The FBOP anticipates a firm-fixed-price construction contract to replace the campus-wide medium-temperature hot water distribution network at FCC Allenwood, located on Route 15, two miles north of Allenwood, PA 17810. Work includes excavation and installation of new underground pre-insulated piping, mechanical room connections, heating hot water pumps, domestic hot water heat exchangers, building entrance valve stations, controls, and boiler plant upgrades. The contractor must provide temporary heating, perform selective demolition and surface restoration, coordinate utility interruptions with prison staff, and work inside an operating correctional facility under security, quality control, commissioning, testing/balancing, training, and closeout requirements. This is a Sources Sought Notice for market research only, not a solicitation; capable prime contractors are asked to register/respond via SAM.gov and may complete a market research questionnaire. A future solicitation, if issued, will be posted later and will require active SAM.gov registration and MPIN-based access to controlled documents.
