abattoir is about 1,350 pigs, but by using two dressing lines this figure can be doubled at Chinese festivals. Pro- vision is also made for expanding the throughput of cattle, at present some 170 per day, and sheep and goats, 40 a day Kennedy Town.

At both sites the mortuary and in- cinerator is kept as a separate block. At Kennedy Town the boilerhouse is also a separate block. All the buildings are carried on piled foundations, with ground floor slabs designed as sus- pended floor slabs supported on rein- forced concrete ground beams. Lairage

The Kennedy Town lairage is a five- storey reinforced concrete structure of flat slab design with the columns on a 24 ft. x 27 ft. grid, the column spacing being governed by the desire to reduce the number of columns oc- curring within the areas of animal accommodation and relating the spac- ing to the unit width occupied by the cattle stalls. Flat slab construction was used as the resulting relatively flat and unobstructed ceiling assists in the penetration of natural light and makes ventilation simpler and more efficient.

The external walls of the building are on the edges of reinforced concrete slabs cantilevered out on all sides from the main column grid. The edges of these cantilevered slabs are linked by light concrete posts which, com- bined with the slabs, protect the animals from direct sun.

storey are left open but on the ground floor these open areas are filled with perforated concrete blocks for security reasons and this infilling is incorporated into the walls overlooking the harbour on all floors to give some protection during typhoon conditions.

Double ramps in the centre of the building lead to the other floors and are designed to allow free passage for the cattle, pigs and drovers. Adjacent to these ramps are four vertical rein- forced concrete ducts which terminate at roof level in fan chambers. One 5 ft. diameter fan is installed in each fan chamber to draw warm foul air up from each storey. Extraction from each storey takes place at ceiling level, the foul air being replaced by air drawn in through the open walls.

At roof level adjacent pairs of fans discharge air into enclosed wells in such a way that the air and fan noise is directed upwards and does not in- convenience the occupants of adjacent buildings. An acoustic baffle is pro- vided between the ducts and the fans to prevent the noise being transmitted downwards into the lairage.

All the floors are drained through gulleys provided with baskets for in- tercepting solid matter. The drains are carried to ground level in a number of vertical stacks and discharge into screening and settling pits designed to intercept grassy or solid matter before the effluent passes into the main site drainage system.

The upper floors are waterproofed The upper parts of the walls of each by asphalt membranes. Above the
