Utility Plan Notes
Cystoscopy Room
Note 1
Exhaust Air Grilles - Provide a minimum of two exhaust air grilles in this operating room. If only two grilles
are provided, locate them opposite each other. Where there are more than two exhaust grilles, they are to
be centered on each of the walls of the operating room. The bottom of each exhaust air grille is to be seven
inches above the finished floor. See the HVAC Design Manual for additional information
Note 2
Electrical Power/Ground Module - A separate power/ground module Is to be placed near the center of each
wall of the operating room. Each power/ground module is to have 3 duplex power receptacles and 1
grounding receptacle, These power/ground receptacles are to be located 435mm (18 inches) above the
finished floor. See the Electrical Design Manual.
Note 3
Retractable Utility Column Provide connections on utility column as delineated in Chapter 286, Equipment
Guide List.
Note 4
HVAC Controllers - Provide one of the two following systems for controlling room temperature and humidity,
in the design of the mechanical system. The first system is indicated on the utility plan below. It involves
locating a thermostat, a humidistat, and a recorder in the operating room. The second system involves
temperature and humidity sensors located in the operating room with a recorder located remotely. See the
HVAC Design Manual for Hospitals and MCS, Division 15 for additional information.
Note 5
Nitrogen Control Panel - For information regarding this panel see NFPA 99, Chapter 4 and Master
Specifications, Section 15491.
Note 6
Isolated Power Unit - Each of the isolated power units is to serve two adjacent walls. For this reason the
units are to be located near the corners of the room and diagonally opposite from each other. See Electrical
Design Manual, Chapter 11, for more Information regarding isolated power.
Note 7
Computer terminal - Utility requirements for the in-room computer terminal are to be determined by the
VAMC based upon the computer system to be used. This information is to be given to the A/E for
incorporation into the construction documents, The printer for the in-room computer terminals is to be
located remotely.
Note 8
Laser Panel - It is understood that air-cooled lasers are soon to replace water cooled lasers. For this
reason, the future impact of air cooled lasers on the design of the HVAC system must be considered by the
designer. In spite of this anticipated change, it is the policy of the VHA program official that water service is
to be provided in any operating rooms where existing water cooled lasers are to be continued in use.
Note 9
Zone Valve Box - A separate zone valve box is to be provided for each operating room (anesthetizing
location) in accordance with NFPA 99 - Chapter 4. This cabinet is to be located in the peripheral corridor
near the door to the operating room it serves. See MCS. Division 15 for a description.
