How Dartmouth College Automated OT Maintenance with an IT-Driven Tech Stack
In this presentation from the January 2026 NexusCast, Douglas Plumley, Software Architect at Dartmouth College, and Andrew Rodgers, Co-Founder of ACE IoT Solutions, dive into step five of the OT device management strategy: maintenance. Managing a 6.6 million square foot Ivy League campus plus a separate real estate portfolio, the Plumley and Rodgers address the impossibility of manually keeping records current for thousands of static and shifting cyber-physical systems. They reveal how Dartmouth stopped failed integrations and certificate of occupancy delays by treating OT assets with the same automation and rigor as a high-performing IT department. The session details how they connected sources of truth directly to stakeholders, ensuring that when an operational issue strikes, the team isn't burning time chasing devices that no longer exist.
Nexus Pro members will get an exclusive look at the specific IT-stack used to maintain compliance, including the development of the Grasshopper platform from ACE IoT to fill visibility gaps that even mature IT tools missed. Plumley explains how they use network monitoring tools like Akips and Infoblox to map MAC addresses to switch ports, alongside open-source Python scripts to hunt down specific vulnerable firmware versions across the network. You will see real-world results, including a lighting integration fix that dropped energy costs by over $10,000 per year, and learn about the "Integrated Automation Program" that connects campus services with technology teams. This recording is essential for any leader who wants to stop "throwing hardware at problems" and start managing building technology at enterprise scale.
