Pampanga. Upgraded, expanded

and rehabilitated to US interstate highway standards,

the expressway is a flagship infrastructure project of

the Government of the Philippines with daily traffic

flow of over 160,000 cars. The world-class toll

road connection is expected to boost the industrial

development of central and northern Luzon, the

largest and most economically significant island in

the Philippines, and spur tourism in the north of the

country. Under a number of design and construct

contracts since 1998 to redevelop the expressway,

we were responsible for upgrading and widening

84 kilometres of expressway in North Luzon and

constructing 110 additional lane kilometres for a

total of 350 lane kilometres. Other works included

improvements to existing interchanges, demolishing

more than 90 existing toll booths and constructing

145 new ones on the expressway and at interchanges,

building two operation centres as well as bridge

widening, traffic management and the relocation of

utilities. The project is undertaken on a rehabilitate-

operate-transfer basis with a 30-year concession period.

Central-Wan Chai Bypass – Central InterchangeHong Kong

The Central Interchange is part of the 4.5-kilometre

long Central-Wan Chai Bypass trunk road connecting

the Rumsey Street flyover in Central to the Island

East Corridor in North Point. The construction of the

underground Central-Wan Chai Bypass will provide

much needed traffic congestion relief in Central, Wan

Chai and Causeway Bay by allowing traffic to bypass

the heavily congested waterfront roads in these

districts.

The works include two bridges totalling 305 metres,

224 metres of cut-and-cover tunnels, a 116-metre long

approach ramp, realigning and reconstructing existing

roads and associated landscaping works. Due to the

project’s complex site logistics and space restrictions,

a Central Community Liaison Centre was opened in

March 2011 to address and manage stakeholder and

public issues regarding this project.

Tunnel

From cost-effective cut-and-cover

construction to precision drilling and

blasting, sophisticated tunnel-boring

machines and more, our tunnelling works

are built on our extensive project planning,

design and management knowledge

and experience. Through our Centre of

Excellence in Hong Kong, clients benefit

from our comprehensive understanding

of tunnel and underground construction,

especially in dense urban environments,

and our experience with in-tunnel works

like track installations, electrical and

mechanical works, cladding, portal

construction and beyond.

23Tunnel

The Eagle’s Nest Tunnel is a critical link of Route

8, which connects Sha Tin in the New Territories to

West Kowloon. With three lanes in each direction, the

twin 2.1-kilometre long tunnels are designed to help

ease traffic congestion on the main roads between

the two districts. Six drill and blast jumbo rigs were

employed to construct all the tunnels, including a

400-metre long adit used for tunnel ventilation. Tunnel

blasting was required to adhere to strict vibration limits

within a 60-metre protection zone around various key

water supplies facilities. The project also included

Eagle’s Nest TunnelHong Kong

the construction of various ventilation housings and

an administration building, site formation and slope

works, a toll plaza with a subway and footbridge

as well as electrical and mechanical systems, such

as tunnel ventilation, fire services, lighting, power

supply, central monitoring and control, air quality

and toll collection. Landscaping was extensive as a

natural stream that originally crossed the site had to

be recreated to flow along both sides of the southern

approach to Butterfly Valley. Boulders from the original

stream were placed along the recreated one.

Chenani-Nashri TunnelIndia

As India’s longest road tunnel, the 9-kilometre long

Chenani-Nashri Tunnel is being built in the lower

Himalayan mountain range to connect Chenani with

Nashri near Udhampur, in the Indian state of Jammu and

Kashmir. The two-lane tunnel will act as an all-weather

alternative to the existing National Highway 1A section,

which passes through steep mountain terrain and is

closed for 40 days each year due to adverse weather

conditions.

The main tunnel will be connected to an escape tunnel

via pedestrian passages ever 300 metres and vehicular

crossings every 1.2 kilometers. The New Austrian

Tunnelling method (NATM) of sequential excavation and

support is being used to construct the tunnel, which is

located at an elevation of 1.2 kilometres.

Our work involves the construction of a 10.9-kilometre

long highway that includes the 2X 9-kilometre long

tunnels, a 50-metre long single-span bridge that

requires 600 metres of embankments and slope cuttings

and a 40-metre long single-span bridge with 2.0

kilometres of surface works. Also included are all civil,

structural, architectural, mechanical, electrical, power

distribution, ventilation, lighting, supervisory control

and data acquisition (SCADA), fire control system,

video surveillance, traffic control, emergency call and

communications works.

Salkhit Wind FarmMongolia

The Salkhit Wind Farm is a landmark project in Mongolia

in terms of the development of clean and renewable

energy sources. When operational, the 50-megawatt

wind farm will cut CO2 emissions by an estimated

200,000 tonnes, reduce coal consumption by some

190,000 tonnes and save 1.9 million tonnes of fresh water

each year while generating nearly 5% of Mongolia’s

current electricity. Mongolia is targeting to generate

25% of its electricity from renewable sources by 2020

under the National Renewable Energy programme.

We are designing and constructing roads, wind turbine

foundations, the electrical substation and the site’s

electrical infrastructure some 70 kilometres southeast

of Ulaanbaatar. Key challenges include transporting the

25-metre tall sections of the towers, turbines, 40-metre

long blades and 50-tonne nacelles from the various

factories in China to the windy and mountainous site,

which is located 700 kilometres from the Mongolian

border. The tower sections will be bolted together

and erected to a height of over 80 metres before

the 1.6-megawatt turbines, nacelles and blades

are installed.

Manjung Power StationMalaysia

Designed to help address rising electricity demand in

Malaysia, the Manjung Power Station was developed

by TNB Janamanjung as one of the largest coal-

fired projects in Southeast Asia and the first to meet

World Bank standards on emissions in Malaysia. The

2,100-megawatt capacity coal-fired power station

was constructed on a man-made island of about

325 hectares, approximately 288 kilometres north of

Kuala Lumpur.

We were subcontracted by the engineering,

procurement and construction contractor, a

consortium formed by ABB Alstom Power Plants and

Peremba Construction, to prepare the site as well

as the power block, combustible, coal effluent and

flue-gas desulfurisation areas, main cooling system,

electrical substation, utilities and networks. For the

cooling water intake, we manufactured and placed

10-metre long three cell precast concrete box culverts

weighing 490 tonnes in a pre-dredged trench. We also

constructed a 200-metre high and 20-metre diameter

chimney with a reinforced wind shield as well as the

infrastructure needed to receive and transfer coal,

including transfer towers and conveyors.

Environment and waste remediation

35Environment and waste remediation

Every day, about 800 tonnes of sludge are produced

by Hong Kong’s 11 sewage treatment plants and

much of it is simply dumped in landfills, which have

a limited life. With the amount of sludge forecast

to rise to some 2,000 tonnes a day in the coming

years, the government is turning to incineration

as a sustainable treatment that is more in line with

Sludge Treatment FacilityHong Kong

international practice. From 2013, Hong Kong will

realise significant environmental benefits as the

world’s biggest sludge treatment facility comes on

stream. The facility is estimated to reduce the volume

of sludge by as much as 90% and cut greenhouse

gas emissions by up to 260,000 tonnes

each year.

The project includes the designing, construction,

testing and commissioning of the state-of-the-art

self-sufficient facility, which can treat 2,000 tonnes

of sludge a day. Inside, the facility is equipped with

incinerator boiler furnaces that produce steam, which

drives turbines capable of generating 14 megawatts

of electricity, more than enough to cover the plant’s

energy needs. Surplus electricity can be exported

to the power grid for external use. There are also

flue gas treatment lines that comply with emission

standards. A seawater desalination plant supplies the

facility with up to 600 cubic metres of desalinated

water per day while wastewater is recycled at the

site to help protect the environment. Outside, the

facility adopts an aesthetically pleasing wave form

architectural design inspired by the sea and hills

surrounding the waterfront site in the western part

of the New Territories. Visitors are transported by

electric bus to the facility’s environmental education

centre, where they can go on guided tours to learn

about the plant installations and the treatment

process. There is also a landscaped garden with

a habitat for water birds.

Harbour Area Treatment Scheme Stage 2AHong Kong

In one of the most important environmental protection

initiatives undertaken in Hong Kong, the government

introduced the Harbour Area Treatment Scheme (HATS) to

collect and treat sewage on both sides of Victoria Harbour.

The HATS Stage 2A Project further improves the city’s

water quality by treating the remaining 25% of sewage

generated on the northern and southwestern sides of

Hong Kong Island. With Stage 2A, the capacity of sewage

collected a day increases from 1.7 million cubic metres

to 2.44 million cubic metres for centralised treatment on

Stonecutters Island under the HATS project.

To develop a sewage conveyance system from Aberdeen

to Sai Ying Pun, we are constructing 7.5 kilometres of

deep sewage tunnels. The use of advanced drill and blast

techniques, which are new to Hong Kong, is resulting in

more precise detonations that significantly reduce blast

vibrations and noise and require less explosives and

concrete backfill. Grouting is efficiently used to prevent

water inflow during the tunnel construction.

We are also erecting noise enclosures that are twice

as effective as common ones in Hong Kong and

are successfully engaging the community through

volunteering and educational activities. The project

was recognised at the 2010 Hong Kong Awards for

Environmental Excellence and the 2010 Considerate

Contractors Site Award Scheme.

Central Reclamation Phase III – Engineering WorksHong Kong

This massive and complex marine and civil infrastructure undertaking

is an integral part of a high-profile project to reclaim almost 18

hectares of land from Hong Kong’s harbour and allow for the

future strategic development of the Central waterfront. The project

involves the dredging of 900,000 cubic metres of material and the

construction of over 1 kilometre of vertical wave-absorbing seawalls,

ferry piers, a railway overrun tunnel, a dual three-lane road tunnel,

a heliport, precast cooling water pumping stations and pipelines as

well as drainage and other works. Reclaiming land from Hong Kong’s

harbour safely, responsibly and efficiently requires adherence to strict

environmental standards and a number of technical innovations.

Sedimentation pits line both sides of the site to prevent polluted water

from entering the harbour just 20 metres away while trucks drive

through wheel washers before entering the city.

A key innovation is the use of precast caissons, weighing as much as

9,500 tonnes, which greatly reduce noise, waste and water pollution.

The precast components are made in China and are delivered to

Hong Kong by semi-submersible barge to be floated into position. We

also employ the much quieter diamond-wire saw for cutting instead of

traditional hydraulic breakers. For the dual three-lane road tunnel, we

place about 450 diaphragm wall panels on either side up to 55 metres

below the sea level. This is one of the largest quantities of diaphragm

wall used in a single project in Hong Kong. More than 3 million cubic

metres of landfill, over 68,000 tonnes of steel reinforcement, over

400,000 cubic metres of concrete and more than 100,000 cubic

metres of precast concrete are being used in the construction works.
