The project involved the demolition of a existing building that had asbestos present on it. Asbestos were removed prior to demolition and the process was properly documented for LEED.

During excavation works, a small portion of soil contaminated (with oil/diesel) was extracted, it was rejected from the landfill and moved to a special facility.

A survey of this soil was not conducted. Does this mean the credit is lost or can it be achieved only by documenting this remediation?
