Dixie-QEW, Microtunnelling, Surveying

Featured Project: Microtunnel alignment surveys, Dixie-QEW Storm Sewer

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.

Featured Project: Pre-rehabilitation HDLS survey of overflow sewer

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.

Mid Halton Outfall Tunnel

Mid Halton WWTP Effluent Outfall Tunnel Breakthrough

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!
