Geotechnical  
Instrumentation & Monitoring

Tarra Engineering provides comprehensive instrumentation and monitoring solutions for construction and infrastructure projects, including bridges, tunnels, deep excavations, and high-density urban developments. Our programs integrate precision instruments, real-time data collection, and expert analysis to monitor structural and geotechnical performance throughout the construction process.

Our services include:
  • Geotechnical Instrumentation Monitoring Programs (GIMP): Design and implementation of monitoring programs tailored to project requirements.

  • Structural and Ground Movement Monitoring: Using instruments such as borehole extensometers, inclinometers, crack gauges, shape array accelerometers, vibrating wire piezometers, standpipe piezometers, strain gauges, load cells, tilt meters, fiberoptic sensors, and robotic total stations.
  • Shoring Monitoring: Deployment of inclinometers, survey targets/prisms, strain gauges, and load cells to assess performance.

  • Track Monitoring: Specialized monitoring for railway infrastructure, including Metrolinx, GO Transit, CN, CP Rail, and TTC.

  • Tieback Inspection and Testing: Performance and production testing to ensure compliance and safety.

  • Noise and Vibration Monitoring: Both attended and remote monitoring options available.

  • Vibration Zone of Influence (ZOI) Assessments: Evaluating potential impacts on adjacent structures and infrastructure.

  • Pre- and Post-Construction Condition Surveys: Baseline and follow-up assessments to document existing conditions.

  • Heritage Façade Retention Monitoring: Ensuring the protection and stability of heritage structures during construction.

  • Cloud-Based Data Management: Centralized, accessible platforms for real-time reporting and analysis.

By combining advanced technology with engineering expertise, TARRA delivers monitoring programs that improve safety, support compliance, and provide clients with confidence in their projects.
