Off-site sorting of the construction waste was used for our project. The hauler/material recovery facility provided project-specific recycling rates for each haul by material type. We were able to track the tonnage diverted by material and the residual material that was landfilled, which is what has been uploaded onto the LEED Online form.
On the form, if I select "commingled" option and then input 100% diverted, the following note comes up in red text: "If 100% of commingled waste is diverted from landfill, select "Diverted" in the "Diverted or Landfill Waste" column." BUT...If I follow the directions of the note, I loose the option of uploading the commingled waste documentation.
Anyone run into this or can provide a suggestion for how to handle the submission?

After scrolling to the bottom of my haul list, I am also getting this note. This leads me to believe that GBCI expects that a "haul" of commingled waste be broken down so that each line item is a constituent part. For example, what could be listed as 10 Tons of 100% Mixed Recyclables would have to be listed as 5 Tons Conc and 5 Tons Steel and that you would be able to check the "x" and upload documentation. Can anyone confirm whether we can just list a 100% diverted dumpster as a single line item (and forgo) documentation if it was all diverted?

I will add the following food for thought - IF you take the templates note Angie and I are getting at face value ("If 100% of commingled waste is diverted from landfill, select "Diverted" in the "Diverted or Landfill Waste" column"), THEN documentation apparently is not required. Otherwise they could have worded the note to instruct you to break it into constiuent parts.

I was approaching the documentation a little differently...In a spreadsheet, I tracked the tons diverted by material type and the tons landfilled. I was using these totals to fill in the form (for example, a line for concrete at 100% diverted). In my head, it seems like a more concise summary and then the tracking spreadsheet, monthly reports and haul tickets provide backup. But not sure if I am totally off-base with what the reviewers are looking for in regards to commingled.

If anyone can verify that the documentation method outlined in the second post on this string has worked, that would be appreciated. Thanks!

Angie,
When the form presents the "commingled" option, my guess is that this is intended for loads where a percentage (say 90%) of the commingled waste is diverted and sent to a recycling facility and the remaining percentage (10%) is sent to a landfill. In your case, it sounds as though 100% of the commingled waste was diverted from a landfill in which case I think you are safe selecting 100% diverted and not worrying too terribly much about whether it was separated on or off site. The way I read it is that they only want the supporting documentation if a portion of the waste was not diverted. With respect to different materials, I would try to list them separately as much as reasonably possible. Two other suggestions: 1) You could always upload the backup documents with the Construction Waste Management Plan as a separate file to cover your bases, 2) Use the "Feedback" button shown in the far right column when you first select the credit from the Scorecard or when you go to the "Credit Information" tab for that credit. Ask your question directly to the source (GBCI/LEED reviewers). They are usually pretty good about responding.
Hope this helps.
