The Service Module: Size and Shape
Where courtyards are formed within a single span, the length of the
courtyard can vary in increments of the particular beam spacing.
In some configurations, service modules other than rectangles may be
appropriate. (See Section 251: Design Configurations.) Service modules
can be `L', `T', or `U' shapes provided that the constraints imposed by the
structural bay and service distribution are respected.
These service modules may be regarded as single span service modules
with a limited number of additional bays attached laterally. Main
distribution of the mechanical, electrical and plumbing subsystems is
confined to the single span service module and the additional bays are
served by branch distribution.
