Analysis of Building Systems and Modules--
Service Module
Typical Size/Dimensions: In plan, the building is basically a large square with two projecting
rectangular wings. Most service modules are rectangular and vary considerably in size depend-
ing on type of functional space. Modules at building corners extend in two directions from the
22'-6" x 22'-6" typical
Structural Bay

Service Bay
Layout in Plan:
Service bays are nearly square in plan.
Service Zone
18'-8" floor to floor; 8'-7 " typical from top S-1 to bottom S-6 platform;
Subzones
S-7 subzone 12" with 9 ft ceiling.
Typical 14 channels in 90 ft bay (4 structural bays); unassigned chan-
S-3 Channels
nels and access aisles outboard at sides of bay.
Typical 13 channels in 45 ft bay, narrow (2 ft) access aisles alternate
S-4 Channels
with channels for services.
Operation
Maintenance/Repair
Access to all areas is very good. Lighting level in service zones is very good. Receptacles are
available in service zone for tools.
Modifications/New Construction
Although contractors/installers have used numerous shortcuts (especially for communications),
overall subzones and channels remain well defined.
