Heritage Documentation Scanning
Heritage documentation scanning uses 3D laser technology to create precise permanent records of historic buildings, monuments, and cultural landscapes. Brisbane Point Cloud provides archive-grade heritage surveys compliant with the Burra Charter and state heritage requirements across Australia.

Our Process
How we work
Heritage Assessment
We review the significance and condition of the structure, identify access constraints, and coordinate with heritage consultants or managing authorities. A scan plan is developed to capture all required views without physical contact.
Non-Contact Capture
Scanning proceeds with zero physical contact to the heritage fabric. Our scanners are tripod-mounted, eye-safe, and produce no vibration, light damage, or surface contact. We document every scan position for future reference.
Measured Documentation
From the point cloud, we produce measured drawings (plans, sections, elevations) to the level of detail required by the heritage advisor or managing authority. Decorative elements, mouldings, and irregular geometry are captured faithfully.
Archival Package
Deliverables are packaged for long-term archival: open file formats, comprehensive metadata, coordinate system documentation, and a record of capture methodology. Files are suitable for lodgement with state heritage registers.
FAQs
Common questions
Is laser scanning safe for heritage buildings?
Yes. Laser scanning is entirely non-contact and non-invasive. The Class 1 laser used by our equipment is eye-safe and operates at power levels far below those that could affect paint, timber, stone, or any building material. There is no UV component, no heat transfer, and no physical contact with the building fabric. The scanner sits on a tripod at a minimum distance of 1-2m from surfaces. Scanning is approved for use in museums, churches, galleries, and state/national heritage listed buildings without restriction. Many Australian state heritage offices now recommend or require 3D scanning as part of heritage management plans.
What heritage standards do you follow?
We align our documentation methodology with the Burra Charter (Australia ICOMOS Charter for Places of Cultural Significance, 2013 revision), which establishes the principles for conservation of cultural heritage places in Australia. Our measured surveys comply with the ICOMOS Principles for the Recording of Monuments, Groups of Buildings and Sites (1996). For Queensland heritage-listed places, we follow the Queensland Heritage Act 1992 requirements for heritage impact assessments. Our deliverables are formatted for submission to state heritage registers and are accepted by heritage consultants for conservation management plans.
Can you produce Heritage BIM (HBIM) models?
Yes. Heritage BIM adapts standard BIM methodology for historic buildings where elements are non-standard, irregular, and often unique. We model heritage elements using custom Revit families that accurately represent as-found conditions: irregular wall profiles, out-of-plumb columns, sagging floors, hand-crafted mouldings, and non-repetitive decorative elements. HBIM models support ongoing facilities management, conservation planning, and design coordination for adaptive reuse projects. Each element carries metadata about construction material, condition, and heritage significance where this information is provided by the heritage consultant.
How detailed are heritage measured drawings?
Detail level depends on the purpose. For conservation management plans, we typically produce drawings at 1:50 scale showing overall geometry, openings, key architectural features, and structural elements. For detailed restoration work, we produce 1:20 or 1:10 drawings of specific elements (cornices, columns, window assemblies, decorative panels) with all profile information visible. The point cloud captures everything at scanner resolution (sub-millimetre point spacing at close range), so we can extract drawings at any scale or detail level from the same dataset without returning to site.
Can scanning detect structural movement or damage?
Yes. Point cloud analysis can identify deviations from expected geometry: out-of-plumb walls, sagging beams, floor level variations, and crack patterns. We produce deviation colour maps that visually highlight areas departing from a reference plane or design geometry. For monitoring over time, repeat scans at set intervals allow us to measure millimetre-level structural movements (settlement, tilt, deflection). This is particularly valuable for heritage structures where direct measurement methods (drilling for crack monitors, attaching sensors) are not permitted on the fabric.
What format should heritage scan data be archived in?
We recommend E57 as the primary archival format for heritage point cloud data. E57 is an open, vendor-neutral standard maintained by ASTM International (ASTM E2807). It stores point coordinates, intensity, colour, and scanner metadata in a structured binary format with optional compression. Unlike proprietary formats that may become unreadable as software versions change, E57 has broad industry support and a published specification. We also supply a secondary copy in LAS format for GIS applications. Both formats are suitable for submission to state heritage archives and will remain readable for decades.
