Example Service Module: Opening Configuration
Nevertheless, acceptance of the simple rule demonstrated here will
greatly ease location and installation in the majority of cases. Special
cases can be pointed out in the contract documents and provision made
accordingly.

PLUMBING DISTRIBUTION
Figure 740-6 shows the layout of the main and branch distribution of the
plumbing subsystem. The plumbing for this functional zone is relatively
simple but shows the general principles. The drainage is collected at
separate mains on each side of the central girder. (The drainage mains
actually serve the floor above, which for this example is assumed to have
drains in the identical location as the radiology suite.)
All the branches are in the S2 subzone between the beams. As discussed
in the following section, electrical work is heavy in the radiology suite
areas and some large branches are required for this service. In this
example, it was found quite possible to use hanger spaces other than
those occupied by the large electrical runs, thus avoiding a conflict
between plumbing drops and the large wireways below. This is a
consideration which is likely to occur between the two services in most
areas of the hospital.
As discussed under HVC distribution, the layout is shown
diagrammatically. Plumbing layouts are not shown to this degree of
specificity traditionally, but to achieve the coordination required by the
Prototype Design, such layouts are essential. The simplicity of general
predetermined routing makes the diagrams feasible and effective working
documents.

ELECTRICAL DISTRIBUTION
Figure 740-7 shows the layout of the electrical mains and branch
distribution. Communications, which has not been considered in this
project as an integrated subsystem, has been shown to illustrate its layout
in relationship to the electrical power and lighting runs.
Two electrical systems are carried in the main wireways in this service
zone, normal and emergency. In general, each bay has one pair of 2-1/2"
square wireways carrying normal distribution of 208/120 volts and 480/277
volts. Wireways carrying emergency distribution are provided in separate
hanger spacings as required; in this example for corridor lighting, one
radiology room and the radiology viewing room.
