Employer: AECOM Technical Services, Inc.
Job Title: Civil/Geotechnical Engineer
Location: 7595 Technology Way, Suite 200, Denver, CO 80237
Job Code: 4769697
Job Type: Full Time
Duties: Assess and predict mechanisms of ground movements and their effect on overlying structures. Characterize and develop an understanding of advanced aspect of soil behavior through in-situ testing, field monitoring and laboratory testing to undertake quantitative analysis of the data obtained on the field. Understand the background of mechanics and methods of interpretation of SPT, CPT, plate, vane shear and pressure meter in-situ testing techniques. Have an in-depth understanding of how pore water pressures may be measured in the field, considering a range of piezometer designs and a quantitative understanding of potential sources of measurement error such as time lag and gas diffusion. Have a quantitative grasp of the problems encountered in designing and conducting tests, including potential errors in stresses, strains and pore pressures. Apply knowledge on merits and pitfalls of practical applications of sample preparation, specimen reconstitution and apparatus setup on samples collected, including but not limited to triaxial testing, oedometer, ring shear, direct shear, among other procedures. Understand the boundary conditions for analysis imposed by geotechnical testing. Select appropriate strength parameters and soil stiffness in the role of geomorphology based on stress-strain, shear strength, brittle soil behavior and pore water conditions in slope failures. Apply knowledge on the critical state framework of soil behavior, its advantages and limitations. Demonstrate pore water pressure distributions (hydrostatic and seepage related cases) and relate them to effective stresses. Calculate permeabilities from well tests in steady and non-steady state conditions, have an appreciation of permeability in 3 dimensions, and be able to determine flow paths using finite differences. Understand the mechanics of consolidation and be able to predict the time taken for consolidation where drains are used. Distinguish between the various methods of slope stability analysis and apply the appropriate method to assess the stability of slopes under short-term and long-term conditions. Evaluate 1D settlements using elastic solutions. Understand the principles of wave propagation, facets of soil behavior under dynamic loading and apply them in soil slopes under seismic loading and the sliding block methodologies. Evaluate the liquefaction potential using a range of methodologies and understand the mitigation measures. Understand the effect of fabric on the response of consolidated soils, especially in expansive and collapsible soils. Perform a site response analysis using analytical and numerical approaches of earth structures. Perform Elasto-Plastic constitutive models in terms of resulting predictions from finite element analyses. Plan and manage geotechnical works and contract administration. Prepare geotechnical engineering reports and recommendations. Review regulations and standards necessary to conduct technical studies and carry out project design and permitting work. Prepare and/or peer review technical designs, specifications, and construction documents. Assemble and document geotechnical data using software that includes: Excel, Word, Gint, GeoStudio, AutoCAD, and MicroStation. Apply QA/QC requirements to their own work and work of project team. Manage and lead project assignments, including technical, financial, and client satisfaction areas using consistent processes and tools. Perform technical writing including written reports. Provide presentations to clients. Work with planning/evaluation, design and construction teams in regard to tailings dams and water storage dams.
Requirements: Requires a Master’s degree, or foreign equivalent degree in Geotechnical Engineering or Civil Engineering and 4 years of experience in the job offered, or 4 years of experience in tailings dams; and using Excel, Word, Gint, GeoStudio, AutoCAD, and MicroStation.
