Structural Forensic Engineering

NV5’s structural forensic engineers are consulted to determine the cause of an unexpected performance of a structure. They routinely determine the primary cause of an incident and any contributing physical factors. This determination must be made prior to establishing the responsibility and liability of the structural damage or failure.

We provide consultation, investigation, and scientific analysis; prepare technical reports; and serve as expert witnesses for a variety of project sites including residential and commercial buildings, high-rise structures, industrial facilities, historic structures, seawalls, and piers. Our areas of specific expertise include roofing, foundations, building envelopes, water intrusion, evaluation of construction defects, and premises liability evaluations.
