Example Service Module
741
GENERAL CHARACTERISTICS
The following example of service module design is presented to illustrate
an application of the principles recommended in the Prototype Design. It
demonstrates a hypothetical layout of a functional zone, a subsequent
plan change and the related organization of the services subsystems. The
factors that need to be considered to arrive at the service distribution
patterns are examined in the text and diagrams.
741.1
CONFIGURATION
A hypothetical service module five 22'6" bays in length by two 40'6" spans
in width plus a service bay has been taken as the basis for the example.
The gross floor area of the functional zone is 9,200 square feet, and it is
assumed to have no exterior walls. The service bay has one wall at the
edge of the building. The module is at a support function level on a lower
floor of a nine-story building. It combines with a similar module, adjacent
to its long dimension, to form a fire section of 18,400 square feet bounded
by two-hour fire partitions. Between these two modules is a smokestop
partition from floor slab to floor slab through the functional and service
zones.
In practice, this service module would have been the result of studies of
space modules for the nursing units, studies of typical functional layouts
within the rest of the hospital program and the total hospital configuration
that was selected for a particular project.

THE SHELL
Figure 740-1 illustrates the physical framework of the service module. It
includes the structural members, the ceiling components and the
mechanical rooms of the service bay, all of which are permanent
components of the module. The configuration of these permanent
components is a major constraint on the service distribution design.
The following selections were made for these components from the
generic design options:
1. The structure is based on reinforced concrete construction, eighteen
feet floor to floor with a ten-foot functional zone.
