Construction Waste Management Core and Shell and Tenant Upfit Spaces

I'm not aware of rules on this or rulings, but it feels like a judgement call, and one you could justify. Directionally speaking, you're taking on more responsibility, not less. And you're not overlapping with other LEED projects, so you're avoiding double-counting. I assume it might be more work to separate, so I'm thinking you can make a note in the narrative about the scope of debris that was included, that it was impractical to separate, and that this met and exceeded the credit intent.

I agree with Tristan and do believe that justification could be made if it is impractical to separate.  I am curious, however, if there are two separate contracts with the hauler and if the tenant is paying for their own hauling services for construction of their space?  If that is the case, it could be simple to keep them separate.  There was a CIR previously (ID# 2220) from 2008, which I know is a while ago, but has some insight that might be applicable here.  It referenced a LEED-ND project wanting to document construction waste on a "neighborhood-wide" basis for pursuit of two separate LEED buildings within the LEED-ND.  The ruling identified that it was not acceptable to do a "neighborhood-wide" method because both buildings needed to be accountable for their construction waste practices and be able to note separate diversion rates.  Granted the two buildings in question were both pursuing certification, which is why I believe it required to keep them separate.  While your tenant space is not pursuing a CI certification, which maybe is the way it can work to include waste for both the CS and tenant space, I do think that it is important to ensure that both the CS and the tenant space have a well written plan for the construction waste that each respective space is producing and to have them both be accountable for waste diversion efforts.  Having accountability for the tenant space can also contribute to the detail included in your Tenant Design and Construction Guidelines, if you are pursuing that particular credit.
