Scan to BIM Services

Scan to BIM is the process of capturing an existing building or structure using 3D laser scanning, registering the measured point cloud and using that data as the reference for an as-built building information model. The required model content and detail are agreed for the intended project use.

Scan to BIM is the wider term for producing a building information model from measured scan data. Scan to Revit usually describes the same survey-to-model workflow where Autodesk Revit is the required modelling software and native file format.

A point cloud is the measured three-dimensional dataset created from the laser scan. A BIM model is a structured and interpreted model in which the required walls, floors, roofs, openings and other agreed elements are created using the point cloud as the measured reference.

The cost of Scan to BIM depends on the building size, survey extent, access conditions, model disciplines, required level of detail, Revit version, IFC requirements, modelling complexity, checking requirements and project timescale. Existing plans, photographs, a marked-up survey extent and a clear modelling specification help us prepare an accurate quotation.

The programme depends on the building size, complexity, access, survey extent, required model content, level of detail and checking requirements. Smaller Scan to BIM projects may be completed more quickly, while larger buildings, complex geometry or detailed modelling requirements can need additional survey and production time.

The achievable model accuracy depends on the survey specification, site conditions, visibility, scan registration, survey control, model scope and the way the surveyed geometry is interpreted. The required accuracy and level of detail should be agreed for the intended use rather than assumed from a general figure.

The required level of detail (LOD) can range from a basic structural representation to a more detailed architectural, structural or MEP model. Because LOD terminology varies across the industry, the quotation defines the exact building elements, geometric detail, model information, inclusions and exclusions required for the intended use. Complex or information-rich elements may require additional production time and should be specified before quotation.

Yes. Survey-grade laser scanning is particularly useful for recording complex and irregular existing geometry. The model scope should identify which architectural features need to be represented and at what level of detail, as highly ornate elements may require separate modelling allowances.

The registered point cloud, native Revit model and IFC files can be provided where required. Uniclass classification can also be included within the agreed model scope. We supply fully parametric BIM-ready existing-building models but do not provide a full BIM information-management service.

Yes. Architectural, structural and MEP models can be produced where the required elements are visible and defined in the agreed scope. Structural steelwork is represented using best-fit section sizes rather than verified manufacturer-standard sections. MEP modelling can include visible pipes, ducts, cable trays, service routes and major plant, but it does not generally identify the services. Hidden elements are included only where reliable supporting information is supplied and their treatment is specifically agreed.

Yes. Topographical site models can be produced from coordinated survey data where required, representing agreed terrain, buildings, site features and visible infrastructure within the project area. The exact site extent, model content, level of detail and required outputs are defined in the quotation.

Yes. Pinpoint Mapping provides Scan to BIM services across Bristol, Bath and the wider South West, including Gloucestershire, Somerset, Wiltshire and South Wales. Projects farther afield can also be considered depending on the survey scope and programme.

Please send the site address, approximate building or site size, required survey extent, intended model use, required model type, disciplines and elements, level of detail (LOD), model information, Revit version, IFC or other outputs, access information and timescale. Existing plans, photographs, marked-up drawings and any client modelling specification are particularly helpful.
