The City of Plymouth approved a $17,200 sole‑source contract with Automated Energy Systems to replace obsolete Flex I/O modules and install new Tridium I/O modules for the city’s arena dehumidification system. The work includes removal of existing hardware, installation of Tridium IO‑R‑34 and IO‑R‑16 modules, wiring to a Phoenix Contact JACE controller, programming the controller for dehumidification control, updating graphics and documentation, and performing start‑up testing. This upgrade modernizes the building‑automation platform, improves reliability, and ensures compliance with current control standards.

• Funding: $17,200 drawn from the Recreation Capital Improvement Fund (account 408‑900‑976.751).
• Procurement: sole‑source justification based on AES’s prior installation (2020) and unique technical expertise; no competitive bidding required.
