3D Settlement Monitoring in the Sea to Sky
Professional 3D Settlement Monitoring in the the Sea to Sky, deploying millimeter-accurate monitoring networks to track structural shifts, shoring deflections, and ground subsidence throughout construction phases.
In the Sea to Sky, 3D settlement monitoring is required to track structural stability, deep excavations, and adjacent properties. 3D settlement monitoring surveys are processes designed to identify and track the minute movement of construction elements over time, including slope stability, ground settlement, and structural deformation. In British Columbia, determining the location of any natural or artificial feature relative to a boundary for the purpose of certifying it in writing is exclusively defined as the "practice of land surveying" under the Land Surveyors Act. Engaging a commissioned British Columbia Land Surveyor (BCLS) ensures your monitoring program possesses the statutory authority and geomatics precision required to protect the project.
Long-term monitoring surveys require a systematic approach to collecting the information necessary to derive the exact differences between one set of monitoring data and the next. To achieve the accuracy tolerances demanded by geotechnical and structural engineers, our firm deploys an survey equipment. We establish a primary geodetic control network using Static GNSS and RTK GNSS Receivers. Because the foundation of any monitoring program is the accuracy and stability of its control network, our survey crews deploy high-precision Robotic Total Stations to run closed-loop traverses to secure the site. When structural monitoring is required, we utilize Terrestrial 3D Laser Scanning to capture high-density point clouds of the as-built conditions, opening up geometric analysis for rockfaces, complex structures, and inaccessible terrain. Unmanned Aerial Systems (UAS) equipped with Aerial Drone LiDAR and photogrammetry can also be deployed to model expansive slopes and terrain changes over time.

Our 3D Settlement Monitoring Process in the Sea to Sky
How do we ensure accuracy and efficiency in our land surveying projects?
Research:
The foundation of a monitoring program is documentary research, studying the proposed designs, liaison with other professionals and pre-planning. The BCLS accesses the the the Sea to Sky Geographic Information System (GIS) to ensure control points can be established. We evaluate the proposed design and collaborate with your engineering team to determine the necessary survey equipment, tolerances, and the required frequency of measurements.
Field Work:
Upon arriving at the site, our survey crews establish the primary control network and install the physical monitoring points. The scope of field work and the time required to complete the survey are heavily impacted by the frequency of the monitoring schedule, the line of sight across the construction zone, and the ruggedness of the terrain. Our surveyors place attention on instrument calibration, monitoring methods, and redundancy in measurements to identify and understand any sources of error.
Plan Preparation:
Back in the office, our geomatics technicians translate the precise 3D field data into reporting. The BCLS analyzes the results to ensure reliability. As your certifying professional, the BCLS prepares a representation of the data along with a spreadsheet, which may include graphs showing movement over time or a deformation model showing the differences between two surfaces.
