NASA/GRC has a requirement for Ice Droplet Measurement Instruments.
1. 1 ea. Cloud Droplet Probe (CDP)
2. 1 s2. Spare CDP Connector
3. 1 ea. Cloud Imaging Probe (CIP)
4. 1 ea. Greyscale Spinning Test Disc
5. 1 s2. Spare CIP Connectors
6. 1 ea. Precipitation Imaging Probe (PIP)
7. 1 s2. Spare PIP Connectors
8. 1 ea. Onsite Training
The instruments required to calibrate droplet sizes in the Icing Research Tunnel (IRT) need to be replaced. The full range of droplet sizes generated is approximately 2 – 1200 microns; therefore multiple probes are required to measure the different size regimes. The probes must remain free of ice contamination during hours of icing spray operation. The probes must be able to operate accurately in an environment of -10°C and 200 kts. The current optical particle sizing probes, a Forward Scattering Spectrometer Probe (FSSP) and Optical Array Probe (OAP), need to be replaced with the next generation of optical instruments. These new probes will need to be compatible with the existing data system, which will not be replaced at this time.
The three probes made by Droplet Measurement Technologies, Inc. (DMT) are the only like-kind instruments that meet these criteria. The Cloud Droplet Probe (CDP) measures droplets in the 2 – 50 micron range; the Cloud Imaging Probe (CIP) measures the 15 – 930 micron range and the Precipitation Imaging Probe (PIP) measures the 100 – 6200 micron range.
NASA/GRC intends to purchase the items from Droplet Measurement Technologies, Boulder Colorado. The Icing Research Tunnel is in the process of upgrading its entire present droplet sizing measurement instruments. The present instruments are outdated and are in need of replacement. The new instruments from Droplet Measurement Technologies (DMT) are compatible with our present data acquisition/software systems and tunnel mounting systems. It has been found that it would be too costly and not in the best interest to the Government in funding and time to obtain a new vendor and the possible cost savings does not validate the competition.
The Government intends to acquire a commercial item using FAR Part 12.
Interested organizations may submit their capabilities and qualifications to perform the effort in writing to the identified point of contact not later than 4:30 p.m. local time on Friday, September 17, 2008. Such capabilities/qualifications will be evaluated solely for the purpose of determining whether or not to conduct this procurement on a competitive basis. A determination by the Government not to compete this proposed effort on a full and open competition basis, based upon responses to this notice, is solely within the discretion of the Government.
Oral communications are not acceptable in response to this notice.
All responsible sources may submit an offer which shall be considered by the agency.
An Ombudsman has been appointed. See NASA Specific Note "B".
