8-m grid which co-ordinates the sche- duled room sizes and structure of all the buildings in the central area. The construction is based on a simple structural bay of 8 m by 4 m (except in very large areas such as the hydrau lics and structures laboratories).

The structural system reinforced concrete frame takes account of the need to provide for alterations to the layout of partitions, services and la- boratory furniture as simply as possi- ble but without undue initial cost. The main runs of laboratory services will be routed along corridors below the upper floor, and branches from there will penetrate the floor to the rooms above and the ceilings to the room below.
Floor and ceiling planes are design- ed to be continuous, and the ceilings will be unperforated and strong enough to restrain partitions. All parti- tions other than fire-walls will be fixed between floor and ceiling. The con- tinuous and unperforated ceilings will reduce the transmission of sound from one room to another; partition walls will have absorbent material applied to them to attain the necessary reverbera- tion standards.
The internal block partition sys- tem, constructed from floor to soffit of the continuous ceiling, will give ade- quate sound insulation between rooms. To diminish sound transmis- sion between corridors and rooms
through the extract system, attenuated grilles will be used; these will be de- signed to insulate to the same degree as a closed door. Absorbent materials to control reverberation within rooms will be used, as necessary, on wall sur- faces.
The roof is designed to have a U-value of 0.85 W/m2 degree C, and the external walls one of 1.7 W/m2 degree C. External walls will be pro- tected from the sun between 08.00 hours and 18.00 hours by verandahs or louver baffles or a combination of both; these forms of sun protection will be designed to achieve an even dis- tribution of daylight while counter acting both sky-glare and excessive brightness contrasts. Tinted anti-glare glass will be used in the windows.
Administration building
The administration building will be the first Institute building accessible to the arriving visitor and will be located in a strategic position where academic, social and residential areas meet. It will be linked, by a covered way, to the civil engineering building and, at a later stage, there will also be covered links with a library and with a special complex to be known as the AIT Centre for short-term visitors at- tending special Institute and diploma courses. (Both the library and the AIT Centre will be added at a later stage of the first phase of development.)

Like the civil engineering building, the administrative building is based on an 8-m grid. The general accommoda- tion is planned in a square single- storey block designed around an in- ternal courtyard; an upper floor has been added along one side, housing the boardroom and offices for the presi-. dent and senior staff. Standards of thermal insulation and sound absorp- tion are as for the civil engineering buildings.
Campus services' complex
The campus services' complex in- cludes a main building, housing work- shops, stores and warehouses; an ad- jacent building containing administra- tive offices connected with the ser- vices, a vehicle maintenance shop and servicing ramp; a hardstanding area for vehicles (later to be replaced by a garage); a water tower; and a building to house the central chiller plant, the central sewage pumps and one of four electrical sub-stations. All the build- ings, except the office block, will be of a semi-industrial nature; the roofs will have good overhangs to protect ex- ternal walls from the sun.
Residential accommodation
The student dormitory complex will consist of eight three-storey blocks containing 352 study-bed- rooms. There will be a dining-room capable of taking 180 people at a sit-
