Site

The new operating theatre block was erected on a limited area in the rear court yard of the existing main hospital building, It is the only site adjacent to the hospital which could be developed without seriously affect- ing the existing amenities.

The site subsoil was rocky in na- ture and in order to minimise the considerable noise arising from the removal of rock, the bottom of col- umn footings was raised to the high- est possible level.

Building

The height of the new block is kept to a level not higher than the existing hospital block in order not to affect to a great extent the light and air to the wards in the adjacent wings. The shape of the block is governed by the requirement of the operating theatre suites and each suite, forming a "cul- de-sac department. is so planned to have easy access to the wards it

serves.

The operating theatre suite is divided into steriled zone, clean zone. and dirty corridor so that the chances of cross infection are minimised.

The radiodiagnosis block was erected in the court yard in front of the hospital, supported on columns over the parking area and connected to the existing main hospital build- ing at first floor level. The five ma- jor X-Ray rooms are grouped as satel- lites around the central dark room and viewing room where both manual and automatic processing units are provided.

Services and Equipment Air-conditioning installation
