<br />Professional Experience
<br />OCTA OC Streetcar Project, Santa Ana, CA -- Geotechnical manager for the design and construction of a two -
<br />track streetcar system from the Santa Ana Regional Transportation Center In Santa Ana to the proposed Regional
<br />Transit Connection and station in Garden Grove, approximately 4 miles long. The project includes design and
<br />construction of 2 -story maintenance and storage facility building and two now bridge structures (Santa Ana
<br />Bridge and Westminster Avenue undercrossing). The maintenance and storage facility is planned to house all light
<br />revenue maintenance functions, including operations. This will accommodate administration, operations,
<br />maintenance, repair bays, and parks storage. A maintenance building, a wash building, parking lots, and a fire lane
<br />are proposed for this facility. Responsible for reviewing existing gaotechnicel/goologleal date, coordinating
<br />permitting process for geotechnleal encroachment permits from various agencies such as OCTA, City of Santa
<br />Ana, and County of Orange, coordinating subsurface explorations, assigning laboratory testing performed
<br />engineering analyses, attending design meetings, and preparing gootachnical reports with geotechnical
<br />recommendations in accordance with Caltrans guidelines.
<br />Jamboree/Sarranco Interchange Improvement, Irvine, CA — Geotechnical project engineer for improvements to
<br />the Jamboree/Barrance Intersection in Irvine, The Improvements Include the addition of a fifth northbound lane on

<br />Into the Griswold property; construction of new pavement, curb and gutter, sidewalk, and access ramps; and
<br />rotovation of a storm drain. DYA's services included securing encroachment permits, conducting a geoteohnical
<br />subsurface exploration, performing laboratory tests on selected soil samples, performing engineering analyses to
<br />develop conclusions and recommendations regarding subsurface conditions, alto preparation and grading,
<br />bedding and backfill, pavement thickness for new pavements, and soil corrosion potential; and preparing a
<br />gootechnical report, Mr. Niranjanan coordinated the field investigation and conducted analyses.
<br />Bristol Street and Baker Street Intersection improvements, Costa Mesa, CA — Geotachnical manager for the
<br />addition of a third eastbound and westbound through lane on Baker Street approximately 200 feet long in both
<br />directions west of the Intersection of Bristol Street and Baker Street, DYA performed a subsurface Investigation,
<br />laboratory testing, engineering analyses, and a geoteohnical report with recommendations for earthwork and
<br />grading, corrosion potential and new flexible and rigid pavement sections. Mr. Niranjanan developed and
<br />coordinated the field investigation and analyses and prepared the gootachnical report with recommendations.
