Common dumpsters for overlapping CS and CI projects- same GC

We took the total amount of the waste stream for the entire retail re-development project and attributed a % to our LEED supermarket project based upon our building and site areas relative to the whole development which consisted of 800,000 sf of retail on a 62-acre site. I am not sure if that translates to your situation. Depending on the project, core and shell materials can be greater in quantity and/or weight than those of a CI project, but that varies with scope of course.

Kathy, have you received credit for your projects yet? I also have a CS and a CI project within the same building with overlapping time schedules. I might even have two CI projects in the building before we’re done. How can I separate the waste? There is no way to have different dumpsters for different projects (and make construction workers separate CS and CI waste!). Can I make a reasonable assumption and argument on how much waste that comes from each project? Our company’s goal is to keep 95 % of waste out of landfill, both CS and CI. Anyone else have experience?
