Dual PLC System Replacement and Programming

The contract demands the complete replacement and reprogramming of dual redundant programmable logic controllers (PLCs) installed in critical power and switchgear systems, ensuring uninterrupted operation and enhanced reliability. This scope includes the full lifecycle of logic development, system integration, simulation testing, and live-bus commissioning to validate performance under real-world conditions without disrupting ongoing operations. The work must adhere to stringent redundancy standards, where both PLC units operate in parallel with automatic failover capability to maintain system integrity during maintenance or failure events. All programming and configuration must be thoroughly documented and validated through simulated scenarios prior to deployment on live infrastructure. The project is classified as a subcontract under NAICS code 238210, indicating it involves electrical and related construction services, and is being procured by the Department of Defense under the office designation FA4600 55 Cons Pkp. The solicitation was posted on August 7, 2026, with a firm response deadline of August 24, 2026, at 5:00 PM.
