Scan to BIM Services

Scan to BIM is the process of using a registered point cloud as the reference for building a structured existing-conditions model in Revit or another BIM authoring tool. The point cloud is captured using 3D laser scanning. A technician uses that scan data as a dimensional reference to model the agreed elements at the agreed level of detail. The scanner does not automatically generate the model. Modeling requires scope definition, production decisions, and QA review against the point cloud before delivery.

Scan to BIM produces a structured 3D model in a format like RVT or IFC. As-built drawings produce 2D views in DWG or PDF. The right deliverable depends on the downstream team's software and what they need to do with the data. A team working in Revit that needs an existing-conditions model as a reference for design coordination typically needs Scan to BIM. A team using AutoCAD that needs a flat drawing to design from or share with contractors typically needs as-built drawings. See our as-built drawing services for more detail.

Level of detail describes how precisely each element in the model is built and what it includes. A wall modeled at a basic level might be a solid volume at the correct location and height. A wall modeled at a more detailed level might include layer breakdown, precisely dimensioned openings, and carefully resolved edge conditions. The level of detail for each element type should be agreed before production begins. Confirming what the project actually needs prevents both under-delivery and unnecessary production cost.

RVT is the primary delivery format for most Scan to BIM projects. IFC can support open-format interoperability when a modeled deliverable is in scope. DWG and PDF drawing sheets can be included when drawing output is part of the agreed scope. The registered point cloud reference can also be delivered alongside the model when in scope. Revit version compatibility should be confirmed during scoping to avoid file-opening problems at handoff.

Revit is the primary BIM authoring tool for most Scan to BIM workflows. The registered point cloud serves as the dimensional reference during modeling. IFC export is available for teams whose downstream platform requires open-format model delivery. The scanner itself does not produce the model: the model is built by a technician using the scan data as a reference.

Model accuracy depends on the quality of the point cloud, the scanner and field workflow used during capture, site conditions and surface types, field coverage, and the agreed level of detail. Accuracy requirements should be discussed during scope confirmation. We do not state a specific tolerance because the right answer varies by project.

The most common sources of rework are: scope not defined before production began, areas that could not be accessed during the field visit, reflective or moving surfaces that produced limited point cloud data, level of detail not confirmed before modeling started, a Revit version mismatch between production and the project team, and file format requirements discussed after delivery. Most of these are manageable when identified during scoping.

Cost depends on the size of the area, point cloud quality, modeling scope, element density, required level of detail, file formats, Revit version requirements, and whether the project needs architectural, structural, MEP, or combined modeling. The scope should be confirmed before quoting.
