<br />analyses, construction observation, soils and materials testing, and quality control and quality assurance
<br />(QA/QC). He has analyzed and designed shallow and deep foundations for residential and industrial
<br />projects; analyzed lateral earth pressures for shallow and deep excavations, including storm drain pipeline
<br />and storm water pumping plants for water municipal projects; performed slope stability analysis for
<br />transportation projects; reviewed geotechnical and geological reports and grading plans; monitored
<br />technicians' performance on soil grading and field density testing projects; evaluated soils liquefaction for
<br />water municipal projects; and performed quality control and quality assurance during deep ground
<br />improvement, including deep soil mixing, stone columns, vibro-concrete columns, cement grout injection,
<br />and deep dynamic compaction (DDC). Mr. Sandoval's experience covers a varied range of projects,
<br />including highways, freeways, parking lot structures, bridge foundations, airport runways, ports, high rise
<br />buildings, commercial, industrial, housing, storage tanks, earth and rock dams, mechanically stabilized
<br />embankment walls (MSE walls) , stream channels, storm drains, sewer lines, and water treatment plants.
<br />Professional Experience
<br />OCTA OC Street Streetcar, Orange County, CA — Senior field engineer for a two -track streetcar system
<br />from the Santa Ana Regional Transportation Center (SARTC) in Santa Ana to the proposed Regional Transit
<br />Connection and Station in Garden Grove, approximately 4 miles. The project also included design and
<br />construction of maintenance and storage facility and two new bridge structures. DYA provided a
<br />geotechnical investigation for the entire alignment, including soil borings, laboratory analysis, engineering
<br />analyses, and reports; they also performed an environmental site assessment in OCTA's Pacific Electric
<br />Railway right-of-way from Harbor Boulevard to North Raitt Street. Mr. Sandoval observed excavation,
<br />backfill, and compaction operations for footings. He provided soil improvement recommendations.
<br />RCTC I-15 Express Lanes Design -Build, Riverside County, CA — Senior field engineer for design -build
<br />project to improve traffic flow and reduce congestions on I-15 between Cajalco Road Interchange and SR-
<br />60 by constructing two tolled express lanes in each direction. DYA's scope of work included geotechnical
<br />investigations for all roadway sections and preparation of Materials Reports, Geotechnical Design Reports
<br />for roadway sections and soundwalls, and Foundation Reports for retaining walls. Most improvements
<br />were within Caltrans right-of-way, with a majority of improvements occurring within existing I-15
<br />median. Mr. Sandoval performed field services, including data review, permits, soil borings, and
<br />infiltration testing for roadways, retaining walls, sound walls, and overhead signs.
<br />Metro Expo LRT Storm Drain Protection Evaluation, Los Angeles, CA — Project engineer for
<br />additional services to evaluate the effects of the proposed La Brea and La Cienega Aerial Structure approach
<br />embankment portions of the proposed LRT project on an existing adjacent County of Los Angeles storm
