COMMERCE BUSINESS DAILY ISSUE OF JULY 2,1996 PSA#1628US Department of Commerce/National Oceanic and Atmospheric
Administration, PGAS/Procurement Operations Division, 1325 East West
Highway - Station 4301, Silver Spring, Maryland 20910-3283 N -- INTEGRATION AND INSTALLATION OF TRANSITION POWER MAINTENANCE
SHELTERS SOL 52-DGNW-7-90004 DUE 081596 POC Robert R. Curtis, Contract
Specialist, or John O. Thompson, Contracting Officer, (301) 713-0823
The text in the original notice published on June 27, 1996 was
inadvertently truncated. The complete intended text of the original
transmission follows. The Government intends to procure approximately
130 Transition Power Maintenance Shelters (TPMS), over a five year
period under an indefinite quantity contract in support of National
Weather Service (NWS)/Tri-Agency Doppler Weather Surveillance Radar
-1988 (WSR-88D) systems. Each TPMS will be required to provide
uninterrupted conditioned power to its WSR-88D system during cutover
between commercial power and back-up generator power. The TPMS is a
stand-alone facility consisting of the following: a precast concrete
shelter, a Transition Power Source (TPS), an environmental control
unit, an electric toilet unit, storage cabinets, and a workbench. The
TPMS will provide limited storage and working space. A central
component to be provided by the contractor is the high daily
duty-cycle, long ride-through TPS that uses motor-driven technology
compatible with the existing WSR-88D standby diesel generator. In
addition to the concern for compatibility between the TPS and the
existing generator, the NWS is concerned that necessary environmental
conditions for energy storage batteries cannot be ensured and that
routine servicing at remote locations cannot be guaranteed during the
winter season. Notwithstanding these concerns, offerors are advised
that all types of technologies will be considered for contract award.
The Government intends to conduct two-step pre-award testing on the
TPS, first, at the contractor's facility, and second, at the Norman,
Oklahoma WSR-88D site. The WSR-88D radar system has a complex power
load not commonly found in industry. The WSR-88D's existing power
source is a commercial utility grade 75 KVA, 5.75% per unit impedance
transformer supplying 208 Volt, 3-phase, 4-wire, 60 Hertz input power
with backup power typically furnished by an emergency standby diesel
generator, Kohler Model Number 80ROZJ81, rated for 80 KVA. The system
load consists of WSR-88D support electronics requiring UPS protection,
including a Westinghouse 750 KW peak power pulsed klystron
transmitter, two 90 Amp DC servo drive motors moving an 8-ton antenna,
and two 5-ton air conditioners. The air conditioners do not require
TPS protection. The TPS must supply at least 35 KV (0180) Loren Data Corp. http://www.ld.com (SYN# 0072 19960701\N-0001.SOL)
