Christopher is a geological engineer with a wide variety of experience in geotechnical engineering, engineering geology, and geological hazard assessment and mitigation design. The majority of his experience has involved providing geotechnical engineering support, geological hazard assessment, and mitigation design within the transportation industry for both rail and highway infrastructure. He also has experience providing geotechnical support for the mining industry, water and wastewater infrastructure, and underground tunnel rehabilitation.
Christopher has worked on multiple projects involving investigating and providing geotechnical solutions for a variety of geological hazards including emergency response involving rockfall and rock slope stability, swelling/collapsible soils, mine subsidence and sink holes, coal mine fires, soft soil settlement, tunnel collapse, landslides, embankment failures and washouts, and debris flows. He has responded to dozens of these emergencies for BNSF, UPRR, and CDOT. In addition, Christopher has worked as a full-time resident engineer for a variety of construction projects, including several tunnel rehabilitation projects, compaction grouting projects to mitigate mine subsidence, emergency landslide stabilization projects for rail corridors, soil nail wall construction, rock slope excavation and stabilization, and earthwork projects. Many of these projects required modification of the design during construction to accommodate changed conditions, constructability issues, and schedule constraints
