Understanding Verification
Checking what is being built against the project information.
Construction activities develop in stages, and some positions or interfaces can become difficult to adjust once later work has progressed.
Survey verification provides recorded checks at appropriate stages so that positions, levels and relevant interfaces can be reviewed before or after key construction activities.
The exact verification requirements depend on the project and agreed scope.
Why It Matters
Survey checks at the right stage help avoid problems later.
Detect Issues Earlier
Survey checks at appropriate stages can help identify differences before later work makes them harder to address.
Confirm Position
Checks can confirm that relevant positions correspond with the applicable project information.
Confirm Levels
Level checks can confirm relevant levels at defined stages of construction, where required.
Maintain Quality Records
Recorded survey checks can support quality documentation and later project close-out.
Before Concrete
Checking critical interfaces before they become fixed.
Where required by the project, pre-pour survey checks can support confirmation of the position and level of relevant foundation components before concrete placement.
Depending on the project, examples may include:
- Stubs
- Templates
- Structural interfaces
- Cast-in items
- Relevant reference positions
Not every project includes all of these items; the checks required are agreed for each project.
After Concrete
Recording the completed position after construction.
Post-pour survey checks can provide a record of relevant completed positions and levels after concrete placement.
This information can support quality records, engineering review and later project close-out.
What AI Engineering Does
A clear, recorded process at each verification stage.
Depending on the agreed scope, AI Engineering can carry out survey verification at the construction stages defined for the project.
Review Verification Requirements
Confirm which checks are required, at which stages and against which project information.
Confirm Survey Reference
Confirm the survey control and reference information to be used for the checks.
Carry Out Required Checks
Carry out the agreed survey checks at the relevant stage of construction.
Record Positions / Levels
Record the measured positions, levels and other required information.
Compare with Relevant Project Information
Compare the recorded information with the relevant drawings or project requirements.
Retain Information for Quality & Close-Out
Keep verification information available for quality records and project close-out.
Where It Fits in Construction
Verification takes place as construction progresses.
- Project Information
- Survey Control
- Construction Setting Out
- Construction Verification
- As-Built Records
Project Outputs
Recorded checks that support quality and engineering review.
Verification requirements and outputs depend on the project and the agreed scope.
