When disaster strikes, ESi quickly mobilizes a multidisciplinary team to deliver the technical clarity needed during critical moments. Whether a plane crash, train derailment, crane collapse, or major structural failure, our experts combine technical depth in civil, structural, aerospace, mechanical, and electrical engineering to address incidents involving significant property loss or loss of life.
With experience across transportation, construction, energy, and manufacturing sectors, we rapidly assess complex events. Our investigators leverage advanced tools such as 3D laser scanning, drone photogrammetry, and FARO technologies to accurately document scenes, preserve critical evidence, and support root cause analysis.
Our end-to-end services include on-site inspection, evidence collection, hazardous materials evaluation, stabilization oversight, and coordination with insurers, regulators, and legal teams. We are also equipped to manage technical challenges in chaotic or hazardous environments, ensuring safe and efficient site access and data recovery.
ESi’s technical depth is matched by our ability to communicate findings clearly. From initial response through litigation support, we provide clients with concise, actionable insights. Whether guiding recovery operations or preparing expert testimony, ESi delivers reliable, defensible conclusions—helping clients make informed decisions during the most critical moments.
