This is a Questions and Answers document (Round 3) dated February 21, 2025, for Request for Quote #446572 regarding a Liquid He Dewar and Sub-Cooler procurement for Brookhaven National Laboratory.
The document addresses two technical clarifications: 1) The ladder and platform material requirements, confirming that painted carbon steel is acceptable in white, light grey, or dull green colors, with aluminum being an alternative option that must be specified in quotes; 2) A clarification regarding ASME U-stamp requirements, confirming that the ASME-U stamp is NOT required on the Vacuum Vessel, which resolves a discrepancy between specification SPEC-CAD_1365 section 3.12 and drawing #CA6000026.
