Job Description

About the Project: The Eglinton Crosstown West Extension will bring the Eglinton Crosstown LRT another 9.2 kilometers farther west, creating a continuous rapid transit line from the east end of Toronto into Mississauga. The Stations, Rail, and Systems (SRS) package encompasses the design, construction, integration, and commissioning of key project components.

Position Overview

TRP has a current vacancy for a Geotechnical Technical Coordinator to support the technical delivery and coordination of geotechnical activities across the ECWE SRS project.

Reporting to the Geotechnical & Foundations Technical Lead, the Geotechnical Technical Coordinator will coordinate geotechnical design inputs, investigations, technical reviews, construction support, construction impact assessment, instrumentation and monitoring, geotechnical records, and interfaces between geotechnical consultants, designers, construction teams, subcontractors, and other technical disciplines.

The position will support geotechnical requirements across underground stations, excavations, tunnels, portals, emergency exit buildings, elevated guideway foundations, utility works, temporary works, and other infrastructure within the SRS scope. The successful candidate will have practical experience in geotechnical engineering coordination within major civil infrastructure, transportation, transit, tunnelling, excavation, foundation, or construction projects.

The role requires a robust understanding of geotechnical principles and the ability to translate technical requirements into coordinated constructible solutions.

Key Responsibilities

Coordinate geotechnical, geological, and hydrogeological activities across assigned project work packages and serve as the primary interface between designers,



consultants, construction teams, subcontractors, and project management. Review and coordinate geotechnical, hydrogeological, SOE, SEM, tunnelling, foundation, excavation support, temporary works, and related technical reports, calculations, drawings, specifications, shop drawings, method statements, and technical submissions.

Ensure geotechnical requirements, design assumptions, and risk considerations are effectively integrated into multidisciplinary designs, including stations, tunnels, shafts, portals, caverns, elevated guideways, foundations, utilities, trackwork, and temporary works. Coordinate and review geotechnical investigations, borehole drilling programs, laboratory testing, groundwater assessments, geological mapping, and site characterization activities to support design development and construction.

Review, interpret, and communicate geotechnical investigation findings, including soil and rock conditions, groundwater conditions, laboratory testing results, and subsurface risks to project team. Identify discrepancies between geotechnical assumptions, design documentation, construction methodologies, and observed field conditions, and coordinate development of appropriate technical solutions.

Work closely with multidisciplinary design teams to ensure geotechnical, geological, and hydrogeological requirements are fully integrated into the design of stations,



ancillary facilities, portals, tail tracks, track alignments, structures, and utilities.

Coordinate geotechnical interfaces across all project disciplines, ensuring ground conditions, foundation requirements, excavation constraints, groundwater considerations, and geotechnical risks are appropriately addressed throughout design development, construction planning, and project execution. Provide technical support during excavation, tunnelling, SEM works, shaft and cavern construction, foundation installation, earthworks, dewatering, and temporary works activities.

Review geotechnical aspects of construction methodologies, excavation sequencing, support systems, dewatering strategies, and constructability considerations to optimize safety, schedule, cost, and construction efficiency. Coordinate technical assessment and resolution of differing site conditions, unexpected ground conditions, groundwater issues, settlement, deformation, obstructions, and other geotechnical challenges encountered during construction.

Coordinate geotechnical requirements for deep excavations, support of excavation systems, shoring, bracing, underpinning, anchors, temporary works, and protection of adjacent infrastructure, utilities, roadways, and structures. Support technical coordination of foundation systems, including piles, caissons, drilled shafts, retaining structures, elevated guideway foundations, and associated testing and verification programs.

Coordinate groundwater management, hydrogeological assessments, dewatering activities, and groundwater control measures, and evaluate their impacts on excavation performance, settlement, temporary works, and permanent structures. Coordinate geotechni
