Scan to BIM Modelling
Scan to BIM services that turn your point cloud into a BIM-ready Revit or ArchiCAD file. Our point cloud modelling services produce architectural, structural and MEP elements at your required Level of Development. No scanning needed if you already have data.
Overview
Scan to BIM Modelling explained
Scan to BIM converts a point cloud into an intelligent 3D model. We trace architectural, structural, and MEP elements from registered scan data into native Revit or ArchiCAD, building parametric objects that carry type, dimension, and material information rather than dumb geometry. This is the deliverable design, coordination, and facilities management teams need: a model where every wall, slab, column, and service can be scheduled, clash-checked, and queried. If you already hold point cloud data from any scanner, no new fieldwork is required.
It is important to be clear about what scan to BIM is and is not. A BIM model is a coordinated, data-rich 3D representation built for downstream analysis. That is a different deliverable from a set of 2D as-built drawings. When you need plans, sections, and elevations drafted in DWG, DXF, or DGN rather than an intelligent model, our point cloud to CAD service is the right fit and is usually faster and lower cost. Many projects use both: CAD drawings for documentation and permits, and a BIM model for design and coordination. We help you pick the right output during scoping.
We model to the Level of Development the project requires. LOD 200 suits feasibility and concept work with generic elements and approximate geometry; LOD 300 carries measured geometry for documentation and coordination; LOD 350 adds connections and interfaces; LOD 400 reaches fabrication-level detail. MEP services visible in the scan, including ductwork, piping from 50mm diameter, cable trays, and major equipment, are modelled and categorised by system. We align naming, worksets, and templates to your BIM execution plan so the model drops straight into your environment.
Quality is verified against the source data. Every completed model is checked against the linked point cloud for accuracy and completeness, clash detection is run, element categorisation is confirmed, and a QA report is issued. Model elements at LOD 300 typically sit within 5 to 10mm of their true position. The point cloud is delivered linked alongside the model so your team can verify any element against the measured reality whenever a critical dimension is in question.
Survey control & accuracy
AHD levels and MGA2020 coordinates
A scan to BIM model inherits the coordinate system of the source point cloud. Where we capture the data, scans are registered to MGA2020 coordinates with levels reduced to the Australian Height Datum (AHD), and a registered surveyor on staff oversees control for design-grade work. Where you supply the point cloud, we model in your existing project coordinates so the BIM file aligns with the rest of your consultant set. The linked point cloud lets your team confirm any element against measured reality.

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 is scan to BIM?
Scan to BIM is the process of turning a point cloud from a 3D laser scanner into an intelligent Revit, ArchiCAD, or IFC model of an existing building. A scanner captures the building as millions of measured points, then our BIM technicians trace walls, floors, columns, structure, and services from that data into parametric objects at your specified Level of Development. The result is a coordinated as-built model that design, coordination, and facilities teams can work in directly, rather than remeasuring the site by hand. As a Brisbane scan to BIM team we deliver across Australia, and we accept point cloud data from any scanner if you already have a scan.
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.
What point cloud modelling services do you provide?
Our point cloud modelling services convert registered scan data into Revit, ArchiCAD, IFC, DWG or PDF outputs. We can model architecture, structure, visible MEP services, facade geometry, roof framing, plant rooms and industrial equipment. The scope is set by LOD, element categories and tolerance so the model matches the decision it needs to support.
What is the difference between scan to BIM and point cloud to CAD?
Scan to BIM produces an intelligent 3D model: walls, floors, columns, and services are modelled as parametric objects in Revit or ArchiCAD, each carrying data such as type, dimensions, and material. Point cloud to CAD produces 2D drawings: plans, sections, and elevations drafted in DWG, DXF, or DGN with lines and layers rather than intelligent objects. Choose scan to BIM when you need a coordinated model for design, clash detection, or facilities management. Choose point cloud to CAD when you need accurate as-built drawings for documentation, permits, or teams working in AutoCAD. If you are unsure which fits your project, our point cloud to CAD service page explains the 2D workflow in detail and we can advise on the best path during scoping.
Industries
Industries we serve with scan to bim modelling
Architecture & Design
Renovation and adaptive reuse projects fail when the starting drawings are wrong. Ceiling heights, structural offsets, and services routes discovered on site blow budgets and programmes. Terrestrial LiDAR captures the building as it exists, so your design team works from measured geometry instead of assumptions.
IndustryConstruction & Developers
Construction teams need reliable as-built geometry before concrete is poured, before services are closed in, and before handover. Legacy drawings are often wrong. Site changes happen daily. A registered point cloud gives the superintendent, engineer, and BIM coordinator one shared reference that matches what is on site today.
IndustryIndustrial & Resources
Industrial sites change constantly: new racking, relocated equipment, added pipe runs, and expansion bays. Outdated P&IDs and layout drawings create safety and maintenance risk. High-definition scanning captures pipes, steel, equipment, and clearances in one visit, giving operations and engineering teams an accurate digital twin.
