Forensic Engineering & Consulting Services
ENA2 investigates structural damage, cracking, excessive deformation and unexpected failure in buildings, industrial structures and equipment supports. Our forensic engineering services combine engineering document review, structural failure analysis and targeted Finite Element Analysis (FEA) to examine possible failure mechanisms and define appropriate next steps.
What Is Forensic Structural Investigation?
Forensic structural investigation examines why a structure or component has failed, deteriorated or performed differently from its intended design. Engineers consider observed damage, drawings, material condition, construction details, load paths, maintenance records and loading history. Forensic failure analysis compares possible causes with the evidence; calculations and simulation are used where they can answer a defined engineering question.
ENA2's forensic engineering and consulting services support structural damage assessments, repair planning and engineering reviews for insurance claims or disputes. Investigation scope depends on the affected asset, the available evidence and the technical questions to be answered.
Comprehensive Forensic Engineering Services
Structural Failure Root Cause Analysis
Structural failure analysis examines partial collapse, excessive deflection, instability and unexpected deformation. ENA2 reviews structural load paths, connections, material properties, design assumptions, construction or fabrication records and operating conditions to evaluate plausible root causes and contributing factors. Where warranted, nonlinear FEA can help assess local stresses, instability or connection behaviour against the documented failure pattern.
Fatigue & Vibration Failure Investigations
Repeated loading, equipment-induced vibration and pressure pulsation can cause fatigue damage in welds, connections and structural members. ENA2 reviews service cycles, crack locations, stress concentrations, support conditions and available vibration or operating data. Modal, dynamic or fatigue analysis can help examine resonance, cyclic stress response and fatigue-related mechanisms when appropriate inputs are available.
Material Degradation & Corrosion Assessment
Corrosion, localized pitting, section loss and material deterioration can reduce load-carrying capacity and alter stress distribution. ENA2 evaluates documented defect geometry, available material properties, exposure history and operating loads to assess the significance of deterioration. Structural calculations or FEA can examine local stress response and remaining capacity for defined conditions; inspection or material testing may be needed to establish reliable inputs.
Damage Assessment from Extreme Events (Blast, Impact, Natural Disasters)
Blast, impact, severe wind and seismic events can damage individual connections or affect the behaviour of a larger structural system. ENA2 reviews event information, observed distortion, fractures, displaced supports and potential load redistribution. Structural calculations and, where appropriate, explicit dynamic FEA help examine rapid loading, damage mechanisms and questions requiring further investigation. Repair or continued-use decisions require assessment of the actual asset and agreed scope.
Code Compliance & Remedial Design Evaluation
Forensic engineering consulting may include reviewing design drawings, calculations, fabrication records, as-built conditions and applicable codes or standards. ENA2 compares the relevant design basis with observed structural behaviour to examine possible deficiencies, undocumented changes and other contributing factors. Findings can guide further inspection, strengthening concepts or a separately defined remedial design assignment.
Our Approach to Structural Investigation
The investigation follows the available evidence and the questions defined in the project scope. Calculations and simulation are used to examine specific failure mechanisms, not to replace observations.
Define the Concern
Identify the affected asset, reported event and questions to be answered.
Review the Evidence
Examine drawings, inspection records, photographs, material data and operating history.
Apply Engineering Analysis
Use calculations, structural analysis or FEA where they can test defined mechanisms.
Evaluate Root Causes
Compare calculated behaviour with observed damage and consider alternative explanations.
Report Findings
Document methods, assumptions, uncertainties and recommended next steps.
Why Choose ENA2 for Forensic Engineering & Consulting?
Engineering Analysis Grounded in Evidence
ENA2 combines structural engineering review with targeted FEA to examine load paths, connection behaviour, material condition and credible failure mechanisms. Our forensic engineering analysis documents the assumptions and limits of each assessment, so project teams can determine whether inspection, testing or remedial design work is needed.
Who We Serve
Our forensic engineering and consulting services support asset owners, industrial operators, engineering and maintenance teams, contractors, insurers and legal professionals evaluating structural damage, failures or performance concerns.
Forensic Engineering Expert Witness & Litigation Support
Forensic engineering analysis can provide technical findings for insurance claims, contractual disputes and legal proceedings. Depending on the engagement, reporting may address damage mechanisms, design or construction records, engineering assumptions and the evidence supporting each conclusion.
Expert witness opinions or testimony are separate services that require confirmation of the professional's qualifications, independence, jurisdiction and engagement scope.
Project Inputs & Investigation Deliverables
What to Share
Photographs, a short description of the event and any available drawings are sufficient to start a scope discussion.

- Recommendations for inspection, testing, monitoring or repair assessment
Forensic Engineering & Structural Investigation FAQ
What are the common signs of structural issues?
Unusual cracking, excessive deflection, displaced or damaged connections, corrosion, settlement and unexpected vibration can indicate a structural concern. The severity cannot be determined from appearance alone. A project-specific assessment is needed to establish what the observations mean.
How is the cause of a structural failure determined?
Structural engineers compare physical observations with drawings, construction records, materials and loading history. Calculations or FEA may be used to evaluate specific failure mechanisms. A forensic structural investigation can identify contributing factors, but the evidence does not always establish one definitive cause.
What types of structures can be evaluated?
The scope may include buildings, industrial steel structures, equipment supports, connections and individual structural components. Whether an asset can be assessed depends on the technical requirements, available information and agreed project scope.
How is the safety of a damaged structure evaluated?
Engineers review the damage, remaining load paths, support conditions, applied loads and available material information. Further inspection, calculations or testing may be required. A forensic investigation is not automatically an authorization for continued occupancy or operation; that decision requires an appropriately scoped assessment.
Can forensic investigations support insurance claims or disputes?
Yes. Forensic engineering and consulting reports can document damage, assess plausible mechanisms and explain technical findings for insurance or dispute review. Insurance coverage, liability and legal outcomes are determined separately. Expert witness testimony requires a specific professional engagement.
What does a structural damage assessment report include?
Depending on scope, a report can include the reported issue, evidence reviewed, observations, engineering methods, calculations or FEA results, findings, uncertainties and recommended next steps. Report requirements should be agreed at the start of the assignment.
How long does a forensic structural investigation take?
The schedule depends on site access, extent of damage, records, engineering complexity and whether testing or specialist assessment is required. ENA2 can discuss timing after reviewing the project details and defining the investigation scope.
Where can ENA2 provide forensic engineering services?
ENA2 is based in Calgary and supports engineering projects across Canada. Technical analysis for U.S. projects can be discussed on a case-by-case basis. On-site investigation, regulated engineering services and expert opinions depend on the relevant jurisdiction, professional authorization and agreed scope.
