I wanted to clarify something that I recently heard from a contractor on a LEED project. 

For a number of the MR credits the receipts are required for the project. Typically, we collect ALL the receipts from the project duration. However, we were recently told that on other LEED projects the team has instead provided the AIA summaries for all vendors and then just the required receipts for 20% of the project sum. 

Could someone please clarify whether or not this is acceptable? It would obviously be much easier.
