provided when the floor area to be served exceeds 1000
m (10,000 ft); or the horizontal distribution distance
to the work area exceeds 90 m (295 ft).” Both the commercial
building and healthcare facility TR designs shall
comply with TIA-569-D. The additional size for a healthcare
facility TR accommodates the additional systems
and provides room for growth (see Figures 2, 3 and 4).
Use the following guidelines when designing and
planning TRs in healthcare facilities:
• At least one TR must be included on each floor.
• The TR must serve a maximum area of 20,000 sq. ft.
(approx. 1,858 sq. m).
• The TR dimensions must meet the requirements of
the authority having jurisdiction (AHJ); if an AHJ
is not present, then the minimum floor dimensions
should be 12 ft. x 14 ft. (approx. 3.65 m x 4.27 m).
• The TR must be planned to support a 50 percent
growth factor of systems and services.
• Consider limitations where certain medical and
building systems cannot be located in the TR. In this
case, the room must be dedicated for the use of ICT
and related systems and not shared space with storage,
maintenance, janitorial and other applications.
• Working space in front and back of racks and
cabinets should be at least 3 feet (1 meter).

is 10 ft. x 10 ft. (approx. 3.04 m x 3.04 m) for every 10,000
sq. ft. (approx. 929.03 sq. m) of area. (Source: ANSI/BICSI

FIGURE 3: Healthcare TRs must include sufficient space for
specialty systems, such as nurse calls, biomedical devices, and
patient monitoring. The minimum floor recommendation is 12 ft. x
14 ft. (approx. 3.65 m x 4.27 m) for every 20,000 sq. ft. (approx.
1,858 sq. m). (Source: ANSI/BICSI 004-2018).

FIGURE 4: As an added challenge, certain hospitals will not
allow medical or building systems to be included inside the TR.
In this instance, a slip room design is required.
