As-Built Surveying Services

Accurate Measurement of What Was Actually Constructed

Construction drawings show what was designed. As-built surveying records what was actually built.

Geo Vision Surveying Inc provides accurate as-built measurements and construction verification for contractors, engineers, developers and project managers throughout Southern Ontario.

We use professional surveying equipment to document the actual location, elevation and dimensions of completed construction features.

WHAT IS AS-BUILT SURVEYING?

An as-built survey documents the actual position and elevation of construction after it has been installed or completed.

These measurements allow contractors, engineers and project teams to compare completed work with the design drawings and identify any differences before the project moves forward.

As-built measurements can be completed during construction or at project completion, depending on the project requirements.

WHAT WE CAN MEASURE

Construction As-Built Measurements

Geo Vision Surveying Inc can provide as-built measurements for a range of construction features, including:

Foundations & Structures

Foundation corners, walls, columns, structural elements and required elevations can be measured to document completed conditions.

Grading & Elevations

Finished grades, site elevations, slopes and drainage features can be measured for comparison with the project design.

Utilities & Site Features

Visible or accessible utilities, manholes, catch basins, curbs, sidewalks, roads and other installed site features can be documented.

Where underground infrastructure requires measurement, surveying should be completed before the features are backfilled or covered.

Construction Verification

Completed construction elements can be checked against the design before the next phase of work begins.

WHY AS-BUILT SURVEYING MATTERS

Verify Construction Before Problems Become Expensive

Accurate as-built measurements provide project teams with reliable information about completed work.

They can help:

• Verify constructed positions and elevations
• Identify differences from the design
• Document completed construction
• Support engineering review
• Reduce the risk of problems being discovered after additional work is completed

When critical construction features will become covered or inaccessible, completing the as-built survey at the correct stage is especially important.

Example: as-built elevation checks on a bridge project in Brantford. Background reading: as-built surveying in Toronto.

OUR PROCESS

1. Send Us the Project Information

Provide the project address, current drawings and a description of what needs to be measured.

2. Confirm the Scope

We confirm the required measurements, deliverables and appropriate timing for the field work.

3. Complete the Field Survey

Our field team measures the required construction features using professional surveying equipment.

4. Deliver the Information

Depending on the project scope, deliverables may include field coordinates, elevations, CAD information, drawings or other project-specific documentation.
