E-MAIL: Mary Lou Guthrie, MaryLou.Guthrie@grc.nasa.gov. RFQ3-125027 THERMAL SPRAY ROBOT Amendment #1 Description: PART 1 SPECIAL NOTICE: The due date for quotations is extended by 5 days to Wednesday, June 23, 1999. PART II RESPONSES TO RFQ QUESTIONS Question #1 Specifications did not include robot and turntable capabilities. It also did not include Dust Collector size and specifics about the exhaust plenum. Are there any requirements about integration of this equipment with the process equipment? Answer to Question #1 The specification contains adequate information regarding the robot/turntable capabilities. This robot system will be specifically used for plasma spraying. Specifications regarding the Dry Dust Cartridge Collection System show approximate dimensions and blower unit size. Item 11 should read: "DURABLE ENAMEL PAINT FINISH OVER MILD STEEL CONSTRUCTION". The exhaust plenum should read: "SEVEN FOOT BY FIVE FOOT COLLECTION FACE AREA". There is no requirement for thermal spray process equipment. Question #2 The Specification requires that the dust collector be of stainless steel construction. While this is possible, a collector of this type does add considerable expense and a longer delivery time. Would NASA be open to a quotation for a standard mild steel collector with the option of stainless steel construction? Answer to Question #2 As mentioned in the answer to Question #1, the specification should have read "MILD STEEL CONSTRUCTION", NOT STAINLESS STEEL. Question #3 The specification for the robot notes that the maximum weight of the plasma generator and cables does not exceed 50 pounds. Can this weight be broken down to the weight of the generator, mounting bracket and cables? This information is critical in determining the actual weight being added to the end of the robot arm, which in turn determines the size of the robot required. Answer to Question #3 Considering the weight of the plasma generator and the mounting bracket to size the robot arm, the total weight is ~ 18 lbs. Question #4 A keyboard and CRT for programming and monitoring the robot in operation has been requested. Would NASA consider a touch screen in place of the keyboard and CRT? The touch screen concept has been supplied to other customers and as such may be a more cost-effective option to the keyboard/CRT. Answer to Question #4 A touch screen concept in lieu of a keyboard/CRT type of system is acceptable provided that all specifications are met. Question #5 The RFQ is noted as a "total small business set-aside". Would this set-aside requirement preclude a large business from bidding on and being awarded the contract? Answer to Question #5 Yes. The total small business set-aside requirement only allows bids from small businesses. A small business for this SIC Code, 3599, is one who has 500 or less employees. If we do not receive any reasonable, responsive bids from small businesses, we will readvertise this requirement as unrestricted. Question #6 Is there a preference for a floor mounted robot or for a robot suspended overhead from a steel framework? Answer to Question #6 We havea preference for a floor mounted robot arm. Question #7 Who is to supply the adapter bracket that mounts the spray nozzle to the end of the robot arm? Does NASA already have this? If so, is it designed for a particular hole pattern? Answer to Question #7 NASA will engineer any mounting fixtures necessary to affix the plasma generator to the robot arm. Specifications are revised per this Amendment. Posted 06/18/99 (D-SN344727).
