<br />Irvine Trabuco/Remington Traffic Signal, Irvine, CA — QA/QC reviewer for a project to install new traffic
<br />signal poles, provide new pavement, and widen the left -turn lane pockets along Trabuco Road, which will
<br />require a retaining wall. DYA provided a geotechnical investigation, including data review, subsurface
<br />investigation, laboratory testing, engineering analyses, and a report with recommendations for geologic and
<br />seismic hazards, site preparation and grading, foundation types and allowable bearing capacity, estimated total
<br />and differential foundation settlements, resistance to lateral loads, pole foundation, new pavement thickness,
<br />and soil corrosion potential. Mr. Niranjanan provided QA/QC review of the report and recommendations.
<br />Norwalk Foster Road Rehabilitation, Norwalk, CA — Geotechnical manager for project to rehabilitate the
<br />pavement from Studebaker Road to Pioneer Boulevard. The design included pavement rehabilitation
<br />strategies, signing and striping, traffic signal loop detectors replacement, utility coordination, storm drain inlet
<br />CPS, upgrade ADA ramps, spot curb and gutter replacement, and spot sidewalk replacement. Mr. Niranjanan
<br />provided project direction, developed the field investigation program, reviewed the engineering analyses, and
<br />provided recommendations in the geotechnical report.
<br />Bristol Street & Baker Street Intersection Improvements, Costa Mesa, CA — Geotechnical manager for
<br />the addition of a third eastbound and westbound through lane on Baker Street approximately 200 feet long in
<br />both directions west of the intersection of Bristol Street and Baker Street. DYA performed a subsurface
<br />investigation, laboratory testing, engineering analyses, and a geotechnical report with recommendations for
<br />earthwork and grading, corrosion potential and new flexible and rigid pavement sections. Mr. Niranjanan
<br />developed and coordinated the field investigation and analyses and prepared the geotechnical report with
<br />recommendations.
<br />Washington Boulevard Reconstruction, Commerce, CA — Geotechnical project engineer for final
<br />engineering and design recommendations for a road widening and pavement rehabilitation project along
<br />Washington Boulevard that extends from the I-5 freeway on the east to the City of Commerce's westerly limit,
<br />approximately 350 feet west of Indiana Street. DYA services included conducting a field exploration
<br />including soil borings and falling weight deflectometer studies, performing laboratory testing, performing
<br />engineering analyses to develop pavement and earthwork recommendations, and preparing a report with final
<br />design recommendations. Mr. Niranjanan provided direction for the field investigation, reviewed the
<br />analyses, and assisted with preparing the report.
<br />Mitchell Avenue Storm Drain, Tustin, CA — Geotechnical project engineer for the proposed Mitchell
<br />Avenue storm drain and street rehabilitation project, between Newport Avenue and Red Hill Avenue. The
<br />project was approximately 2,600 feet long and consists of the construction of storm drain laterals, the lining -
<br />in -place of the existing storm drain, and rehabilitation of the pavement surface of Mitchell Avenue. The scope
<br />of work included an RCP storm drain, connection of existing catch basins to new storm drain, new curb returns
<br />and handicap ramps, asphalt concrete rehabilitation with new asphalt surface course overlaid on the street,
<br />and removal and replacement of damaged sidewalks and traffic signing and striping. DYA conducted a
<br />geotechnical investigation and prepared a report with recommendations regarding pavement design and
<br />rehabilitation, type and strength of concrete to be used for structures, any special trenching requirements, and
<br />other recommendations for the construction of the project. Mr. Niranjanan performed engineering analyses
<br />and input to the report recommendations.
<br />Gisler Avenue Rehabilitation, Costa Mesa, CA — Geotechnical manager for the reconstruction of an
<br />approximately 4,500-foot-long reach of Gisler Avenue, from Harbor Boulevard to 100 feet west of Nebraska
<br />Place. Soil conditions, tree roots, and utility work contributed to the deterioration of sections of pavement,
<br />curb and gutter, and sidewalk. The project consisted of roadway reconstruction and storm drain replacement.
<br />DYA conducted a subsurface investigation and performed laboratory testing and engineering analyses to
<br />provide geotechnical input for the design of the project. Mr. Niranjanan provided project direction and
<br />developed conclusions and recommendations regarding pavement thickness, site preparation and grading, and
<br />corrosion potential.
