Site monitoring and quality control

Carry out 3D scanning of all structures as they are built.


The worksite for complete reconstruction of the rue Sainte-Catherine infrastructure and roadway in Montréal has been underway since April 2019.

A 3D-scanner survey is carried out from time to time to capture as-built drawings and ensure quality control of the infrastructure assets prior to backfilling. This makes it possible to characterize and index the as-built drawings over a given period, and to track the evolution of the worksite. Conducting a 3D survey makes it possible to compare the initial design with the actual result of the work and carry out point-to-point quality control of the installations. All worksite stakeholders with appropriate authorizations can consult the data on the virtual visit platform.
