Project Overview
Introduction
In the summer of 2021, the Yukon Southern Lakes Region faced record-breaking flooding. As a proactive safety measure, the City of Whitehorse called on Underhill Geomatics to assess the structural stability of the Robert Campbell Bridge during the high-water event.
Project Challenges
The key challenge was ensuring timely deployment and accurate real-time monitoring while flood conditions evolved rapidly. The work demanded immediate action, high-precision technology, and reliable data to inform public safety decisions.
Underhill’s Approach
Underhill rapidly installed a real-time monitoring system combining traditional survey prisms with advanced Senceive tilt sensors. The system provided continuous structural data and real-time updates to city engineers and emergency response teams. UAVs were also used to assist with situational awareness and access.
Notable Outcomes
- Monitoring confirmed no deformation or displacement of the bridge structure
- Real-time data helped maintain public safety and operational confidence
- Successful integration of sensor technology with traditional surveying methods
- Strong collaboration with municipal teams during an emergency response
Technical Highlights
- Real-time structural monitoring using Senceive tilt sensors
- Traditional prism-based survey control
- UAV deployment for rapid site assessment
- Data collection and analysis under emergency flood conditions
- Zero measurable structural movement detected
- Immediate reporting to municipal stakeholders
Project Impact
Underhill’s rapid deployment of real-time monitoring systems helped protect critical infrastructure during one of Yukon’s most severe flood events. By combining tilt sensors, survey prisms, and UAV data, we delivered clear, actionable insights that supported public safety and emergency response. The project demonstrated how technology and trust can work together to safeguard communities under pressure.
