- Description
- THIS NOTICE CONSTITUTES AMENDMENT NO. 1 TO THE COMBINED SYNOPSIS/RFP FOR MACHINING STUDY OF PM SUPERALLOYS IN SUPPORT OF SUBSONIC ROTARY WING PROGRAM. Companies shall acknowledge all amendment(s) in their quote. This notice serves as the official amendment to subject synopsis/RFQ and a written amendment will not be issued. The purpose of this amendment is to: Answer questions received before the August 10th Question Submittal Deadline. The due date for receipt of offers is not extended and remains 5:00 pm EST Friday, August 24th, 2007. -The following are the paraphrased questions and corresponding answers: ADMINISTRATIVE QUESTIONS Q1: What is the anticipated start date of the contract? A1: As referenced on page 24 of the solicitation, Offerors shall utilize October 1, 2007 as the estimated contract start date Q2: Is this solicitation restricted to small businesses? A2: The solicitation is not restricted to small businesses. However, small businesses may receive the applicable price evaluation adjustments listed on page 7 of the solicitation. Q3: Will NASA consider responses for 'Other Than Firm Fixed Price' contract types? A3: Due to the comparatively low procurement value, offers for 'Other Than Firm Fixed Price' contracts are highly discouraged. Offers submitted with 'Other Than Firm Fixed Price' contract types will still be evaluated. However, the alternate contract type will be noted during the evaluation process and may impact selection. TECHNICAL QUESTIONS Q4: Can previously created broached disk alloy samples be provided in Phase I? A4: NASA would need to know the exact composition and processing of the Phase I alloy. NASA will favor Phase I alloys similar in composition to NASA LSHR, in order to minimize risks of dissimilar machining responses between the two alloys. In both Phase I and Phase II, all microstructural, residual stress, and cold work data generated on NASA alloy LSHR will be publishable in open literature. Q5: If ITAR controlled material and design are provided, will NASA be willing to handle it accordingly? A5: The directive from the NASA Aeronautic program is to make available for open publication as much of NASA's funded work as possible. Because of this directive, we would prefer to minimize ITAR content of the work. Since it is NASA's intent to openly publish most of the LSHR work to be produced under this RFP, the ITAR content should be kept to a minimum. Q6: Is the microstructure of the LSHR pancakes uniform and will they be heat treated? A6: Yes, they would be supplied after powder metallurgy consolidation, extrusion, isothermal forging, solution and aging heat treatments to give a uniform microstructure, with normal solution quench cooling rate effects on precipitate microstructure/properties as functions of depth from the quenched surfaces. Q7: How big is the LSHR pancake that NASA will supply? A7: At least 6 inch diameter width, and 1.5" thick. Q8: Can NASA GRC provide the blank test specimen shapes from the LSHR pancakes? A8: The contractor would be responsible for removing the blanks from the NASA pancakes, according to mutually agreed drawings. Q9: Will test specimens have to be cut from specific areas in the LSHR pancake? A9: The entire pancake can be used for specimen removal. The location and orientation of each specimen blank within each pancake will need to be tracked. Since cooling rates within the pancake can be an important variable, NASA and the Offeror will agree upon the specimen layout prior to specimen blanking. Q10: Do you have any guidelines on the minimum amount of fatigue testing for Phase I? A10: The previously given answer with respect to the Offeror structuring the Phase I testing to comply with NASA SOW applies. Q11: Damaged/distorted surface layers from broaching can vary significantly. How much should the extent of formation of the damaged layer vary? Typical production rejection levels or more severe damage? A11: Levels will be chosen by NASA after consultations with the contractor. Q12: Are there drawings for the samples to be produced? A12: The selected Offeror and NASA will coordinate on potential sample configurations, and NASA will make the selection. Q13: Can TEM characterization be fitted into the budget? A13: NASA will not be doing TEM characterization. Q14: One of the deliverables at the end of Phase I is ‘One fractured half of each fatigue tested broach sample of OEM alloy’. How many samples do you anticipate? A14: This depends on how the Offeror decides to structure the proposal and how they propose to utilize the available resources within the schedule constraints. The governing criteria for the Offeror should be the following sentence taken from the SOW (Section II Technical Approach): ‘In order to examine the effect of these variables on the mean fatigue life, a limited number of low cycle fatigue tests will be performed using a configured specimen geometry selected by the Offeror in consultation with NASA.’ Companies shall provide the information stated in the synopsis/RFQ posted on the NASA Acquisition Internet Service (NAIS) on July 19th, 2007. Documents related to this procurement are available over the Internet. These documents reside on a World Wide Web (WWW) server which may be accessed using a WWW browser application.
