Mechanical Engineering Expert Witness & Forensic Failure Analysis
Mechanical Engineering Failure Analysis for Litigation, Insurance, and Risk Management
Mechanical system failures can result in significant property damage, business interruption, personal injury, and complex litigation. Determining why a failure occurred requires more than identifying a damaged component—it requires a systematic engineering investigation grounded in physical evidence, accepted engineering principles, and scientific methodology.
Áreté Forensics provides forensic mechanical engineering services throughout Florida and nationwide. Our licensed mechanical engineers investigate equipment failures, evaluate compliance with applicable codes and standards, determine the origin and cause of failures, and provide independent engineering opinions for attorneys, insurance carriers, corporations, manufacturers, property owners, and governmental agencies.
Our investigations are designed to answer critical technical questions, including:
- What failed?
- Why did the failure occur?
- Were design, manufacturing, installation, maintenance, or operational deficiencies contributing factors?
- Did the equipment comply with applicable engineering standards and building codes?
- What engineering evidence supports the conclusions?
HVAC Forensic Engineering
Heating, ventilation, and air conditioning (HVAC) systems are among the most complex and expensive building systems, making them a frequent source of construction defects, property damage claims, commercial disputes, and expert witness litigation.
Our engineers investigate:
HVAC Design Evaluation
- Equipment sizing (Manual J, Manual S, Manual N)
- Airflow analysis
- Duct system performance
- Equipment selection
- Load calculations
- ASHRAE compliance
Moisture, Condensation, and Indoor Environmental Issues
We investigate excessive humidity, condensation, microbial growth, building-envelope interactions, inadequate ventilation, and improper dehumidification to determine the engineering causes of moisture-related losses.
Building Automation Systems (BAS)
Modern HVAC systems rely on sophisticated control systems. We evaluate:
- Sensor failures
- Control programming
- Sequence of operation
- Alarm history
- Trending data
- Equipment integration
- Control system performance
Commercial Mechanical Equipment
Our engineers analyze failures involving:
- Chillers
- Boilers
- Cooling towers
- Pumps
- Air handlers
- Rooftop units (RTUs)
- Compressors
- Variable frequency drives (VFDs)
- Mechanical room equipment
Mechanical Equipment Failure Investigations
We investigate failures involving commercial, industrial, institutional, and residential mechanical systems, including:
- Manufacturing equipment
- Industrial machinery
- Rotating equipment
- Conveyors
- Mechanical drive systems
- Hydraulic equipment
- Pneumatic systems
- Pressure vessels
- Process piping
- Facility mechanical infrastructure
Plumbing and Mechanical Piping Failure Analysis
Water damage remains one of the most common causes of residential and commercial property insurance claims. Determining the root cause often requires detailed examination of materials, installation practices, operating conditions, and maintenance history.
Our investigations include:
Pipe Failure Analysis
- Corrosion
- Dezincification
- Erosion corrosion
- Microbiologically Influenced Corrosion (MIC)
- Stress corrosion cracking
- Freeze damage
- Water hammer
- Manufacturing defects
Mechanical Components
Evaluation of:
- Pumps
- Valves
- Pressure regulators
- Backflow preventers
- Water heaters
- Pressure vessels
- Heat exchangers
- Expansion tanks
Plumbing System Evaluation
Our engineers determine whether plumbing systems were designed, installed, maintained, and protected in accordance with applicable engineering practices, manufacturer requirements, the Florida Building Code, and recognized industry standards.
Why Engineering Analysis Matters
Mechanical failures frequently involve multiple contributing factors rather than a single cause. Our role is to evaluate the available evidence using accepted engineering methodology and provide independent opinions supported by technical analysis.
Our investigations emphasize:
- Physical evidence
- Scientific methodology
- Engineering calculations
- Applicable codes and standards
- Objective documentation
- Clear communication of technical findings
When appropriate, advanced engineering tools—including finite element analysis (FEA), thermal analysis, computational modeling, and system performance evaluation—may be used to better understand failure mechanisms and illustrate engineering conclusions.
Frequently Asked Questions
What is the difference between an engineering inspection and a forensic mechanical investigation?
An engineering inspection evaluates the condition and performance of a system based on engineering principles. A forensic mechanical investigation applies scientific methods to determine the origin, cause, timing, and contributing factors of a mechanical system failure. These investigations are commonly performed for litigation, insurance claims, subrogation, and risk management.
How quickly can Áreté Forensics perform an inspection?
Mechanical failures often involve perishable evidence. We routinely perform time-sensitive inspections throughout Florida and can coordinate prompt site evaluations to document conditions before repairs, demolition, or evidence alteration occurs.
Do you handle product liability cases?
Yes. Our engineers investigate failures involving residential, commercial, and industrial products to evaluate whether engineering evidence supports the presence of defects in design, manufacturing, installation, maintenance, or operation, or warrants warnings.
Our Forensic Engineering Methodology
Each investigation is tailored to the circumstances of the loss while following accepted forensic engineering principles.
