Based on 24 reviews Contour and detail surveys capture the precise land elevation, boundaries and site features your design depends on, turning them into data you can design directly against. They’re the difference between designing around what you assume is there and designing around what’s actually there.
Sonto delivers high-quality, survey-grade contour and topographic data built on our innovative 3D scanning technology, which sets the standard for accuracy and efficiency. The result is a complete, accurate picture of your site from day one, so your design holds up against the real levels, the real boundaries and the real constraints – whether you’re designing a renovation, a new build, or a subdivision.
We capture detailed, reliable site information including levels, features, structures and visible services across your site. This gives your design team a clear and dependable foundation, helping reduce assumptions and ensuring your project starts with accurate, real-world data from the outset.
Our surveys are carefully calculated and aligned to cadastral boundary data, not assumed features like fences or walls. This ensures your design is based on true legal boundaries, helping avoid costly errors, redesigns or issues later in planning, approvals or construction.
We understand that projects often stall waiting for survey data. Our streamlined workflows and responsive team allow us to deliver detail surveys quickly, helping your project move into design, planning and approvals without unnecessary delays or extended timeframes.
Our surveys are structured specifically for architects, planners and engineers, ensuring the data is clear, usable and ready for real project workflows. This reduces the risk of redesign, supports smoother approvals, and helps your project progress efficiently from concept through to delivery.

Contact us for a quoteAt Sonto, our approach is to support your design with precise, actionable data that improves design accuracy, removes uncertainty early, and keeps your project moving from the very first step.
Our goal is to put the most complete, context-rich survey of your site in your hands, so every decision you make downstream rests on solid ground.
We carry out a desktop assessment and search of relevant survey information, pre-calculate boundary information and review the available databases to confirm everything we deliver is survey-grade accurate before we set foot on site.
We attend your site and gather precise property data using the right combination of survey total station, GPS, drone and 3D scanning technology for the job. Our systems let us capture more, faster - which is how we keep your project moving without compromising accuracy.
We convert the survey data on AHD datum into clear, easy-to-read contour plans and maps that represent your site in 2D. We also package the data as CAD-ready files that import directly into your design software, so you start designing immediately.
When the job is delivered, we stay available for consultation and to discuss any further project-based questions about the survey as your design develops-as your survey partner, not a supplier who disappears once the file is sent.
We’re on site within two weeks of you accepting your quote, and we typically deliver your plans within five business days of completing the survey. Larger or more complex sites can take longer to capture and process, and we’ll always confirm your timeline up front. This speed is a direct result of our technology and systems – we keep your project moving and take the waiting out of the first step. Our two-week site commitment is subject to our terms and conditions.
No. Our survey work is non-invasive. We use total station, GPS, drone and 3D scanning technology to capture your site quickly and accurately, with no digging, no damage and minimal disruption to anyone on or around the property.
Yes. Because we capture precise, AHD-referenced levels across your site, the data supports flood assessment and informs how your design responds to overland flow and flood-affected levels. It gives you and your engineer an accurate basis for decisions where water matters.
We use a combination of survey total station, GPS, drone and 3D scanning technology, selected to suit each site. This is what lets us capture a denser, more complete dataset than conventional methods, and deliver it faster – accuracy and speed from the same system.
Yes. Our surveys are prepared to survey-grade accuracy on AHD datum and built to support the design, planning and approval requirements your project needs to satisfy. Whether the survey feeds a renovation design or a subdivision approval, the data stands up to scrutiny.
We locate and record visible site features and accessible service information and can incorporate available service records into your survey. Fully locating underground services such as sewers may require additional service-location work, which we can advise on for your specific site.
They overlap closely. A topographic survey captures the shape and features of the land, and contour lines are how that elevation data is represented. A Sonto contour and detail survey delivers both – the topographic detail of your site and the contours your design works from – in one dataset.
