Data Center CxA

Peter, A couple of things should be clarified before getting to an answer. I'll assume the project in question is just the data center and that the 600 kW system is dedicated to that data center. Given that, is the project pursuing the Enhanced Commissioning credit or just the prerequisite? If Enhanced, then v4 is clear in that the CxA cannot be an employee nor a subcontractor of the design or construction firms. If Fundamental, then a qualified individual employed by the project's design or construction firms may be considered to lead the commissioning process if that project is below the 600 kW or 175 kW thresholds stipulated by v4. Since the project in question exceeds 600 kW capacity, a CxA for this project cannot be an individual employed by the design or construction firms. One additional point: Even if the project is below the outlined thresholds and only pursuing the Fundamental prerequisite, v4 clearly states that in these cases, the CxA should be a QUALIFIED employee of the design or construction firms. That means that the employee designated as CxA shall have experience on at least two projects with similar scope (space use, systems, operations, size...) and that that experience extends from the projects' early design phases through occupancy. So the short answer here is that you cannot act as the CxA for the project you described, based on not meeting the defined threshold. Your company should hire a qualified, third-party commissioning agent in order to bring the greatest value to the project.

Agree with Paul. This language is very typical of standards and codes in describing an exception to the requirement so will only state the condition upon which the exception can be applied. Data Centers and complexity is not based solely on SF but on density, hence the different metric used.

Peter, I went back to the guide based on your question related to fundamental only and I agree that for that service only, the CxA can be an "employee of the design or construction firm who is not part of the project's design or construction team..." The on-line guide is a little clearer as it states this for all fundamental services, then goes on to list the exceptions when the design team member can also be the CxA. Enhanced in v4 immediately means independent.
