At RIZZO our early involvement in tunneling came about naturally as a result of our work providing water conveyances schemes for hydropower and cooling water schemes for nuclear power plants. In recent years our work on tunnels and shafts has expanded to a myriad of applications on projects around the world including Water Conveyance, Transportation, Mine Access, and Pipeline Routing through both hard rock and soft ground. From mass transit routes below the streets of New York City to vehicle routes through the Andes Mountains, we take pride in the international breadth of our tunneling achievements.
In addition to providing complete tunnel design services, we have experience in developing geotechnical investigation programs and authoring Geotechnical Baseline Reports, evaluating tunnel and underground structure designs against seismic loading criteria, producing hydraulic models for fluid flow through tunnels, and providing construction management services.
RIZZO’s projects have garnered attention and accolades from engineering societies in the U.S. and abroad. We proudly served as the Engineer-of-Record for the award-winning Taum Sauk Upper Reservoir Rebuild, where our team developed solutions for rehabilitating the tunnels and shafts using the GIN Method of grouting with real-time monitoring.
