AECOM has an immediate opening for a Geotechnical Engineer, Civil Engineer, or Geologist in our Portland, Oregon office. The appropriately qualified candidate will be expected to work successfully within a team environment and be able to communicate effectively with other project team members and clients. They will have a high level of initiative, motivation, and display drive, energy, and enthusiasm for getting things done. They will be a critical thinker and problem solver, and ready to apply their knowledge to establish a rewarding, long-term career.  They will be expected to support in the delivery of geotechnical and trenchless design services to internal and external customers within the water, transportation, and environment business lines.

The qualified candidate’s initial assignment will include full-time observation for a large construction project in downtown Portland, Oregon. The duration of the project and initial assignment is approximately 18 to 24 months. The project includes a 3,000-foot-long trenchless crossing under the Willamette River using Horizontal Directional Drilling (HDD) method, four onshore trenchless crossings consisting of horizontal auger boring and pilot tube guide boring, shaft and pit temporary excavation support, and nearly 4,000 linear feet of open-cut trenching.

Following completion of the initial construction assignment, the successful candidate will primarily assist AECOM’s Pacific Northwest geotechnical team (Portland, OR and Seattle, WA offices) on a variety of field and office projects. Projects may involve traditional geotechnical work, such as site investigations, soil laboratory testing interpretations, geotechnical analyses and calculations, and geotechnical reporting and recommendations. Projects may also include detailed design work (e.g., drawings, specifications, cost estimates) for trenchless, geo-civil, and/or geo-structural projects. The successful candidate will also have opportunities to support other offices in the West region and across the nation remotely and/or on site.

The responsibilities of the position include, but are not limited to:

Initial full-time construction observation assignment (18-24 months):

  • Observe trenchless and open-cut construction activities, and prepare detailed daily field activity reports in a timely manner for circulation within the project team.
  • Attendance at regularly scheduled construction progress meetings.
  • Regular communication with project manager, project engineer, contractor, and client.
  • Proactively communicate issues or potential issues to project engineer.
  • Coordinate with subcontract materials testing laboratory to schedule testing, and observe field construction materials testing for soils and concrete.
  • Collect and interpret readings from geotechnical/environmental instrumentation (vibration monitoring, inclinometers, tiltmeters, crack meters, noise) for review by senior engineer.
  • Coordinate with subcontract surveyor to collect and interpret readings from conventional deformation survey monitoring points.
  • Continuously expand and update professional knowledge, and hone training skills to enhance individual and team performance.

Subsequent assignments:

  • Learn from Senior Geotechnical Engineers, Geologists, and Civil Engineers to expand knowledge and skill set.
  • Assist in geotechnical services for various types of projects such as tunnels and trenchless installations, dams and levees, highways, retaining walls and temporary shoring, shallow and deep foundations, pipelines, pavements, embankments and natural slopes, dewatering, landslides, seismic hazard analysis, and environmental remediation.

  • Assist in procurement of subcontract drilling and laboratory testing services.
  • Prepare project-specific Health and Safety Plans and site investigation plans.
  • Perform field supervision for site investigations and testing (soil borings, rock coring, CPT, test pits, geophysical survey, geologic mapping, packer testing, borehole permeability, etc.).
  • Supervise installation of geotechnical instrumentation and assist in data collection and interpretation (piezometers, inclinometers, structural deformation).
  • Prepare laboratory test assignments and interpret test results.
  • Develop material parameters for soil and rock.
  • Perform geotechnical calculations evaluating soil liquefaction, seismic deformation, slope stability, seepage, bearing capacity, settlement, axial and lateral pile capacity, dewatering, lateral earth pressures, retaining wall stability calculations (soil nail, MSE, tieback, sheetpile), and pavements design.
  • Assist in preparation of reports, drawings, specifications, cost estimates, alternatives analyses, and other project documents.
  • Perform construction phase services such as field quality assurance inspections such as monitoring installation of foundations and earthwork, field testing, and assisting in construction administration tasks such as review of contractor submittals and RFIs.
