Service
Scan to BIM Modelling
Send us your point cloud and we model it into a BIM-ready Revit or ArchiCAD file. Our modelling team produces architectural, structural, and MEP elements at your required Level of Development. No scanning needed if you already have data.
Capabilities
What we deliver
- LOD 100: Massing models showing overall building form and spatial relationships
- LOD 200: Generic model elements with approximate geometry (walls, floors, roofs)
- LOD 300: Specific model elements with accurate geometry, dimensions, and orientation
- LOD 350: LOD 300 plus connections, supports, and coordination elements
- LOD 400: Fabrication-ready model elements with exact detailing
- MEP modelling: ductwork, piping, cable trays, and equipment from scan data
- Structural modelling: steel, concrete, and timber frame elements

Our Process
How we work
BIM Execution Plan
We agree on LOD requirements, element categories to model, naming conventions, and file standards. If you have a BIM management plan, we align our deliverables to it.
Scan Data Preparation
Point cloud is registered, cleaned, and sectioned for efficient modelling. The scan data is linked into the Revit/ArchiCAD template as a modelling reference.
Model Creation
Our BIM technicians trace building elements from the point cloud. Walls, floors, columns, doors, windows, and services are modelled to the specified LOD. We use native families where possible and create custom families for non-standard elements.
QA & Delivery
The completed model is checked against the point cloud for accuracy and completeness. We run clash detection, verify element categorisation, and produce a QA report. The model is delivered with linked scan data so your team can verify any element.
FAQs
Common questions
What are LOD levels in scan to BIM?
LOD (Level of Development) defines how much detail and reliability a BIM element carries. LOD 100 is a conceptual massing model showing approximate area and volume. LOD 200 includes generic elements with approximate size, shape, and location. LOD 300 has specific elements modelled to measured dimensions and positions (accurate to the scan data). LOD 350 adds interfaces and connections between elements. LOD 400 includes fabrication-level detail sufficient for manufacturing. Most renovation and facilities management projects require LOD 300. New-build coordination projects may need LOD 350. We quote based on the LOD you specify.
How long does scan to BIM modelling take?
Modelling time depends on building complexity and LOD level. As a guide: a simple commercial floor plate (1,000m2) at LOD 300 takes 5-8 working days for architectural elements. Adding MEP modelling typically doubles the time. A full three-storey commercial building at LOD 300 (architectural + structural) takes 15-25 working days. LOD 200 is roughly 40% faster than LOD 300. Complex heritage buildings with irregular geometry take longer than modern commercial stock. We provide firm timelines with every quote based on the specific building and scope.
Which software do you model in?
Our primary platform is Autodesk Revit (versions 2022 through 2026). We also deliver in ArchiCAD for practices that prefer Graphisoft workflows. For cross-platform interoperability, we export IFC 2x3 or IFC4. Point cloud processing is done in Trimble RealWorks and Autodesk ReCap. We follow your BIM management plan and can work within your established template, family libraries, and naming conventions. If you do not have a BIM template, we use our own standards-compliant template and can hand over the model with full documentation.
Can you model MEP services from scan data?
Yes. We model mechanical, electrical, and plumbing (MEP) services visible in the point cloud. This includes HVAC ductwork, piping (typically 50mm diameter and above), cable trays, conduit routes, and major equipment items. Each element is categorised by system type and sized from the scan data. Note that elements hidden behind walls, above solid ceilings, or within risers cannot be modelled without either scan access to those spaces or reference to existing drawings. We flag assumptions and limitations in the deliverable documentation.
What accuracy can I expect from a scan-to-BIM model?
Model accuracy is bounded by both the scan data accuracy and the modelling methodology. With our Trimble X7 scan data (+/-2mm point accuracy), model elements are typically positioned within 5-10mm of their true location at LOD 300. Wall thicknesses, opening sizes, and structural member dimensions are measured from the point cloud and rounded to the nearest appropriate construction module (e.g., 90mm stud wall, 200mm concrete slab). We report modelling tolerances with every deliverable. For critical dimensions, we recommend verifying against the linked point cloud rather than relying solely on the model.
Do you follow any BIM standards?
We align our modelling to ISO 19650 (information management using BIM), the NATSPEC BIM Guide for Australian projects, and client-specific BIM execution plans where provided. Element naming follows Uniclass 2015 or OmniClass depending on client preference. File structure, workset organisation, and view templates follow Autodesk best practice guidelines. For government projects, we comply with the relevant authority BIM requirements (e.g., Queensland Government BIM policy). We issue models with a BIM compliance statement listing the standards and conventions applied.
