Forensic 3D Scanning for Claims, Defects and Structural Failures

What forensic 3D scanning documents: cracks, spalls, settlement, deflection, failed members

A forensic scan captures the condition of a structure or component at a known date and time, in full color, at a resolution fine enough to measure a hairline crack. Slab and wall cracking, spalled or delaminated concrete, settled footings, deflected beams, out-of-plumb columns, fractured welds and bolts, fire-damaged steel, and storm-torn roof assemblies are all within range of a handheld scanner, and all of them disappear the moment repair starts.

Because the scanner records geometry rather than a picture of it, the model can be measured in ways nobody thought to ask about on the day: the width of a crack at a point three feet from the column, the gap under a straightedge, the angle of a leaning wall. That is the difference between evidence and photographs.

3D scanning for insurance claims — storm, fire and collapse losses

Adjusters and claims managers use scan data to settle scope: what was damaged, how much, and whether the damage pre-dated the event. For hurricane, hail, and wind losses along the Gulf Coast we scan damaged assemblies before the restoration contractor starts, and we scan undamaged baseline conditions for owners who want a pre-storm record. For fire losses the scan preserves char depth, deformed steel, and spall patterns for origin-and-cause work. For collapses the scan is taken before the debris is moved, so the position of every member is preserved.

Construction defect documentation for litigation and expert witness support

Construction defect matters turn on what was built versus what was specified. We scan the as-built condition — cover, dimensions, flatness, alignment, finish — and overlay it on the contract drawings so counsel and the engineer can see the deviation measured rather than argued. The scan technician documents the capture procedure, equipment, settings, and controls so the person who oversaw the capture can describe it under oath; opinions about cause and responsibility are given by licensed engineers engaged for the matter, not by us.

Crack mapping and deformation measurement from the point cloud

From the model we produce a crack map — every crack located, its length traced, widths measured at stated intervals — and deformation measurements: beam and slab deflection against a best-fit plane, floor levelness, column and wall plumb, and bulge or bow in masonry. Repeat scans at intervals show whether a crack is growing or a wall is still moving, which is the question an owner asks before deciding between monitoring and shoring.

Structural failure documentation before demolition or repair

When a member fails, there is a short window between making the site safe and clearing it. A handheld scanner needs no tripod, no targets, and no power on site, so we can capture a failed connection, a punched slab, or a buckled column in the minutes the safety plan allows, from the angles a tripod scanner cannot reach. Fracture surfaces, deformed shapes, and the positions of fallen pieces are preserved in one model before anyone touches them.

Deliverables: point cloud, measurements, exhibits, chain of custody

Each matter receives a time-stamped registered scan, a color mesh, a measurement report with the figures the engineer asked for, annotated crack maps and section cuts suitable for exhibits, and a chain-of-custody log covering capture, processing, and storage. Where samples are needed we core and sample under the same custody record through our forensic engineering group, so the physical and digital evidence share one file.

Forensic 3D scanning in Houston and nationwide — working with your forensic engineer

Houston, Harris County, and Fort Bend County matters are scanned from Sugar Land as soon as the site is safe to enter. Elsewhere we mobilize from the nearest regional hub. We work as the scanning subcontractor to forensic engineering firms, insurers, and law firms that do not keep a handheld scanner on staff, delivering data in the formats their engineers use, under their protocols, without duplicating their role.
