COMMERCE BUSINESS DAILY ISSUE OF APRIL 24,1997 PSA#1831Naval Surface Warfare Center, Carderock Division, 9500 MacArthur Blvd.,
West Bethesda, MD 20817-5700 A -- MODEL TESTING SERVICES SOL N00167-97-R-0034 DUE 061597 POC David
Tychman, 301-227-3475, C.O. C. Joan Miles, 301-227-1159 MODEL TESTING
SERVICES to support Naval Surface Warfare Center, Carderock Division
(NSWCCD) research on the hydrodynamics of ships, submarines, and other
craft. The Government estimates that it will need approximately 31,222
man-hours per year (15 man-years/yr.) over a five year period on an
indefinite delivery/indefinite quantity (IDIQ) basis for a total
estimated effort of 156,110 man-hours (75 man-years). Both experienced
personnel and extensive fabrication and test facilities will be
required to successfully perform this contract. Contractor experience
will be a significant evaluation factor for award. Offerors unable to
demonstrate access to required fabrication and testing facilities will
not be considered for award. Personnel, manufacturing and testing
facilities (excluding the water tunnel) must have, not later than
contract award, a security clearance which allows the contractor to
perform Government classified work up to the CONFIDENTIAL level.
Offerors shall be required to demonstrate two principle capabilities in
order to receive this contract award; 1)scale-model fabrication and 2)
hydrodynamic testing. First, the offeror shall demonstrate that, with
his own facilities, he has the personnel and the physical capability
to design, engineer, and fabricate scale models of ships, submarines,
and advanced craft up to 40 ft. in length using composite materials
(e.g. fiberglass), wood, and/or aluminum material. Shop facilities must
include such items as Computer Numerical Control (CNC) machines, manual
machine tools, hand tools, lifting and inspection equipment, and layout
tables capable of handling models up to 40 ft. in length. The offeror
must have the capability to meet tolerances of a) plus or minus 1/8 in.
on model length, and b) plus or minus 1/32 in. normal to the contour of
the surface, and surface roughness of 63 micro inches or better. The
offeror must also have the capability to fabricate propulsors (stators,
ducts, and rotors) and open propellers that range in diameter from 10
to 48 inches, using both th monoblock and inserted blade techniques.
Capability is required to fabricate monoblock propulsors with diameters
of up to 24 inches using CNC machines. Offerors must be capable of
constructing propulsors from such materials as aluminum, bronze,
Plexiglas, and other reinforced plastics. Propulsor tolerances are as
follows: i) plus or minus 0.003 in. for diameter, chord length, camber,
and thickness, ii) plus or minus 6 minutes of angle for propeller
pitch, and iii) plus or minus 8 micro-inches (64 RMS or better) for
surface finish. Second, offerors must have the personnel and test
facilities capable of conducting hydrodynamic and hydroacoustic
evaluations of ship-hulls and propellers. Offeror test facilities must
be capable of conducting four main types of tests and meet the
following requirements for each test type: a) Resistance and Powering
Tests (test surface and submerged models of up to 20 ft. in length at
speeds up to 7 knots) b) Stability and Control Tests (test 15 ft long
models at speeds up to 6 knots, and produce vertical oscillations of up
to plus or minus 1.0 ft. amplitude) c) Seakeeping Tests (test 10 ft.
long models at speeds up to 5 knots, and generate regular and irregular
waves to permit testing in head and following wave directions) d)
Cavitation Tests in water tunnel (attain a range of tunnel pressures
from 10 to 40 Pounds Per Square In. Absolute (PSIA) with tunnel
velocities up to 25 fps (feet per second)). Cavitation tests include
testing propellers up to 12 in. in diameter and testing with inclined
shafting for the propeller. Complete facility and personnel
requirements are detailed in the solicitation. Offerors interested in
receiving a copy of the solicitation when it is issued should submit a
written request by mail to: Commander, NSWCCD, Attn: David Tychman
(Code 3322), 9500 MacArthur Blvd., West Bethesda, MD, 20817-5700, or by
FAX to: 301-227-3638, and reference the solicitation number. (0112) Loren Data Corp. http://www.ld.com (SYN# 0009 19970424\A-0009.SOL)
