472077 RFP - dune VD CRP-SST

Brookhaven Science Associates (BSA), operating Brookhaven National Laboratory under a Department of Energy Office of Science contract, is soliciting proposals for the fabrication of sixteen (16) Charge Readout Plane Support Superstructures (CRP-SSTs) for the Deep Underground Neutrino Experiment (DUNE) Vertical Drift detector. The procurement falls under NAICS code 332312 (Fabricated Structural Metal Manufacturing) with a 500-employee small business size threshold and is posted for full and open competition. Contractors must demonstrate fabricability and construction methodology, propose effective connection methods for large subassemblies with tolerance improvements, provide prior experience with comparable welded stainless steel structures, document fabrication capabilities, and maintain ISO 9001–compliant or equivalent quality assurance programs. Evaluation will employ a Best Value methodology with technical factors weighted more heavily than price, allocating 100 total points across five scored categories: Fabricability and Construction Methodology (20 points), Connection Methods for Large Subassemblies (15 points), Prior Experience and Past Performance (30 points), Fabrication Capabilities (25 points), and Quality Assurance/Quality Control (10 points), with offerors required to achieve a minimum of 65 percent of available technical points to be considered responsive. The deadline for submitting questions is March 23, 2026, with proposals due by April 10, 2026, and an estimated award date of July/August 2026.

This procurement involves no set-aside designations and has no identified incumbent contractor. The contract value is to be determined based on submitted proposals, with delivery structured on a milestone-based payment schedule extending through the target completion date of September 2, 2027. The requirement consists of four small frames (approximately 450 kg each) and twelve large frames (approximately 2,000 kg each), with optional quantities of up to two additional frames of each type plus cleaning/degreasing services. The large SST frames will be designed as three subassemblies to accommodate underground conveyance constraints, and the contractor must deliver engineering packages, first-article test assemblies, and complete serial production within approximately forty-eight weeks of technical performance approval. Place of performance includes the Far Detector & Cryogenics South Dakota Warehouse Facility in Rapid City, South Dakota for domestic shipments, and CERN in Switzerland for international deliveries, with all material deliverables subject to Buy American Act compliance and comprehensive quality assurance requirements including factory acceptance testing and detailed documentation packages.
