Surveying Services for Every Project

Monteith & Sutherland are recognized experts in tunnel surveying — providing precise alignment control, deformation monitoring, and as-built documentation for underground infrastructure projects. We work with contractors, transit authorities, and municipal engineers to keep tunnelling operations on line and on grade.

Legal surveys produce registered plans, reference plans, and deposited plans that form part of the public land registry. Prepared and signed by licensed Ontario Land Surveyors, these documents are required for severances, easements, and conveyancing.

A boundary survey precisely defines the legal limits of a property by locating and marking corners, lines, and encroachments. Essential for real estate transactions, resolving disputes, and planning any construction near property lines.

Topographic surveys capture the shape of the land — elevations, contours, drainage patterns, and existing features both natural and man-made. The essential data layer for engineering design, site planning, and environmental assessments.

Construction layout translates approved engineering plans into physical markers on the ground, ensuring every structure, road, and utility is built exactly where it's designed to be. We keep your project on grade, on alignment, and on budget.

Gyroscopic surveying uses precision gyroscope instruments to determine true north and establish accurate azimuth control in environments where GPS and conventional methods cannot reach — including underground tunnels, mine shafts, and enclosed structures. Our gyro survey capability is a key part of our underground infrastructure practice.

From initial concept through registered plan of subdivision, we provide full-service surveying support for residential and commercial subdivision applications. We work closely with planners, engineers, and municipal staff to keep your project moving.

Hydrographic surveying maps the underwater features of lakes, rivers, harbours, and coastal areas — measuring water depths, bottom contours, and submerged structures. Our hydrographic surveys support waterfront development, dredging operations, bridge and dock design, and environmental assessments along Ontario's extensive waterways.

High definition 3D laser scanning captures millions of precise measurement points per second, producing a dense point cloud that documents existing conditions with sub-millimetre accuracy. We deploy terrestrial and mobile LiDAR systems for complex structures, heritage buildings, industrial facilities, and infrastructure projects where traditional survey methods are impractical or insufficient.
