  • Help prepare documentation for daily shift handovers, summarizing progress, critical notes, and tasks related to the excavation of large caverns. 
  • Contribute to the daily excavation plans, adjusting as needed to maintain efficiency and safety across the sizable work areas. 
  • Support the Shift Engineer in identifying and addressing technical challenges that arise in the excavation and lining of the large caverns. 
  • Contribute to reports and suggestions for continuous improvement, particularly in the context of large-scale tunneling and underground cavern construction. 
  • Act as a point of contact for site workers within the tunnel environment, facilitating clear communication between the Shift Engineer, supervisors, and on-site teams. 
  • Attend shift handover meetings, ensuring accurate relaying of information and addressing any issues related to working in the 150-meter-long, 23-meter-wide underground caverns.


  • Bachelor’s degree in Civil Engineering, Mining Engineering, Geotechnical Engineering, or a related field. 
  • Basic understanding of tunneling and underground construction principles, with an eagerness to learn in a high-impact role. 
  • Strong communication skills to work effectively within a multidisciplinary team in confined, challenging underground spaces. 
  • Ability to work under pressure in physically demanding conditions.
  • Proficiency in MS Office Suite; familiarity with AutoCAD and other relevant software is a plus. 
  • Detail-oriented with a commitment to upholding strict safety and quality standards. 
  • Familiarity with Ontario and Federal environmental regulations.
  • Prior internship or co-op experience in large construction projects (transportation), is advantageous.
