Principal Geotechnical Engineer – David H. Lee, PE, GE
Mr. Lee is the primary management contact with the City, and the person responsible for day-to-day work for all geotechnical services. Mr. Lee is the founder and Principal Geotechnical Engineer of DHLA, and has over 40 years of experience in the field of Geotechnical Engineering. His extensive geotechnical design and construction experience includes the new development of residential, commercial and industrial foundations, retaining structures, and public works infrastructure projects including roadways, pipelines, and harbor improvements. He has performed numerous landslide evaluations and structural assessments of damages due to earthquake, groundwater, and construction defect hazards, serving various clients including insurance companies, law firms, property managers, and public agencies. He has over 20 years of forensic experience and has been deposed as an expert witness between 250 and 300 times, testifying in court over two dozen times. He has authored technical articles pertaining to construction of floor slabs and landslide stabilization, and has served as an officer with local civil engineering professional organizations. Mr. Lee is the full-time Principal Geotechnical Engineer who will be reviewing all geotechnical matters. Senior Engineering Geologist – Colin Cunningham, PG, CEG
Mr. Cunningham has over 25 years of engineering geology experience in the geotechnical consulting industry. His project experience includes new development of residential, commercial, and infrastructure sites, for which he has performed site investigations of geologic hazards, geologic mapping and down hole logging of subsurface conditions, and monitoring of geologic conditions during earthwork construction. He has conducted numerous evaluations of major landslides, groundwater migration, and earthquake-related damages in the Southern California region, serving various clients including insurance companies, law firms, property managers, and public agencies. His geologic background also includes petroleum and energy experience, such as offshore and land-based exploration and production drilling operations in the Santa Barbara Channel and San Joaquin Valley of California, geothermal drilling exploration in California's Coachella Valley, geologic and geophysical assessment of petroleum prospects, and management of exploration data. Mr. Cunningham is a full-time Senior Engineering Geologist who will be reviewing all geological matters. Project Engineer - Karen Geraci, PE
Ms. Geraci has over 10 years of experience as an engineer with a background in engineering geology. Her specific duties include but are not limited to boring and trench logging and sampling, laboratory testing, construction oversight and observation, slope stability and engineering analysis, geotechnical design of earthwork including buttress stabilization, interpretation and mitigation of geologic/seismic hazards, design of foundations, slabs, and pavements, and structural damage assessments for litigation and insurance claims. In addition she has been directly responsible for coordinating the activities of staff geologists, engineers, and field technicians during these assignments. Her experience includes geotechnical investigation and construction phases for a wide variety of private- and public-sector projects in Southern California, including residential and commercial/retail developments, hospitals, schools, and public works infrastructure projects. Ms. Geraci has been a contributing third party geotechnical reviewer in tandem with a Certified Engineering Geologist for the cities of Rancho Palos Verdes, Laguna Beach, Dana Point and San Juan Capistrano. Senior Engineering Technician – David E. Lee
Mr. Lee has extensive experience as a field engineering and laboratory manager for various geotechnical engineering projects. His duties have included boring and trench logging and sampling, installation and monitoring of slope inclinometers, groundwater wells, and pore pressure transducers, data reduction and engineering interpretation, laboratory testing, on-site construction observation and field density testing for large-scale mass excavations, retaining structures including tieback anchor and soil nail installations, tilt-up building construction, reservoirs, roadways, and heavy pipeline and utility installation projects. He is currently certified as a radiation safety officer for use of nuclear gauge testing equipment. Since Mr. Lee is currently enrolled in the California State University Civil Engineering Program he uses the knowledge gained in class in practical application in the field in order to give DHLA the highest level of technical support possible. Field/Laboratory/Drafting Technician – Hani Alikhwan
Mr. Alikhwan provides drafting, laboratory testing and field technician services for various geotechnical engineering projects. His duties have included soil sampling, floor level survey, monitoring of slope inclinometers, laboratory testing, data reduction, on-site construction observation and testing, and computer-aided drafting. He is proficient in AutoCAD and provides graphics support for generation of site plans, geologic maps, cross sections, geotechnical logs, engineering specifications, and other technical drawings for geotechnical engineering design and construction projects. His workstation is equipped with an Epson Stylus C84 color printer, an Epson Stylus Photo 2200 color printer, a Hewlett Packard Scanjet scanner and a Hewlett-Packard 750c+ plotter. Mr. Alikhwan is a student at California State University – Long Beach. Upon completion he will hold a Bachelor of Science Degree in the field of civil engineering. His classroom experience contributes to our company’s mission of excellence in geotechnical consulting at every level of employment. Administrative Manager – Sandra Hull Ms. Hull is DHLA’s administrative manager and is responsible for payroll documentation, invoice receipt, approval and processing, monitoring of timesheets and expense reports, and preparation of the geotechnical portions of project invoices. Project Coordinator – JoLynn Tofani Ms. Tofani is DHLA’s project coordinator and is responsible for maintaining office files, project research, data entry, general office work and production of geotechnical reports. |
