ESi provides expert evaluation, damage assessment, and failure investigation for commercial and residential structures of all types. Our multidisciplinary team of structural, civil, architectural, and mechanical engineers works with building owners, property managers, legal professionals, and contractors to assess buildings for safety, code compliance, and performance issues.
In commercial buildings, we evaluate the integrity of key systems including structural frames, fire protection, and building envelopes by inspecting, testing, and monitoring the buildings inside, outside, and underneath for structural damage. We investigate failures caused by fire, water infiltration, mechanical faults, and deterioration, providing detailed analysis to support remediation and risk mitigation.
For residential buildings, which represent the majority of structures nationwide, ESi offers deep experience across thousands of projects. Our engineers understand the common and complex causes of failures in single-family homes, multi-unit dwellings, and high-rise buildings. Services include damage assessments, emergency stabilization, repair scoping, and the preparation of structural and MEP repair drawings. We also advise on code requirements and cost-effective repair solutions.
Whether addressing storm damage, foundation movement, water intrusion, or long-term degradation, ESi provides technical clarity to help clients protect their properties and ensure long-term building performance.
