3D Laser Scanning for Heritage Buildings: A WebPano Case Study
On a live construction site involving a protected, heritage building, resolving a design conflict or planning a crane lift usually means more site visits, more drawings, and more back-and-forth between teams. This case study shows how 3D laser scanning for heritage buildings — captured with WebPano — let a project team handle both design coordination and construction planning from their desks, using a 360° scan and point cloud instead of a full BIM model.
3D Laser Scanning for Heritage Buildings: Solving a Design Conflict
When a new mechanical line needed to tie into an existing system inside a listed building, the project manager didn’t need to walk the site to find the right spot. Moving through the point cloud, they located the exact connection point, added a 2D markup, and sent a link straight to the MEP consultant. No drawings to interpret, no email attachments, no site visit needed to confirm it. When the proposed route was later challenged, the same markup was checked directly against the scan, adjusted, and re-approved — with sign-off from the facilities team and the conservation officer, all without leaving the platform.

The same approach carried through to the construction phase. A 3D crane model was uploaded directly into the scanned scene to plan its placement, and a cylindrical markup checked its reach against the surrounding structure. A duplicated barrier markup traced the full exclusion zone around it. Throughout, the team moved freely between the model and the raw point cloud — markups work on either, and the point cloud alone often reveals detail a model never captured in the first place.
For architecture and design offices, and for anyone managing a large, complex, or historically sensitive building, this is what 3D laser scanning for heritage buildings makes possible: real design and construction decisions, made with confidence, even without a full BIM model.
