Learn how InferTrust™ AEC creates cryptographic proof for every AI-assisted bridge load rating, fatigue analysis, and structural evaluation to defend against po
Bridge engineering firms deploying AI for load rating, fatigue life prediction, scour vulnerability assessment, and seismic analysis face unique liability exposure. A single bridge carries tens of thousands of vehicles daily, and a failure can generate hundreds of millions of dollars in litigation. InferTrust™ AEC (Patent Pending) creates sealed decision records for every AI-assisted bridge evaluation, providing the evidentiary foundation that survives forensic investigation and adversarial discovery.
For each bridge evaluation, InferTrust™ AEC seals the specific AASHTO LRFD edition and load factors used, the bridge element evaluated (deck, superstructure, substructure, bearings, joints), the load combinations and live load models applied, the calculated rating factors or demand-to-capacity ratios, the deterioration model version and condition state inputs, and the resulting decision action (AEC_APPROVE, AEC_FLAG, AEC_RESTRICT, or AEC_ESCALATE). Each record is cryptographically signed with timestamps and sequence counters, creating a tamper-evident chain that documents the entire evaluation history for every bridge element.
National Bridge Inspection Standards require systematic documentation of bridge condition assessments. InferTrust™ AEC supports NBIS compliance by sealing element-level condition ratings, NBI coding determinations, and inspection interval calculations into the decision chain. When FHWA or state DOT auditors review inspection records, the cryptographic guarantees provide verification that records were created at the time of inspection and have not been modified since.
When a bridge failure triggers investigation and litigation, InferTrust™ decision records provide definitive answers to the questions forensic engineers and attorneys will ask: which model version evaluated the bridge, what parameters it used, whether it flagged any concerns, and whether those concerns were addressed by the licensed PE. This transforms litigation defense from a document reconstruction exercise into a straightforward evidence review.
