The formal solicitation will be issued at a later date and will also be posted on SAM.gov at that time. Note that switchgear and transformers are being provided to the contractor as Government Furnished Equipment (GFE). Interested contractors are invited to submit a statement of interest along with a capabilities statement to BSA's Contract Specialist, Megan Howard, at mhoward@bnl.gov. Please include your Sam.gov Unique Entity Identifier (UEI). Project Description: The Physics Building was constructed in 1962 and much of the electrical system, original to the building, is beyond its useful life. These systems are also not compliant with current building codes, contain hazardous materials and need complete upgrades. The existing protective devices may not operate as specified, increasing the potential for arc-flash hazards and system damaging electrical faults. Repairs are cost prohibitive and may lead to extended unplanned outages in this mission critical facility. The Contractor shall provide all labor, supervision, materials (except as noted below), equipment, and services necessary for complete removal and upgrading of the existing Building 510 electrical substation equipment that feeds the newly replaced electrical distribution switchgear. This project includes the removal of two medium voltage substation transformers, one medium voltage oil switch and medium voltage distribution cabling. The project also includes the installation of a new exterior substation with two new medium voltage transformers, one pad mounted medium voltage switchgear and medium voltage feeders in a new concrete encased duct bank. The new substation will be constructed in the north-loading dock parking lot, complete with new transformer and switchgear pads, grounding and crushed stone. Long lead electrical equipment procurements are planned early in the project and construction of the substation infrastructure can be completed in parallel. Once the cutovers are completed the old transformers and oil switch will be removed from the equipment vault in the basement of Building 510. The Contractor shall not procure the switchgear or transformers under this contract. Installation will be executed in a phased approach in order to minimize electric service disruptions to the building and will provide provisions for future redundant circuit configuration. ## Open now in the same industry 38 open in NAICS 238210. - 106 CE ELECTRICAL LOOP REPAIR (W50S8E27QA001), due November 6, 2026 at 10:00 AM EST. https://abierto.us/opportunities/w50s8e27qa001 - Brooklyn Upgrade Life Safety/Critical Branch Electrical Distribution Construction (36C77626B0020), due November 24, 2026 at 3:00 PM EST. https://abierto.us/opportunities/36c77626b0020 - Project620-22-110 Replace and Upgrade Fire alarm System at Montrose VAMC (36C24227B0009), due December 16, 2026 at 10:00 AM EST. https://abierto.us/opportunities/36c24227b0009 ## Publications - October 12, 2026: Sources sought, due October 23, 2026 at 4:00 PM EDT.
