I'm working on behalf of a GC on a complicated historic renovation and new construction project that's being done in several phases with separate contracts between Owner and GC. The project was registered with LEED NC 2009 during the 1st phase (but after the 1st phase started) so the C&D Waste was not properly documented at the beginning of the 1st phase and the LEED goals were never communicated to the GC until the end of the 1st phase, so C&D Waste Recycling rate will be VERY low. Now the design team has identified the C&D Waste Recycling Credit, 50% as one of the credits the GC needs to pursue. So it'll be complicated to calculate and also unclear as to whether or not waste from the 1st phase of work will need to be included in the C&D Waste Recycling Calcs for the main project contract which is Phase II and will start well after the project registration under v 2009. Any thoughts?
Also, the documentation of what was removed to be reused and what was repaired in situ is also also not properly documented and will be very messy to try & piece together at this point. So this is another issue (The original bldg. dates back to 1823 and much of what was supposed to be reused couldn't due to age/service life of materials.) But I feel that the project should get BOTH of the Bldg Reuse credits just based on the fact that the owner is trying to preserve the bldg. in tact as much as possible and is making repairs to preserve the remaining life of the bldg. Any ideas on this as well is greatly appreciated.

Hi Debra, Thank you for your questions. This does sound like a complicated project and I understand your concern regarding achievement of both of these credits.
Although I could provide you with guidance on C&D questions, I would recommend that you post your first question to the MRc2 page as those are the official LEEDuser experts that should address and provide guidance.
As for your second question, I'm happy to help provide some general guidance. It comes down to taking an inventory of surface area SF of floors, roof, exterior wall (i.e. envelop) and making a note of what was existing (reused/remained) and what needed to be replaced. It does not need to be over complicated and can be tracked through an Excel spreadsheet calculation. If you have a Revit model to get quantities and areas, this is easiest. If you don't have access to a Revit/CAD model, then doing area take-off's from PDF sheets will work with a scale. My recommendation is to try and keep it simple, straight forward.
