Our project's waste quantity was recorded in truck load not in kilograms. This counts as volume? Shall we determine just an average volume for one truck load in any of the units in the calculator?
Thanks

Hi Miriam ~Is your waste commingled or does each "truckload" have a single stream? You will need to have the supporting documentation that validates the actual weight or volume measurement and it has to be consistent throughout the entire project. Do your haul reports simply state "1 truckload?"

Hello Tiffany, each truckload have a single stream which is Metal. The haul reports state just 1 truckload. Just like you said, we thought we must be consistent throughout.
For the other waste streams we have no problem, just for this one (Metal) since its unit is different and vague.
Just wondering if bulk or averages are accepted in case actual weight are not available?
Thank you very much!

Are you able to get the containment size of the truck to help with a conversion? I am not sure how USGBC might respond to the tally of the metal, but getting as much information as you can from your hauler that could help with the quantity conversion would be my suggestion. Then go ahead and do the conversion to get it into the same units as your other waste. Ultimately, I am not sure if it will be acceptable to GBCI, but capture as much as you can and see how the review comes back. This situation might warrant a direct conversation with your review team.

We had a similar situation in a recent project and received the below response from GBCI:
As long as the material in the truck hauls is accurately estimated (i.e. you have a record that all hauls are full truckloads which is a set volume of material, etc), the team can then use the LEED or EPA conversion values to convert the waste volume over to weight. Note that it is not allowable to visually estimate the percentages of various materials within commingled loads. Only an actual volume measurement or actual weight measurement is allowable, however it is permissible to then use that measurement to convert from volume to weight or weight to volume using the LEED or EPA conversion values.
