Feasibility and topographic surveys that give designers a true picture of the ground
Topographic surveys to the level of plans, profiles and contours, as required by international standards for public and private investments. Talk to our team about your site, timeline and the standard your project must meet.
Why feasibility and topographic surveys matters
Every design decision on a road, dam or powerline rests on the ground model underneath it. When levels, features or boundaries are wrong, the error travels into quantities, costs and programmes. A careful topographic survey at feasibility stage removes that risk before money is committed.
Topographic surveys to the level of production of plans, profiles, contours and more, as required by international standards on roads, waterlines, powerlines, dams, building construction, railways, mining sites, oil and gas and the agriculture sector, in public as well as private sector investments.

Our process
Step 1: Scoping and control
We agree the corridor or site extent, accuracy class and deliverables, then establish or extend survey control so every observation ties to the national grid.
Step 2: Field data capture
Our teams pick up levels, natural and built features, utilities and boundaries using total stations and GNSS, at the intervals your design standard requires.
Step 3: Processing and modelling
Observations are adjusted and checked, then processed into digital terrain models, contours, long sections and cross sections.
Step 4: Plans and reporting
You receive plans, profiles and a survey report in the formats your engineers use, with a walk-through of anything unusual on site.
Benefits of working with COGO
Reliable designs
Designers work from verified levels and features, not assumptions.
Accurate quantities
Earthwork and material estimates start from a true ground model.
Standards-ready outputs
Plans, profiles and contours are prepared to the standard the project demands.
“A good design starts with an honest picture of the ground.”
