What Is an As-Built Survey?
An as-built survey (also called a Work as Executed (WAE) survey or as-constructed survey) documents what was actually built on site, compared to what was originally approved. It records the final position, dimensions, and levels of constructed elements: the building footprint, slab levels, retaining walls, drainage infrastructure, and any other works covered by the development consent.

In NSW, as-built surveys form part of the occupation certificate (OC) process under the Environmental Planning and Assessment Act 1979. These are prepared by a Registered Surveyor, a credential governed by the Surveying and Spatial Information Act 2002. The deliverable is a certified survey plan: a scaled, annotated document showing the as-constructed works referenced to the approved consent plans and the survey control network.
An as-built survey is not a building inspection or a compliance certificate. It’s a registered surveyor’s certified record of what exists on the ground.
When Do You Need a Boundary Survey in Sydney?
As-built surveys are required at or near project completion. The most common triggers are:
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.

As-Built Survey FAQs
Do I actually need an as-built survey, or will my certifier accept something else?
For most new residential, commercial, or mixed-use construction in Greater Sydney, a certified WAE plan prepared by a Registered Surveyor is a standard requirement for OC issuance. Some certifiers may accept a surveyor’s report for very minor structures, but for any project with a DA consent, it’s the norm rather than the exception. Confirm with your certifier at the start of the build.
What's the difference between an as-built survey, a Work as Executed (WAE) survey, and a final survey?
They’re the same thing. “Work as Executed” is the terminology used in NSW development consent conditions. “As-built” and “as-constructed” are the industry shorthand for the identical deliverable: a certified survey plan showing what was built versus what was approved.
How much does an as-built survey cost in Sydney?
Cost depends on the scope and scale of the project; a single residential dwelling is priced differently from a multi-unit development or commercial build. Contact C&A for an upfront, itemised quote with no obligation.
Will the survey be accepted by my certifier or council?
C&A’s plans are prepared by Registered Surveyors and meet the standard expected by private certifiers and councils across NSW. If your certifier has specific formatting or content requirements, flag them at booking and we’ll prepare the plan to match.
Can C&A handle the as-built survey if they didn't do the original survey?
Yes. We work from your approved DA plans and development consent documents; no prior relationship with C&A is required. Our surveyors are across Greater Sydney, and we’ll pick up from wherever the project is.
