As-built CAD updates from verified site mark-ups

We update CAD from your verified site records and mark-ups. The contractor remains responsible for confirming that those records accurately describe the installation.

Upload a drawing and request an estimate ↗

Prepare the record

Identify drawing number, installed routing, equipment references, sizes, levels and the required record-drawing status. Include marked changes and any supporting sections.

Maintain an issue trail

Each task retains its supplied pack, queries, checked output and released revision. Superseded project references remain traceable.

How the drawing moves forward

  1. Upload the matching CAD, marked-up PDF and project references.
  2. Review the estimate and accept the confirmed scope.
  3. Track drafting and respond to logged queries online.
  4. Review the checked proof, approve it and pay before final release.

Questions before you upload

Does drafting constitute a site survey?

No. A site survey or verification of hidden services is outside ordinary CAD production and would need a separate agreement.
