Forward Hadronic Calorimeter Absorber Structures

The solicitation for the manufacturing and testing of longitudinally segmented forward hadronic calorimeter (LFHCAL) steel absorber modules is issued by Brookhaven National Laboratory under contract number MB457842, with a response deadline of August 10, 2026. This opportunity is reserved exclusively for Women-Owned Small Businesses, and the NAICS code 332999 indicates it pertains to other fabricated metal product manufacturing. The work involves producing precision absorber modules for the Electron-Ion Collider’s General Purpose detector, with technical requirements defined in the Statement of Work (Revision 5 dated January 9, 2026), the technical specification EIC-DET-SPC-021, and supporting engineering drawings EPC-FWD-HCL-DET-ASM-100 and EPC-FWD-HCL-DET-ASM-200. Key material specifications mandate the use of AISI 1020 magnetic carbon steel and stainless steel components, with strict adherence to welding procedures including electron beam welding, post-weld machining, and nickel plating, all in compliance with AWS D1.1 standards. Quality assurance is governed by BNL-QA-101 requirements, encompassing supplier quality systems, counterfeit parts prevention, calibration of test equipment, and electrostatic discharge controls. Proposals must include completed AMS Form 050 for representations and certifications, and a detailed pricing sheet (AMS-Form-043) with firm prices valid for 120 days under FOB Destination terms and Net 10-day payment conditions. The contract is firm fixed price, with a base award and two optional periods for additional modules. Deliverables include program and test plans, manufacturing documentation, and the physical units, with final delivery designated to Oak Ridge National Laboratory by U.S. citizen drivers. All proposals must adhere strictly to revised documentation issued through Amended 3 on July 10, 2026, which superseded prior revisions, and all inquiries must be submitted in writing to the designated Contract Specialist. Noncompliance with submission protocols or failure to incorporate the latest revisions will result in proposal rejection.
