Original job description

Who We Are:

Scarborough Transit Connect (STC) is a joint venture between Aecon and FCC Canada Ltd. that was selected by Metrolinx to deliver the Scarborough Subway Extension – Stations, Rail and Systems (SSE-SRS) package. The Scarborough Subway Extension will bring the TTC’s Line 2 subway service nearly eight kilometers farther into Scarborough. It will extend from Kennedy Station to Sheppard Avenue and McCowan Road, providing quick and seamless transit for those heading into and out of the downtown core and those travelling within Scarborough. The extension will replace Line 3 (the Scarborough RT), helping to reduce travel times and improve access to jobs, schools, and other key destinations throughout the city.

As part of this project, we are currently looking for a Sequential Excavation Method (SEM) Manager to join our team.

What You Will Do:

Reporting to the Sequential Excavation Method (SEM) Construction Manager, you’ll manage the safe and efficient execution of tunnel construction activities associated with the SEM works.
Lead daily tunnel operations, ensuring work is executed in accordance with project requirements, approved methodologies, schedule commitments and quality standards.
Monitor tunnel performance, ground conditions, instrumentation data, and construction progress, escalating risks and concerns as required.
Conduct daily RES meetings, reviewing status of construction activities, face maps, probing results, instrumentation readings and shotcrete test results.
Submit daily RESS to the EoR, documenting the required excavation and support elements discussed at the RES meeting and describing all SEM related activities.
Coordinate field activities between construction crews, subcontractors, engineering, survey, quality, safety and project controls teams.
Ensure compliance with all geotechnical, engineering, environmental, and safety requirements throughout tunnel construction operations.
Work closely with Engineering teams to address field issues, design changes, RFIs, and emerging ground conditions.
Support schedule development and short-interval planning activities to ensure tunnel works remain aligned with project milestones.
Foster a strong safety culture and ensure all work is performed in accordance with company, client, and regulatory requirements.
Participate in stakeholder meetings and provide regular updates on tunnel progress, risks, constraints, and mitigation plans.

Experience You Will Bring:

Degree or diploma in Civil Engineering, Construction Management, Engineering Technology, or a related discipline.
10+ years of experience in SEM construction, including at a minimum two completed projects utilizing SEM in soft ground.
Experience working on major infrastructure projects, including transit, rail, subway, transportation, or other large-scale civil construction projects.
Strong understanding of geotechnical principles, tunnel support systems, ground control measures, and underground construction best practices.
Proven ability to coordinate multidisciplinary teams in a complex and active construction environment.
Strong knowledge of construction planning, scheduling, productivity monitoring, and risk management.
Experience interpreting engineering drawings, geotechnical reports, specifications, and construction procedures.
Strong leadership and communication skills with the ability to build effective relationships with project stakeholders.
Demonstrated ability to make sound decisions and respond effectively to changing site conditions.
Thorough understanding of applicable health and safety regulations and a strong commitment to safety leadership.
Proficiency with Microsoft Office and construction management software platforms.

Why Join Us?

Compensation: $150,000 - $180,000 annually. The listed salary range reflects potential base pay and considers factors such as experience, education, and training. Each candidate is evaluated individually and offers toward the higher end may be extended to those with exceptional qualifications.

Comprehensive health and dental benefits and RRSP matching plans.
The opportunity to work on one of the most exciting rail projects in Toronto.
A wide array of learning and development opportunities.
A work environment focused on health and safety.
