Based on 24 reviews As-built surveys capture the current conditions of a built environment. These surveys provide detailed measurements of internal and external structures for architects, designers, and engineers to use in modelling, redesign or documentation.
Sonto delivers high-accuracy as-built surveys for commercial, residential and heritage sites. We measure what’s actually there (not just what’s on plan), supporting reliable design outcomes, accurate documentation, and smarter project planning.
We start by confirming what needs to be captured (internal, external, or both), as well as what the data will be used for, such as architectural design, BIM modelling, or documentation of existing conditions.
Using laser scanning, total stations or traditional survey methods, we capture spatial data for all required elements – including walls, floors, fixtures, services, and structures – depending on your scope and detail level.
We process the raw spatial data to produce a clear and accurate digital representation (typically as 2D plans or 3D models) ready for use in design, renovation or facilities management.
We deliver the final plans or models in your preferred format, including DWG, PDF or Revit, ensuring they’re easy to work with for your design or project team.

Contact us for a quoteOur approach to as-built surveys is flexible and precise. Whether you’re designing a retrofit, documenting a heritage site or modelling an internal fit-out, we adapt to your project’s scope and deliver accurate, usable data that supports smarter design outcomes.
Our goal is to make sure that you have the most comprehensive, contextually rich survey datasets at your fingertips to improve the outcomes of your design and construction.
We clarify what needs to be surveyed and how the data will be used yo guarantee you’re provided with exactly what your design team requires.
From traditional survey to laser scanning, our team uses the right tools for your site to measure internal and/or external features.
We clean, process and quality-check the data before translating it into 2D plans, elevations or 3D models.
We supply your plans or models in DWG, PDF, RVT, IFC, or another format, all ready for your team to work with.
As-built surveys document the actual conditions of a building or site — including walls, fixtures, and structural elements — to support design, renovation or compliance. They provide a true-to-life base for modelling, ensuring what’s designed matches what’s already there.
As-built surveys capture existing conditions for design or modelling, often before a building is completed or altered. As-constructed surveys verify that recent construction matches approved plans, supporting compliance, council approvals or asset handover.
We provide as-built surveys for commercial, residential, industrial and heritage buildings — both internal and external. Whether it’s a full building, a specific tenancy, or a fit-out, we tailor the survey to your needs.
Yes. We can deliver data in 2D CAD formats, PDFs, or 3D formats like Revit or IFC, depending on what you need for design, BIM modelling or documentation. Just let us know your preferred format upfront.
Timeframes depend on site size, complexity, and the level of detail required. Smaller internal spaces may take one to two weeks to produce documentation, while larger or multi-level sites may take longer. We’ll confirm timing upfront based on your project needs.
