Grant M. Whitaker, EIT

Lakewood, Colorado · On-site & field

• Logged and classified over 180 soil borings and 40 CPT soundings (USCS/AASHTO); supervised standard-penetration and undisturbed sampling on dam, roadway, and commercial sites.
• Performed embankment slope-stability and steady-state seepage analyses (Slide2, SEEP/W) supporting Part 12 dam-safety inspections on two Front Range irrigation reservoirs.
• Designed shallow spread footings and drilled-shaft foundations and authored the geotechnical recommendation sections for 15 project reports under PE review.
• Installed and monitored vibrating-wire piezometers and inclinometers; reduced and trended instrumentation data for a slow-moving cut slope on a state highway.

Denver, Colorado · Internship

• Ran index and strength laboratory testing (Atterberg limits, sieve/hydrometer, direct shear, consolidation) and tied results back to field logs.
• Drafted boring location plans and subsurface profiles in Civil 3D and gINT for a water-treatment-plant expansion.

Golden, Colorado · Geotechnical Engineering Group

• Thesis: transient seepage and internal-erosion susceptibility of zoned embankment dams under rapid-drawdown loading; calibrated numerical models against instrumented field data.
• Supported an undergraduate soil-mechanics lab as a teaching assistant for four semesters.

Golden, Colorado · Thesis: embankment seepage & internal erosion

Golden, Colorado · Tau Beta Pi · Geo-Institute student chapter officer

• Steady-state and transient seepage modeling of a 42-ft zoned embankment; evaluated phreatic surface and exit gradients against internal-erosion screening criteria.

• Back-analyzed a marginally stable clay-shale cut, sized a toe buttress and horizontal drains, and stood up an inclinometer and piezometer monitoring program.

• Subsurface exploration, settlement analysis, and drilled-shaft recommendations for structures bearing on variable weathered-bedrock profiles.
