BEN HUSHMAND, PhD, PE
President, Geotechnical & Earthquake Engineer/Faculty Associate, Caltech
Dr. Hushmand's 30 years of experience includes consulting, research, and teaching. Dr. Hushmand received his PhD degree from Caltech in 1983 and has been a faculty associate at Caltech teaching and performing research in geotechnical and earthquake engineering since 1990. He performs and supervises geotechnical and seismic engineering investigations, design, and construction management for transportation and public works projects, ports and harbors, municipal and hazardous solid waste landfills, commercial and residential developments, dams and reservoirs, and water and sewer treatment plants. Dr. Hushmand has worked on some of the most challenging geotechnical and earthquake engineering projects including geotechnical and vibration studies of the National Ignition Facility (NIF) at four Department of Energy (DOE) national laboratories in California, Nevada, and New Mexico; seismic monitoring of OII Superfund site in Monterey Park, California; seismic hazard evaluation and design for Emergency Management (911) Centers for City of Long Beach and for Transportation Management Centers in County of Orange and Riverside/San Bernardino Counties for CalTrans; MX (intercontinental ballistic missile sitting) project; Port of Los Angeles 2020 project; Superconducting Super Collider (SSC) project in Texas; Metro Rail project in Los Angeles; and low- and high-level nuclear waste storage programs in California, Nevada, New Mexico, and Texas.
Dr. Hushmand's pioneering work in dynamics of foundations and seismic instrumentation and monitoring of liquefiable sites and landfills is internationally recognized. He has been a consultant for the USGS, Nuclear Regulatory Commission, DOE, and the EPA studying earthquake ground motions and dynamic behavior of foundations and landfills. Dr. Hushmand is a member of the American Society of Civil Engineers, Earthquake Engineering Research Institute, Seismological Society of America, and is a Registered Civil Engineer in California. He has also authored or coauthored more than 100 technical papers and reports.
During his nearly 30 years of diverse experience in the fields of geotechnical and geo-environmental engineering he has acted as lead engineer and project manager for numerous projects in both the public and private sectors that included road and bridges, pipelines, earth retaining structures, landslide mitigation, landfill expansion design and closure, utilities and water resources, military base cleanup, educational facilities, and essential service buildings. His areas of technical expertise include seismic hazards evaluation, foundation design and retrofit, shoring design, instrumentation for construction monitoring, and ground improvement techniques. His well-rounded technical background and effective approach in both project and client management enables him to provide practical solutions to both complex and day-to-day challenges of environmental and geotechnical engineering design and construction projects.
Mr. Turbay received his MS degree in Geotechnical and Civil Engineering from Los Andes University in Colombia and his BS degree in Civil Engineering from Del Norte University, Colombia. He has extensive experience in geotechnical engineering projects for water resources, highways, bridges and electric power plants. Mr. Turbay has been involved in geotechnical investigations, drilling, soil testing, construction field inspections, management of construction quality assurance projects, dynamic soil properties characterization and one-dimensional soil response analysis, and analysis of field and laboratory data to characterize subsurface soil layering and properties for use in engineering analyses to develop geotechnical design parameters for foundation design, pavement design, slope stability analysis and design.
Ms. Mokarram received her PhD degree in geotechnical engineering from University of Southern California and her MS degree in Earthquake Engineering from University of Tehran. She specializes in soil-structure interaction, seismic hazard and risk analysis, soil improvement and numerical analysis. Ms. Mokarram has extensive experience in geotechnical and earthquake engineering projects for commercial and industrial facilities such as acid plants, recreational and educational facilities such as bike trails and schools, water reservoirs, bridges, and landfills. Ms. Mokarram has also been involved in construction quality assurance, construction feasibility study, slope stability, 2D site response analysis, ground water monitoring, and site specific probabilistic ground motion assessment projects.
Mr. Hushmand received his MS degree in Civil Engineering from University of California, Los Angeles and his BS degree in Civil Engineering from University of California, Irvine. He has experience in vibration monitoring and dynamic analysis for sensitive projects, CQA for installation of driven and drilled piles for bridges, CQA for installation of shoring, and conducting bulk density and bulk gradation tests. He also has experience in drilling, design of shallow and deep foundations, slope stability analysis and numerical analysis using FLAC. Mr. Hushmand has been involved in projects related to bridge widening, solar power plants, road widening, backfilling, and bike trail design.
Mr. Bellana received his MS degree in Geotechnical and Civil Engineering from University of California Los Angeles (UCLA) and his BS degree in Civil Engineering from Indian Institute of Technology, Guwahati, India. He has experience in geotechnical engineering projects for water resources, bridges and backfills. Mr. Bellana has been involved in geotechnical investigations, drilling, soil testing, dynamic soil properties characterization and one-dimensional soil response analysis, and analysis of field and laboratory data to characterize subsurface soil layering and properties for use in engineering analyses to develop geotechnical design parameters for foundation design, pavement design, slope stability analysis and design. Mr. Bellana along with Dr. Scott Brandenberg developed correlations between shear velocity (Vs) and energy-corrected SPT blow count (N60) in collaboration with CALTRANS for his M.S. thesis at UCLA.
Mr. Nitha received his MS degree in Geotechnical and Civil Engineering from University of Nevada, Reno (UNR) and his BS degree in Civil Engineering from University of Peradeniya, Sri Lanka. He has experience in geotechnical projects for landfills, water resources and backfills. He has been involved in field investigation, slope stability analysis, liquefaction analysis, site response analysis and analysis of field and laboratory data to characterize subsurface soil layering and properties for use in engineering analyses to develop geotechnical design parameters for pavement design, and slope stability analysis and design.
PETER E. MOORE
Soils/Concrete Laboratory and Field Technician
Mr. Moore has more than 35 years of experience as a construction quality assurance monitor working on a variety of geotechnical engineering projects involving massive grading activities, slope stabilization, foundation preparation and installation, directional drilling, subdrain installation, injection/grouting stabilization, and field instrumentation for construction and post-construction monitoring. Mr. Moore's extensive experience in geotechnical field investigation and laboratory testing has provided him with exceptional in-depth understanding of soil behavior and foundation construction. Mr. Moore has worked on a wide range of geotechnical and environmental engineering projects such as slope stabilization; reservoirs; power plants; residential, commercial and industrial developments; roads, and bridges.
