Am I right in understanding that for Enhanced Commissioing only the following may subcontract the CxA:

- Engineer or Architect (designer)
- Owner

What about Project Manager firm? What if the Project Manager Firm hires the General Contractor on behalf of the owner, can the PM firm still hire the CxA or do they hold construction contracts. They are not actively involved in construction or design, but responsible in a sense for both. Any others?

What if the PM firm does not hire a GC, but several Contractors or General Contractors...does this make the PM firm a General Contractor themselves? What if they also hire the Design Team?
