Day in the life
A Day in the Life of a Stationary Engineer
What stationary engineers actually do from the start of a shift to the end: the tasks, tools, schedule and realities of the job.
Check boiler pressures and log readings. From there, the day usually includes operate boilers, chillers and pumps, monitor building automation systems, and perform preventive maintenance. Many facilities run 24/7, so shift work, weekends and on-call duty are common.
