Air-Gapped Analog Monitoring System Installation

A secure, air-gapped analog monitoring system must be installed to track water tank levels and pressure without any digital connectivity, eliminating potential cyber threats. The system must operate entirely through analog means, ensuring no network exposure or remote access capabilities, and must be designed for long-term reliability in the specified location. All components, sensors, and readouts must meet industry standards for durability and accuracy under environmental stressors common to water infrastructure. The work is scoped for performance in Texarkana, Texas, with a compliance deadline of August 11, 2026, and falls under NAICS code 238210 for plumbing, heating, and air-conditioning contracting. This subcontract opportunity is issued by the Department of Justice under the FAO designation, with no set-aside status specified. Respondents are expected to demonstrate expertise in physical security infrastructure, analog instrumentation, and adherence to zero-network-access protocols, with proposals due by the deadline to ensure integration into critical water monitoring systems without compromising operational integrity.
