What we do
Scan to BIM converts reality capture data (point clouds) into structured BIM models your team can use with confidence for design development, coordination and verification.
Rockall Projects produces Revit and/or IFC models to an agreed level of detail and model scope, aligned to what you actually need the model to do—whether that’s de-risking a refurbishment, coordinating MEP in constrained areas, or establishing reliable existing-condition geometry when record drawings can’t be trusted.
Already have scans? We can work from client-supplied point clouds where suitable, or provide capture as part of the package.
Typical uses for Scan to BIM
Scan to BIM is most valuable when programme, access, and certainty matter:
- Refurbishment and fit-out where existing information is incomplete or unreliable
- Design coordination / clash avoidance (architecture, structure, MEP)
- Verification of installed works vs design intent
- Complex zones: plant rooms, risers, ceiling voids, congested service corridors
- Change control where accurate base data reduces RFIs and rework
- Handover readiness where model structure supports ongoing use (where required)
Deliverables
We agree deliverables upfront so the outputs match the downstream workflow.
Common deliverables include:
- Revit model (RVT) and/or IFC export
- Point cloud deliverables (e.g., RCP/RCS, E57 or as required)
- 2D drawings extracted from the model (plans/sections/elevations) where required
- Model structured by levels / zones / areas for coordination
- Agreed naming conventions, worksets, and model breakdown (where required)
- Handover notes including scope boundaries, assumptions, and any access constraints
If you have BIM standards (naming, shared coordinates, classification), we can align to them where practical.
Level of detail and scope
The biggest risk in Scan to BIM is not “accuracy” — it’s misaligned expectations about what’s being modelled and why.
We define scope in clear terms, for example:
- what is included/excluded (structure, architectural elements, MEP, primary routes only, etc.)
- any tolerance / fit-for-purpose expectations
- expected model uses (coordination, spatial planning, verification, drawing extraction)
- what areas are “no access / no visibility” and therefore cannot be confirmed
If you’re unsure what you need, we’ll recommend a pragmatic approach that supports decisions without unnecessary over-modelling.
Our process
- Brief and scope definition
Use case, areas, access constraints, programme, deliverables, and modelling rules. - Capture / point cloud readiness
We either undertake site capture or assess client-supplied data for completeness and suitability. - Registration and data preparation
Point cloud structured, cleaned where appropriate, and set up for modelling. - Modelling (Revit/IFC)
Model created to the agreed scope and level of detail, with sensible segmentation for coordination. - QA and validation
Systematic checks against the point cloud and documented resolution of queries/assumptions. - Delivery and handover
File set delivered in agreed formats, plus a short handover pack explaining scope, assumptions and model structure.
FAQs
What do you need from us to quote?
Ideally:
- site address and any access constraints
- areas to be scanned/modelled (and any exclusions)
- intended model use (coordination / refurb planning / verification / drawings)
- required outputs (RVT / IFC / 2D drawings / point cloud formats)
- programme dates and any site restrictions
- any BIM standards you need us to follow
Can you work from an existing point cloud?
Often yes—provided it’s complete for the required areas and suitable quality. We’ll review what you have and confirm suitability before committing.
What affects timescales?
Key drivers are size/complexity, access, required scope (what’s being modelled), and the level of detail. Targeted modelling of high-risk zones can often deliver value faster than modelling everything.
What file formats do you deliver?
Commonly RVT and IFC plus point cloud formats such as RCP/RCS or E57 (as agreed). If you have a preferred workflow, tell us at enquiry stage and we’ll align the outputs.
Do you model MEP?
We can, but MEP scope should be defined carefully (e.g., primary routes only vs detailed plant/containment). The right approach depends on how you intend to coordinate.
