Gangjin Li is a geotechnical engineer with over 15 years of consulting and academic research experience in civil infrastructure. He has been appointed as a technical expert on 14 occasions.
Gangjin has advised on geotechnical disputes through negotiation, arbitration, and dispute resolution boards. He has performed peer reviews of contractual plans and specifications, compliance with design codes and standards, risks and opportunities assessment, and forensic analyses to determine root causes of structure and earthwork failures.
Gangjin has experience as a contractor and designer with knowledge in temporary works design, including shoring of excavation (e.g. soldier pile wall, sheet pile wall, soil nail wall), working platform design, and pile driving and extraction analysis. He has assisted clients with geotechnical analysis and design on over 60 large-scale transport infrastructure projects, which involved numerical modelling, slope stabilization and landslide mitigation, including spread footings, driven piles, and drilled shafts for bridge and retaining wall foundations, earth-retaining structures for cast-in-place concrete walls, mechanically stabilized earth walls and sound walls, along with short and long-term settlement analysis for foundations and earth fills. Gangjin has performed seismic hazard evaluations and seismic vulnerability assessments, liquefaction evaluations and mitigation, soil pile interaction in lateral-spreading ground induced by liquefaction, and site response analysis.
Gangjin’s expertise includes differing site conditions, piping failure of cofferdams, cracks of diaphragm walls, quantity overrun of backfill materials, instability of cut slopes, overdosage of concrete during construction of secant pile walls, load test failure of drilled shafts, large deflections of retaining walls, excessive settlements of fill embankments, and instability of excavated trenches. He has been engaged as a subject matter expert throughout the life cycle of high-profile civil infrastructure projects, such as California high-speed rail, Brightline West high-speed rail, Harbor bridge replacement, and Hampton roads, bridge and tunnel.
Gangjin holds a doctorate in geotechnical engineering and is a professional engineer in Washington, California, Nevada, Texas, Alabama, New York, Maryland, Virginia, and North Carolina. He is a member of the American Society of Civil Engineers and associated Geo-Institute, the Deep Foundation Institute and associated technical committees of anchored earth retention and driven pile, and the International Society for Soil Mechanics and Geotechnical Engineering. Gangjin is bi-lingual in Mandarin and English.
