Commissioning firm instead of a specific person?

Hi Veronika, I think it will be ok if the person representing the Cx firm will be also responsible for all the Cx process. According to LEED Interpretation Ruling 10/24/2008 ID# 2340: "...one party (the independent Commissioning Authority) must lead and oversee all commissioning efforts relating to both fundamental and enhanced commissioning. While this does allow for some limited division of the tasks required by this credit, there must be one independent Commissioning Authority leading and overseeing all LEED commissioning efforts... ...Further, it is required that the independent Commissioning Authority perform EA Credit 3 tasks 2, 3, and 6. Beyond these restrictions, it is the responsibility of the independent Commissioning Authority to determine who shall perform each of the remaining tasks under both fundamental and enhanced commissioning." According to LEED Interpretation Ruling 9/10/2007 ID# 5080: "...the independent CxA need not always formally review and approve each deliverable. However, it will be the responsibility of the independent CxA to determine the roles and responsibilities pertinent to each of the required tasks under both EA Prerequisite 1 and EA Credit 3. Note that the CxA individual must themselves do EA Credit 3 tasks 2, 3, & 6." Hope that helps!
