The process our firm has used with success to troubleshoot and find solutions is typically kicked off with a walk-through, where we meet with facility operators and end users to find out what their experiences have been and what they feel is underperforming or not working correctly. Normally during this walkthrough, project scope can be further defined and expectations can be clearly stated. At the project walk through, we like reviewing all drawings and past testing reports when they are available. Drawing review is critical for understanding the objective of the original design and the performance expectations for the equipment. Any existing testing reports will provide baseline information that can be used to compare to new readings.
