Mr. Andrew Dinsick
Professional Engineer, GeoPentech
Mr. Andrew Dinsick has over 23 years of experience in the field of geotechnical and earthquake engineering. He was awarded a Bachelor’s of Science degree from Duke University in 2003 in the field of Civil Engineering, he obtained registration as a Professional Engineer in the State of California in 2008 and was awarded a Master’s of Science degree from UCLA in 2012, having studied Geotechnical and Earthquake Engineering. His role as an Associate at GeoPentech has included the analysis of subsurface information on a wide range of infrastructure projects, with specific emphasis on seismic hazard evaluation and mitigation. Common project experience has included infrastructure facilities such as bridges, dams, reservoirs, tall buildings, pipelines, roadways, tunnels, and power plants including nuclear facilities. His expertise includes characterization of subsurface material static and dynamic properties, liquefaction evaluation, seismic hazard analysis and ground motion characterization.
Mr. Dinsick has led a team of experts at GeoPentech to develop site-specific ground motion response spectra and acceleration time histories on more than 80 performance-based design peer review projects, predominantly in Southern California. The design criteria for new buildings in this portfolio was typically conducted under the Los Angeles Tall Buildings Structural Design Council guidelines and was in general accordance with ASCE 7. Structures that required ground motions for seismic retrofit work were carried out and peer reviewed in general accordance with ASCE 41 guidelines. Typical project experience has consisted of site characterization, probabilistic and deterministic seismic hazard assessment calculations, ground motion time history selection/modification and finally participatory peer review. Specific examples of Performance Based design of Tall Buildings include: the Metropolis Towers, the Times Mirror Square development, One Beverly Hills, the California Science Center Shuttle Stack, 8th and Olive, 9th and Fig, Sunset and Wilcox, Sunset and Gordon, Cumulus District Tower, Perla on Broadway, LA City Center, The Beaudry and Oceanwide Plaza towers.
