Each practice area is a deep discipline with its own methods, instruments, and literature — never a line item. Engagements routinely draw on several at once.
We determine how a collision happened — speeds, trajectories, sequence of events, and driver actions — from the physical evidence the crash left behind, not from anyone's recollection of it.
Conservation of momentum and energy methods, crush-based closing speeds, and yaw/skidmark analysis.
FARO Focus3D laser scanning, photogrammetry, and scaled diagramming that preserve the scene to millimeter precision.
Sight-distance studies, conspicuity analysis, and perception-reaction evaluation grounded in the research literature.
The bridge between the crash and the injury. We analyze occupant kinematics, restraint interaction, and injury causation — determining whether the forces of a specific collision could produce a specific claimed injury.
Comparing crash severity (delta-V, accelerations) against biomechanical tolerance data and the medical record.
How bodies move inside the vehicle during impact — seatbelt loading, airbag interaction, head strike, ejection risk.
BRi's own human-volunteer testing programs inform our analysis of the minor collisions other firms can only theorize about.
Component failures, product performance, and materials behavior — investigated with laboratory instrumentation and first-principles mechanics.
Fracture, fatigue, and deformation examination of failed components and systems.
Force, load, and material characterization via digital force gauges and university-grade Instron access.
Design, warning, and performance evaluation for contested products and equipment.
Mechanical analysis of industrial, elevator, and equipment-related injury events.
The engine room of the firm. BRi conducts independent research and instrumented testing programs whose data feeds every opinion we render — because the most defensible analysis is the one built on measurements we took ourselves.
Low-speed rear-end and frontal impacts with instrumented volunteers — real occupant response data.
Tri-axial accelerometers, load cells, speed traps, and datalogging meters — meticulously calibrated and ready for field deployment.
Thousands of NHTSA and IIHS crash tests, NASS real-world investigations, and the SAE literature — continuously updated.
Complex dynamics, made legible. Our forensic animations and visualizations translate reconstruction mathematics into exhibits a jury absorbs in minutes — every frame traceable to the underlying analysis.
Vehicle motion, occupant kinematics, and sight-line reconstructions rendered from measured data.
Scaled scene diagrams, time-distance charts, and demonstratives built for admissibility.
Event data recorders capture the seconds that decide cases — but only if imaged properly and interpreted honestly. BRi maintains current EDR tooling across makes, including the platforms most firms cannot read.
Industry-standard crash data retrieval with documented chain of custody.
Manufacturer-specific EDR access for vehicles the generic tools miss.
Delta-V, pre-crash data, and system states analyzed in engineering context — with the limitations stated plainly.
Send the essentials — parties, date of loss, what you need answered. A principal engineer eventually reviews every inquiry, with an honest assessment of whether we can help.
