Analysis of Building Systems and Modules--
Service Module
Typical Size/Dimensions
27'-0" x 27'-0"
Structural Bay
external, near corner of module.
Location of Service Bay
do not extend through interstitial service zone.
Fire Sections
Service Bay
Layout in Plan
Rectangular, typically located near corner of module.
Layout in Section
Extends from structural floor to structural floor.
Service Zone
19'-4" typical floor to floor (20'-4" clinical floors); 9'-3 " typical from
Subzones
top S-1 to bottom S-6 platform; S-7 12 " w/ 9 ft ceiling and 19'-4"
story height.
Services require header in S-3 subzone to reach far end of module,
S-3 Channels
mains then take off perpendicular to header and extend through S-3
sub-zone at intervals. Typical 5 channels parallel to purlins for deck
(4 purlins at 6'-5" spacing per 27 ft bay).
typical 6 channels per 27 ft bay; hanger spacing varies.
S-4 Channels
Operation
Plan configuration locates most service bays near courtyard at a corner of the service module.
Main service runs are routed around the edge of the courtyard, requiring S-3 channels to make
90-degree turns. Service distribution patterns allow for continuous access aisle only around the
perimeter of the entire floor. No cross aisles are provided between service modules. This con-
dition increases the difficulty of access and increases the potential or "cross service" between
modules.
Maintenance/Repair
Access is fair compared to other Medical Centers due to lack of circulation aisles in transverse
direction. Lighting level is good. Receptacles are available for tools. No drains in service
zone(interstitial).
Modifications/New Construction
Remodel work was in progress on 9th floor during survey. Work was proceeding without disrup-
tions to occupied space on floor below.
