As-Built & Works As Executed Survey Services in Sydney
Verified Construction. Certified Compliance.
At Astra Spatial, we provide as-built and works as executed (WAE) surveys in Sydney that document the final constructed position of buildings and infrastructure. These plans verify that the completed work matches the approved design and regulatory requirements.
Operating across Sydney and Greater Sydney, our licensed surveyors use robotic total stations to capture precise spatial data for council, engineering, and asset handover documentation.
Why As-Built & WAE Surveys Matter in Sydney
An as-built survey in Sydney confirms that a structure or infrastructure element was constructed to design specifications and approved plans. Councils, developers, and engineers require WAE plans as part of compliance and asset handover processes.
A certified as-built survey in Sydney helps avoid delays in final approvals, protects builders from disputes, and provides an accurate record of what was constructed for future maintenance or design work.
Our team has delivered as-built and WAE surveys for residential, commercial, and civil projects throughout Sydney and Greater Sydney.
Our Sydney As-Built & WAE Survey Process
1 | Design Review & Scope Confirmation
We assess construction drawings and approval conditions to determine which features require as-built measurement and certification.
2 | Field Data Collection
Our surveyors record the final locations of structures, services and infrastructure using total-station methods to sub-centimetre accuracy.
3 | Data Processing & Validation
Captured data is checked against design plans and control points to verify horizontal and vertical tolerances within approved limits.
4 | Plan Preparation & Compliance Review
Certified as-built plans are prepared for submission to council, engineers or asset owners in CAD and PDF formats.
5 | Delivery & Consultation
Your licensed surveyor reviews findings with you and provides digital files for record-keeping and future design integration.

Frequently Asked Questions
What is an as-built survey?
It records the final constructed positions of buildings, structures, and services to confirm compliance with design plans.
What is a WAE (Works As Executed) survey?
A WAE survey is a certified plan required by councils and engineers to verify that constructed infrastructure matches approved designs.
When is an as-built survey required?
At the end of construction — before final inspection or handover — to certify that all elements were built as approved.
What deliverables will I receive?
PDF plans showing final as-constructed data for council lodgement and record keeping.
Can you integrate data with our engineers’ design files?
Yes. We align all deliverables with your coordinate system for seamless integration into design and BIM models.
