On a recent project in Rainy River, 1,800km northwest of Toronto, Monteith & Sutherland established precise elevations along Highway 600 using digital levels and invar rods, and by implementing first order levelling procedures. Check out the video below!
Monteith & Sutherland had a fantastic weekend presenting at the University of New Brunswick for the department of Geodesy and Geomatics Engineering. It was a privilege to collaborate with Dr. Robert Kingdon and provide students with a laboratory assignment using our DMT Gyromat 3000, a precision gyroscope used to correct underground traverse orientation.
And not to mention, Dr. Kingdon, along with the outstanding faculty, and our own company president Glenn Dawson (a graduate from the class of ’88), demonstrated why UNB is a world leader in geomatics academia.

Last month Monteith & Sutherland crew performed highly accurate gyroscopic survey using GYROMAT3000 at Nickel Rim South project of Glencore in Sudbury, Ontario, at over 2000 metres underground.
Thanks Glencore team for all the help and safe site conditions which made the work just flawless!

On Thursday March 16, Monteith & Sutherland helped represent the geomatics industry at the industy night organized by the Civil, Environmental and Geological Engineering Society of the University of Waterloo. The evening brought together industry professionals from a variety of firms representing different fields of study within Civil, Environmental and Geological Engineering. We met a lot of students and shared our experiences working on projects alongside Geological/Geotechnical Engineers completing deformation monitoring on various structures to ensure the on-going safety of construction activities. Special thanks to Grant Mitchell, Vice President of the Society, for putting together such a well-organized event.
Monteith & Sutherland has successfully completed the Safety Management Assessment (SMA) certification program developed by the Industrial Education Cooperative, assessed by the Sarnia-Lambton Industrial Educational Cooperative (IEC). The certification is awarded after a 3-year audit process which includes annual reviews of company policies and field visits to observe safety in action. The SMA was created in 2002, and has evolved through a series of revisions to the current integrated audit format, which provides a comprehensive analysis of an organization’s safety management practices. The audit consists of 12 elements that range from legislated safety management requirements to hazard identification and safety management practices in the field. Today more than 250 local, provincial and national contracting companies complete this audit as part of the local industrial plant pre-qualification requirements.
Technician Mark Paddey (pictured above) is documenting survey station parameters and diagramming the vicinity and any obstructions. Monteith & Sutherland established 16 control monuments along a 10km stretch of Highway 600. We used a classical static survey technique to establish our control values over such a large area. The rapid static GNSS technique using our Leica GNSS 1200 receivers can provide accuracies to the order of 1:5,000,000. Using our equipment, the accuracy expectations for horizontal coordinates are 3mm + 0.5ppm and vertical coordinates are 6mm + 0.5ppm, which are unmatchable over large distances with other survey techniques. Mark worked in conjunction with 3 to 4 other staff who established other receivers. Data is recorded on all receivers simultaneously at the same data rate, typically 5 seconds. Observation time for the rapid static campaigns are based on the length between the occupied points and also based on the number of available satellites. At least 4 satellites are required to resolve Latitude, Longitude, Height, and Receiver Time Offset. For this project, we completed two initial 2-hour baseline campaigns followed by shorter observation times on successive campaigns measuring each new point. This allowed us to properly complete the data reduction and post-processing of the satellite data and publish accurate coordinate for these new control monuments.
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 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.
Today, we would like pay tribute to our servicemen and women on our solemn day of remembrance. We want to honour their service and their sacrifice and show that we will never forget their ultimate sacrifice so that we have the opportunity to work in a better world.
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.
