Break-out lab and demo sessions round out each day of instruction, providing attendees with hands-on experience in these areas:

EPB Soil Conditioning Experiment with different foams and polymers to see how these additives influence the behavior of a variety of soils.

Rock Cutting Explore hard-rock cutting principles and challenges with samples of fractured rock.

Slurry Design, batch, and examine, a variety of slurries used in tunneling environments via numerous test methods.

EPB TBM Simulator Operate an EPB TBM in a virtual environment; learn how to control face pressure, control ground deformation and advance speed through interactive trial and error.

Numerical Modeling Work through numerical modeling exercises, highlighting modeling assumptions and limitations for tunneling applications.

Shotcrete Learn and implement shotcrete mix design fundamentals, participate in wet and dry mix spraying, and perform verification tests on fresh and mature shotcrete.

Blasting Design Design the blast round for a tunnel heading based on cut, face, buffer and contour line holes; discuss charge density to achieve high yield and minimal wall damage.

Annulus Grout Learn mix-design fundamentals and perform simple tests with grouts, fibers, steel and polymers.

Abrasivity and Wear Lab Review fundamentals of rock and soil abrasivity and evaluate abrasivity in geomaterials.

Tunneling Geology Walk Learn about applied geology and geotechnical characterization of rock masses for tunneling during an outdoor exploration of rock outcrops in Golden, Colorado.

3D Geotechnical Site Investigation and BIM Work with 3D renderings of geotechnical site investigations and discuss tunnel alignment and building information management (BIM).
