Heritage Laser Scanning: verified survey data and clear outputs for confident design, planning and delivery decisions.
Heritage laser scanning is a non-contact method of capturing detailed three-dimensional information from historic buildings and other heritage assets. Laser scanners record millions of measurements to create a highly detailed representation of the building as it exists — including complex geometry such as irregular walls, vaulted ceilings, ornate architectural features and stonework.
The difference between heritage laser scanning and a standard building survey is not simply the technology used. Historic buildings require greater consideration of their fabric, access restrictions, conservation requirements and the potential impact of survey activities. Our approach is planned around the sensitivities of the asset, with non-contact capture, carefully selected scanner positions and appropriate documentation — informed by Historic England specialist survey guidance and wider 3D laser scanning workflows. See also our heritage photogrammetry guide .
The resulting information can support conservation, restoration, planning, structural analysis, design development and long-term digital records.
Following site capture, scan data is registered and quality-checked against agreed survey requirements before deliverables are produced — aligned with Historic England recording heritage guidance and RICS measured survey principles .
Heritage assets often remain occupied or accessible to visitors while survey work takes place. We plan capture around opening hours, events, restricted access periods and conservation sensitivities — using non-contact laser scanning to minimise disruption while documenting sensitive environments where physical measurement should be kept to a minimum.
Heritage projects require more than simply bringing a scanner onto site. Our process is designed to minimise physical interaction with historic fabric while providing the information required by conservation and project teams.
We establish survey scope, areas to be captured, required accuracy and intended deliverables. For sensitive heritage sites, the approach can include appropriate risk assessments and method statements covering access, scanner positioning and potential risks to historic fabric.
Laser scanning captures detailed spatial information without physically measuring or attaching equipment to historic fabric. We use terrestrial, mobile or SLAM scanning alongside photogrammetry where appropriate via 3D laser scanning — with scanner positions planned to achieve coverage while minimising disruption to occupants and visitors.
Individual scans are registered and processed into a coordinated point cloud, checked against agreed requirements before final deliverables are produced — including point clouds, CAD, BIM models, textured meshes and digital archives aligned to 3D scanning and listed building survey specifications and heritage survey standards.
Final deliverables in agreed formats (DWG, PDF, RVT, IFC, LAS/LAZ/E57, OBJ/FBX) integrated into conservation, restoration and design workflows.
Heritage laser scanning uses non-contact 3D capture to document the geometry of historic buildings and heritage assets. It provides a detailed digital record for conservation, restoration, planning, structural analysis and archiving — particularly where buildings have complex geometry or sensitive fabric. See our 3D laser scanning service and heritage photogrammetry guide .
We can scope surveys for listed and historic buildings, churches, museums, historic estates, public heritage buildings and other culturally significant assets — each assessed individually across the heritage sector . See our case studies for representative projects.
Depending on project requirements, deliverables can include registered point clouds, 2D CAD drawings, floor plans, elevations, sections, 3D BIM models, textured meshes, orthographic imagery and digital archives — via 3D laser scanning and scan-to-BIM for listed buildings .
Laser scanning is non-contact — the scanner does not need to physically touch surfaces being recorded. We carefully plan scanner positions and access routes to avoid unnecessary contact with historic fabric. For sensitive sites, the methodology can be supported by appropriate risk assessments and method statements, keeping physical intervention and disruption to a minimum.
Yes. Survey information can support Listed Building Consent and Heritage Impact Assessment work by providing accurate existing-condition drawings, elevations, sections and 3D information — via listed building surveys and our listed building consent planning guide .
Duration depends on asset size, complexity, coverage, site access and deliverable detail. Site capture may range from part of a day to several days; processing and CAD/BIM production require additional time. A project-specific programme is provided once scope is understood — contact us to discuss your project.
Common outputs include DWG and PDF for drawings, RVT and IFC for BIM, LAS/LAZ and E57 for point clouds, and OBJ/FBX for suitable textured mesh workflows — agreed before production via 3D laser scanning and scan-to-BIM specifications.
Yes. Survey work can be planned around opening hours, events, visitor access and site restrictions on occupied and publicly accessible heritage assets across the heritage sector . See our case studies for examples on sensitive live sites.
