The Brookhaven Science Associates (BSA) seeks a qualified contractor to design, fabricate, and install highâresolution diffraction (HRD) radiationâshield enclosures for the NSLSâII beamline at Brookhaven National Laboratory. The scope includes full engineering design meeting stringent synchrotron radiation leakage requirements, detailed drawings certified by a New York Stateâregistered PE, manufacturing of leadâsteel composite panels, onâsite installation, safety and quality assurance programs, and a fiveâyear warranty. Proposals must include technical and price volumes, demonstrate prior experience with similar radiation shielding projects, outline manufacturing and installation plans, and comply with DOE and BSA procurement rules. Evaluation will be bestâvalue, weighting technical capability (70 pts) over price. ⢠Design and engineering of shielded enclosures (doors, walls, ceiling, labyrinths, seals). ⢠Fabrication of leadâsteel composite panels, lead containment, and durability measures. ⢠Onâsite installation, alignment with NSLSâII storage ring, and testing for radiation leakage. ⢠Comprehensive safety, health, and qualityâassurance plans. ⢠Required pastâperformance references, financial capability, and SAM registration.
