It's three in the morning, and your hospital's life safety system just put out a fire. Do you know where your sprinkler shutoff is? That's just one example of the questions you can ask to gauge your facility's "vital signs," which in turn lets you better manage the facility as it progresses through its life cycle. The emphasis is on an accurate and updated vision of the facility, down to air handler function, maintenance, and document integration. The results could help you avoid a flood of problems that otherwise may be a heartbeat away. By Mark R. Handy, AIA
