Construction and Topographic Surveying in Caledonia

Geo Vision Surveying Inc works with Caledonia homeowners, builders, designers and contractors from Hagersville, south of town on Highway 6. Our role changes with the stage of the job: ground and building information before design, marks for the excavation and forming crews once drawings are approved, and checks of completed work before it is covered. Telling us which of these you need keeps the quote focused.

Caledonia and Haldimand County

Caledonia is within Haldimand County, which handles the building-permit guidance discussed below. For work closer to our base, see our Hagersville service page. Send the site address, including whether the work is in town or outside it, so we can confirm the responsible municipality and access arrangements.

Caledonia grew up where the old Hamilton to Port Dover plank road, now Highway 6, crossed the Grand River, and the town sits on both banks with Argyle Street as its main north-south street. The nine-span concrete arch bridge built on Argyle Street in 1927 still links the two sides. Tell us which side of the river your site is on and how close a vehicle can get to the work area.

Surveying Caledonia projects: the services we provide

Topographic information before design

Measured ground elevations, buildings, driveways, trees and other visible features from a topographic survey show your designer the lot as it is today, which can differ from an older drawing. For an addition, we agree how far beyond the house the survey needs to reach.

Building and foundation layout

After approval, building and foundation layout marks the building position, the excavation offsets and the foundation corners. We talk through the dig and pour schedule with your crew so each set of marks arrives when it can be used, not days before it gets disturbed. Wider support across the build sits under our construction surveying service.

Grading measurements and as-builts

Grading surveys measure the existing ground and the finished surface so the project team can compare both with the supplied design. As-built surveys document foundations, services or site features before backfill or the next stage. We supply the numbers; grading and drainage design remain with your engineer or designer.

Scanning and other construction measurements

Inside an existing building, SLAM LiDAR scanning records the accessible surfaces, and where agreed we develop BIM models in-house from our own scan data. Repeat monitoring readings, elevation verification and progress measurements are available too, each written into the quotation only when the drawings and project call for it.

Haldimand County building-permit context

Haldimand County's permit guidance lists additions and alterations, new residential construction and certain foundation work among projects requiring a permit. That does not mean every project needs the same survey. Your designer and the County can confirm which measurements and drawings your project needs.

We provide the agreed field information and construction marks. Your designer handles the design, while the County reviews the application and carries out required inspections.
