- Description
- This combined synopsis/solicitation replaces the sources sought notice posted for this item on July 24, 2004 in its entirety. The National Institute of Standards and Technology (NIST) has a requirement for a machined housing assembly for a Co-Conical Field Generation System (CFGS). This combined synopsis/solicitation for a commercial item and is prepared in accordance with the format prescribed in the Federal Acquisition Regulation (FAR) Subpart 12.6, as supplemented by additional information included in this notice and in accordance with the simplified acquisition procedures authorized in FAR Part 13. This announcement constitutes the only solicitation; proposals are being requested and a written solicitation will not be issued. The solicitation number is RA-1341-05-RP-1020 and is issued as a request for proposal (RFP). The solicitation document and incorporated provisions and clauses are those in effect through FAR Circular 2001-26. The NAICS code is 332721, and the small business size standard is 500 employees. The Co-Conical Field Generation System (CFGS) is a set of expanding cones. This requirement includes the building of a pair of cones, access doors, support structures, and alignment guides to test electromagnetic field Hazard probes. The smaller (inner) cone shall mount inside the larger (outer) cone with the alignment of a support structure then meet at the narrow tip in a microwave 2.92mm connector (specifically an Anritsu K-104F). The CFGS system shall guide RF energy from 10 MHz to 40 GHz. Drawings will be provided to interested parties upon request These drawings are detailed as five major areas of design: The Outer Cone, (consisting of 8 major sub assemblies), the Inner cone (consisting of 5 major sub-assemblies), Outer Cone 2 and Door Assemblies, the CFGS Support, and the Inner Cone Support. These drawings were designed using AutoCAD?s Inventor 8 ? to get full usage of design requirements Inventor 8 shall be used to view the design. The use of non-ferrous materials is absolutely critical in the inner surface of the Outer-Cones (Skin parts of Outer Cones 6, 7, 8, and 9) and the outer surfaces of the Inner Cones. The required blends of aluminum shall be adhered to. Critical machining issues: (1) Required Lathe ? a vertical lathe with a minimum of 60 inches of travel is required to perform the final finish cut on the outer cone. Adjacent sections shall be finished together to ensure a smooth transition between sections. For the final passes the doors shall be mounted in ?outer cone 2? and need to be machined so the inner surfaces of the doors are flush with the inner surface of ?outer cone 2?. (2) Inner-Cone - The outer surfaces of the Inner-Cones and mating surfaces between Inner-Cone sections shall conform to the surface finish requirements, parallel restraints and flatness in the drawings. The lack of a clean, machined finish will incur electro-magnetic losses and cause the system to be unstable. (3) Outer-Cone - The inner surfaces of the Outer-Cones and mating surfaces between Outer-Cone sections shall conform to the surface finish requirements, parallel restraints and flatness in the drawings. The lack of a clean, machined finish will incur electro-magnetic losses and cause the system to be unstable. (4) Outer-Cones 6, 7, 8 and 9 - The inner-surface profile is critical to making a smooth transition between a standard RF-microwave connector and the rest of the CFGS. The AUTOCAD INVENTOR (*.idw) drawings in cfgs\outter cone\bessel cones have a defined profile that shall be required during the machining process (not identified in the PDF version of the drawings). This profile shall be delivered in standard Machine-tool, CNC formatting in the distribution of the drawings. NIST will consult with contractor to determine actual format needed for the file to interface with the contractor?s available CNC equipment. (5) The mating between sections - The mating between sections of both the Inner and Outer Cone sections is critical. Specification of the actual diameter of each section is less critical than the smoothness of the critical surfaces between sections. Matched machining is required between sections to minimize this problem. Adjoining sections shall be mated together and final finish passes shall be made together so these critical surfaces are smooth. (6) Doors - The inner surface of the doors shall match the inner surface of the Outer-Cone. The mating specification on the top and bottom edges of the doors with the inner surface of Outer-Cone shall be adhered to maintain RF performance. Note: The dimensional tolerances on all drawings. These shall be adhered to - surface finish and section mating are critical to system performance. All offers shall contain detailed processes on how the machining will be performed. Offers shall describe how tolerances will be held (with special notes on the mating of the door sections to ?cone 2? and cone section to cone section interfaces). Machine-tools to be used shall be listed, with accuracy specifications, to verify ability of the offeror to construct the housing assembly. Details of machining and construction of the skin sections for outer cones 1 through 5 shall be described to determine suitability for use in electromagnetic energy propagation (see design considerations). Design considerations: 1. Skin construction - The design of the skin sections are left to the contractor. NIST suggests using the appropriate thickness of aluminum plate then bend the skin sections into rough shape, weld together with upper and lower rings and perform finish machining on the interior surfaces and ring ends. Other methods will be acceptable to complete the outer cones including machining out of solid stock and casting if tolerances can be held. Electromagnetic energy propagation will be adversely affected by seams and gaps between the skin sections. Efforts to minimize voids or gaps in the welding will result in better performance of the system. Final machining of the outer and inner cone sections shall not expose gaps between the skin sections or voids in the welds. For illustrative purposes ? There is a directory \pdf which contains PDF version of the drawings for initial analysis and review by the offerors it mirrors the directory structure of the actual drawings. The AUTOCAD INVENTOR drawings (.idw) in the \cfgs directory are the drawings which shall be used as the baseline for determination of compliance with specifications. The successful offeror should consider purchase of an AUTOCAD INVENTOR license to ensure that they can correctly implement all the drawings (The DRAWINGS ON CD MEDIA WILL BE PROVIDED UPON REQUEST.

The pdf directory contains the *.idw drawings in PDF format for easier viewing. The instructions directory contains the solicitations, clarifications, and instructions needed for building and assembling the system. The drawing list and locations are located in the file ?drawing list.xls? located in the instructions folder there are several folders called ?old versions? any *.idw files in these directories should be ignored. 2)The 0.001" tolerances to dimensions are not nearly as critical as the adherence to angle of cones, surface finish, and section mating. The profile tolerances in outer cones 1-6 are to prevent machining waves (a nice finish but on a wavy surface). Outer cones 7,8 and 9 shall be held dimensionally stable to the tolerances indicated as well as "inner cone 3" and "inside cone tip". NIST can accept the individual sections of outer cone 1-6 to be slightly longer or shorter as long as the 10 degree angle is met to tolerances, surface finish is met and interface between cones is within tolerance (in other words - we need a long smooth surface on the critical surfaces - if an individual section is longer than specified and an adjoining section is a little short ? NIST does not care as long as it is a smooth 10 degree cone with a conforming door). 3) The angle tolerance of the inner and outer cone can cause the large ends of the cones to be beyond tolerance specification. Angle tolerances and mating surface tolerances take precedence over dimensional tolerances of an individual cone section. 4) Outer Cones sections (5,6,7,8) may be bolted together (semi permanently). NIST assumes that a manufacturer may wish to bolt the cones together (semi-permanently) to ensure a repeatable smooth surface (it cannot be changed by disassembly). NIST can accept a bolted solution as long as the system can be assembled without risk of damage to the inner cone sections. The cones will be broken up to facilitate assembly in the Air Force Metrology Lab. There is a two foot high floor with 4 foot by 4 foot opening in which the cell fits into. The drawings of the room and floor are on the package CD - If an assembly can be made of the entire system with the floor installed and under the 13'4" crane (as shown in the attached drawing 41H5novotny2 Model w hoist.pdf), it will be acceptable to bolt the cones together. Refer to the following files in the instructions directory of the CD: Rough assembly.avi; ( a movie file of the CFGS being pieced together)41H5novotny Model (1).pdf ;( a top drawing of the cone in the AF LAB)41H5a202 Model (2).pdf; ( a side view of the cone in the lab)41H5novotny2 Model w hoist.pdf; ( a drawing with the hoist to lift the larger pieces) Outer Cones 3 and Outer Cone 4 may be similarly bolted together if the combined weight does not exceed 400 pounds and system assembly can be performed. 5) From a microwave standpoint, gold plating the interfacing surfaces of the outer and inner cone will probably improve RF performance - it would be desirable and improve the quality of the offer if it is not cost prohibitive. This would be a plating of the connecting surfaces between outer cone 2 and outer cone 3 (not the entire cone ? just the surfaces between cones). A further note, completely plating the following parts shall be included in the offer: Inside cone tip.pdf (includes inside cone tip and 0.012 tip (prior to insertion into the inside cone tip)) Cone 9.pdf Nominal plating thickness: 5-10 micro-inches of gold ? to ensure long term bonding of the gold to aluminum ? a intermediate plating between the gold and aluminum may be considered. 6) All aluminum pieces (outer and inner cone and door) SHALL be made with a non-ferrous aluminum mix. NO MATERIAL WITH IRON may be used unless specifically stated (inner cone supports and CFGS support). The cone tip should be made of RF-connector grade beryllium-copper (as noted). Conductivity is important and material blends like 6061, 7071 are acceptable. SPECIFIC ALUMINUM BLENDS FOR ALL CONE PIECES (INNER AND OUTER) SHALL BE OUTLINED IN THE OFFEROR?S PROPOSAL. NIST can verify acceptability of blends if requested. 7) The parts in ?inside cone tip.idw (or inside cone tip.pdf) ? has the largest possibility of damage ? there should be 5 pieces of the ?inside cone tip assembly? delivered as part of the project. This includes 5 pieces of the inside cone tip joined to 5 pieces of the .012 pin. 8) The beveled end of the .012 pin SHALL NOT be inserted into the ?inside cone tip?. Beveling of the other end, to ease insertion into the ?inside cone tip? is acceptable. Proposals shall clearly specify delivery time. The Government desires delivery within 150 days. While delivery within the desired period is not an absolute requirement, proposals offering a delivery longer than 240 days from date of award will not be considered . Award shall be made to that offeror whose proposal contains the combination of those factors offering the best overall value to the Government. This shall be determined by comparing differences in the values of technical and management features with differences in cost to the Government. In making this comparison the Government is more concerned with obtaining superior technical or management features than with making an award at the lowest overall cost to the Government. However, the Government shall not make an award at significantly higher overall cost to the Government to achieve slightly superior technical or management features. Offers shall be evaluated in accordance with the Test Program procedures at FAR 13.500. Evaluation Factors include: (A) TECHNICAL: Ability of Machine Shop to Perform Tasks; Ability to provide adequate finishes and tolerances; Ability to assemble and test; and General quality, responsiveness of the offeror?s proposal, (B) PAST PERFORMANCE and (C) PRICE. Evaluation factors are listed above in their order of importance. Technical and past performances, when combined, are significantly more important than price. Technical proposals shall include identification of compliance with the specifications and drawings. Offerors shall also provide product information sheet(s) for their materials. For the evaluation of Past Performance, the offeror shall provide at least three references, along with their respective addresses, phone numbers and e-mail addresses. Note that the Government may also contact references other than those identified by the offeror and use the information obtained in the evaluation of the offeror's past performance. In order that the technical proposal may be evaluated strictly on the merit of the offer submitted, no contractual price information shall be included in the technical proposal. A separate business proposal shall be provided that includes the following: (1) a price proposal and (2) a completed FAR 52.212-3 Offeror?s Representations and Certifications - Commercial Items, referencing solicitation number RA1341-05-RP-1020.
