Many buildings survive or succumb to incidents not because systems are complex, but because a simple replacement part is missing. In this episode Alex Morgan talks with Michael Harrington about building a pragmatic spare-parts strategy for critical low-voltage, power, and connectivity systems. We focus on realistic, owner-friendly practices: what items to prioritize, how to balance cost versus risk, how to avoid obsolescence, and workflows that turn an attic shelf into a reliable resilience buffer. Using concrete examples from commercial property operations, Michael explains decisions that cut mean-time-to-repair and protect tenant operations without overstocking. Listeners will walk away with a short checklist and clear rules-of-thumb to start a spares program that actually gets used—plus governance tips so spares don’t become forgotten liabilities.
