ESi combines structural engineering expertise with advanced modeling tools to assess new and existing structures under real-world conditions. We help clients identify vulnerabilities, validate design performance, and make informed decisions on repair, retrofit, or continued use.
Our structural analysis services deliver detailed evaluations of load-bearing systems to ensure safety, performance, and longevity. We work across a broad range of structures, including bridges, tunnels, storage tanks, pipelines, and residential and commercial buildings. ESi conducts static and dynamic load analysis, stress and strain evaluation, fatigue and vibration analysis, failure mode identification, and forensic investigations of structural issues or collapses.
Projects often include evaluation, design, quality control, program management, and construction engineering. We also develop inspection, maintenance, and construction plans. In support of construction and rehabilitation, ESi provides structural design, site inspections, and expert input during contractor bid reviews.
