Diana Estrada

Ms. Estrada is a Senior Managing Consultant and Director at Engineering Systems Inc. (ESi), providing expert consultation in structural, construction materials, and civil engineering forensics. She is routinely retained to lead investigations ranging from performance and serviceability issues to complex, multidisciplinary failures of buildings and infrastructure systems. Her work focuses on determining origin, cause, failure mechanisms, and extent of damage, providing a technical basis for the evaluation of design deficiencies, material performance, construction defects, code compliance, maintenance issues, and extreme events.

Ms. Estrada investigates a broad range of matters, from residential claims and construction defects to large-scale structural failures and catastrophic collapses. Her work also includes structural integrity assessments, code compliance, and failures occurring during both construction and in-service conditions. She also develops repair scopes and designs, supporting the evaluation and design of repairs for partially or fully damaged structures following an event.

Her expertise includes cementitious materials and structural systems, including reinforced and prestressed concrete, steel, and wood, with particular strength in evaluating how material behavior influences system-level performance and failure.

Ms. Estrada has conducted slip resistance testing and has performed code investigations for personal injury and premises liability matters involving slip/trip/fall incidents, local and building code requirements, and issues related to ADA compliance. Her background includes research on damage mechanisms, residual capacity, and repair of concrete structures, integrating field investigations and laboratory testing to evaluate performance, failures, and repair effectiveness.

Prior to joining ESi, Ms. Estrada worked across the full project lifecycle, including design, preconstruction, construction, and commissioning for Design-Build and Design-Bid-Build projects, both domestic and international. Her experience spans commercial facilities, railroad infrastructure, civil sitework, oil and gas, and drinking and wastewater treatment facilities. She led preconstruction and estimating efforts, evaluating risk, cost, constructability, and schedule impacts.

Ms. Estrada has also provided oversight and direct management of construction projects, including day-to-day operations, identification and analysis of constructability constraints, and coordination of multidisciplinary teams.
