As-Built & Verification Surveys

We measure what has actually been built and compare it with the required geometry, levels or supplied design information.

Service overview

Verify what was actually built

An as-built survey records the completed or installed geometry at the required construction stage.

Where comparison criteria are supplied, we relate the measured work back to the required positions, levels or design information so the project team has a clear survey record.

Measured as-builtSurveyed positions, levels or geometry of the commissioned completed work.
Design comparisonMeasured information compared with the supplied criteria where verification is part of the brief.
Project recordSurvey data and agreed outputs issued for construction, handover or project records.

Workflow

How we deliver it

We plan the sequence around the project brief, programme and required deliverables.

01

Define verification scope

Confirm the elements, design revision, tolerances and required record.

02

Review control

Confirm the coordinate and level framework used for comparison.

03

Survey completed work

Measure the instructed positions, levels or surfaces.

04

Process

Prepare the as-built geometry and required comparison.

05

Check

Review observations, design revision and output consistency.

06

Issue

Provide CAD, schedules, drawings or comparison records to the agreed format.

Questions

As-Built & Verification Surveys FAQ

What can an as-built survey record?

Depending on the brief, an as-built survey can record positions, levels, linework, surfaces, drainage features, roads, structures and other completed construction elements.

Can the as-built be compared with the design?

Yes. Where the current approved design information and required comparison criteria are supplied, measured geometry can be compared with the relevant project data.
