Drawings and Specifications-DUNE_Flange_STEP Files.zip

This file is a collection of STEP (CAD) format technical drawings and specifications for a Deep Underground Neutrino Experiment (DUNE) Cold Electronics (CE) Flange component. The file was added as an amendment to RFQ 476754 on May 1, 2026, to provide vendors with three-dimensional parametric models in addition to the original two-dimensional drawings and specifications previously included in the solicitation.

The STEP files serve as supplementary technical documentation to support the RFQ 476754 for the DUNE CE Flange procurement. These files enable potential vendors to access detailed component geometry, dimensions, and design specifications in a standardized CAD format compatible with most engineering software platforms. The amendment clarifies that no new questions regarding the RFQ will be accepted past the original question due date of April 29, 2026, and vendors are directed to reference the primary RFQ documentation and contact Shaylyn Price at sprice@bnl.gov for any inquiries. This solicitation is issued by Brookhaven Science Associates, LLC, as the operator of Brookhaven National Laboratory under a Department of Energy contract.
