FAQs about EAp1 :

Can the CxA authority be a member of the design or construction team?

What type of certification is the commissioning agent required to have?

The comissioning process turned up a few issues with the commissioned systems that should be corrected. Do we have to correct these issues and include documentation of that as part of our LEED documentation?

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.
