AASHTO re:source Q & A Podcast

Some people call them gigs, docks, dings, notes, or deficiencies. CCRL calls them footnotes. AASHTO re:source calls them findings and classifies findings into 2 categories: observations and nonconformities. We learn the differences and discuss some best practices on how to resolve them.
