E-MAIL: Faye Willis, fwillis@comdt.uscg.mil. This amendment changes the due date and answers questions received from potential offerors in response to the combined synopsis/solicitation under Request For Proposal (RFP) number DTCG23-99-R-T43010 to supply Medium Intensity Light Emitting Diode (LED) Buoy Lanterns. The RFP is modified as follows: The closing response date at Item 17, Description, has changed from July 23,1999 to July 30, 1999. The following questions were received: (1) Section 20.4 of DO-160D (conducted immunity) is specified, but what levels is required, multiple level in the spec. Do we need to meet all the levels? (2) Section 20.5 of DO-160D (radiated susceptibility) is specified, but what levels is required, multiple level in spec. Do we need to meet all the levels? ANSWER: Under Section 20.4 (conducted susceptibility), the test level is Category _V_. Under Section 20.5 (radiated susceptibility), the test level is also Category _V_. (3) We need to obtain a copy of U.S. Coast Guard Ocean Engineering specification G-SEC 491 as mentioned in the SOW. Can you please advise how we can obtain this. ANSWER: Correct Paragraph 5.2.1 and 5.3 to read _Specification G-SEC 498_. (4) This specification is for airborne equipment. Please confirm this is appropriate for the application. ANSWER: DO-160D, while specifically written for airborne equipment, is appropriate for this application. (5) Please advise if it is essential that one half of the Power Lead Connector be firmly attached to the lantern? Or is it acceptable for the power lead to leave the lantern via a cable gland and the Power Lead Connector to be at say 15cm from the lantern, in the Power Lead Cable, with total Power Lead Length being the specified 1 meter? If it is acceptable, would it be considered less desirable? ANSWER: The alternative is acceptable, and would not be considered _less desirable._ (6) Is the contractor responsible for all light testing? Is it possible for us to contract with the USCG R&D Center to do this testing? Under 5.2.1, the contractor is exempted only from 4.7 and 4.8. ANSWER: The contractor is responsible for completing the tests listed in Section 4.2, Examination, Section 4.4, Optical Performance, Section 4.5, Power Requirements and Section 4.6, Control System. With the exception of the optical performance tests, all of these are relatively easy to perform. The USCG R&D Center is not set up for outside contracting. (7) Under 4.7 Environmental testing, are the various test conditions and methods required of MIL-STD-202F available? ANSWER: As stated in Section 5.2.1 of the Statement of Work, the contractor is not required to perform the environmental testing under Section 4.7. Those tests are just to confirm that their product meets the requirements under Section 3.7 of the specification. Each offeror can follow its own QA procedures to ensure that their product will meet those requirements, they do not have to perform the exact same tests. Proposals are due IN WRITING no later than July 30, 1999, 3:00 PM to Commandant (G-ACS-1A/FW), U.S. Coast Guard Headquarters, 2100 Second St, SW, Washington, DC 20593-0001, Attn: Faye Willis Posted 07/15/99 (D-SN354420).
