Amendment 3 Q: Sheet 1 carries a marked note that the U-Channel is not shown correctly in Detail A or the Top and Bottom views. Can the Government confirm/issue a corrected Detail A and Top/Bottom view for the U-Channel (Find No. 3, Dwg. 17-3-4854) before award, or advise which view governs in the interim? A: Drawing 17-3-4854 was revised and an updated drawing package was uploaded to the announcement. Side view in 17-3-4850, Detail B, shows the correct positioning of U Channel, 17-3-4854. Q: The U-Channel detail sheet specifies cross-section (2.00? 1.00?, .125? wall) but does not dimension overall cut length. Please confirm the required finished length for the four U-Channel pieces called out on the weldment parts list (17-3-4851). A: Drawing 17-3-4854 was revised and an updated drawing package was uploaded to the announcement. Q: Drawing calls out Aluminum 6061-T6 and 6063-T5 per ASTM B221 throughout.

A: Unless otherwise stated, DFARS 252.225-7009 would not apply for purchases under the Simplified Acquisition Threshold (SAT). Mill test reports/certificates of conformance are only required if stated on a purchase order. Q: Removable panel spacer is specified as Nylon 6 (polyamide), off-white. Please confirm whether a specific commercial grade/durometer or flame-retardancy rating is required, or whether generic Nylon 6 stock is acceptable. A: For this product, generic Nylon 6 stock is acceptable. Q: Please confirm acceptable substitute/equivalent aluminum tempers or alloys (e.g., alternate 6000-series) in the event of raw-material supply disruption, and the process for requesting a material deviation. A: Material deviations should be requested in writing (email), with supporting documents (material data, mark-up of drawings) and will require acceptance by the product engineers (final customer). Q: Drawing calls for welding IAW ANSI D1.2. Please confirm whether a specific filler alloy (e.g., 4043 vs. 5356) is required or left to the fabricator's WPS, and whether WPS/PQR must be submitted for Government approval prior to production. A: For this product, the government does not require approval of WPS and PQR. Other products may have additional welding requirements stated on the drawings or purchase order. Q: Please confirm the required weld inspection method and acceptance criteria visual only per AWS/ANSI D1.2, or is additional NDE (e.g., dye penetrant) required on any joint? A: For this product, the government does not require additional NDE. Other products may have additional inspection requirements stated on the drawings or purchase order. Q: Rivets (MS24243/5A304, MS24243/5A406) and rivet-mount nut (MS21075-4N) are called out by standard number only. Please confirm no additional finish/plating beyond the standard MS material finish is required. A: No additional finish/plating beyond the standard MS part finishes unless stated on drawing. Q: Please confirm whether any non-destructive inspection (NDI) beyond standard ISO 9001:2015 dimensional/visual inspection is required (e.g., ultrasonic, radiographic, or dye-penetrant), and identify the applicable acceptance standard. A: NDI beyond dimensional/visual inspection is not required unless called out on a drawing or required on a purchase order. Q: Is a First Article Inspection (FAI) required prior to release of production quantities? If so, please identify the required FAI report format and submission timeline. A: First article submission is not required unless requested as part of a purchase order. Q: Please confirm the exact ink product or acceptable equivalents for the MIL-STD-130 marking requirement (25-high Gothic characters, black epoxy ink) or confirm any commercial equivalent meeting MIL-STD-130 is acceptable. A: Unless the drawing states specific requirements for ink, commercial equivalent meeting MIL-STD-130 is acceptable. Q: Please confirm required packaging/preservation level for shipment (e.g., MIL-STD-2073-1) and destination(s)/CLIN structure. A: Unless requirement for MIL-STD-2073 packaging is stated in a purchase order, then commercial packaging is acceptable. Destination will be specified in the purchase order. (Most likely it will be Natick). Q: Please confirm total estimated quantity, delivery schedule, and whether the acquisition includes option quantities or is a base-plus-option/IDIQ structure. A: Sources sought posting is for market research only. Delivery schedule and contract structure not determined. Q: Please confirm the small-business set-aside status of this acquisition (e.g., WOSB set-aside vs. full-and-open with WOSB consideration) and applicable NAICS size standard. A: Small-business set-aside status not determined. Sources sought posting is for market research only. Q: Please confirm the data rights/distribution status of Dwg. 17-3-4850 and subordinate details for purposes of subcontracting any detail-part fabrication. A: Dwg. 17-3-4850 is Distro A Unlimited release Amendment 2 Update to ECU frame drawing package updated with a change of 17-3-4854. This part was redesigned recently during fabrication due to a few issues and inconsistencies. Amendment 1 Removed the requirement to specifically cost out fabrication of the ECU Frame Assembly per the attached drawing / technical data package (17-3-4850) as it is representative of current needs as well as any discounts provided for purchase quantities in excess of a single unit. SYNOPSIS: This Sources Sought Announcement is to assist the US Army Combat Capabilities Development Command - Soldier Center (DEVCOM-SC) to identify potential sources to provide Custom Metal Fabrication Servies in support of the Soldier Sustainment Directorate Prototyping Branch. Background: The Government (DEVCOM Soldier Center / Soldier Sustainment Directorate / Prototyping Branch) supports a variety of government managed specialty tactical shelter programs with unique metal fabrication requirements for a variety of DoW customers. One major program is The U.S. Air Force s Deployable Debriefing Facility (DDF) which provides secure, transportable, and mission-ready environments that allow pilots and aircrews to securely review flight data, decompress, and process information immediately after training exercises or real-world combat operations. Other major programs include speciality shelters for the provision of medical care and collective protection from chemical and biological threats. In addition to specialty tactical shelter components, different variants of passageways are also fabricated to complex or connect configurations of specialty shelters in various configurations. Description: DEVCOM SC is in need of custom metal fabrication services based on government provided drawing packages, and is looking to establish a Blanket Purchase Agreement (BPA). The contractor shall provide all management, labor, facilities, equipment, tools, and materials necessary to fabricate, machine, assemble, test, and deliver custom metal components, structural weldments, and sub-assemblies in accordance with government-furnished Technical Data Packages (TDPs), 2D drawings, and 3D CAD models. Example Government TDP: ECU Frame Assembly, 17-3-4850 (Attached). Precision Machining: CNC milling, turning, drilling, and grinding of complex geometries with tolerances up to +/- 0.001 inches on various materials (aluminum, stainless steel, carbon steel, and specialty alloys). Metal Fabrication & Welding: Cutting (laser, waterjet, plasma), bending, forming, and structural welding. Welders must be certified to recognized standards (e.g., AWS D1.1, AWS D1.2, or military equivalents). Surface Finishing: Capability to apply or coordinate post-fabrication finishes such as powder coating, anodizing, plating (e.g., CARC paint, zinc plating), and non-destructive testing (NDI) or inspection. Examples: MIL-DTL-5541 (Chemical Conversion Coating), MIL-T-704 (CARC), T002-WH08 (Powder Coat), TT-C-490 (Zinc Phosphate), ASTM A967 (Stainless Steel Passivation). Quality Assurance: Maintain a robust quality management system compliant with ISO 9001:2015, AS9100, or equivalent military standards. Provide First Article Inspections (FAI) as required. Parts Identified per MIL-STD-130. Government Furnished Property: (Equipment/Materials/Information/ComputerUtilization): The government may provide materials and hardware when commercial sources are not available.
