  SCST, Inc.

  Feb 2014 - Apr 2016

  Staff Engineer

  • Geotechnical Engineer charged with preparing geotechnical reports, field exploration, In-situ and laboratory soil testing, and construction observation for a variety of civil engineering projects such as underground utilities, roadways, bridges, wharfs, site development, slope stabilization, solar fields, and landfills.• Preparation geotechnical investigative reports: I evaluated field and laboratory data, reviewed available literature and records, and worked with project geologists to identify geologic hazards. Based on the findings I provided recommendations for earthwork and site preparation, deep foundations, shallow foundations, slabs, retaining walls, slope construction, use of geosynthetics, pavement sections (flexible, rigid, and pervious), soil stabilization.• Engineering Analysis Programs used: SLIDE (Slope Stability), Allpile (Pile Analysis), Shaft (Pile Analysis), CPT-IT (Pile Analysis with CPT data), and CLiq (liquefaction analysis with CPT data).• Field Exploration: Hollow stem auger boring and sample collection, cone penetration test (CPT), test pits, evaluation of distressed structures and assessment of existing site conditions including contaminated or potentially contaminated water and soil.• Field Testing: Percolation, double ring infiltrometer (ASTM D3385), sealed double ring infiltrometer testing (ASTM D5093), pile tension and lateral loading, electrical resistivity of soil, and floor level surveys.• Laboratory Testing: common tests for geotechnical properties, and less common testing including; falling head permeability (ASTM D2434), Hydraulic Conductivity (ASTM D5084) , oxidation-reduction potential, soil thermal resistivity, and mix design for lime and cement soil stabilization.• Construction Site Testing and Inspection: Subgrade compaction testing via nuclear density and sand cone, footing bottom inspections, drilled shaft inspections, observation of driven piles, and contaminated soil removal.
