Scan to BIM converts verified point cloud survey data into scoped Revit or IFC models for design coordination, refurbishment, retrofit and existing-building asset workflows.
Scan to BIM is the process of converting 3D laser scanning data into a structured Building Information Model. Laser scanners capture millions of measurements from an existing building, creating a registered point cloud that represents the building as it exists. It is then used as the reference for creating a BIM model in software such as Revit.
Instead of relying on incomplete drawings or assumptions, the model is developed from measured survey data via 3D laser scanning and can include agreed architectural, structural or MEP elements with the model content, LOD and LOI defined around the intended use. See our scan-to-BIM for listed buildings guide for heritage workflows aligned to ISO 19650 principles.
The resulting BIM model can support design development, refurbishment, retrofit, coordination, clash detection and asset management when its content and level of information are agreed for that purpose.
The point cloud is used as the primary geometric reference during modelling. Our QA process includes visual comparison against the point cloud, deviation checks, sample measurements, model geometry checks, element and category checks, and review against agreed LOD requirements and project tolerances.
The completed model is delivered in the agreed formats and structure, ready for the next stage of the project workflow, ensuring the model represents the surveyed building rather than relying on assumptions or nominal dimensions.
Our process gives project teams a clear route from existing survey information to a usable, coordination-ready BIM model.
We establish areas to be modelled, required disciplines, LOD, Revit/IFC requirements, naming conventions, client BIM standards and deliverables before modelling begins. Contact us with your BEP or modelling requirements.
Geo Scan undertakes the site survey for the agreed model, including 3D laser scanning and point cloud registration, aligned to as-built survey control where required.
The BIM model is developed against the registered point cloud with visual comparison, deviation checks, sample measurements and LOD verification, aligned to project-specific scan-to-BIM standards before issue.
Completed models delivered in agreed formats (RVT, IFC, NWC/NWD, DWG, PDF) ready for design coordination, clash detection and construction workflows.
Scan to BIM converts 3D laser scan point cloud data into a structured BIM model, a measured digital representation for design, refurbishment, coordination, clash detection and asset management where existing drawings are incomplete or unreliable. See our scan-to-BIM guide and 3D laser scanning service.
Send the site address, survey extent, access constraints and required disciplines, intended model use, LOD and information requirements, Revit version, coordinate system, naming or classification standards, required RVT or IFC deliverables and target programme. Include any EIR, BEP, model matrix, template or sample model so the quotation reflects the real production and QA scope.
We agree the model purpose, disciplines, geometry, information content, tolerances, exclusions and required outputs before production. LOD terminology is recorded in the project specification rather than treated as a universal promise about every element. See scan-to-BIM for listed buildings for heritage-appropriate LOD scoping.
Common formats include RVT (Revit), IFC, NWC/NWD for coordination workflows, plus 2D CAD and PDF extracts where required, agreed before production via 3D laser scanning and as-built survey specifications.
Timescales depend on area modelled, building complexity, disciplines, LOD and QA requirements. We provide a project-specific programme based on agreed scope. contact us with your project details.
Geo Scan produces BIM models from its own captured and registered survey data. We do not convert third-party point clouds. The workflow starts with 3D laser scanning and point cloud capture through to BIM modelling and delivery, aligned to as-built survey control.
The point cloud is the primary geometric reference during modelling. QA includes visual comparison, deviation checks, sample measurements and review against agreed tolerances and LOD requirements via 3D laser scanning and scan-to-BIM QA workflows .
Yes. We produce coordination-ready models suitable for Navisworks and multidisciplinary clash detection, supporting 3D laser scanning and refurbishment as-built coordination workflows.
