Partitions: Dimensions

DIMENSIONS
333.1
HEIGHT
All components of the partition subsystem (except two-hour fire rated
partitions) will stop at the ceiling-platform, which will have a uniform height
throughout each fire section and preferably throughout each floor.
Nursing areas have a nominal floor-to-ceiling height of nine feet. The
support areas have a nominal floor-to-ceiling height of ten feet. The exact
height of the partitions is a function of the particular detail selected for the
partition/ceiling interface. (See Section 322.2.)
333.2
THICKNESS
Thickness of partitions may vary as required for loading, fire safety, and
acoustic criteria. On the basis of loading criteria and typical construction,
the recommended minimum width of metal studs (Option 1) is 3-5/8",
whereas the minimum thickness of laminated gypsum partitions is 2-1/4".
(See Section 334.3.) Relocatability of door frames is facilitated if all
partitions are the same thickness.
333.3
DOOR SIZES
Door frames extend from floor to ceiling, surrounding standard height
doors with transom panels over. The nominal width of door openings will
vary between two and eight feet. The maximum size single leaf permitted
is dependent on the weight of the particular door because the lateral load
introduced by doors, and impact from door slamming, must be
accommodated by the ceiling subsystem.
333.4
CONSTRAINTS ON PARTITION LOCATION
No specific partition module or planning grid is required. In many areas of
the hospital, a modular partition system with exposed joints will be
unacceptable because of aseptic requirements. However, partitions
should be located so that plumbing drains do not coincide with structural
beams or perimeter girders. Also, the drops for services associated with
partitions should not conflict with the structural members of the ceiling-
platform. An implied dimensional discipline for partition layouts results
from these considerations.
