Planning Module Applications: Design Configurations
251.3.4
In the general case, the service module has no external exposure
requirement, and can be assembled in a very direct pattern. Using
rectangular modules, three sides of the module are available for
attachment or access and the modules can be combined, incrementally, in
two directions.
Figure 250-7 illustrates this general assembly pattern. This diagram also
points out the general configurations which have service strips. A dotted
line on the diagram gives an indication of the types of configurations in
which an expansion joint becomes necessary.
The assembly of service modules in the support areas is very much a
process of adjusting the service module shape and boundaries to the
programmatic requirements of the hospital. Detailed resolution of the
service module configuration is an integral part of the design process,
therefore specific statements about the assembly characteristics are not
relevant in all cases. (See Section 735.1.2 for discussion of service
modules in the Building Schematic Design.)

ASSEMBLY CHARACTERISTICS OF THE FIRE SECTION
Configuration studies are generally initiated through the assembly of
space modules or service modules, but the service module and fire
section are so interrelated that the fire section becomes a significant
consideration. (See Section 240: Fire Sections)
The basic assembly characteristics of the fire section are:
1. Its area must not exceed the 20,000 sq. ft. limit set by current fire
safety practice, and,
2. It follows a simple geometry which is derived from the service module;
the boundaries of the fire section are coincident with the boundary of
the service modules contained within it.

SUMMARY OF CONSTRAINTS
A summary of principal assembly characteristics is presented in Figure
250-8. These are keyed to the simple and compound assembly patterns
and emphasize the special characteristics which may occur in a
compound configuration. The figure also provides a general checklist of
characteristics for any additional design configuration studies.
