ACCIONA is a global leader in sustainable infrastructure and renewable energy, delivering innovative, forward-thinking solutions in over 40 countries. We’re proud to be shaping some of the most complex and transformative infrastructure projects in North America.
In partnership with Metrolinx, ACCIONA is playing a key role in the design and construction of the Eglinton Crosstown West Extension (ECWE), a 9.2-kilometre westward addition to Toronto’s Line 5 light rail transit network. This major infrastructure project includes seven new stations and installation of rail and systems under a progressive design-build model.
Beyond its technical scope, the ECWE project represents a significant investment in sustainable urban mobility, expected to reduce greenhouse gas emissions by up to 5,800 tonnes annually and eliminate over 6.5 million vehicle trips each year when combined with the full Line 5.
This is a unique opportunity to join a dynamic, multidisciplinary team on a complex, high-value project that supports long‑term regional growth and environmental sustainability.
The Geotechnical Technical Coordinator will support the technical and construction delivery of geotechnical instrumentation and monitoring activities across the ECWE SRS project.
Reporting to the Technical Design Manager, the Geotechnical Instrumentation & Monitoring (I&M) Technical Lead will be responsible for the technical oversight, planning, coordination, and management of all geotechnical instrumentation and monitoring activities associated with underground construction works, deep excavations, retaining structures, tunnels, shafts, portals, stations, guideways, and other project infrastructure.
The position will serve as the subject matter expert for geotechnical instrumentation and monitoring and construction impact assessment, ensuring instrumentation and monitoring programs are planned, implemented, interpreted, and managed in accordance with project requirements, applicable standards, and contractual obligations.
Job Description
Lead the planning, development, procurement, implementation, and management of all geotechnical instrumentation and monitoring (I&M) programs across stations, tunnels, shafts, caverns, portals, tail tracks, retaining structures, foundations, guideways, utilities, and other project infrastructure.
Serve as the technical authority for instrumentation and monitoring activities, ensuring compliance with project requirements, industry standards, contractual obligations, and best practices.
Review and coordinate Geotechnical Instrumentation and Monitoring Plans (GIMPs), Construction Impact Assessment Reports (CIARs), Geotechnical Design Reports (GDRs), Hydrogeological Reports, Impact Mitigation Plans (IMPs), SOE and SEM reports/designs, temporary works designs, and other technical submissions to ensure monitoring requirements are adequately incorporated.
Establish monitoring strategies, instrumentation requirements, trigger levels, action response plans, alarm thresholds, monitoring frequencies, and escalation procedures based on project risks and design assumptions.
Ensure instrumentation and monitoring requirements are effectively integrated into multidisciplinary designs and construction activities, including excavation support systems, tunnels, stations, shafts, caverns, foundations, utilities, groundwater control systems, and temporary works.
Lead the review, acceptance, and technical oversight of instrumentation layouts, installation methodologies, monitoring specifications, contractor submissions, and monitoring‑related technical deliverables.
Oversee the installation, commissioning, operation, maintenance, verification, troubleshooting, and decommissioning of all monitoring systems and instrumentation.
Direct and coordinate monitoring programs involving settlement monitoring, ground movement monitoring, inclinometers, piezometers, MPBXs, vibration monitoring, structural monitoring, groundwater monitoring systems, automated total stations, prism monitoring systems, and other automated monitoring technologies.
Review, interpret, and evaluate monitoring data to assess ground behavior, excavation performance, structural response, groundwater conditions, construction impacts, and overall geotechnical performance.
Identify trends, anomalies, instrument issues, and potential geotechnical risks, and lead investigations of trigger‑level exceedances, unexpected movements, excessive settlement, deformation, groundwater impacts, and other performance concerns.
Provide technical support during geotechnical investigations, excavation works, tunnelling, SEM construction, shaft and cavern excavation, foundation installations, earthworks, groundwater control activities, and temporary works implementation.
Lead the technical assessment of monitoring‑related risks encountered prior, during, and post construction.
Collaborate closely with designers, consultants, subcontractors, survey teams, instrumentation providers, construction management teams, and project stakeholders to ensure effective coordination and timely resolution of technical issues.
Support project risk management activities by identifying, assessing, tracking, and mitigating geotechnical and construction risks related to ground conditions, excavation stability, tunnelling, foundations, groundwater, adjacent structures, utilities, and construction activities.
Manage monitoring‑related budgets, forecasts, resources, procurement activities, subcontractors, and contractor performance to ensure successful project delivery and efficient utilization of resources.
Review and approve monitoring reports, technical assessments, risk evaluations, dashboards, presentations, and management updates, while maintaining monitoring records, action logs, risk registers, and technical documentation.
Support Progressive Design‑Build activities by integrating field observations, monitoring results, construction experience, and lessons learned into design development, risk mitigation, and construction decision‑making.
Provide regular technical updates and recommendations to the Technical Manager and project leadership regarding monitoring performance, construction impacts, emerging risks, and mitigation measures.
Lead monitoring program closeout activities, including final performance assessments, monitoring data compilation, as‑built documentation, lessons learned, and resolution of outstanding geotechnical and instrumentation‑related matters.
Ensure compliance with project health, safety, environmental, and quality requirements, and immediately report or escalation unsafe conditions, differing site conditions, and significant geotechnical risks.
Comply with all TRP and project‑specific health, safety, and environmental requirements, including completion of mandatory training, site orientations, toolbox talks, and hazard assessments.
