NC-v4 EAp1: Fundamental commissioning and verification
In LEED v4, the CxA for Enhanced Commissioning must be independent of the design and construction team- but what if the construction team is also the owner, as in design-build?

For a building with individual systems per unit, does every single system need to be commissioned?
What kinds of projects must the CxA demonstrate experience on?
What level of authority does the CxA have towards correcting inaccurate or erroneous construction?
Can the CxA be a member of the design or construction team?

The CxA may be a qualified employee of the owner, an independent consultant, or an employee of the design or construction firm who is not part of the project’s design or construction team, or a disinterested subcontractor
of the design or construction team. In your case, I consider that assigning the Fundamental Commissioning tasks to an employee of the construction firm who is NOT part of the overall project's team would be ok.

Yes, if the construction firm is the owner, then the CxA can come from that organization. The ownership should be confirmed by contract. If it is a DB contract that is build-to-suit and ownership changes at the end of construction, then it is not as clear that they are truly the owner. If they are developing the project and then will operate the building with multiple tenants, then they would be the owner for sure. There are some contracts where the GSA is the only occupant but it is a long term lease back to a contractor/owner/developer. In this case, and this is really my opinion, the contractor can hold the contract for the CxA, but that CxA should be an independent firm.
