COMMERCE BUSINESS DAILY ISSUE OF JULY 12,1996 PSA#1635US 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 (TPMS) SOL 52-DGNW-7-90004 DUE 081596 POC Robert R. Curtis,
Contract Specialist, or John O. Thompson, Contracting Officer, by
telephone at (301) 713-0823 or by fax at (301) 713-0806 The text in the
original notice was published on June 27, 1996 and republished on July
2, 1996, however, both were 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-upgenerator 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 KVA at 0.8
power factor for a continuous load of 208 +/- 5% Volts, 3-phase,
4-wire, 60 +/-5% hertz at an outdoor temperature of -40 degrees C to
+49 degrees C, without derating, from mean sea level (MSL) to 3300
meters above MSL. Ride-through, the transition between commercial and
back-up power, at continuous load, must be at least 12 seconds, for up
to 40 transition events per day, with no degradation of voltage or
frequency. The TPS must be capable of supplying overload currents of at
least 600% of the continuous load for 16.7 milliseconds and 150% of the
continuous load for 30 seconds, without the use of bypass mode. The
voltage dip, during the transient period, caused by the application of
a 0.4 power factor lagging load drawing 200% of the TPS's rated
current, shall not exceed 5% of the TPS's rated voltage. The output
voltage waveforms shall not exceed 3% THD at continuous load, with 50%
of the load being nonlinear and no single harmonic more than 1% of
fundamental frequency, from 60 hertz to 1 megahertz. The output
direct-axis subtransient reactance must be 0.2 per unit, maximum and
the direct-axis transient short-circuit time constant test must be 0.5
seconds, minimum. The TPS inputs and outputs shall be protected to
withstand, without damage, IEEEC62.41 Category C (exposed outdoor
feeders) waveforms. While the overall shelter space is approximately 24
feet by 12 feet, the available interior TPS installation space
(including space for controls and enclosures) is limited to 11 feet in
length by 8 feet in width by 8 feet in height. Four-foot wide access
doors have also been established for each side entrance to the
installation space. The Government may order on-site maintenance after
installation at each site for the 10 year term of the contract. Depot
repair services will also be required. The contractor shall provide
adequate facilities for repair of any aspect of the TPMS. The
contractor will also be required to provide additional individual
components, including the TPS, that may be ordered separately within
the minimum-maximum order limitations to be established within the
solicitation. This effort will also include all site preparation and
construction work at each of the WSR-88D sites. The magnitude for the
construction component of this solicitation is between $5,000,000 and
$10,000,000. The site locations may include the continental United
States, Alaska, Hawaii, Puerto Rico, and specified overseas locations.
As an estimated 260 construction blueprints are associated with this
project, the Government will not provide any interested party with such
blueprints, but rather will provide the points-of-contact from several
sources where any interested party may seek to procure these drawings
after the solicitation is issued. Any offeror proposing as the prime
contractor and submitting its complete technical proposal in accordance
with the instructions identified in Section L of the solicitation will
be issued all necessary Davis-Bacon wage determinations for subsequent
submission of price proposals, which are anticipated to be due
approximately three weeks after technical proposal closing date. A
pre-proposal conference will be held approximately two weeks after the
release of the solicitation. To maximize subcontracting opportunities
for all potential prime contractors, any firm interested in proposing
as a prime contractor for this procurement should specifically
identify this intent in its written request for solicitation.
Additional required information from all interested parties includes
complete identification of points-of-contact, telephone and fax
numbers, and business size. All requests for this solicitation must be
in writing to the point of contact and address cited above. Telephone
requests will not be honored. See Note 26. (0192) Loren Data Corp. http://www.ld.com (SYN# 0051 19960711\N-0001.SOL)
