Under v3, if a project wanted to pursue the enhanced Cx credit, a third-party CxA was required, and that entity completed the activities for both the prerequisite and the enhanced credit.
Have the requirements for v4 changed any? We have a client asking if they can do the activities associated with the prerequisite in-house, and hire a thrid party to do the enhanced items.
Thoughts?

The qualifications for fundamental and enhanced commissioning in v4 are largely unchanged from v2009 (v3). One recent LI was issued that allows enhanced commissioning agents to be contracted under single contracts to a PM or GC with specific reporting requirements, and that has been incorporated into v4.
You need to review the scope of fundamental and enhanced carefully. The scope of fundamental has expanded significantly, and therefore enhanced has contracted. I was and continue to be fairly critical of some of these changes. Some of the scope expansions (like envelope being part of the OPR and BOD) are very good, I just do not like where they placed them on the process.
The ability to have two firms doing commissioning is feasible under v4 in my opinion. The enhanced firm has to be in overall control of the process, and would be the lead even if you perform some of the tasks. You should consider including envelope commissioning, as that is now part of both fundamental and enhanced.
Bottom line, the firms that can perform the two levels of commissioning is largely unchanged, the scope has changed with some enhanced tasks moving to fundamental, and there has been some scope added as well. There is significantly less track record to know how this affects the work at this point.
