Steve McMullen, PE, LEG

Vice President

Steve is a geotechnical engineer with 30 years of consulting and project management experience.  He’s worked on a variety of transportation, development, and utility infrastructure projects during his career, though his primary focus has been on railroad services.  Steve has worked for five of the major Class 1 railroads and numerous regional and short lines on projects located in 26 states and two Canadian provinces.  He’s performed geotechnical and geological evaluations for proposed, new railroad corridors up to 320 miles long and conducted geotechnical condition assessments of existing rail lines up to 600 miles long.  On several projects involving litigation over railroad shipping rates, he’s performed in-depth analyses of geotechnical issues affecting construction and operating costs of conceptual rail lines ranging in length from 175 miles through one southwestern state to over 2,000 miles through 18 states in the eastern U.S.  Steve’s geological engineering background gives him an appreciation of the diverse geologic conditions that can be encountered, and how those conditions can impact railroad design, construction, operations, and maintenance - not only on long rail corridor projects, but on individual sites as well where soil and rock characteristics can change within a few feet.

Steve's railroad projects often involve the design and construction of landslide and embankment stability improvements where he oversees field reconnaissance, subsurface explorations, engineering analyses and design, bid document preparation, and construction management.  He also has experience with rockfall hazard assessments and mitigation methods; design of deep foundations for bridges; geotechnical design for double-track and siding extensions; track substructure design; erosion protection and riverbank stabilization; tunnel inspection and rehabilitation; excavation shoring; and retaining walls.  Many of Steve’s projects involve emergency response following railroad track outages caused by natural hazards such as landslides, floods, and erosion.  With 27 years of experience in these situations, he can rapidly assess site conditions and provide recommendations, without the benefit of explorations or analyses, so that construction of repairs can start and rail service can be restored as quickly as possible.
