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. VIEW OF CHANGI AIRPORT SHOWING CONTROL TOWER AND PARKING PANAROMIC VIEW OF CHANGI AIRPORT-TERMINAL 1 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.

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. DETAIL LEVEL PLAN OF TERMINAL 1 ROOF TOP SWIMMING POOL LILY PAD GARDEN Featuring circular roof shelters with strategicallyplaced electric fans, this is possibly the breeziest garden in the airport. Each ‘Lily Pad’ structure is actually a water catchment, channeling rainwater for reuse. FIGURE SHOWING LLILY PAD GARDEN FIGURE SHOWING ROOF TOP SWIMMING POOL CACTUS GARDEN The Cactus Garden features more than 100 species of Cactus and arid plants from the deserts and dry areas of Asia, Africa and America. This roof garden also serves as a smoking area and is a popular place to sip a drink at the bar while basking in the sun.

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. STRUCTURAL PROPERTIES OF TERMINAL 3 CAST-IN-SITU BORED PILES 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. 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.

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 MAIN ROOF TRUSS AT T3 WARREN SPACE TRUSSES VERTICAL SECTION 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. 3D OF THE ROOF DEATILING Soft natural lighting lower the temperature and save energy consumption of the terminal NATURAL LIGHT THROUGH LOVERS Columns are treated with timber clad to enhance the tropical ambiance. DETAIL OF BUTTERFLY LOUVERS SKETCH OF BUTTERFLY LOUVERS 6/12 WATER FEATURES 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 . • 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. Concept of the Facade • Glass structure demonstrate the concept of openness and transparency. CABLE NET DETAILS WATERFALL DETAILS VIEW OF SPIDER CLAMPS 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 GREENWALL AT T3 WITH ROOF AND LIGHTING SECTION THROUGH GREENWALL VIEW OF GREEN WALL WITH COVE LIGHTING 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. 7/12 INFRASTRUCTURE AND CONSTRUCTION OF CHANGI AIRPORT CHANGI AIRPORT CONTROL TOWER • The Air traffic control tower (ATC) was constructed as part of Phase One of the Changi Airport redevelopment plan. The iconic tower is situated between Changi International Airport 2 runways and stands at about 81 m Above Mean Sea Level (AMSL). It provides aerodrome control service to aircraft landing and departing Changi Airport and aircraft maneuvering within the airport. RUNWAYS • Changi Airport has two parallel runways, 02L/20R and 02C/20C, each 4,000 by 60 m (13,123 by 197 ft). AIRPORT HOTEL The Crowne Plaza Hotel is linked to Changi Airport's Terminal 3 via a covered link bridge, with Terminals 1 and 2 reachable by Skytrain which located within the immediate vicinity of Changi Airport. lt is 9-storey high and has 320 guest rooms. PASSENGER TERMINALS • Changi Airport currently has three terminals, T1, T2, and T3, with a total annual handling capacity of 66 million. Airfield Infrastructure • Changi’s runways, taxiways and airfield objects are designed with adequate safety separation to meet A380 requirements. • Runway Length and Width -Changi’s 4km long by 60m wide runways exceed A380 take-off and landing requirements.

This terminal will replace the previous Budget Terminal. Cathay Pacific will be the first airline to operate from the terminal, followed by Korean Air, Vietnam Airlines, and the AirAsia Group (AirAsia, Indonesia AirAsia and Thai AirAsia). Terminal 5 • • • • • • A fifth terminal, Terminal 5,was ready by Transport Minister, Lui Tuck Yew on 7 May 2013. Terminal 5 is built on 1,080 hectares of reclaimed land in Changi East, making it one of the largest terminals in the world. The terminal could handle a capacity of 50 million passengers annually. With the addition of the fifth terminal, Changi Airport is be able to cater to more than 135 million passengers every year. With the national carrier at Terminal 5, each alliance of airlines such as Sky Team and One world could also operate out of dedicated terminals. Terminal 5 has more self-service facilities and bigger lounges. Terminal 5 will be linked to the other terminals at Changi Airport. This will allow the expanded Changi Airport to be operated as a single, integrated airport for ease of transfer between different terminals, maximum passenger convenience and airfield operational efficiency.
