Amendment 1 to RFP-LBNF-372669-JD, titled "LAr Circulation," provides instructions for accessing a large STP file that could not be hosted on SAM.gov. Due to file size limitations, the document directs users to download the STP file for "Amendment 1 STP File LAr Circulation" from a designated Fermilab OneDrive portal. This amendment is crucial for parties interested in the LAr Circulation RFP, as it provides essential supplementary materials for the solicitation.

This government file, "LAR CIRCULATION PUMPS SYSTEM VD PIPING & INSTRUMENTATION DIAGRAM," from Fermi National Accelerator Laboratory, is a detailed piping and instrumentation diagram (P&ID) outlining the design and components of a liquid argon (LAr) circulation pump system. The document, intended for reference and review, includes specifications for various valves (HV, SV, PSV, FCV, PV), pressure and temperature sensors (PT, TE, PI, PDT), flow sensors (FT), and associated cryostat-turbine pumps. It details connections for gas vent, common vent header, LAr from condenser pumps, LAr/gas to condenser pumps, and purge distribution piping. The diagram is crucial for understanding the system’s layout, control mechanisms, and safety features, indicating its relevance for federal projects involving large-scale cryogenic systems and particle physics research at institutions like Fermilab.

Amendment No. 1 to Solicitation No. RFP LBNF-372669-JD, issued on November 26, 2025, extends the proposal due date for the LONG-BASELINE NEUTRINO FACILITY LAR CIRCULATION project to January 5, 2026, at 5:00 P.M. CST. It also extends the deadline for technical questions to December 8, 2025. The amendment addresses several vendor questions, clarifying that the project is a design-build situation and providing a .stp file for the valve box for reference. It confirms the un-insulated piping is within the offeror's design scope and includes a P&ID to define in/out-of-scope tie points. Additionally, it clarifies that the VD and HD cryostats will be identical, each requiring three valve boxes. Offerors must acknowledge this amendment via SARC, fax, letter, or email.

Dispute resolution, applicable laws (Illinois law where federal law is absent), information release, and notification requirements are also specified. Crucially, it incorporates numerous Federal Acquisition Regulation (FAR) and Department of Energy Acquisition Regulation (DEAR) clauses by reference, with specific applicability thresholds for subcontract value, ensuring compliance with federal government flow-down provisions for supplies.

The LBNF/DUNE-US LAr Circulation J-13 Project Schedule outlines administrative and procedural requirements for documenting engineering, manufacturing, and testing progress for the Long-Baseline Neutrino Facility (LBNF) / Deep Underground Neutrino Experiment (DUNE) – US project. This document, relevant to federal government RFPs and grants, details project scheduling, including administrative requirements, progress reporting, resource management, and coordination among subcontractors. It specifies the use of Critical Path Method (CPM) schedules, Primavera (P6) software, and earned value tracking to monitor progress. The scope covers eleven Argon Cryogenic Packages for cryostats VD and HD. Key aspects include detailed engineering and manufacturing phase schedules, monthly updates, reporting of unusual events, and specific qualifications for schedulers. The document emphasizes adherence to a strict schedule, with provisions for recovery schedules if progress falls behind, and mandates coordination with FermiForward for all project milestones and modifications.

This government file details the interface specifications and installation requirements for a Barber-Nichols (BNCP-76-998) pump, likely for a Liquid Argon exterior application. The document provides crucial dimensions in both inches and millimeters, outlining the pump's physical layout, including inlet and discharge diameters, and connection types like the 3/4" NPT motor junction box. It specifies installation considerations such as allowable tubing loads (50 LBF in X,Y,Z and 5 FT-LBS in X,Y,Z), recommended pipe lengths before elbows (5-10 diameters for inlet, 2-3 for discharge), and the pump's required vertical orientation. Critical warnings include not obstructing the motor's fan-cooled area and the necessity of customer-supplied pump mounting plates and seal welds. The document also includes details on weld specifications, material requirements (304/L or 316/L SS for weld-in housing), and the use of hoist rings for lifting. It is a technical drawing providing essential data for integrating the pump into a larger system, indicating the precision required for federal, state, and local RFP projects involving specialized equipment.

This document outlines the Scope of Work for the Liquid Argon (LAr) Circulation System Vertical Drift (VD) and Horizontal Drift (HD) Equipment for the Long-Baseline Neutrino Facility (LBNF)/Deep Underground Neutrino Experiment (DUNE)-US project. The project involves the detailed engineering, manufacturing, procurement, and testing of Vacuum Jacketed Pump Valve Boxes, associated piping, valves, instrumentation, and cryogenic protection equipment. The system is responsible for transferring liquid argon to and from the LAr Purification system, with each cryostat (VD and HD) requiring three pump valve boxes. The document details extensive engineering, functional, mechanical, manufacturing, and safety requirements, adhering to numerous American and International codes and standards. It also specifies detailed requirements for valves, pressure safety devices, temperature and pressure sensors, and materials, ensuring a 30-year operational lifetime and safety within the detector cavern environment. The supply also includes cryogenic equipment protection such as ladders, modular platforms, and support beams.
