As-Built Survey

Accurate As-Built Surveys to Document Completed Construction

As-Built Survey Services

An as-built survey collects and documents completed construction work, verifying the locations, dimensions, and elevations of what was built relative to the approved design. These records confirm compliance, support ongoing operations and maintenance, and provide an accurate account of a finished project.

At ProtechGeo Surveying Ltd., every as-built survey is completed under the supervision of our Principal Alberta Land Surveyor using modern surveying technology. From buildings and roadways to underground utilities and final grades, our team delivers the dependable documentation that owners, engineers, and municipalities rely on once construction is complete.

WHY CHOOSE US?

Our Approach

An as-built is only as good as the access available when it was measured. Underground services measured while the trench is open produce a record you can excavate against. The same services recorded after backfill produce a drawing that is partly measurement and partly assumption. The two cannot be told apart later. We schedule the survey around the stages where the work is still visible.

Recorded Before Covering

Underground work is measured while it is still exposed, so the record rests on measurement.

Same Control as Layout

Work is measured against the control the project was staked from, so a deviation found is a real one.

Deviations Reported

Where the built work differs from design, the difference is documented on the drawing.

Closeout Ready

Deliverables are prepared in the form your municipality or client requires for project acceptance and record submission.

Useful Years Later

Drawings are dimensioned so the people maintaining the site can locate a valve without exploratory excavation.

One Continuous File

The firm that set your control and staked the work is the firm recording it, on one file.

Frequently Asked Questions

Common questions about as-built surveys and construction records in Alberta.
What is an as-built survey?
An as-built survey is a measured record of completed construction. It shows the position, dimensions and elevations of what was built, and how that compares to the approved design.
They confirm the work matches what was approved, and they are usually required for closeout and inspection. Afterwards they are what anyone maintaining the site works from.
Underground work is recorded as it is installed, while the trench is open. Surface and structural work is recorded at completion. Leaving everything to the end produces a weaker record.
An as-built is measured on site by a surveyor. A record drawing is often the design drawing marked up by the contractor. They are not equivalent.
We document the difference. The as-built records what exists on site. Adjusting it to match the drawings would remove the reason for doing it.

Yes. Inverts on mains, manholes and catch basins are recorded, because they determine whether the system drains and are impossible to verify after backfill.
Yes, though we will need the design files and the control the project was built from. Without that reference, deviations cannot be measured meaningfully.
Whatever your municipality or client requires for record submission. Agree the format before the survey starts.
