E-MAIL: Rachel R. Khattab, rkhattab@mail.arc.nasa.gov. THIS NOTICE CONSTITUTES AMENDMENT NO. ONE (1) TO THE COMBINED Synopsis/RFO FOR AUTOCLAVE SUPPLEMENTED WITH ADDITIONAL INFORMATION CONTAINED IN THIS NOTICE. Companies shall acknowledge all amendment(s) in their offer. This notice serves as the official amendment to the subject solicitation and a written amendment will not be issued. The purpose of this amendment is to provide additional information and clarify information based on questions received. The following requirements constitute a change in the Statement of Work (SOW). I. Proposals to provide a refurbished autoclave will be considered and evaluated along with proposals to provide a new autoclave (See FAR 52.212-1 Information on Mulitple Offers). Consistent with commercial practices, offerors shall identify the history and condition of all refurbished components. II. In section A1 of the SOW, under electrical feed-through, the requirement to provide eight (8) pressure sensors has been changed. Two (2) pressure sensors are the minimum requirement. They should be placed under the vacuum bag in the autoclave. The following information is provided for clarification and does not change the SOW. A. In section A1, Construction Requirements, Temperature should be 650 degrees Farenheit maximum internal and external shell temperature not to exceed 120 degrees Farenheit. Heat ramp of 20 degrees Farenheit per minute. The following questions and answers are provided for informational purposes and do not change the requirements as stated in the SOW. Question 1. Penetration distribution -- Can the requested distribution be achieved inside of the vessel? Response: The requested distribution can be achieved inside of the vessel; i.e., one or two penetrations with raceways inside to achieve the "uniformity distributed criterion", as long as the raceways are not too obtrusive on the ID of the autoclave. Question 2. Why do we need eight (8) pressure sensors? Is it expected that pressure changes will occur along the length due to the functional process of the autoclave? See the change in requirements stated above in item II. Question 3. What is the requirement for temperature distribution in the vessel? (Both axially and radically) Response: The requirement for temperature distribution in the vessel (both axially and radically) should be plus or minus 10 degrees. Question 4. What is the minimum temperature required at the 10 F/min.? Response: The minimum temperature required at the 10 degrees F/min. is 75 degrees Farenheit. Question 5. What is the nature of the "composite parts" to be included in the vessel -- size and mass? This is important in the heating and sizing. Response: The nature of the composite parts to be included in the vessel are unknown, since this is an R&D facility. Molds could be aluminum or nonmettalic large or small. Question 6. The 650 F temperature specified for the internal of the vessel shall be measured where? Vessel, environment or part. What is the acceptance tolerances on this temperature? Response: The 650 degrees F temperature specified for the internal of the vessel shall be measured throughout the vessel. Acceptance tolerances on this temperature are plus or minus 10 degrees F. Question 7. What is the overall dimensions of the cart (both internal and external)? Response: The overall dimensions of the cart (both internal and external) have not been stated, so the cart would be a standard part. It is estimated to be about 18 inches off of the bottom of the autoclave, whatever would give about a 3-4 foot bed size and take advantage of the full length of the autoclave. Question 8. What is the minimum internal pressure? Response: The minimum internal pressure is atmospheric at sea level. Question 9. Who supplies the compressor? Response: The compressor is to be supplied by the autoclave manufacturer. This should be capable of maintaining 90 psi internal pressure. Question 10. Is there a need for a vacuum pump? If so, who supplies? Response: A vaccuum pump is to be supplied by the autoclave manufacturer, capable of 30 hg. Question 11. Are there any requirements for positioning equipment for the cart? e.g., is it motor driven? Response: The cart will be moved manually. It need not have a motor. Question 12. What is the acceptance criteria for pressure temperature and leakage? What about acceptance test requirements -- are there any other than those required by the ASME Code? Response: The acceptance criteria for pressure temperature and leakage and acceptance test requirements are required by the ASME Code. Question 13. What is the minimum size and shape of the required automatic door? Response: The required automatic door should be sized to take full advantage of the internal dimensions of the autoclave. Question 14. Who supplies the compressed nitrogen? Response: NASA will supply the compressed nitrogen, either in six pack bottles or by tank. Question 15. What quality assurance requirements/programs are required other than our own? Response: Quality assurance requirements are as stated in the FAR, regarding commercial items. The due date forreceipt of offers is not extended. Offers shall provide the information stated in the synopsis/RFO posted on the NASA Acquisition Internet Service (NAIS) on July 21, 1998 and published in the CBD on July 23, 1998. Documents related to this solicitation will be available over the Internet. These documents are in Microsoft Office Suite (Word 6.0, Excel 5.0, or PowerPoint 4.0) format and reside on a World Wide Web (WWW) server, which may be accessed using a WWW browser application.
