ABSTRACT
The building design team needs information on the size and location of services plant spaces and their interconnecting ducts before the engineer has sufficient data on which to base calculations. Theremay be only general definitions of the spaces to be heated or air conditioned and preliminary design drawings. Past experience of similar constructions reveals the likely plant and service duct requirements. The use of such data is explained and worked examples are used. The planning of external utility supplies is shown, together with typical arrangements for internal multi-service ducts. Support and expansion provision for distribution services is demonstrated, as is the design of combustion air ventilation for boilers.
