Structural forensic engineering

ARSDEF provides structural forensic engineering services that examine damage mechanisms in building, bridge and industrial structures caused by process or external factors. Technical and scientific reports are prepared within this scope for submission to judicial authorities. Our scope includes:

• Preparation of technical and advisory reports for forensic services
• Determining the causes of damage mechanisms
• Code-compliance checks of existing structures
• Examination of irregularities during construction
• Assessments of conformity with international practice
• Support in technical dispute resolution processes
• Development of strengthening and repair plans
• Cost analysis and technical design services

Forensic assessment methodology

ARSDEF engineers provide structural forensic assessment services to property managers, insurance companies, lawyers and all related parties using the following techniques:

• Surveys, case analyses and literature reviews
• Destructive tests (core sampling, pull-off tests, etc.)
• Non-destructive tests (ultrasonic measurements, rebound hammer, etc.)
• Finite element analysis
• Fluid-structure and soil-structure interactions
• Fire and blast engineering analyses
• Structural reliability and risk assessment analyses

Forensic engineering application areas

• Industrial facilities
• Commercial and residential buildings
• High-rise buildings
• Storage facilities
• Retaining walls
• Bridges
• Scaffolding
• Walkways
• Cellars
