Hong Kong International Airport (HKG/VHHH), Chek Lap Kok, Hong Kong

The construction of Hong Kong International Airport at Chek Lap Kok was one of the biggest operations in the industry. The core programme cost more than $20bn and involved four major sponsors, ten separate projects, 225 construction contracts and over 1,000 critical interfaces.

The airport covers 12.48km² of reclaimed land between the two islands of Chek Lap Kok and Lam Chau. The airport increased the land area of Hong Kong by 1%. The airport opened for business in July 1998 having taken just six years to build.

There are two parallel runways (3,800m x 60m); one is category II and the other is the higher category IIIA allowing landing in only 200m visibility. A third runway has been considered but this is still very much in the planning stage.

In January 2008 to increase operational efficiency the airport introduced RFID (radio frequency identification) baggage tags to the airport check-in procedure.

The new tags printed out to tag passenger luggage contain an embedded RFID chip along with a barcode. The tags can be read from a distance and with an efficiency of around 97% compared to 80% for barcode-only tags and are now being issued in terminals one and two and in Kowloon Station to about 40,000 bags a day for 50 airlines. RFID luggage handling has already been approved by the IATA (International Air Transport Association).

HONG KONG AIRPORT FACILITIES

Hong Kong International Airport is the fifth busiest in the world; it sees an average of 650 aircraft take-offs and landings every day and carried over 44.5 million passengers in 2006. The cargo areas are some of the world's busiest and handled over 3.6 million tons in 2006.

The shopping and leisure facilities include the airport's SkyMart with 160 shopping outlets and 40 restaurants spread over 39,000m². The facilities also include free and pay internet lounges, Wi-Fi access, many lounges and TV screens and a children's play area. The superior facilities have meant that the airport has been voted the world's best in 2002, 2003, 2004 and 2005 (came first in Skytrax's world airport awards in 2007) and is consistently in the top-five list.

AIRPORT ACCESS

A new transportation corridor stretches 34km from Hong Kong Island to the site of the airport, incorporating a high-speed rail system, two tunnels, two bridges and a six-lane expressway.

Designed for the rapid movement of millions of passengers, the airport has 288 check-in counters, 200 immigration desks and 80 customs positions. The new airport also boasts 2.5km of moving walkways and around 120 shops.

Negotiations between the Chinese government, the Chek Lap Kok government and (until the handover of the colony in 1997) the British government were complex. However, the main difficulties were resolved by the mid-1990s.

FUTURE DEVELOPMENTS

The future development of the airport is looking vibrant with the construction of a new development adjacent to the passenger terminal called Sky City. This consists of Sky Plaza – an office, retail and business complex integrated with the passenger terminal (terminal two), which then links to the rest of Sky City.

Sky City has the Asia-World Expo exhibition centre, a second hotel project (Marriot Hotel Sky City opening in December 2008), a nine-hole golf course and a permanent cross-boundary ferry terminal (Sky Pier). Phase two may well consist of a business park, more hotels, and further leisure and entertainment facilities.

The Sky City complex is expected to gain much business from the opening of the Disney theme park (opened in September 2006) as will the airport itself. The architect, planner and engineers for the Sky City project are Skidmore, Owings and Merrill.

The Sky Plaza was opened in February 2007 and included the second terminal of the airport and a new airport express platform, which serves the new terminal (Sky Plaza and terminal two have a floor area of 140,000m²). The shopping mall opened as well providing a variety of shops, restaurants and entertainments for passengers.

The project also involved the expansion of the east hall of terminal one to provide integration with the overall airport complex (terminal one is now 570,000m²).

The airport has also added extra inter-modal transportation facilities, including the new marine terminal (hosting the cross boundary and domestic ferries), an additional airport express line (new platform opened for T2), which will be adjacent to the exhibition centre and a new coach station (this was opened in terminal two in February 2007).

Sky Plaza, which extends from the passenger terminal and is fully integrated with the airport and airport express railway station features airline check in facilities, a transport interchange for coaches (in readiness for Disney), two office towers (total of 30,000m²) and a 38,000m² retail and entertainment centre. Sky Plaza (T2) is only used for departures of passengers.

Sky Plaza cost an estimated HK$2bn to complete. The contract for the construction was awarded to Chun Wo-Fujita joint venture. A new land transport terminal is situated in Sky Plaza providing improved services for cross boundary coach passengers (36 bay coach station allowing 240 trips a day across the border). This includes customs, immigration, quarantine and security screening facilities.

A three station people mover system connects Sky Plaza to the existing passenger terminal (a contract for this was awarded to Ishikawajima-Harima Heavy Industries). The driverless APM (automated people mover) system runs at 62km/h and there is a train every 1.5 minutes to provide transport from check-in to the gate areas.

A contract for extending the people mover tunnel to allow for a future direct connection between Sky Plaza and the airport's ferry terminal was also awarded to the Chun Wo–Fujita joint venture.

CARGO EXPANSIONS

DHL opened a new Central Asia Hub in August 2004, a dedicated and purpose-built air express cargo facility, at the Hong Kong International Airport. The $100m facility is the largest of its kind in the region. With the opening of the new Central Asia Hub, DHL became the only express and logistics company to operate a dedicated air express cargo facility in Hong Kong. The 18,200ft² facility is capable of handling up to 440t a day of air express cargo.

Another important cargo development was the expansion of the Asia Airfreight Terminal, which was announced in 2004. Asia Airfreight invested HK$1.75bn in the construction of a new terminal (completed by the end of 2006). The terminal has a handling capacity of 910,000t a year, which triples its current capacity.

Air cargo growth in Hong Kong has been growing at 6% a year and express cargo at 13% a year. The new facility means that Asia Airfreight can meet long-term cargo capacity demands.

In March 2008 the board of the Airport Authority of Hong Kong awarded a 20-year franchise to design, construct and operate a new 246,000m² cargo terminal at the airport to Cathay Pacific Services Limited. The new terminal will begin construction in 2008 and is scheduled to open in the second half of 2011.

The facility will have an annual capacity of around 2.6 million tons and will increase the airport's total general cargo handling capacity to 7.4 million tons per annum. The new facility is being constructed on a 10ha site in the cargo terminal area and when open will employ 1,700 personnel. The number of general and express cargo operators at HKIA will then increase from three to four. Cathay Pacific's investment in the new facility will be of the order of HK$4.8bn.

The cargo terminal will provide an exceptionally high land use efficiency of over 25t/m² and will be equipped with a state-of-the-art materials handling system (MHS) to handle the massive throughput.
