Christian Delgadillo, PE, GE
<br />Christian has experience in geotechnical engineering, construction observation,
<br />testing, data analyses, and report preparation for various types of public works,
<br />transportation, governmental and utility projects. His responsibilities include
<br />managing, coordinating and conducting subsurface investigations and develop
<br />12
<br />cross sections by logging and sampling hollow -stem auger borings and rotary wash
<br />borings, and supervising cone penetration testing (CPT), preparation of laboratory
<br />assignments, analyze computer models to predict slope stability for natural and
<br />1�
<br />manmade slopes, perform earthquake induced liquefaction and settlement analysis
<br />and identify the potential hazards, pavement rehabilitation and/or reconstruction
<br />design, develop recommendations for design, grading, and construction of various
<br />types of projects. His construction observation experience includes tie -back testing,
<br />overseeing full displacement cast in situ pile installation and testing, soil nail
<br />installation and testing, temporary soldier pile driving, and micropile installation
<br />and testing. He has an in depth understanding of advanced soil mechanics,
<br />subsurface interpretation, seismic hazard analyses, site specific ground motion,
<br />•
<br />expansion potential, liquefaction evaluation, slope stability, shallow and deep
<br />foundations, in situ testing and geotechnical instrumentation, pavement design
<br />and geotechnical engineering, in situ permeability determination, and laboratory
<br />analysis of soils.
<br />Project Engineer for a PFAS
<br />treatment facility for Wells 1, 5, 7, 10, 12, 18, and 19 at the District's headquarters that consists of 6 pre-
<br />treatment vessels and 22 new ion exchange (IX) vessels. Each vessel is 12-foot in diameter and 16.5-foot tall,
<br />supported on a 2.5-foot-thick mat foundation. Other improvements include a booster pump station, new
<br />piping, equipment, and site paving. The field exploration included exploratory borings to a depth of 50 feet
<br />since the site is located in a liquefaction zone. Developed geotechnical recommendations for the project,
<br />including mitigation measures for liquefaction potential, prepared a geotechnical exploration report, and
<br />provided inspection and testing services during construction. The project is one of the largest PFAS Systems of
<br />its kind to be installed in the country and can produce 19 million of treated groundwater per day.
<br />Project Engineer. Leighton conducted a
<br />geotechnical engineering exploration for the Serrano Water District Wells 3 and 5 PFAS Treatment Plant.
<br />Explored the subsurface conditions at the well site in order to provide geotechnical recommendations to aid in
<br />design and construction of the project. The project included six 12-foot diameter GAC vessels supported on a
<br />concrete pad. Other improvements include the associated piping and site paving.
<br />Project Engineer for a PFAS treatment facility that
<br />includes four 12-foot diameter, ion -exchange (IX) vessels supported on a concrete pad and a pre -filtration
<br />system. Drilled and sampled two exploratory borings to a depth of 261/2 feet. Provided geotechnical
<br />recommendations for the project and prepared a report presenting the findings, conclusions, and
<br />recommendations. Provided geotechnical and special inspection and testing services during construction.
