Monteith & Sutherland crews work with CRS Tunnelling Canada project team to ensure the microtunnelling of the 1200mm storm sewer at Dixie-QEW is going per design alignment.
Precise traversing, while crawling, bending and crouching, and carrying the survey equipment all the way to the heading in and back to the portal is a very demanding task. Our crews do an outstanding job, delivering excellent surveys data sets, and performing all tasks in a safe manner.
Last month Monteith & Sutherland have teamed-up with PipeFlo and performed pre-rehabilitation high definition laser scanning (HDLS) survey of overflow sewer at Barton Street between Weir St North and Fairfield.
The survey was completed with P40 Leica HDL scanner. The data were processed in Leica Cyclone, and cross-sections at 1 metre interval, along with best fit centreline of the structure, were generated in 3D Reshaper:
Thanks PipeFlo for the highest safety practices pertaining the confined space entry, and for all the help during the survey.
From the design of complex geodetic networks through control surveys, gyroscopic verifications, monitoring, hydrographic surveying, detailed topo and HDL Scanning to UAV mapping, at Monteith & Sutherland we have expert personnel and precise equipment to provide trusted results. Monteith & Sutherland: Complete Geospatial Solutions.
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.
Monteith & Sutherland Team is providing tunnel surveying support to CRS-Dibco JV at Mill Woods Double Barrel Trunk Sewer Upgrade Project, Tunnelling Phase, 23 Avenue NW, Edmonton. Our services include precise traversing and TACS guidance system operation, as well as surface settlement monitoring along the tunnelling operations path.
Congratulations to the entire STRABAG team working on the Mid Halton WWTP Effluent Outfall Tunnel.
Yet another accurate and precise breakthrough was made, notably due to tremendous efforts of the project tunnel surveying crew.
At Monteith & Sutherland we are happy to have had contributed to this success by performing numerous gyroscopic surveys, using GYROMAT3000 in order to verify the correctness of the complex underground traverse network spanning over 4 kilometers.
Spot on!
