Statement of Work (SOW) / Performance Work Statement (PWS)

This Statement of Work (SOW) outlines the requirements for the procurement of sixteen (16) charge readout plane support superstructures (CRP-SSTs) for the Deep Underground Neutrino Experiment (DUNE) Vertical Drift (VD) detector. The document details the contractor's responsibilities for designing, manufacturing, inspecting, testing, and delivering these critical structural components.

• Design and Engineering: Develop engineering packages for both large and small SST frames, including 3D models, fabrication drawings, and structural engineering calculations (FEA). This involves iterative review and approval by Brookhaven Science Associates (BSA).

• Fabrication: Manufacture SST frames (four small, twelve large, with options for additional units) adhering to strict tolerances and material compatibility requirements (liquid Argon cryogenic environment).

• Testing: Conduct Factory Acceptance Testing (FAT) for both large and small SST first articles, including dimensional verification, test assembly, and survey. BSA delegates will participate in these processes.

• Documentation: Provide comprehensive end-item documentation packages for each shipment, including inspection reports, material certifications, and as-built configurations. All documentation requires BSA approval prior to shipment.

• Packaging and Delivery: Design and fabricate protective packaging for shipment. Delivery locations include CERN for the first article large SST and the Far Detector & Cryogenics (FDC) South Dakota Warehouse Facility (SDWF) for other frames.

• Quality Assurance: Maintain a documented quality assurance system meeting applicable national standards (e.g., ISO 9001). Welding programs must meet applicable standards (e.g., ASME, AWS).

• Tolerances: Contractor-generated fabrication drawings must meet or exceed tolerances specified in bid technical specification drawings.

• Material Traceability: Materials must be identified and traceable to their lot and/or heat numbers.

• Non-conformance: Implement a failure reporting, analysis, and corrective action system. All rework and repairs require BSA approval.

• The SOW specifies delivery timelines relative to order receipt, BSA approval, and shipment of first articles. Specific contract dates will govern.

• Delivery locations include CERN (Switzerland) and the FDC SDWF (Rapid City, SD).

• Material Compatibility: All materials must be compatible with a liquid Argon cryogenic environment.

• Fasteners: Specific requirements for stainless steel and silver-plated hex nuts.

• Quality Control: BSA representatives will have access to the contractor's facility during agreed-upon processes.

• Communication: Frequent update meetings are required during the engineering phase. Timely updates on design, procurement, fabrication, and delivery status are mandatory.
