Construction Defects & Delay Visualization

In construction disputes, our visualization experts help to illustrate complex delay, disruption, and defect issues in a matter that is easily understood:
 

Construction Defect Visualization
Our visualization experts develop graphics, models, and animations that depict the cause and effect of construction defect issues.


Construction Delay Visualization
The complexity of interdependence within construction schedules can be made clear through interactive timelines. This form of media is ideally suited to show when an event occurred visually and the subsequent impacts on the project.


These visualizations allow legal teams and experts to walk through voluminous data to highlight critical milestones, documents, concurrent delay impacts, and the progression of disrupted schedules in an organized manner, with the ability to move from one section of the project to another instantly.

Product Failure Analysis & Design Evaluation

In product liability cases, we provide detailed animations that communicate potential design issues, as well as the intended and resulting performance of a product, and how these design features and performance relate to the cause of an accident. This information helps simplify what happened, why, and how a design feature may relate to an accident in personal injury or property damage claims.
 

Design Evaluation Visualizations
We analyze and depict critical product design features, component interactions, and intended safety mechanisms. These visuals help demonstrate whether the design met applicable standards or failed to prevent foreseeable risks.


Product Failure Analysis
Our visualizations reconstruct product malfunctions, material failures, or misuse scenarios. These reconstructions help clarify the cause of failure and highlight the differences between as-designed and as-failed conditions.

Use of Force & Law Enforcement Incident Reconstruction

Use of force investigations often involve conflicting footage, fragmented narratives, and subjective eyewitness accounts. Our forensic visualization experts specialize in transforming material body-worn camera (BWC) footage, surveillance video, smartphone recordings, and photographs into grounded, easy-to-understand visual narratives.
 

Analytical Techniques
We conduct frame-by-frame video analysis and photogrammetry to clarify positioning, timing, and movements of individuals involved. These methods are particularly useful for analyzing officer-involved shootings, compliance disputes, crowd control incidents, and police procedure reviews, among other use cases.
 

Visual Formats
Following our analysis, the findings can then be represented in simple forms of animation, still graphics, or a virtual reality environment that allows a participant to have a real and precise experience of an event that has already occurred. Photogrammetric 3D analysis of 2D video and photographs also provides the viewer with the opportunity to witness the event from a different vantage point. This experience allows a better understanding of what happened at the time of the event and helps courts and investigative bodies better understand what occurred and assess the actions taken.

Medical Malpractice & Standard of Care Visualization

Medical malpractice cases often involve procedures that are difficult to explain using traditional documents or testimony alone. Our forensic visualization experts take the complicated details of a medical malpractice case and create clear, physics-based animations and 3D graphics that depict what occurred, what should have occurred, and where deviations from the standard of care may have taken place.

These visuals help clarify complex concepts including surgical techniques, anatomy, injury mechanisms, and provider actions—providing a powerful tool for explaining medical evidence to juries, legal teams, and insurance professionals. The 3D environment allows for unlimited access to what might otherwise be an occluded procedure or medical event.

Nighttime Visibility Studies

Cases involving questions about nighttime visibility require an understanding of the lighting conditions at the accident scene and the effect that this lighting had on the driver’s visibility of other vehicles, pedestrians, or objects. Our forensic visualization team performs scientifically grounded analyses to evaluate what could be seen, when, and under what conditions in low-visibility scenarios. These studies are essential in litigation involving pedestrian collisions, obstructed intersections, roadway lighting deficiencies, and perception-reaction time claims.

Our team is able to demonstrate visibility conditions at the time of the accident through the use of calibrated video, photographic equipment, and high-dynamic-range imaging methods, which help lay the groundwork for understanding what scene features were visible, and at what time during the accident sequence they became visible. Our visibility reenactment work has been accepted in court and shown to jurors throughout the United States.

Forensic Photogrammetry

Photogrammetry is the science of making reliable measurements through the analysis of photographs or video. This technology helps determine factors such as position, shape, distance, and characteristics of people, vehicles, or other objects visible in a video. Photogrammetry can play a critical role in the analysis of an event, and the speed, acceleration, position, and orientation of objects, people, and vehicles in a video or photograph.

Our experts have been using camera-matching photogrammetry and photogrammetric techniques for decades, publishing over 50 peer-reviewed scientific publications, classes, and books on the topic. We continue to lead the research in this area nationally. We use both traditional and advanced forms of photogrammetry to produce spatially accurate reconstructions and precise visuals that support litigation, insurance claims, and forensic investigation.

Our photogrammetry capabilities Include:

  • Single-image and multi-view photogrammetry
  • Reverse camera projection
  • Photo scanning and photo mapping
  • Camera-matching photogrammetry
  • Photographic projection

Property and Infrastructure: Visualizing Damage and Building Failures

When structures collapse or critical systems fail, visualizing the sequence of events can provide critical insight to reveal causation and impact.

Our visualization team works closely with in-house forensic engineers to recreate events such as building failures and collapses, equipment malfunctions, or property damage incidents, transforming data into scientifically accurate animations and illustrations.

These visual models are used in legal disputes, insurance claims, and investigative presentations to clarify the cause, extent, and duration of damage and clearly communicate the sequence of events, where and when failures originated, how they spread, and the resulting impact.

Fire Origin, Explosions, Combusion, and Wildfire Progression Visualizations

J.S. Held’s visualization team leverages a number of methods and techniques to analyze and visualize the origin, cause, and propagation of fires and explosions, including wildfires.

We use photogrammetry, photo analysis, video analysis, and the application of augmented reality to establish where the fire/explosion originated, what caused the fire/explosion, and to define a timeline of the event. These findings are shown in sophisticated, dynamic, and scientifically-based graphics, animations, and physical models.
