A project we are working on already has a CxA for the Fundamental Comissioning (Independent consultant contracted by the Owner). Can the CxA for the EAc3 be different from the EAp1 CxA? Can the CxA for EAc3 be a employee/staff of the owner?

Fabiano, I'm not aware of a specific requirement that the CxA be the same for Fundamental and Enhanced, although it seems like there will be unnecessary duplication, and perhaps some confusion. Yes, to your second question.

Tristan is correct of course. If there is already an independent CxA on the project, they would be logical to expand into the Enhanced role, if they have the qualifications you seek for the design review of course. The owner can always be the CxA, again as long as they have the required experience the credit requires.

From the following extract it seems that CxA for EAp1 and EAc3 must be the same. 4.The Same CXA overseeing the enhanced commissioning tasks must also oversee the fundamental commissioning tasks Source : Who Can be the Commissioning Authority http://www.usgbc.org/ShowFile.aspx?DocumentID=1262)

You can have 2. The Enhanced person must oversee, lead and review all Cx efforts. The Enhance person must also be the only one to sign both LEED forms.

While looking to answer another thread, I noticed LI#2496 made on 04/14/2009 that addresses this issue as well, and I think illustrates the issue of multiple CxA firms. This particular LI has three firms involved in a very large project, and USGBC indicates the one hired by the Owner in this case must the ultimate CxA over the other two. Take a look at the new LEED Credit Library on the updated USGBC Website.
