Hi all,
We are curious how folks are gathering their material quantities per the pilot credit language "Material quantities shall reflect the final as-built project and be consistently drawn from either the 100% CD Construction Estimate, 100% CD BIM bill of materials, or Contractor procurement data". We've been finding it challenging on a few projects that are pursuing this credit to get these numbers easily.
One method we've been looking at has been using TallyCat to pull quantities into EC3 from the 100% CD Revit model, but are finding there's a somewhat tedious QC process in EC3 after import as not everything in Revit is modeled as it is built in real life. On another project, the Contractor team approached this more "manually" combing through procurement info.
Any thoughts or experience with this is appreciated!

Hi Kelli,
in our case it was helpful for us to have already done the LCA on the project through Oneclik LCA. From there it was easy to export a report with the quantities already divided by categories and apply them for the Pilot credit. Definitely it was complex the process of entering the quantities on the software because, as you pointed out, not everything had been modeled on Revit so we had to add elements manually on Oneclcik. But once all the materials were entered, it was easy to both perform the LCA and pursue the Pilot credit.
Best regards!

For three projects we have seen the general contractor send out Carbon Reporting forms to their subcontractor teams. These forms typically track the manufacturer name, product name, mill location or manufacturer locations, a place to include the quantity information in the specified units, and an attachment of the relevant EPD. This is managed during the submission process.
The LCA approach is helpful for setting up EC3 and having in place all relevant EPD information from the design. However the submission approach allows the general contractor to make updates based on actual procurement. The happy medium here will be an LCA import, and contractor verification through submission. Allowing for the flexibility of editing quantities and allowing for the change of products.
