Produce design calculations, geotechnical reports, specifications, and drawings covering a range of projects from new construction, modifications, and rehabilitation to existing underground facilities and refurbishment. Prepare subsurface investigation programs for the underground structures such as shafts, tunnels, caverns, and ancillary structures. Assist in geotechnical field investigations for tunnel/underground construction projects to support project design development involving design reports, design calculations and drawings. This duty includes field oversight of third-party specialty drilling subcontractors during drilling operations, oversight of testing such as standard penetration tests, cone penetration tests, slug tests, packer tests and other similar applications. Prepare detailed field records, geotechnical soil boring logs, field notes and a final geotechnical exploration report. Perform design services during construction including the review of shop drawings and related construction submittals for support of excavation work including shaft and tunnel support. Develop numerical models to support design development for tunnels and related ancillary facilities (numerical models will include Plaxis, SAP2000, DeepEx, and similar software.) Perform assessment of geotechnical parameters associated with the relevant soil and rock units. Perform structural and geotechnical design calculations, including design of the tunnel, shaft and caverns initial supports and final linings of shafts, tunnels, and caverns, including concrete and steel structures.
