Commissioning is NOT Functional Testing!

Now let me back up a little to explain myself. Recently I had received a few construction schedules for review and at the end of the schedules was a time block just before substantial completion titled: “Commissioning”. Commissioning is not one line item activity, it is a process throughout the project (design, construction and post construction stages) with many activities. Typically when we see the line item of “Commissioning”, we understand it was in reference to the functional performance testing stage – an important stage where systems are determined accepted or not and when the functionality of systems is verified.

But before the functional performance testing stage, many commissioning activities have to be completed successfully. We need to make sure systems are installed, tested, operated and verified before proceeding to functional performance testing.

Now to keep this post short and to the point, commissioning activities to be included in construction schedules to assist with keeping the project on track should include:

  • Equipment startup
  • Controls point to point testing
  • Controls system sequence of operation reviews
  • Air and water balancing
  • System functional testing
  • O&M training

Let’s get those construction schedules in check, and remember if you have any questions on commissioning activities to be included in the construction schedule, ask your commissioning provider! I am sure they would be more than happy to help.
