21.3
Locate regeneration alarm bell in boiler plant office.
21.4
Provide emergency shower and eye/face wash (P-707) adjacent to
equipment.
22.
REAGENT GRADE WATER SYSTEM
22.1
As water analysis dictates, provide floor space for central
reagent grade equipment. Design the piping system from the
equipment room to the outlets. Equipment (reverse osmosis,
deionizer or combination) will be furnished by the VA Medical
Center. Design piping to provide continuous loop to within 150 mm
(6 inches) of outlet or to the base of the faucet.
22.2
Assign floor space for storing 30 days supply of regenerant
chemicals.
22.3
Provide emergency shower and eye/face wash (P-707) in equipment
room.
22.4
Coordinate with HVAC to provide adequate negative pressure
ventilation.
22.5
Provide chemical resisting piping and drains.
23.
SEISMIC REQUIREMENTS
23.1
GENERAL:
A.
Earthquake-resistive design shall comply with the requirements
of Design and Construction Procedures, "Natural Disasters Non-
Structural Resistive Design"; the latest edition of "Seismic
Design Requirements"; and the Uniform Building Code (UBC)
published by International Conference of Building Officials
(ICBO).
B.
Plumbing equipment and piping shall be braced in accordance
with the most current edition of Seismic Restraint Manual
Guidelines for Mechanical Systems (SMACNA) and National
Uniform Seismic Installation Guidelines (NUSIG).
C.
Unless otherwise shown by SMACNA or NUSIG, provide required
details and structural calculations to completely address
seismic bracing requirements. See paragraph 23.4
"CALCULATIONS".
D.
SMACNA does not cover all conditions such as, providing
bracing details for seismic restraints of equipment or details
of flexible joints when crossing seismic or expansion joints,
or bracing of in-line equipment, etc.
E.
Coordinate earthquake-resistive design with the project
Professional Structural Engineer for appropriateness and
soundness.
F.
Both SMACNA and NUSIG list conditions under which seismic
bracing may be omitted. However, a design professional may
revoke these omissions on an individual project basis.
