We are trying to re-use existing regular gravel from the site for the concrete mix of the new building. Will that qualify for materials reused credit? We will have to take existing gravel to the plant, have it run it through the sieves and see what % of it could be used. Thanks.

Maria, from one angle, I would say that this definitely qualifies. From another angle, it seems like a stretch. Was the gravel a native feature of the site, or was it added at some point?

Actually, I think it was added when the existing building was operating. Then, the owner demo the ex'g building few years ago, and left the site. When we got the site, it was just a concrete slab and regular gravel all over the site. I thought reusing the gravel could be a good idea.

Hi, I have a similar situation in one of our projects. Due to excavation works, we will get a good volume of gravel (naturally on site) that could be used for pervious pavement in the parking lot or as aggregate for the concrete mix. Do you think this could be taken into account for MRc3? If not, it may work for MRc2 and/or MRc5, since we would be deviating this material from local landfills and it is of course a material extracted on the region. What do you think? Thank you!

Its seems to me since the gravel will excavated, then used in another function (pervious paving) that you would be able to count it for MRc3 and MRc5. I don't think you could use it for MRc2 unless you separate it from any soil or other land clearing debris to be diverted from the landfill since soil and organic matter are not counted in the calculations.
