Forensic Engineering and Failure Analysis
Investigation of structural collapses, failures and accidents to determine cause, for owners, insurers and attorneys.
What the work involves
Forensic engineers investigate why a structure, wall, slope, pavement, pipe or other component failed. They document the scene, collect and test samples, review design and construction records, run calculations and identify the cause and contributing factors. Findings support insurance claims, litigation, repair design and preventing repeat failures.
Local conditions we plan for
- Deep frost penetration
- Heavy snow loads
- Great Lakes shoreline erosion
- Karst in the southwest Driftless Area and Door County
Building code: IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026).
When you need it
- Collapse of a structure, wall, roof or deck
- Unexplained cracking or deformation
- Pipe, culvert or pavement failure
- Accident involving a structure
Frequently asked questions
How much does forensic Engineering and Failure Analysis cost?
Across the US, forensic Engineering and Failure Analysis usually costs $2,500 to $50,000 per investigation. Estimate. Ranges widely with complexity and testing; billed hourly at expert rates (see SEAK survey).
How long does forensic Engineering and Failure Analysis take?
Plan on Weeks to months from signed proposal to stamped deliverables, longer if a site visit, soil testing or a permit review cycle is involved.
Is a permit required for forensic Engineering and Failure Analysis?
Often not on its own, but the findings frequently lead to work that does need a permit. We tell you which parts of the follow-up work your local building department will review, and can prepare those drawings too.
How do I verify an engineer's license in Wisconsin?
Engineers practicing in Wisconsin are licensed by the Wisconsin Examining Board of Architects, Landscape Architects, Professional Engineers, Designers and Professional Land Surveyors. You can confirm a license number and its status in the board's public license search before you sign a contract.
How deep is the frost line in Wisconsin?
Wisconsin Uniform Dwelling Code SPS 321.16 requires footings to be below frost penetration or at least 48 inches below adjacent grade, whichever is deeper (one and two family dwellings). Local building departments set the required footing depth, so confirm the exact figure for your county before designing foundations or retaining walls.
Which building code applies in Wisconsin?
IBC 2021 statewide for commercial buildings; one and two family dwellings use the state Uniform Dwelling Code instead of the IRC (ICC adoption chart, April 2026). Cities and counties can add local amendments, which is one reason to hire an engineer who works in your area.
