Senior Field Geotechnical Engineer

Location: Clay

Pay Range: $54.35hr - $77.03hr Job Overview:
This position is dedicated to a large-scale semiconductor manufacturing facility project in Clay, New York, involving extensive deep foundation and earthwork construction. The organization is seeking a Senior Field Geotechnical Engineer to provide on-site engineering leadership and supervision for deep foundation and earthwork construction at the site. This role is primarily field-based; the majority of the work will involve on-site supervision of drilled shaft construction socketed into rock and earthwork with ground improvement consisting of over-excavation and replacement with engineered granular fill.

As the senior geotechnical representative in the field, the successful candidate will exercise independent engineering judgment on construction issues as they arise and serve as the principal geotechnical interface with Construction, the Engineer of Record, and the client. The successful candidate will work independently in the field while coordinating closely with Construction, CSAOM, ES&H, and the project management team. Excellent verbal and written communication skills and a commitment to leadership, quality, and safety values are required.

Responsibilities:
The majority of this field-based role involves on-site supervision of drilled shaft construction socketed into rock and earthwork with ground improvement consisting of over-excavation and replacement with engineered granular fill, in accordance with applicable procedures, codes, standards, and contract requirements. Specific tasks will include (but are not limited to):
Provide on-site technical supervision during drilled shaft installation socketed into rock, verifying shaft location, plumbness, diameter, and rock socket length/embedment against the approved drawings and specifications. Verify rock socket conditions including rock type and quality, sidewall roughness, and base cleanout, and coordinate with home-office engineering on any deviations from the design basis. Observe and document reinforcement cage fabrication and placement and concreting operations including tremie placement, concrete mix verification, slump/flow, temperature, and test cylinder preparation.

Review installation logs, concrete delivery tickets, and inspection records for quality and specification compliance. Support and witness drilled shaft load testing programs (static, bi-directional, or dynamic), including verification of equipment calibration, observation of testing, and preliminary review of results. Provide on-site supervision of earthwork and ground improvement consisting of over-excavation of unsuitable material and replacement with engineered granular fill. Verify excavation limits and depths to suitable bearing strata;

inspect and approve exposed subgrade (including proof rolling); and confirm granular fill gradation, placement, lift thickness, moisture conditioning, and compaction against specification. Review field and laboratory test results (density, gradation, moisture content) and coordinate any required remediation with engineering and Construction. Identify construction issues or deviations early and coordinate corrective actions with Construction, subcontractors, and home-office engineering. Maintain field documentation, including daily reports, inspection records, nonconformance reports (NCRs), and quality records.

Track scope of work and schedule; coordinate closely with other technical disciplines as an integrated team. Support the development and implementation of geotechnical investigations and the origination/review of geotechnical engineering designs, specifications, calculations, and reports as needed. Provide technical direction to and mentor less experienced field geotechnical engineers and inspectors assigned to the site. Lead field investigation of drilled shaft and earthwork nonconformances, including evaluation of integrity test results, and recommend corrective actions to the Engineer of Record.
