Industrial Control System (ICS) Modernization – PLC & HMI Replacement

The contract calls for the complete replacement of an existing legacy programmable logic controller (PLC) system with a modern industrial automation platform designed to enhance operational efficiency and reliability. The project includes the installation of a touchscreen human-machine interface (HMI) to provide intuitive real-time monitoring and control, alongside a hardwired manual backup panel to ensure continuous operation during system failures or maintenance. A core requirement is zero downtime during the transition, necessitating meticulous planning, phased implementation, and redundant safety measures to maintain uninterrupted industrial processes throughout the upgrade. All work must be conducted in strict compliance with industrial automation standards and integrated seamlessly with existing infrastructure. This subcontract is issued under the NAICS code 238210 for Electrical Contractors and Related Work and is associated with the Department of Defense through its agency, W2SD Endist New England. The place of performance is located in Stamford, with proposals required by August 14, 2026. The project emphasizes precision timing, system interoperability, and fail-safe design, demanding vendors to demonstrate proven expertise in industrial control system modernization, particularly in environments requiring continuous operation without disruption. Successful bidders will be expected to deliver not only hardware and software components but also comprehensive training, documentation, and support to ensure long-term system stability and operator proficiency.
