Sea Wall & Quay Sheet Pile 3D Mapping
Photogrammetric 3D scans of harbor retaining walls and sheet pilings, letting engineers track bowing, rust holes, and concrete erosion over time.
What This Involves
A harbor retaining wall or sheet-pile quay degrades slowly and mostly out of sight below the waterline — which is exactly why it tends to get inspected reactively, after a visible problem shows up onshore. We produce a full photogrammetric 3D model of the submerged structure, giving engineers a real baseline to track bowing, corrosion holes, and concrete erosion against on each subsequent survey, rather than relying on diver notes that are hard to compare year to year.
How It's Done
Full-length photogrammetric pass of the submerged wall or piling face
3D reconstruction referenced to a fixed survey datum so repeat surveys are directly comparable
Direct measurement of deflection, section loss, and erosion within the model
Change detection against a prior survey where one exists
Deliverable
A georeferenced 3D model of the structure, with measurable deflection and erosion data comparable across surveys.
Who It's For
Port authorities and civil engineers responsible for retaining wall and quay condition monitoring.
