I am working on a project that has a two phases of construction. Phase 1 consists of constructing a new building and sitework. Phase 2 involves demolishing an existing building and paving over that space for surface parking lot. Both phase 1 and 2 are scopes of the design team and are on the same overall (continguous) site. Both are within the LEED Project Boundary currently, however, we plan to get the building certified after phase 1 is complete. Phase 2 may or may not be performed by the same contractor. 

How should I best represent this in the LEED submittal? Thank you!
