STRUCTURAL BAYS
The column and beam framing system of the Prototype Design includes
five structural bay sizes, all of which are 22'6" wide. The lengths range
from 40'6" to 58'6", in 4'6" increments. In addition, the length of the bays
may be extended by 18'0" cantilevers.
These bay sizes were developed in conjunction with the planning
requirements of nursing areas and were then tested for their applicability
to the design of the support areas of the hospital. (See Section 710.)
The Prototype Design also includes one other type of structural bay, called
the service bay. (See Section 220.) The service bay does not have
predetermined configuration or dimensions.
313.2
FLOOR-TO-FLOOR HEIGHT
The nominal floor-to-floor height varies between approximately seventeen
and eighteen feet. It includes a recommended floor-to-ceiling height of
nine feet in the nursing areas, or ten feet in the support areas, plus an
allowance for a service zone above the ceiling.
The service zone is approximately eight feet high overall, and extends
from the finished ceiling to the finished floor above. The exact height of
the service zone is a function of the specific design selected for the
ceiling, the structure and the services distribution.
