Quick question, can the contractor of building's BAS (for both the installation and manufacturer of DDC/control components) be designated to be the CxA?

No, the BAS contractor should not be the CxA. Our experiance has been that many of the corrective actions required are related to the DDC system and programming, so having the BAS contractor in this role would not provide any oversite or quality assurance.

I agree. We have found that most of the corrective measures are DDC related. It seems that the controls contractor rarely gets the bugs out before commissioning even if they say they have.
