BIM Modelling
Accurate. Collaborative. Designed for Architects.
Reliable BIM for existing conditions starts well before modelling. It begins with accurate site capture, followed by intentional, well-scoped modelling, and supported by real collaboration with the people creating the model.
At R24, we deliver BIM models for existing buildings using Matterport Pro3 LiDAR capture, professionally modelled by our Australian BIM partner Xtour. The result is a practical, design-ready BIM workflow that Architects can trust.
Why BIM for Existing Conditions Often Falls Short
Many BIM files created from site scans look impressive at first glance, but quickly become frustrating in practice. Common issues include:
Missing architectural elements or services
Metric and imperial measurement inconsistencies
Limited ability to refine or clarify scope
Offshore modelling with no direct access to the modelling team
Files that don’t suit the stage of design
Good BIM isn’t automated — it’s interpreted, scoped, and modelled with intent.
Fast, Accurate Site Capture with Matterport Pro3
We use the Matterport Pro3 LiDAR camera to capture existing buildings quickly and cost-effectively.
Matterport Pro3 provides an excellent foundation for BIM modelling:
Fast site capture - often completed in a single visit
LiDAR-based spatial accuracy - suitable for design-stage modelling
Full visual context - a navigable 3D model alongside the point cloud
Cost-effective data capture - reducing repeat site visits
The Pro3 produces a registered E57 point cloud, with a quoted tolerance of approximately ±20mm, which is suitable for the vast majority of design and existing-conditions use cases.
Matterport is not the BIM - it’s the best possible input to a professional BIM process.
BIM Modelling by Xtour – Local, Collaborative, Design-Focused
Your BIM model is created by Xtour, an Australian-based BIM and 3D modelling team specialising in existing conditions.Large open industrial areas
This local collaboration is where the real value lies.
Instead of uploading data and hoping for the best, Architects and consultants can:
Speak directly with the modelling team
Clarify what matters most in the project
Adjust scope as the design develops
Reduce rework and modelling assumptions
This approach dramatically improves model usefulness and reliability - particularly on refurbishment, adaptive reuse, and complex existing buildings.
A Scoped, Flexible Approach to Modelling
Rather than a one-size-fits-all BIM file, modelling is scoped to suit the project and stage of design.
Typical modelling scopes may include:
External terrain and site context
Typically modelled on a grid basis for design reference
Models are generally delivered to LOD 200–300, depending on the agreed scope.
All modelling is completed in Revit, with export options available for commonly used design platforms including IFC, DWG, Rhino, SketchUp, and others.
Internal base architecture
Walls, floors, ceilings, doors, windows, stairs, and primary joinery outlines
External architecture and façade elements
Building form and external context
Selected internal elements and services (where required)
Lighting, sprinklers, grilles, switches, and other visible fixtures
Accuracy, Tolerance & Appropriate Use
Our BIM models are intended for:
Existing conditions documentation
Concept and design development
Planning, coordination, and design decision-making
They are not intended to replace:
Shop drawing verification
Construction set-out
Final trade sign-off measurements
Being upfront about accuracy and limitations ensures the model is used appropriately — and trusted.
Integrating Survey Data Where Required
For larger, more complex sites or projects requiring higher external accuracy, R24 can coordinate Land Surveyor data alongside the Matterport capture and BIM model.
This hybrid approach allows:
Survey-grade external control where required
Efficient internal capture using LiDAR
A coordinated, consultant-ready model
R24 manages the process, so Architects deal with one point of contact, not multiple disconnected consultants.
Architectural refurbishments and renovations
Typical Project Types
This workflow is well suited to:
Commercial and industrial buildings
Education, healthcare, and institutional assets
Multi-tenancy and adaptive reuse projects
Residential projects requiring reliable existing-condition models
Indicative Pricing
Indicative pricing for small residential projects typically starts in the $1,500–$2,000 range, depending on scope.
Commercial projects are priced based on:
Size and complexity
Modelling inclusions
Required level of detail
Indicative pricing for small residential projects typically starts in the $1,500–$2,000 range, depending on scope.
Start with a Scope Discussion
Every building — and every project — is different.
We begin with:
A quick discussion about intended use
Agreement on scope and level of detail
A clear proposal before modelling begins
