SERVICE 03 / AS-BUILT & VERIFICATION
As-built and verification surveys measure positions, levels, dimensions or completed works as they exist on site—not as the drawing says they should exist.
We report what is on the ground, not what everyone hoped would be there.
During construction, before work is covered, at practical completion or when reliable records are needed for design changes, handover or future work.
The check is defined against the project requirement. It may compare measured coordinates, elevations, alignments or dimensions with design information supplied by the client.
Where no design comparison is requested, the work can be recorded as an independent measured as-built.
Send the latest design information, the items to be checked, the required tolerances or acceptance criteria, the site datum or control information, and the format expected by the project team.
“Check if it is right” is a question. The drawings and acceptance criteria make it a survey scope.
REAL PROJECT DATA // VERIFY THE DIFFERENCE
The overlay makes the verification problem visible: the design describes intent; the surveyed site records what exists. As-built work connects those two records so positions, levels and completed elements can be assessed against the information the project team is working from.
Completion is not proof of position. Measurement is.
DON'T WAIT UNTIL IT IS COVERED.
