Heritage Survey
An as-built survey of a historic structure — irregular masonry and non-standard geometry, captured at the same accuracy standard as a modern building, because heritage structures rarely have accurate original drawings to fall back on.
Usually delivered as a Level 3 Aligned/Superimposed Scan to CAD drawing, often with the point cloud overlaid against a colored BIM floor plan so renovation architects can compare the two directly.
Frequently asked
Why does a heritage survey need extra care compared to a modern building?
Irregular masonry surfaces and non-orthogonal walls get smoothed over by a purely drawn approach — we draft directly from the point cloud so the real, imperfect geometry is preserved.
Can you overlay the survey against a renovation design?
Yes — we regularly overlay the point cloud with a colored BIM floor plan so architects can directly compare planned changes against the real building.
Is this suitable for a listed/protected building?
Yes — the survey itself is non-invasive (laser scanning, no physical contact with the structure), which is usually a requirement for protected buildings.
Will the irregular, non-standard geometry be smoothed out in the drawing?
No — that's the whole point of drafting from the point cloud rather than eyeballing measurements; genuine wall bowing, out-of-square corners, and settlement are preserved, not corrected away.
How long does a heritage survey take?
Typically longer than a standard rölöve survey at the same square footage, because Level 3 Aligned/Superimposed output is the default here — see the Scan to CAD turnaround table for Level 3 timing, then add time for any restricted-access areas.
