As-Built Survey in Sydney

OC applications for new builds: Requirements may vary by project, but for most new builds in Greater Sydney, a development consent will include a condition requiring a certified WAE plan before a principal certifier can issue an occupation certificate.

DA conditions requiring final survey: Some development consents include an explicit condition requiring as-built survey documentation before the certifier can sign off.

Stormwater and drainage compliance: Councils regularly require as-built plans showing the final position and invert levels of drainage works as a condition of consent.

Retaining walls and earthworks: Where retaining structures are part of the approved design, as-built confirmation verifies compliance with the approved engineering drawings.

Knockdown-rebuild and owner-builder projects: If you’ve project-managed your own build, your certifier needs a licensed surveyor to verify the completed structure matches the approved plans before OC can be issued.

Construction variations from the approved design: If the build deviated from consent even marginally, an as-built survey identifies the extent of variation before it becomes a certifier delay.

Site visit by a surveyor: One of C&A’s surveyors attends site and measures the final position, dimensions, and levels of all constructed elements, checked against the approved development consent plans.
