Description

The purpose of this amendment is to clarify some concerns which have been addressed relative to this solicitation, as indicated below. All qualified responsible Small Business sources may submit a quotation which shall be considered by the Agency. An ombudsman has been appointed -- See Internet Note "B." Prospective offerors shall notify this office of their intent to submit an offer. It is the offeror's responsibility to monitor this site for the release of the solicitation and amendments (if any). Potential quoters will be responsible for downloading their own copy of the solicitation and amendments (if any). Any referenced notes can be viewed at the following URL: http://genesis.gsfc.nasa.gov/nasanote.html . CLARIFICATIONS TO QUESTIONS ASKED ARE AS LISTED BELOW. QUESTION 1: Details 1-1 and 1-6 "GFE." Does this mean Government Furnished Equipment? ANSWER 1: GFE is "Government Furnished Equipment" relative to design for design reference only. These items will not be supplied to the vendor. The vendor furnished item will be installed by NASA/MSFC personnel. QUESTION 2: Detail 1-2 Reducer P/N 6FCV-511RV. This number is obsolete according to our Distributor, Motion Industries. ANSWER 2: End User has talked to Windsmith, the reducer manufcaturer. End user was advised that the part inquestion 6FCV-5:1RU is available in right hand configuration. The number listed (6FCV-511RV) is not correct per the drawing callout. QUESTION 3: In the solicitation, the Bill of Materials calls for SAE 3120 steel. We have contacted all our material suppliers and they are not familiar with this requirement. We are wondering if this requirement is in error. ANSWER 4: The option to change material 3120 to 4340 was granted on 8/31/00. QUESTION 5: Drawing(s) for Ring Gear, Pinion Gear, Mounting Bracket and Drive Mounting Bracket do not provide finish call out (smoothness) nor preservative finish requirements (Black Oxide, etc.) for all machined surfaces. ANSWER 5: The finish is specified in the tolerance section of the title block on each sheet. The ring gear and pinion gear do not have a finish coating (paint or black oxide). All other parts are painted per a note on individual drawing sheets. QUESTION 6: Reduction Gear (Detail 1-2, Dwg. No. SK-H-1170, Page 1) indicates that the fan cooled version of the reduction gear will soon be obsolete. My distributor has suggested its replacement with the P/N 6CV-5:1-RU Reducer. Please advise if we may propose the replacement unit in lieu of the presently designated reducer. ANSWER 6: The unit specified P/N 6CV-5:1-RU is OK for use as a substitute only if the original Unit P/N 6FCV-5:1-RU is not available when ordered. QUESTION 7: Drawing SK-H-1170, Page 1, Detail 1-1 and 1-6 are noted as GFE. Will these components be provided to the vendor for fit check and final assembly, or will the delivered CLIN's be assembled/joined to them at MSFC after delivery from the vendor? ANSWER 7: The answer is NO. The vendor is to fabricate detail and sub-assembly (S/A) parts only. The vendor will assemble the ring gear S/A 3-101 as shown on sheet #3 for machining and dissemble for shipment. Final assembly will be performed at MSFC by in-house personnel. QUESTION 8: If assembly is to be accomplished at MSFC, is the vendor to perform the assembly at MSFC or will this be accomplished by MSFC personnel at no additional cost to the vendor? ANSWER 8: Any modifications to detail 1-1 and all final assembly work will be performed by MSFC in-house personnel. QUESTION 9: Drawing SK-H-1170, Page 3, Note 3-5 states: Each Section shall have (2) =-13 Taped Lifting Holes, the drawing does not provide/call out the desired lifting hole location. Please provide. ANSWER 9: The lifting holes are 3/8-16 and are called out in View "A" Note 3-5 is in error. QUESTION 10: Drawing SK-H-1170, Page 6, Detail 6-1 Description Reads: > x 15 -12 x 19 -- 3/8 LG. Please clarify/correct 15-12 to read 15-1/2 . ANSWER 10: The description on drawing for detail 6-1 should read: > x 15-1/2 x 19-3/8 lg. QUESTION 11: Drawing SK-H-1170, Page 7. Description below and to right of section B-B states: = -- 13 Tap Thru (7) holes require location from S/A 6-101 at assembly. Please clarify if the (7) holes called out on the 7-101 assembly drawing are the same holes identified on S/A 6-101 as the (7) .53 Drill Thru Holes. ANSWER 11: Yes, the =-13 holes on S/A 7-101 are located from the .53 diameter holes shown on S/A 6-101. One hole on lower left is dimensioned to provide relationship between the two parts. See plan view on sheet # 1 zone E8. QUESTION 12: Relating to previoius question (stated in # 11 above and also question # 7) please describe the customer anticipated deliverable configuration of the CLIN items to be delivered under the contract. ANSWER 12: The deliverable items are: 1 each, Ring Gear S/A 3-101 (dissembled for shipment); 1 each, Pinion Gear detail 4-1; 36 each, Gear Mounting Bracket (weldment) S/A 5-101; 1 each Drive Mounting Bracket (weldment) S/A 6-101; and 1 each, Drive Mount (weldment) S/A 7-101. QUESTION 13: We have found the gear cutting data to be incorrect -- could you please supply the corrected data. ANSWER 13: The only error in the gear data field that we could find was "mating gear date min. center distance" which is listed as 198.750 inches when it should be 99.375 inches. The gear data itself is correct. It was not clear by technical personnel as to which data field you were questioning to be in error. QUESTION 14: Please send the correct center distance. It appears to be about 100" off. ANSWER 14: As stated in question 13 above, the only error in the gear data field that we could find was "mating gear date min. center distance" which is listed as 198.750 inches when it should be 99.375 inches. The gear data itself is correct. It was not clear by technical personnel as to which data field you were questioning to be in error. QUESTION 15: Does the ring gear itself require paint? ANSWER 15: No. There is not a note requiring paint on either gear drawing (sheets 3 or 4). QUESTION 16: We recommend 4340 material. AISI 3120 steel is not available. Is it acceptable to use 4340? ANSWER 16: It is permissible to make the gear from 4340 material as suggested, so long as all bidders have the option to re-quote this material. ACCORDINGLY, ALL PROSPECTIVE CONTRACTORS ARE ASKED TO PROVIDE QUOTATION BASED ON THE 4340 MATERIAL, IN ORDER TO MAINTAIN CONSISTENCY. As stated above, the closing date is extended to CLOSE OF BUSINESS November 17, 2000. Any responses received after this date WILL NOT be considered. Additional questions will not be entertained.
