Construction on the Virginia Tech Carilion School of Medicine continues moving forward, though much of the progress isn't visible above ground. You may have noticed what appears to be a large funnel appearing in various places on the site. Workers are creating "Geopiers" - drilling holes and filling them with a stone aggregate material to create solid foundation columns that go down through loose soil to rest on firmer layers.
The other buildings in the Riverside Center, Riverside 1 and the Carilion Clinic outpatient facility, also rest on Geopiers.
