Mr. Frizzi’s geotechnical engineering and project management experience is extensive, with particular emphasis on: foundation design and construction in urban areas, and large-scale land and waterfront public and private development projects throughout the United States and internationally. During his over 28 years in the industry, he has consulted to private, public, insurer/surety, and attorney clients on projects located in practically every continent world–wide, and has performed geotechnical investigations and designs, prepared plans and technical specifications, and observed field testing and construction as geotechnical “engineer of record” on countless projects. Mr. Frizzi has obtained extensive field, office supervision, and project management experience including soil and rock sampling and in-situ testing; monitoring pre , during, and post-construction with state-of-the-art geotechnical instrumentation; nondestructive testing; aqueous and sub-aqueous inspections and investigations; and heavy construction which has contributed to his practical approach to geotechnical problem solving. Mr. Frizzi’s areas of expertise include: waterfront structures (wharfs, piers, levees, embankment dams, and flood protection infrastructure); brownfield site redevelopment; earthwork; tunnels; engineering shallow and deep foundation systems for super-tall structures, stadia, and arenas; soft and hard rock treatment; surcharging of organic soils and loose sand; temporary and permanent lateral support systems in deep excavations; geotechnical instrumentation and vibration monitoring; construction dewatering; and forensic investigations. In addition to his “engineer of record” experience, Mr. Frizzi has provided expert geotechnical consultation and trial testimony on over 50 excavation and foundation litigation cases throughout the United States and internationally.
