As Principal in Charge of all CSA civil and geotechnical engineering projects, Mr. Shires’ responsibilities range from investigation, analysis and product review to final design participation and project management for large projects. Mr. Shires remains actively involved in the engineering investigation, design, construction, and review for technical investigations. In addition, he is qualified as an expert witness in Civil/Geotechnical Engineering and has testified at over 67 trials and binding arbitrations as an expert witness, including trials resulting in landmark legal decisions involving natural watercourse and earth movement issues.
Mr. Shires has over 33 years of professional experience in the fields of civil and geotechnical engineering throughout the western United States. In the early part of his career, he supervised the technical investigation and engineering analyses for many water and wastewater treatment and distribution facilities, dams, nuclear- and fossil-fuel power plant and high-rise building sites throughout the western United States. He investigated over 50 dam sites and was the chief design engineer for a 160-foot high rockfill dam in Arizona.
At his present position, Mr. Shires has specialized in slope stability investigations on over 350 landslide projects, 30 of which have been in southern, 11 in central, and over 300 in northern California, and nine in Hawaii. He has supervised many major landslide investigation projects, including the Big Rock Mesa, Rambla Pacifico, and Anaheim Hills landslides in southern California; the Love Creek, Permanente Quarry, Codorniu Napa and hundreds of other landslides in northern California; and the Manoa, Ailuna-Leighton and other landslides in Hawaii, as well as flooding issues associated with major storm events on the big island of Hawaii. In addition, he has specialized in the investigation of failures associated with river and creek flooding, including levee failure and design issues. Mr. Shires regularly participates in International Field Workshops on Landslides, including workshops in Japan, Australia, New Zealand, Switzerland, Austria, Italy, Czech Republic, Slovak Republic, Spain and England. He is experienced in the use of sophisticated slope stability analysis tools, including two- and three-dimensional limit equilibrium methods and finite element modeling.
Mr. Shires has specialized in the design of remedial measures for dealing with slope stability problems, including the design of grading plans, retaining wall structures, shear pins, tiebacks and extensive drainage works. He has been the chief design engineer on over 100 landslide repair projects, including designing a coastal revetment to protect the Esplanade Avenue bluff in Pacifica and extensive slope repairs to protect homes below the Knockash Hill rockslides in San Francisco. He investigated landsliding for the Yangtze Water Resource Commission's Three Gorges Dam project in China and is the MTA geotechnical engineering expert for their Redline Tunnel distress litigation in Los Angeles
