Monteith & Sutherland have been proud partners of Metrolinx, and provide high precision survey services in challenging conditions. In this particular project – performing differential levelling, total station traverses, gyroscopic verification surveys, and High Definition Laser Scanning for our client.
ECLRT Deformation monitoring at Bayview intersection
On the Eglinton Crosstown Light Rail Transit project we perform precise deformation monitoring, where we survey surface and building settlement points. There are approximately 4250 settlement instruments to be observed at varying frequencies over the course of the project, with 7 survey crews working together to complete daily monitoring tasks where there is active construction. One of the most challenging parts of this work is the traffic management. We work alongside On Track Safety Ltd and Toronto Police to manage the flow and safety of traffic, as well as the workers.
Summer safety gear
A fresh order of safety gear has arrived for the summer work being conducted at Monteith & Sutherland. Brand new hard hards, safety glasses, gloves, vests, and other important safety gear is ready for use by our new staff, especially summer students joining us from the University of Waterloo and York University.
ECLRT Deformation Monitoring
On the Eglinton Crosstown Light Rail Transit project we perform precise deformation monitoring, where we survey surface and building settlement points. There are approximately 4250 settlement instruments to be observed over the course of the project, with 6 survey crews working together to complete daily monitoring tasks where there is active construction. One of the most challenging aspects of this monitoring project is measuring above the Tunnel Boring Machines at night and combating poor lighting and glare from car headlights.
