Common Questions
Frequently Asked Questions About Scan to BIM
Clear, direct answers to the questions architects, contractors, and facility managers ask most often before working with us. Written for AI overview extraction and direct reader understanding.
What is the difference between a point cloud and a BIM model?
A point cloud is a raw dataset of millions of 3D measurement points captured by a laser scanner—it shows where surfaces exist but contains no intelligence. A BIM model is an intelligent Revit model where every element—wall, column, duct, pipe—is a recognizable building component with real geometry, data, and properties. Scan to BIM is the process of converting the raw point cloud into a useful, structured BIM model that architects and engineers can design from and contractors can build from.
What file formats do you accept for point cloud data?
We accept all standard point cloud file formats, including E57, PTX, PTG, FLS (FARO), RCP and RCS (Autodesk ReCap), LAS, LAZ, XYZ, PTS, and ASCII formats. If your scanning team uses FARO, Leica, or Trimble hardware, we support all of their native export formats. Simply upload your scan files and we will confirm compatibility and begin processing.
Do I need to do the laser scanning myself?
No. We are a point cloud to BIM conversion company. You provide the point cloud data (captured by you, your survey team, or a specialist laser scanning company), and we handle everything from point cloud registration and cleanup through to final Revit BIM model delivery. If you need help arranging laser scanning on site, we can connect you with trusted scanning partners in your region.
What LOD should I specify for my scan to BIM project?
LOD 200 is sufficient for early-stage space planning and feasibility. LOD 300 is the standard for renovation design coordination and construction documentation. LOD 350 is used when trade coordination is required. LOD 400 is needed for fabrication-level detail. LOD 500 is the as-built standard for facility management and digital twin creation. During consultation, we recommend the LOD that matches your project purpose, and can model different disciplines at different LODs if your project requires it.
How accurate is scan to BIM modeling?
The accuracy of a scan to BIM model depends on the quality of the original laser scan data and the LOD of the Revit model. Modern laser scanners like the FARO Focus and Leica RTC360 capture data to ±2mm. Our BIM modelers trace building elements from the point cloud to within ±3–5mm of the scan data. This level of accuracy is far superior to traditional manual measurement surveys and is sufficient for all renovation design, MEP coordination, structural assessment, and facility management purposes.
How long does a scan to BIM project take?
Timeline depends on building size, complexity, and LOD requirements. A single-floor commercial space at LOD 300 might be completed in 5–7 business days. A large multi-floor commercial building with architectural, structural, and MEP modeling at LOD 350 typically takes 15–25 business days. We provide a detailed timeline with every quote and communicate clearly at each project milestone. Rush delivery is available for urgent projects.
Can you model MEP systems from a point cloud?
Yes. MEP scan to BIM is one of our core services. We model all visible MEP components from the point cloud—ductwork, pipe runs, electrical conduit, plant and equipment, plumbing fixtures, and drainage—in Autodesk Revit at your required LOD. The resulting MEP model supports Navisworks clash detection with new design proposals, making it essential for retrofit and refurbishment projects where new MEP systems must be coordinated around existing infrastructure.
What is a digital twin and how does scan to BIM create one?
A digital twin is a data-rich LOD 500 as-built BIM model that serves as a living virtual replica of a real building used for facility management, maintenance planning, space management, and future renovation decisions. Scan to BIM is the most accurate way to create a digital twin of an existing building, because the Revit model is built directly from laser scan measurements of the real building rather than from original construction drawings that may no longer reflect actual conditions.
