5. Radio Auditorium, connected to Radio House by an entrance hall: a 1,000 seat auditorium for broad- casting concerts and dramas with a live audience.
6. Engineering Building, incor- porating facilities for the planning, research and development of all broadcasting techniques.
The first buildings are now com- plete and occupied. Work on the bored pile foundations for Radio House began in March 1967 and this stage is due for completion in 1970.
Integrated Services Building
The 10-storey Integrated Services (Admin.) Building is perched on the extreme northern edge of the plateau overlooking the Federal Highway. It cost approximately M$5 million and contains seven identical floors of office space, each floor providing 11,000 sq. ft. gross area and 8,000 sq. ft. net office space.
Other accommodation includes: Lounge, dining room and observation deck on the eighth floor; kitchen and main dining room on the ground floor, designed to cater to two sittings of 375 diners at the mid-day meal; and a lower ground floor (below ground on the south side but above ground on the north side) containing a parking garage for 21 vehicles, electrical sub-station, air-conditioning fan room and service entrances for the building and the kitchen.
Fifteen per cent of the office space, or 11⁄2 floors, are occupied by the Ministry of Information and Broadcasting, 35 per cent (21⁄2 floors) for television administrative and pro- gramming personnel, and 45 per cent (3 floors) for radio and other in- tegrated services.
The building may be expanded by adding two 22ft. 6in, bays to the west end a further 16,000 sq. ft. of office space.

As the administrative heart of the complex, the building contains the greatest concentration of people. It has been sited to allow the shortest possible approaches by foot up the north face of the site from bus stops on the Federal Highway and from a parking lot centred in the site while at the same time affording the greatest number of people with a view of the city.
Its east-west orientation permits the most economic means of controlling the heat load from direct sun. The narrow east and west ends of the building receive the greatest heat load and therefore have less glazed area.
All sides are shaded from the sun by a sunscreen comprising 630 precast terrazzo concrete shields. Each shield

Behind the sunscreen is a continu- ous window wall glazed with tinted glass above the window sill and with insulated infill panels below.
The seven floors of offices have been designed to provide maximum flexibility for sub-division into standard Government sizes of private, semi-private and general offices. The air-conditioning, lighting and ceiling have been co-ordinated so that de- mountable partitions may be erected in any of a number of predetermined locations as required to provide all standard sizes of offices.
An entire floor may be left un- partitioned or it may be intensely partitioned with equal economic usage of space while the same level of lighting and air-conditioning is maintained.
The building contains two service cores with the main stairs, three lifts. an electrical room and lavatories in the primary core; secondary stairs, one service lift and another electrical room comprise the secondary core. The area of services, circulation space and lavatories totals 29,600 sq. ft. and the remaining area of 101,800 sq. ft. is usable floor space.
On the 8th floor (275 ft. O.D.) is a large lounge, a dining room (served from the main kitchen on the ground floor by heated trollies brought up in the service lift) covering about one- half of the roof area, the remainder being outdoor observation deck.
The ground floor (172 ft. O.D.) contains the main kitchen and the staff dining room which has been designed as a multi-purpose room. serving as a meeting place for receiv- ing large groups of visitors, and for various staff and social functions.
The lower ground floor (163 ft. O.D.) is exposed on the north side and joined to Television House by an underground corridor passing beneath the entrance hall. This area contains parking space for 22 vehicles, an electrical sub-station, lavatories for kitchen staff, the main service en- trance for all buildings and a second- ary service entrance for the kitchen.
Three passenger lifts (2500 lb. capacity, 350 f.p.m. variable voltage machines) and one service lift (2500 lb. capacity, 200 f.p.m., 2 speed A.C. machine) provide vertical transporta- tion supplementary to the two sets of stairs.
Structurally, the building comprises a reinforced concrete superstructure supported on two rows of columns spaced 35 ft. apart transversely and at 22ft. 6in. centres longitudinally, the floor slab being cantilevered 12 ft. 6 in, on all sides. The building rests on a foundation of interconnecting, inverted tee-shaped, spread footings at the 155 ft. O.D. level.
The entrance hall, recognizable by its barrel-vaulted roof, is the connect- ing link between the Integrated Ser- vices (Admin.) Building and Televi sion House, and is the main entrance for both buildings. It serves as the
