MRc2 Construction Waste Management

Michael - My apologies for not getting back to you sooner. I was on business travel. 

Can you please tell me what form version you are using? (You can get this information from the lower right corner.) I haven't run across this problem but I haven't used the v06 version of the CI form. I attempted to recreate your situation but am not sure I have enough information to do so. But there could be a problem with the form. Please let me know the form version so we can report a problem to USGBC if needed.

In the meantime, if you are ready to submit your project, you could skip the Table: Construction Waste Diversion table and use Special Circumstances. Note the problem in the Special Circumstances text box and then upload a cleaned up, easy to interpret version of your spreadsheet. Provide the required backup for commingled under that upload.

Regarding your last question, my answer is No. I have always combined my waste data by material by vendor for the entire project and have never input it by month.

Michael - Thanks! Here are a couple of thoughts:

• If you pick 100% for "Commingled" the calculation is skewed. Per the instructions "If 100% of commingled waste is diverted from landfill, select "Diverted" in the "Disposal Method" column." Did you do that? Note: I would use the Special Circumstances of the form to explain why you did this for commingled collection.
• I wasn't able to recreate the problem that you described because I couldn't quite follow it. But could it be that you are trying to do use "Commingled" for each of the four materials with a total volume instead of using "Diverted" with a volume for each specific material? (In this case, "Total Waste" is the waste quantity for each material - not the total waste for the entire commingled volume.) I'd use "Diverted" for the materials as noted in the first bullet that you have volumes for and then input the remaining volume under "Commingled" (or "Landfill Waste"). Does that help?

If none of the above helps, you can either follow my advice from 2/4/18 or complete these steps:

1. Use Special Circumstances on the v06 form in LEED Online and say that due to a perceived form calculation error, you had to revert to the earlier form version.
2. Go to the Credit Library (https://www.usgbc.org/credits/commercial-interiors/v2009) to navigate to MRc2 (https://www.usgbc.org/node/1731280?return=/credits/commercial-interiors/...). 
3. In the right sidebar Sample forms, download the Active Form under Version: v04.
4. Complete the form and upload it to LEED Online along with your spreadsheet backup.

Please let us know what worked above (if anything) for you.

BTW - My experience has been that weight usually gets you a higher overall percentage recycled than volume. Have you considered converting your volume to weight?
