Why Use Scan-to-BIM?
Designing alterations, fit-outs, seismic upgrades or plant changes starts with knowing exactly what's already there. Scan-to-BIM captures an existing building with a 3D laser scanner and converts the point cloud into a Revit model, so designers work on real geometry from day one instead of old drawings or tape measurements. It's especially valuable for heritage buildings, occupied sites and plant rooms, where walls are out of plumb, services are congested and access is limited.

What We Model, and to What Level of Detail
Every modelling scope is agreed up front, so you know exactly what you'll receive. A typical LOD 300 Revit model includes:
Architecture: walls, floors, roofs, ceilings, door and window openings, stairs, ramps, handrails and platforms
Structure: columns, beams, steel structures, slabs and bracing
Building services (where required): ducts, pipes and conduits 25 mm and larger, cable trays, electrical panel boards, lighting and major equipment
Site (where required): ground levels, kerbs and paving from survey or drone LiDAR
Usually excluded unless requested: small supports and brackets, fixings, furniture and loose items, flexible pipes and cables, and anything the scanner can't see (laser scanning is line-of-sight).
LOD 200: massing and general layout, for early design and space planning.
LOD 300: accurate size, shape and location of every element. This is our most common level for design and documentation.
Where an object isn't in the standard Revit library, we model it as an in-place element.

3D modelling is a process of creating a digital representation of the physical environment in three dimensions. It involves using surveying techniques and remote sensing technologies, such as LiDAR to collect data on the terrain, objects and features in an area, and then using specialised software to create a detailed 3D model.
Revit 3D modelling creates a digital building model in BIM software, including walls, doors, windows, structure, and optional details like lighting, HVAC, and electrical systems.

Our 3D Modelling Workflow
1. Start with Accurate Reality Capture
Every modelling project begins with reliable site data. We typically use high-definition 3D laser scanning to capture exact physical dimensions and conditions, ensuring a precise foundation for all downstream modelling.
For more detail on how this data is captured, see our 3d laser scanning service.
2. Transform Data into a Usable Model
Captured scan data is processed into a coordinated point cloud and developed into a structured 3D CAD or BIM (Revit) model. This creates a dependable digital representation tailored to your project requirements.
3. Verify As-Built Conditions
With an accurate model in place design teams can verify structure, layout, levels and services against real-world conditions. Helping to identify clashes, irregularities and constraints early in the process.
4. Design with Confidence
Accurate 3D models allow architects, engineers and consultants to design efficiently knowing the model reflects real-world conditions.
5. Improve Coordination & Collaboration
3D models provide a shared reference for all stakeholders, enabling clearer communication, fewer RFIs and smoother interdisciplinary coordination.
6. Reduce Risk, Time & Cost
By eliminating surprises during construction, 3D modelling minimises rework, delays and cost overruns.
7. Reuse the Data for the Future
The model becomes a long-term asset for facility management, future renovations, heritage archiving or structural monitoring.
-
We regularly produce 2D drawings from scans, including elevations and floor plans as they provide an accurate and detailed reference for projects of all complexities.
-
The client defines the level of detail required including any specific instructions and our modellers will adhere to these and complete the project in a timely fashion
-
Revit provides an efficient and streamlined workflow, allowing teams to quickly make changes and updates to the design, reducing the time and effort needed to complete a project. Revit models can be utilised within BIM models
-
Our software enables us to produce ‘walk-through and measure’ tools which permits clients to ‘visit’ the site virtually, without leaving their desk.
-
Some clients prefer to work with the pointclouds themselves, often able to perform design and clash-detection routines (as examples) directly within their own software
-
3D scanning enables the creation of topographic surveys with much more efficiency in situations where access is difficult or significant detail is required.

FAQs
What is Scan-to-BIM?
Scan-to-BIM is the process of 3D laser scanning an existing building and converting the point cloud into an intelligent BIM model, usually in Autodesk Revit. Each wall, floor, beam and pipe becomes a proper Revit element that designers can use for alterations, coordination and documentation.
Which Level of Detail (LOD) Do I Need?
Most design and documentation projects use LOD 300, where each element is modelled at its true size, shape and location. LOD 200 suits early massing and space planning. We’ll recommend a level when we scope your project.
Can You Model From a Point Cloud We Already Have?
Yes. We can turn your existing point cloud into a Revit or CAD model, check the scan data for quality first, and coordinate any extra scanning into the same system.
How Accurate Are Your Scan-to-BIM Models?
Typically ±5–10 mm for architectural models
Sub-centimetre accuracy achievable with survey control
How Long Does Scan-to-BIM Take?
On-site scanning: a few hours to 1 day (size dependent)
