3. INTRODUCTION
• Singapore Changi Airport is a major aviation hub in Asia.
• It is located in Changi, about 20km east-north-east of Singapore centre.
• The airport is operated by the Changi Airport Group (CAG) of the Civil Aviation
Authority of Singapore (CAAS).
• The Singaporean Government made a decision to build Changi in 1975 following
congestion at the other airports in Singapore.
• Changi Airport has three passenger terminals with a total annual handling capacity of
66 million passengers. Terminal 1 opened in 1981, followed by Terminal 2 in 1990 and
Terminal 3 in 2008.
LOCATION
• Changi Airport, is the primary civilian airport in the Republic of Singapore, and one of the
largest transportation hubs in Southeast Asia and the greater India region.
• The airport is located approximately 17.2 kilometres (10.7 mi) northeast from the
commercial centre in Changi, on a 13-square-kilometre (5.0 sq mi) site.
• By the 1970s Concerned that the existing airport was located in an area with potential
for urban growth, which would physically hem it in on all sides, the government
subsequently decided in 1975 to build a new airport at the eastern tip of the main island
at Changi, at the existing site of Changi Air Base, where the new airport would be easily
expandable through land reclamation.

Singapore Changi Airport's oldest terminal
operated as the sole terminal from its
opening on 1 July 1981 right up until the
opening of Terminal 2 nine years later.
Configured in a H-shaped layout to
maximise the number of aerobridges which
may be built, it underwent two major
upgrading works over its lifespan.Handling
capacity-21 million passengers.
Today, the terminal spans an area of
308,000]m² and can accommodate a
maximum passenger capacity of 21 million
passengers a year.

6. STRUCTURAL PROPERTIES OF TERMINAL 3
BASEMENT
• There are three levels of basement in T3 B1, B2, B3 of
which B2 and B3 are in contact with earth.
• For these floors a reinforced concrete flat slab system was
adopted.
• The slab thickness varies from 600mm to 900mm,
depending upon the depth of the basement and span of
the slab. With 500mm drop panes at the pile locations.
• Basement walls up to B2 – simple cantilever walls
(thickness at base- up to 1m).
• For higher walls up to B3 – counterfort or buttress walls
with thickness up to 1m at base, and 800mm thick
brackets spaced at 6m.

BUTRRESS
RETAINING WALL
• A portion of t3 sits directly on top of MRT tunnels serving
the airport. The building loads in this area are supported
on a matrix of large transfer beams at B2 level, to transfer
the load on to barettes or bored piles standing between
the tunnels. The transfer beams form part of the
basement floor in this area.
• Waterproofing : waterproofing admixture that crystallises
on contact with water to form an impermeable
waterproofing barrier within the concrete.
VIEW OF T3 BASEMENT
FOUNDATION
• T3 sits on good soil conditions.
• The soil profile consists of 6-7m backfill underlaid with Old Alluvium, which consists mainly
of clayey, silty sand whose density increases with depth.
• With such soil conditions and column loads varying from 150 tonnes to 3000 tonnes ,
cast-in-situ bored piles were adopted as the most suitable and effective foundation
system.
• More than 4000 piles of sizes varying from 500mm to 1500mm in diameter were installed.
• Tension piles were introduced between columns where uplift forces due to ground water
pressure were substantial.
CAST-IN-SITU BORED PILES
SUPERSTRUCTURE
• Framed structure
• Lateral stability is achieved by diaphragm action of the floors transmitting horizontal loads to the shear walls at various
staircases and lift cores.
• Column grid- 15mx 15m at the main building
12m x 12m at the piers
9m x 8.2m at the car parks
• Columns, floors and walls are cast-in-situ
• Beams- post-tensioned banded beams of width varying from 2m -4m and depth varying from 800mm to 1000mm ,
spanning continuously between columns and supporting precast single T or double T slabs.
• Slabs – composite slab with 75mm concrete topping, and spanning15m between the banded beams.
• Depth – 400mm – 800mm depending on the length of spans and loading.

7. STRUCTURAL PROPERTIES OF TERMINAL 3MAIN ROOF/ FEATURE ROOF
• frontage of 300m length and 215m depth , spanning from airside to landside.
• The main steel structure- series of steel trusses alternating between depths of 4.1m and 4.5m.
• Each of these trusses is 215m long and was designed as a continuous truss, starting with a 20m
cantilever at the departure kerbside and , traversing the main departure hall with internal spans of
20m, 45, and 60m ending with a 10m cantilever at the airside apron.
• These trusses are supported by 850mm dia. And 12m high RCC columns.
• Main trusses- connected by a series of warren space trusses, 15m in length ( forming a secondary
truss frame).
• Roof slab – 155mm thick lightweight concrete slab with shear studs.
• The structural steel members are built up steel sections, except for diagonal Macalloy tension rods.

MACALLOY TENSION RODS
ROOF DETAILS
• A flat but intriguing roof consisting of many skylights
allowing natural light into the terminal building.
• The roof limits the amount of direct sunlight into the
building through the use of louvers suspended above
and below the skylights, filling Terminal 3 with diffused,
ambient light during the day.
• Butterfly shaped reflectors :are computer controlled
to allow optimum amount of diffused sunlight to
stream down through 919 skylights so as to make us of
natural light instead of using electrical lights.
Soft natural lighting lower the temperature and save
energy consumption of the terminal
Columns are treated with timber clad to enhance the tropical ambiance.

8. Concept of the Facade
• Glass structure demonstrate the concept of openness and transparency.
FACADE
• The frontispiece of T3 is the departure hall has a cable net façade.
• it consists of a simple orthogonal grid of cables tensioned vertically
between the roof and the ground slabs as well as laterally between the
roof support columns with glass panels clipped to custom designed cast
cable clamps.
• The cable net is a high deflection system, that depends on this deflection
to develop resistance against an applied wind force. The net will deflect up
to 30cm in maximum conditions. Such extreme values were simulated at full
scale on a prototype 15m wide x 18m high of a typical bay of the façade .
CABLE NET DETAILS
GREENWALL
• Concept : city in a garden
• the green facade is 4,144 m2 and consists of more than 10,000 plants
and 25 species of climbers.
• The plants are grown on stainless steel cables and each cable is
removable in case there is a need to replace plants individually.
• "The green tapestry is 14 meters high and 300 meters long.
• "Strategically located in the mid-belly of the terminal, the wall
separates two main functions, providing a clear demarcation of an
international border; the green tapestry gives it a form that is friendly,
organic, and alive.
• The length is separated only by four water features.
• The Greenwall also helps to regulate the internal temperature of the
terminal with the occasional misting.

COSTRCUTION DETAILS
TAPESTRY STRUCTURE
• The planting system is a double-layer cable support system sandwiching
fiberglass planting troughs.
• Stainless steel beams cantilevered from the wall support horizontal I-beam
modules with 2 feet wide fiberglass troughs, five segments high.
WATER FEATURES
• Four water features 60 feet tall and 20 feet wide made from
shredded glass panels laminated to stainless steel plates, were
added to compliment the wall of green.
• Their shimmering water movement provides texture to create
a rhythm of moving light and sparkle against the elegant
silence of the green tapestry.
