Monteith and Sutherland crews worked on a comprehensive survey for the TTC‘s Bloor-Yonge and Pape stations.
Soheil Namdari, pictured above, lead one of the Survey crews completing the control and topographic surveys at Pape Station. The survey crews performed precise traversing and levelling from local City of Toronto control monuments to Pape station. A street-level topopgraphic survey around Pape Station was completed for future planning purposes. We also searched for boundary evidence and completed a cadastral survey to confirm the Pape Station property limits.
At Bloor-Yonge Station project, the crews traversed and levelled from local City of Toronto control monuments to platform level, and then into the tunnels. The control network was then adjusted and used to coordinate the High-Definition Laser Scanning campaign. The challenge of the project has been the time constraints and limited work windows to ensure regular TTC services are not impacted. The use of a HD-scanner was imperative to get big volumes of detailed data as quickly as possible. Our Leica P40 Leica scanner is very quick and of the high precision.
