RANDALL GOODE, PE, PRINCIPAL GEOTECHNICAL ENGINEER

Randall founded Strata Design in 2006 and has 30 years of professional engineering consulting practice with primary emphasis in geo/environmental engineering, public works, project management, and construction QA/QC throughout Oregon, Washington and California. He maintains civil engineering licensure in Oregon, Washington and California. He has extensive experience with:

  • civil and geotechnical analysis

  • environmental site design involving construction project management and QA/QC on large

  • multi-faceted public works projects

  • contaminated site remediation

  • stormwater treatment

  • erosion control plans

  • deep foundations and earth structures including micro-piles, soil nails, earthwork and shoring

  • landslide stabilization projects

    Randy is skilled in mapping and design software and engineering analysis programs including AutoCad Civil 3D, Slope/W, LPILE, CONSOL, SNAIL and others as well as utilizing ArcGIS and LiDAR survey point clouds and has developed processes in-house for creating 3D elevation site plan and DTM surfaces for migration into autoCAD software. This provides clients with full access to high precision topographic site survey maps from already existing data, and further serves as the most effective tool for interpretations of slopes geomorphology and hazards. These skills are used to design civil grading and earthwork plans.

 

DENNIS ELTON, PE, GEOTECHNICAL ENGINEER

Dennis has over 30 years of experience at seven different firms in Washington and Oregon ranging across geotechnical, environmental and construction. He has demonstrated in client relations, project literature research, field work, construction monitoring, laboratory testing, written communications and reports as well as technical analysis and business operations. He is experienced with footing subgrades, slope setbacks, retaining wall construction, excavations, fill placement, roadway subgrade and base rock (observed proof rolls) and deep foundation pile installation (circular and H section steel), soil investigations, stability analysis for both residential and commercial projects.

KELLY GOODE, MS, GENERAL MANAGER

Kelly has been involved with Strata Design since 2012 and joined Strata officially in 2023 as General Manager. She brings with her 26 years of management and human resources experience with local technology companies. Kelly holds a Master of Science degree in Leadership and Policy with certifications in Erosion Control (CESCL) Inspections, Instructional System Design, Cloud Computing and Change Management. Kelly is proficient in technical project management, software training, people management, and human resources. Kelly provides support in customer service, office administration, website/social media, bookkeeping, human resources and erosion control inspections.

RICK THRALL, PHD, PE, GE, SENIOR GEOTECHNICAL ENGINEER

Rick  has over 35 years of geotechnical engineering experience, including the past 30 years’ in Oregon and Washington. Over his career  Dr. Thrall has served as  a project engineer on wide ranging geotechnical work involving commercial, heavy civil, essential facilities and, more recently, residential construction.  As an early project engineer with Cornforth Consultants and Golder Associates, Rick completed projects involving major structures and buildings, bridges, dams, landslides, levees, instrumentation, water supply, pumping facilities, pipelines and, waste facilities for a variety of federal, state, county and city governments.  More recently, a significant portion of Rick's career has been spent as a geotechnical discipline leader. He has been responsible for growing and developing professional groups and projects with Foundation Engineering, AMEC (now AMEC Foster Wheeler), GeoDesign and PBS Engineering & Environmental.

The majority of his recent work includes:

  • evaluating and designing use of materials for fill or select materials

  • evaluation and mitigation of substandard foundation conditions

  • grading evaluations and design

  • slope stability evaluations

  • mitigation and,seismic stability evaluations

 

CORY VAN FOSSON, EI, SENIOR PROJECT ENGINEER
