In-House Scan-to-BIM Modelling in Ontario
Turn measured building conditions into a BIM model your project team can use. Geo Vision Surveying Inc captures its own scan data and builds BIM models in-house, with the deliverables and level of detail confirmed at quoting.
Scan-to-BIM Services for Existing Buildings
Planning work in an existing building starts with understanding what is there. Drawings may be incomplete, changes may not have been recorded, and individual measurements may not explain how spaces connect. Scan-to-BIM brings measured conditions into a model, giving your team a shared reference for the agreed areas of the building.
Established in 2024 and based in Hagersville, Geo Vision Surveying Inc provides scan to BIM services in Ontario for architects, engineers, contractors and building owners. We use our own scan data rather than treating capture and modelling as unrelated tasks. Before fieldwork, we discuss what you need to understand, what should be modelled and how the finished information will be used.
What Is Scan-to-BIM?
Scan-to-BIM is the process of capturing an existing building with scanning equipment and using the resulting point cloud to develop a building information model. The scan records visible surfaces. The modelling stage turns the agreed parts of that measured record into a structured representation of the building.
A point cloud and a BIM model are different deliverables. The point cloud is the captured measurement record. The model represents selected features at an agreed level of detail. Not every object visible in a scan needs to become a modelled element, and a detailed-looking model is not a substitute for a clearly defined scope.
Our SLAM LiDAR scanning service covers capture and point-cloud work. This service adds in-house modelling from that data where your project needs it.
When a BIM Model Can Help
An existing-conditions model can support renovation planning, additions and construction documentation. It is useful when several people need to work from the same understanding of an existing space, rather than interpreting separate photographs and handwritten measurements.
Tell us whether you need to understand room arrangements, the relationship between building levels, visible structural features or other accessible elements. We confirm what can be captured and modelled before the work starts. The intended use matters: a model for early planning may need a different scope from one supporting detailed coordination.
Scanning records what can be observed from accessible positions. It does not reveal concealed construction behind walls, floors or ceilings. Areas that cannot be accessed or reliably observed need to be discussed rather than filled in with assumptions.
What's Included
Every quotation defines the capture area and modelling work. Depending on the agreed scope, the process includes:
- Reviewing the project purpose, available drawings and required coverage.
- Agreeing which building elements are to be modelled.
- Planning access and identifying areas that may be concealed or obstructed.
- Capturing the agreed areas with our LiGrip O2 SLAM scanner.
- Processing the captured data and building the model in-house.
- Checking the model against the scan data within the agreed scope.
- Providing the deliverables confirmed in the quotation.
We confirm model requirements, level of detail and delivery formats at quoting. We do not assume that one standard package will suit every building or project team.
How We Approach the Work
First, send the location, the areas to capture and a short explanation of how your team intends to use the model. Existing drawings, photographs and a list of required elements help us understand the request. Tell us who will receive the information and whether the model must relate to other project data.
Next, we agree the scope. We discuss access, coverage, required references, modelling detail and deliverables. Where scanning needs to relate to site control, that requirement is reviewed before capture rather than added after the model has been built.
We then capture and process the agreed areas, using the point cloud as the measurement basis for in-house modelling. Questions about missing access or unclear features are resolved within the agreed scope. At delivery, the model should be used for its stated purpose and alongside any limitations identified for the work.
Combining Building Scans with Site Surveying
A building model does not replace the measurements needed around the building. If your designer also needs ground elevations and visible site features, we can discuss a topographic survey alongside scanning. If the project moves into construction, construction surveying and layout transfers the approved drawings onto the site.
Our Hamilton footing layout project shows a real sequence from a topographic survey in 2025 to excavation and foundation-wall layout in 2026. It is an example of related survey stages, not a Scan-to-BIM case study. We agree each stage separately so the data collected matches the next task.
Where We Work
We work on Ontario projects within about 100–150 km of our Hagersville base, subject to the site address and scope. See our Hagersville, Hamilton and Cambridge service pages for related local surveying work. Send the address so we can confirm availability for your building.
Questions About Scan-to-BIM
Do you build the BIM models in-house?
Yes. Geo Vision Surveying Inc builds BIM models in-house from its own scan data. Capture, modelling requirements and the intended use are discussed together when the work is quoted.
What do I receive?
Your quotation confirms the deliverables, delivery formats and level of detail. Tell us what your project team needs rather than assuming that every visible item will be modelled.
Is a point cloud the same as a BIM model?
No. A point cloud is the captured spatial record. A BIM model represents agreed building elements developed from that record. Your project may need one or both, depending on its purpose.
Can you scan an occupied building?
Clear access helps, but a building does not always need to be empty. We discuss occupancy, obstructions and access arrangements before quoting so the agreed capture area is practical.
Can the model include hidden building elements?
Scanning records visible, accessible surfaces. It does not see through walls or ceilings. Tell us about concealed areas or missing information so limitations can be addressed in the scope.
