Dr. James G. Collin, P.E., founded The Collin Group, Ltd., in 1995. Over the last two decades, The Collin Group has been involved with the design and construction of 15 column supported embankment projects across the US. As part of this work Dr. Collin conducted column (pile) load tests to verify the design capacity of the columns. Dr. Collin was the principal investigator for a FHWA research program to develop design guidelines for column supported embankments and co-authored the FHWA Design Manual on Deep Mixing for Embankment and Foundation Support.
The Collin Group has performed over 100 investigations of geotechnical failures including MSE walls, reinforced soil slopes, shallow and deep foundations, column supported embankments, landslides, and ground freezing.
Dr. Collin is the author of the National Highway Institutes “Soil Slope and Embankment Design Manual”, “Slope Maintenance and Slide Restoration Manual”, “Ground Improvement Methods Manual,” and “Shallow Foundations Manual”. Dr. Collin is also a certified instructor for the Federal Highway Administration courses on Ground Improvement, MSEW and RSS Design and Construction Guidelines, Soil Nail Wall Design, Earth Retaining Structures, Geosynthetic Design and Construction Guidelines, Shallow Foundations, Soil Slopes and Embankments, Slope Maintenance and Slide Restoration, and Geosynthetics. He was recognized by NHI as an “Instructor of Excellent” in 2008, 2009, 2011, and 2012.
Dr. Collin has been a member of ASCE since 1985. He is a fellow and a Diplomat of Geotechnical Engineering with ASCE. He is currently on the board of governors of the Geo-Institute.
