As-built Surveys for the greater Auckland region - Accurate records of completed works for council sign-off and project completion
When construction differs from the approved plans, or completed infrastructure needs to be formally recorded, an as built survey provides the measured information required for approvals and handover.
At Lamb & Associates, we prepare professional as-built surveys for subdivisions, drainage works, civil infrastructure and development projects across the Auckland region. As-built surveys are commonly needed where constructed works must be checked, documented and submitted as part of Auckland Council or utility approval processes.

As-built surveys for completed construction
- Accurate records of completed works for final approvals
- Professional as built plans for drainage and development projects
- Site visits to confirm as-built works and produce required documentation
Looking after clients across Auckland from Warkworth to Bombay. Enquiries from outside this region are welcome too.
What is an as-built survey?
An as-built survey records the actual position, levels and dimensions of completed works after construction. Rather than showing what was originally designed, it confirms what has been built on site.
This information is used to verify compliance, update records and support final approvals where required.
Why as-built surveys matter
Construction projects can change during the build process due to site conditions, engineering adjustments or practical construction requirements. An as-built survey helps confirm that completed works remain acceptable and accurately records any approved variations.
Accurate as-built information can help:
- support Auckland Council sign-off requirements
- confirm completed works align with approved designs or accepted changes
- provide records for future maintenance or upgrades
- assist engineering certification processes
- help progress subdivision completion and title requirements
How the process works
Our surveyors attend site once the relevant works are complete, or at the stage required for inspection. We measure the finished locations, levels and key dimensions using modern survey equipment, then prepare clear plans and supporting data for submission. Where engineering approval is needed, we can work alongside your engineer, contractor and other consultants to help ensure documentation is complete.
Supporting subdivision completion
For many land development projects, final approvals rely on accurate records of completed infrastructure. As-built surveys can form part of the information needed before certifications are issued and new titles can be progressed. We understand the timing pressures involved and work efficiently to help keep projects moving.
Common projects requiring as-built surveys
We regularly carry out as-built surveys for:
- Subdivision infrastructure
- Stormwater and wastewater drainage
- Manholes, pipelines and service connections
- Retaining walls and earthworks features
- Roading, accessways and civil works
- Private development infrastructure
- Commercial and industrial projects
Where public drainage systems are extended or new assets connect into council networks, accurate as-built information is often essential.
Lamb & Associates understands Auckland development standards, council submission processes and the importance of accurate records at project completion. Our team provides prompt service, reliable survey data and practical support for contractors, engineers and developers. Contact us for professional as-built surveys and clear, accurate plans across the Auckland region.
You need evidence that the constructed works still meet council requirements, especially if changes occurred during construction. An as-built survey provides this documentation.
The survey shows the exact location of physical structures and features as constructed, confirming compliance with the original or amended plans.
Design plans show what was intended to be constructed. As built plans record what was actually built on site, including final positions, levels and dimensions after construction is complete.
Yes. We can review your project stage, explain what survey information may be required, and work alongside your engineer, contractor or consultant team to help keep approvals and completion processes moving smoothly.
As-Built Surveys Summary:
- What: As-built surveys producing drainage and as-built survey plans and reports showing structure locations, for Auckland Council sign-off when consented engineering plans change during construction.
- Where: Looking after clients across Auckland from Warkworth to Bombay. Enquiries from outside this region are welcome.
- Who for: Project owners, developers and contractors needing evidence of as-built works, including public drainage connections, for council approval and engineer sign-off.
