It is the third, and final. phase postwar airport development scheme costing over HK$140,000.- 000, which has included the con- struction of an 8.3-10 foot runway out into the waters of Kowloon Bay. And before the new building was completed it was decided to Zo ahead immediately with an exten- sion to the new terminal by build- ing a new wing at the north-west comer. This extension was includ. ed in the original plans but was ex- cluded for financial reasons. The growth of the demand on the facili ties of the Hong Kong airport has made it essential to reinstate straightaway. Provision has been made for extension to the north- west also but this will not be un- dertaken immediately.

The opening of the giant runway led to great increase in traffic at Kai Tak. In 1951. 5.200 aircraft and 75.000 passengers used the air- port. In 1961 the figures were 14.195 aircraft and 578.300 passen- gers. This huge increase and the likelihood of a still greater increase in the future
made it essential
to plan for weil into the future when designing the new terminal.

The generally accepted standard of 15 square feet per person adopted and the public areas of the new building provide for 550 pas- sengers. 1.650 friends (meeting or saying farewell) and 230 sightseers at peak hour, because it is peal: hour that counts in planning and not the overall daily movement. The restaurant has a seating capacity of 220. The planning of the public areas has also taken into account the fact that Hong Kong has an ab- normally high proportion of friends seeing off or meeting air passengers. The average in Hong Kong is three to each passenger compared with enly one at London Airport.

The whole of the new terminal stands on reclaimed ground and is based on cast-in-situ piles. Conven- tional reinforced concrete construc- tion has been used throughout the whole building. The plan is set out 20-foot grid and spans are uniformly 20 feet or 40 throughout. All roofs are of hollow tiles between reinforced concrete ioists to help in insulation of the building. which, except for certain stores and service rooms, is air- conditioned throughout.

Roof finish is in asphalt over which are placed pre-cast concrete five-legged tiles. The legs raise the 12 inch by 12 inch tiles about two inches above the roof finish to al- low an air space between the roof and the tile.
Considerable attention was given in planning to the sound proofing of the building from aircraft noise. Except in toilets, plant rooms, stores and service areas, double windows have been adopted throughout the building, including the main public areas. Two completely separated rows of windows with
a 12 inch space between them have been used. The outer row is fixed and the inner can be opened for cleaning. One outside window on each up- per floor opens to allow cleaners to reach the walkway. All opening windows close against the frames on a plastic seal.

On both sides of the office block there are five-foot wide projecting canopies from the window heads in slatted concrete to reduce sky glare. These also serve as walkways for cleaning the fixed external windows. Vertical louvres have been avoided here so
that maximum view all round from the offices can be ob- tained. Vertical louvres have how- been used on the north-west side of the ground floor concourse

The outside windows are glazed with 3/8-inch polished plate glass to withstand typhoon wind condi- tions and the inner row with 4-inch glass. The edge of the space be tween windows is lined with acous- tic tile. Doorways opening on to the air side from public areas have sound trap lobbies between two
rows of doors.
Acoustic tile ceilings have been used almost universally throughout the main public areas and the ad ministrative offices.
The Hong Kong climate and the use of fixed windows throughout for soundproofing have made it essen- tial for the whole of the building to be air-conditioned, providing cool. ing in the hot and heating in the cold seasons.
Generally the main structural frame is finished on the outside in Shanghai plaster, which is an equivalent of granolithic, with the addition of coloured aggregates. It

is permanent and does not require painting. Wall panels below win dows of the office block and else where are faced in terracotta tiles,
The stair wall. machine room walls and the control tower below windows have vitreous mosaic tile facing. Mosaic tile is also used on the columns of the upper waving bay.
There is a curtain wall facing the south-west end of the office block in which glass brick solid infill has been used on the V.I.P. block. Brick panels in the north-east elevation and on one side of the apron piers are faced in the traditional Chinese grey brick.
