Logan's practice experience includes geohazard mitigation, slope stability analysis, ground improvement engineering, foundation design, offshore geotechnics, and geotechnical investigation. His work has included significant contributions to helping clients conduct numerous complex onshore, nearshore, and offshore geotechnical investigations; providing engineering and design support; as well as field inspection and client technical representation services. Logan's clients benefit from his experience and knowledge of most sampling techniques, in situ test methods, and geotechnical laboratory tests. Some of his experience comes from a previous role managing a geotechnical testing laboratory. His geohazard mitigation experience has been primarily in support of pipeline projects in mountainous areas of the United States, including West Virginia, Ohio, Pennsylvania, and Virginia. His field experience offshore includes projects in Mozambique, Cote d'Ivoire, and British Columbia, Canada.
A consistent presenter at conferences, Logan has authored or co-authored 12 peer-reviewed technical papers and provides peer reviews for several leading technical journals, including ASCE's Journal of Geotechnical and Geoenvironmental Engineering and ASTM's Geotechnical Testing Journal. He is an active member in ASTM's Committee D18 and is currently on both the Executive and the Offshore Site Investigation & Geotechnics (OSIG) Committees of the U.S.Branch of the Society for Underwater Technology (SUT). In 2011, he received the Richard J. Stromness Award of Excellence from the Pile Driving Contractors Association (PDCA). As an Adjunct Assistant Professor at Columbia University, he has instructed three different graduate level engineering courses.
