Brookhaven National Laboratory intends to replace its outdated main gate security building with a new modernized entrance portal, including integrated security booths, utilities, security systems, and site improvements. The project will be performed at the Laboratory’s primary entrance, with two prefabricated security booths furnished by the government. A mandatory in-person solicitation overview meeting and site visit are required for all prospective offerors, and failure to attend will make an offeror ineligible for award. The estimated award is September 2026.
