Parsons is looking for an amazingly talented Senior Geotechnical Engineer to join our team in Qatar! In this role, you will support the supervision of geotechnical, earthworks and soil-improvement activities on a major roads, infrastructure and drainage programme. The works include road and utility infrastructure, deep drainage networks, microtunnelling, pump stations, attenuation tanks, deep structures and associated ground-improvement works.

Supervise and witness geotechnical construction activities on behalf of the Engineer, including ground investigations, boreholes, trial pits, sampling, in-situ testing, laboratory testing, groundwater investigations and geophysical surveys. Review existing and supplementary geotechnical information and assess the Contractor’s proposals for verifying ground conditions across the works. Review and comment on the Contractor’s geotechnical submissions, including Geotechnical Factual Reports, Geotechnical Interpretative Reports, method statements, Inspection and Test Plans, material submittals, risk assessments, monitoring plans and specialist designs.

Supervise ground-improvement works for poor-bearing soils, including sabkha and marine sand, and verify that the Contractor’s proposed treatment methods achieve the specified bearing-capacity, settlement-control and performance requirements. Review the design, trials and execution of ground-improvement techniques, including cut and replacement, rapid impact compaction, dynamic replacement and other approved specialist methods. Witness and evaluate pre-treatment, post-treatment and verification testing, including CPTU, plate-load tests, zone-load tests, C  tests, strength and stiffness testing, compaction-control testing and settlement monitoring.

Review geotechnical and foundation requirements for roads, pavements, embankments, deep manholes, microtunnelling shafts, attenuation tanks, pump stations and other buried or above-ground structures. Monitor groundwater conditions and review the Contractor’s groundwater-monitoring and temporary-dewatering proposals, including instrumentation, settlement monitoring, discharge arrangements and corrective-action procedures. Review changes in encountered ground conditions, assess their effect on the works and provide timely technical recommendations to the Resident Engineer and wider supervision team.

Inspect earthworks, grading, engineered fill placement and compaction, and verify compliance with approved materials, procedures, test frequencies and acceptance criteria. Coordinate geotechnical requirements with the roads, drainage, structural, utilities, materials, environmental, quality and health and safety teams. Liaise with the Contractor, specialist subcontractors, laboratories, designers and relevant authorities to resolve geotechnical issues and secure required technical approvals. Raise and track site observations and Non-Conformance Reports, review proposed corrective actions and verify the satisfactory close-out of geotechnical non-conformances.

Maintain accurate inspection records, testing registers, technical correspondence and geotechnical documentation to support progress reporting, quality records and project handover. Support the review of as-built information and handover records for completed…
