Accuracy on Site. Confidence in Every Build.

At Astra Spatial, we provide construction set-out surveys in Sydney that translate your design drawings into exact on-site positions — ensuring your project is built to plan, on time, and on budget.

Working across Sydney, Griffith, and the Riverina, our licensed surveyors use high-precision robotic total-station instruments to set out building corners, foundations, grid lines, and service alignments to millimetre-level accuracy.

Why Construction Set-Out Surveys Matter in Sydney

A precise set-out survey is the critical link between design and construction. Even small measurement errors can lead to misaligned foundations, delays, or costly rework.

Our construction set-out in Sydney teams work directly with builders, developers, and engineers to ensure every structure and service aligns perfectly with approved plans and council requirements.

We’ve delivered successful set-out projects from residential builds in Sydney’s inner and northern suburbs to large-scale infrastructure and subdivision projects across Griffith and the Riverina.

Our Sydney Construction Set-Out Survey Process

1 | Pre-Survey Brief & Design Review

We review your architectural and engineering drawings, datums, and control points to confirm all required elements are included and correctly referenced.

2 | Establish Survey Control

Our team sets up an accurate network of site control marks using total station observations to ensure consistent reference points across the project.

3 | On-Site Set-Out

We mark building corners, grid lines, service routes, and structure positions on the ground using pegs, nails, or paint depending on site conditions.

4 | Verification & As-Built Check

Before work begins, we perform verification checks against your design coordinates and benchmarks to ensure all points are within design tolerance.

5 | Documentation & Handover

You receive digital set-out plans, mark reports, and coordinate data suitable for builder sign-off, council inspection, or engineering verification.

Frequently Asked Questions

What is a construction set-out survey?
It’s the process of marking on-site the exact positions of structures and features shown in design plans using coordinate data and survey control.

When do I need a set-out survey?
Before any physical work begins — particularly before laying foundations, footings, or service alignments.

What’s included in the service?
We set out all structural and service features, provide a Set Out Sketch, and perform verification checks before construction starts.

Can you work directly with my builder or engineer?
Yes — we coordinate directly with builders, project managers, and engineers to maintain accuracy and schedule alignment.

Do you service regional areas?
Yes. Our field teams regularly deliver construction set-out surveys in Griffith, Wagga Wagga, and the broader Riverina region.
