Measured existing-condition information for conservation architects planning sensitive alteration, repair or listed building consent. Agree the survey extent and the required drawings, point clouds or visual records at briefing.
A listed building survey records the visible, accessible geometry needed for a defined conservation or design task. A brief may cover a whole building or selected rooms, façades, roofs and architectural details. The drawings are a measured basis for the architect and heritage consultant; the survey itself does not determine significance, diagnose condition or secure consent.
Floor plans, elevations and sections can be prepared from a measured building survey. Terrestrial heritage laser scanning can establish a registered spatial record where complex geometry or broader coverage warrants it. Photogrammetry and orthographic imagery can add visual surface detail when specified; a BIM model is a separate, scoped output.
At briefing we agree what is visible and accessible, the required detail and tolerances, survey control, drawing conventions, formats and exclusions. Concealed fabric, inaccessible areas and material condition require separate investigation by the appropriate specialists.
We agree control, coordinate reference, survey tolerances and the required drawing or model detail before capture. The registered data and outputs are checked against that brief; unobserved or inaccessible areas are identified rather than inferred as measured facts.
Site access, occupiers, fragile surfaces and any restrictions on equipment positions are discussed with the project team. Non-contact scanning reduces direct contact with visible fabric, but safe access and permission still govern what can be recorded.
Coverage, detail, reference and intended outputs are recorded before capture.
Control and registration are checked against the method specified for the project.
Selected drawings are checked against source survey data and the agreed brief.
Inaccessible or unobserved areas are noted for the project team.
We plan capture around the project brief, the building and access conditions. The agreed survey extent determines methods and outputs.
We agree the affected areas, drawing scales, level of detail, reference system, tolerances and access. The methods and exclusions are set before site work — contact us to discuss your project.
Laser scanning records visible geometry without surface contact. Scanner positions are planned for the agreed extent, while access and line-of-sight gaps are recorded — via 3D laser scanning for the specialist recording method.
Captured data is registered and checked against the brief before the selected plans, elevations, sections or point cloud are produced. A BIM model is separately scoped via scan-to-BIM with agreed elements and detail.
Deliver the commissioned formats with the survey extent and known gaps stated, so the architect and heritage consultant can use the record in their own design and consent work.
Identify the listed building and project stage, mark the rooms, façades, roofs or details affected, and state the intended drawings, scale or level of detail, formats, reference system and programme. Share access restrictions and existing information so exclusions can be priced clearly.
Measured existing-condition drawings can support an architect and heritage consultant preparing a consent submission. The appointed team decides what information the authority requires and is responsible for the application and significance assessment.
Terrestrial laser scanning measures visible surfaces without touching them. Coverage still depends on line of sight and agreed access. Occupancy, fragile areas and restrictions are planned before site work.
Only the outputs agreed in the brief are included. A registered point cloud, orthographic imagery, photo record and BIM/HBIM model serve different purposes; we can specify them separately and identify formats and limitations in the quotation.
No. A measured survey records defined visible geometry and selected visual information. Condition inspection, fabric opening, historical interpretation and heritage statements require separate specialist scopes.
