About this opportunity
The Department of Energy Office of Science, through Brookhaven National Laboratory, is seeking contractors to fabricate and polish two SI Plane Mirrors with highly specific technical requirements. The mirrors must be manufactured to precise dimensions of 508.5mm x 38.1mm x 9mm with stringent tolerances, as-polished slope errors of 5μm, and no coating applied. Offerors must demonstrate past experience by providing at least one project example of producing mirrors of equal or larger size with similar specifications within the last five years. The procurement will be awarded on a firm fixed price basis to the responsive and responsible offeror submitting the lowest total price while meeting all technical requirements. The original quote submission deadline was September 24, 2025, though an amendment has been issued providing questions and answers while closing the Q&A session, and vendors must be registered in the System for Award Management (SAM).
This procurement does not utilize any set-aside designations and falls under NAICS code 327215 (Glass Product Manufacturing) with a size standard of 1000 employees to determine small versus large business classification. No incumbent contractors or potential award values are specified in the available documentation. The contract requires delivery of exactly two mirrors with an anticipated timeline of no later than 8 weeks after contract award, though the draft purchase order suggests a 9-week performance period. Payment terms are structured as Net 10 days for small businesses and Net 30 days for large businesses. An amendment has clarified that the government declined a vendor's proposal to increase mirror thickness from 9mm to 30mm, maintaining that the original specifications have proven operationally effective in previous procurements.
