HVAC Contractors Editing and Proofreading Services

A building is handed over with a commissioning certificate. Eighteen months later half the offices are too warm, the plant is running twenty-four hours because somebody could not find the time schedule, and an engineer arrives to investigate. What they need is the record of what was actually set and measured at commissioning. What they usually get is a folder of manufacturer literature and a signed sheet.

We edit what mechanical and HVAC contractors produce — commissioning records and result schedules, pre-commissioning and static completion checklists, air and water balancing records, control strategy and set point schedules, witnessing and demonstration documentation, operation and maintenance manual content, handover and training documentation for building operators, seasonal commissioning and fine-tuning records, defect and performance investigation reports, and method statements for installation and commissioning. Our editors work on the record the next engineer will need.

The commissioning record is the only durable evidence of how a system was set up, and its failure is recording that commissioning happened rather than what it produced. A certificate saying the system was commissioned in accordance with the specification tells a future engineer nothing they can use. We work through these so every measured result is recorded with its design value beside it, since a reading is meaningless without what it was supposed to be and the pair together shows whether the system was accepted on target or on tolerance; so the location of each measurement is identified in terms that will still exist — the terminal reference, the room number, the valve tag — rather than by a position on a drawing that will be superseded; so the conditions at the time are recorded, including whether the building was occupied, the weather, and which plant was running, given that a balance achieved on a mild day with half the floor empty is not a balance; so every set point, time schedule and control parameter is recorded as it was left, because these are what drift and nobody has the original values; so anything that could not be achieved is recorded with what was done instead and who accepted it; and so the operator handover names who was trained, on what, and what they were left to do. Records written this way save the second engineer a week.

Everything you send is treated in confidence, including commissioning data, project records and client information. We are editors rather than mechanical engineers or commissioning specialists, and we offer no view on results, methods or system performance. What we can do is make the record useful to the person who comes next.
