BMS commissioning experience: what to verify

Ask for the platform, controller families and building systems involved. Then establish whether the candidate programmed, configured graphics, integrated equipment, checked points, tested sequences or witnessed another party's work.

A software name is useful context, but it does not describe the depth of responsibility. Mechanical plant knowledge and the ability to interpret an approved sequence should be assessed separately from familiarity with a user interface.

Ask the engineer to explain how they established that a field condition, its displayed value and its effect on the control sequence agreed with the approved documents.

ASHRAE emphasizes early completion of controls and measurement systems to support troubleshooting and operational baselines. Ask whether the candidate's work produced usable trends and event records, not merely a set of closed checkout tasks.

For a role with independent witness duties, clarify how independence and access are managed. The person who can change code is not necessarily the person authorized to accept the resulting system.
