Hello, I have a little experience with performing commissioning on mechanical and electrical systems in buildings, but never on a LEED project.  I've read that:

"The CxA must have documented commissioning process experience on at least two building projects with a similar scope of work. The experience must extend from early design phase through at least 10 months of occupancy"

Can anyone shed some light on how the process works to "prove" you have the required experience?  What is this "documentation" that is being referred to in the text above?  Thougths?
