Job Description:

Parsons is looking for an amazingly talented Geotechnical Engineer to join our team!

What You’ll Be Doing

• Provide day-to-day geotechnical engineering support to construction teams and site operations.

• Review geotechnical reports, drawings, specifications, soil investigation data, and construction requirements.

• Monitor and verify geotechnical works to ensure compliance with approved design, specifications, and project requirements.

• Provide technical support for excavation, earthworks, grading, embankments, backfilling, compaction, and soil improvement activities.

• Review site conditions and assess the suitability of existing soils and proposed fill materials for construction.

• Monitor excavation activities and identify unsuitable soil, groundwater, weak strata, buried obstructions, or other unforeseen ground conditions.

• Provide recommendations for treatment, removal, replacement, stabilization, or improvement of unsuitable materials.

• Review and provide technical input to Method Statements, Inspection and Test Plans (ITPs), Risk Assessments, and Work Inspection Requests (WIRs) related to geotechnical works.

• Coordinate with QA/QC and approved laboratories regarding soil testing, field density testing, compaction testing, CBR, plate load tests, and other required tests.

• Review and verify laboratory and field test results against project acceptance criteria.

• Monitor earthworks and compaction activities to ensure required levels of density and moisture content are achieved.

• Ensure appropriate testing frequency and locations are maintained and documented.

• Inspect formation levels, subgrade preparation, engineered fill, sub-base, and other earthwork layers prior to subsequent construction activities.

• Provide technical guidance on soil stabilization, ground improvement, dewatering, and excavation support where required.

• Review and assess field conditions where they differ from the approved geotechnical investigation or design assumptions.

• Support the preparation and resolution of Technical Queries (TQs), Requests for Information (RFIs), NCRs, and site technical issues.

• Investigate geotechnical-related NCRs and recommend appropriate corrective and preventive actions.

• Coordinate with Survey teams to verify excavation levels, formation levels, slopes, embankments, and final grades.

• Monitor settlement, ground movement, slope stability, and other geotechnical performance parameters where applicable.

• Provide technical support for temporary and permanent excavation works.

• Review requirements for trench excavation, backfilling, bedding, and reinstatement associated with utilities and infrastructure works.

• Support foundation construction activities by verifying bearing strata and ground conditions prior to concrete placement.

• Coordinate with structural and civil construction teams regarding foundations, retaining structures, culverts, drainage structures, and other below-ground works.

• Review and provide recommendations regarding field changes resulting from actual ground conditions.

• Support construction planning by identifying geotechnical constraints, risks, and required mitigation measures.

• Monitor geotechnical activities against project schedule and identify potential impacts on construction progress.

• Coordinate with subcontractors and specialist geotechnical contractors to ensure compliance with approved requirements.

• Participate in site inspections, technical meetings, progress meetings, and coordination meetings.

• Maintain accurate records of inspections, test results, geotechnical observations, and site conditions.

• Prepare geotechnical technical reports, site observations, material/test summaries, and progress updates as required.

• Support Client and Consultant inspections and respond to technical comments related to geotechnical and earthworks activities.

Airport / Airfield & Infrastructure Responsibilities

• Provide construction support for runway, taxiway, apron, roads, utilities, drainage, and external infrastructure works.

• Monitor airfield earthworks and pavement subgrade preparation in accordance with approved specifications and aviation requirements.

• Verify suitability and compaction of subgrade, capping layers, selected fill, sub-base, and engineered fill.

• Support CBR, density, moisture, plate load, and other field testing activities associated with airfield and infrastructure works.

• Monitor excavation and formation preparation for airfield pavements and major infrastructure facilities.

• Provide technical support for ground improvement and treatment of weak or unsuitable subgrade conditions.

• Review and support construction activities involving embankments, slopes, retaining systems, and other geotechnically sensitive areas.

• Coordinate geotechnical requirements for utility corridors, drainage networks, culverts, foundations, and underground structures.

• Ensure geotechnical risks associated with airport construction activities are identified and managed before and during execution.

• Support investigation and resolution of pavement subgrade failures, settlement, soft spots, excessive moisture, and other ground-related construction issues.

Construction & Field Focus

• Act as the primary geotechnical technical resource supporting site construction activities.

• Conduct regular site inspections and provide immediate technical recommendations for geotechnical issues.

• Review actual ground conditions against geotechnical investigation information and approved construction requirements.

• Ensure construction teams understand geotechnical acceptance criteria before commencing critical activities.

• Provide practical and constructible solutions to ground-related site problems.

• Coordinate closely with Construction Managers, Site Engineers, Supervisors, QA/QC Engineers, Surveyors, and Testing Laboratories.

• Verify that geotechnical works are completed and accepted before proceeding with subsequent construction activities.

• Identify potential construction delays resulting from ground conditions and provide early technical input to project management.

• Support recovery and corrective measures where earthworks or subgrade works fail to meet project requirements.

What Required Skills You’ll Bring

• Bachelor's Degree in Civil Engineering, Geotechnical Engineering, or a related engineering discipline.

• Minimum 10 years of relevant experience, with significant experience in construction and site-based geotechnical engineering.

• Strong experience in major infrastructure, airport, airfield, roads, utilities, earthworks, or large-scale civil construction projects.

• Proven experience in construction supervision, inspection, testing, and resolution of geotechnical site issues.

• Strong knowledge of soil mechanics, earthworks, compaction, foundations, excavation, ground improvement, and construction materials.

• Experience working with geotechnical laboratories and interpreting field and laboratory test results.

• Experience with CBR, FDT, Proctor, plate load testing, soil classification, compaction, and other relevant geotechnical tests.

• Experience reviewing and implementing Method Statements, ITPs, WIRs, RFIs, TQs, NCRs, and technical submissions.

• Good understanding of international geotechnical and construction standards and project specifications.

• Previous airport / airfield construction experience is highly desirable.

Parsons equally employs representation at all job levels no matter the race, color, religion, sex (including pregnancy), national origin, age, disability or genetic information.
