Record What Has Actually Been Constructed
Measured records of constructed features, compared against design for handover and maintenance.
01Overview
As-built surveying captures the measured position, dimensions or elevations of existing constructed features. The resulting records can be compared with design information or retained for operations and future maintenance.
Accurate as-built records protect owners and contractors alike: they confirm what was delivered, support handover, and give facility managers a dependable reference for renovation, maintenance and future development.

05What to provide
Sharing this information with your request helps us scope the work accurately and respond faster.
- Site location and features to be recorded
- Design drawings for comparison, where verification is required
- Tolerances to verify against
- Access arrangements and site safety requirements
- Preferred drawing formats and layering standards
06Scope limitation
Before you commission this service
Verification is limited to the features and tolerances included in the agreed scope. Hidden or inaccessible features cannot be confirmed through surface measurement alone.
07Common questions
Can you update our existing CAD drawings?
Yes. Digital drawing updates based on measured information are part of our scope, subject to agreed formats and standards.
