Our Expert Witnesses Serve As Active Practitioners And Our Practitioners Serve As Expert Witnesses

As a result, our testimony is informed by practical field experience, and our field practice is informed by anticipating issues that may arise in a legal setting.


We Strive To Make The Complex Understandable

Our aim is to teach, communicate, illustrate and convey our ideas as clearly as possible. Our visualization specialists provide graphical supports by developing models, renderings and animations that accurately and precisely present mechanics and mathematical calculations.


There Is No Substitute For Relentless Critical Thinking

We keep delving until we are certain we have command of the relevant facts. We use scientific approach and advanced analytical tools to validate our fundamental understanding of a problem. We begin our investigation by developing an understanding of the problems, constraints and desired outcomes and then apply our advanced modeling capabilities for simulation and illustrative purposes.


We Don’t Go Home Until The Job Is Done Properly

In emergency response work, we maintain a 24/7 presence on-site to ensure safety. And in our deconstruction work, we make sure it’s all down before we leave a job site.

Forensics projects

Forensic Tools

Software Development

Thornton Tomasetti develops software to solve challenging engineering problems. Examples include the Flex family of finite-element codes, including Onscale; VistaMat, for advanced material modeling; and FacilityBlast VCE, a fast-running computational fluid dynamics tool that accurately predicts vapor-cloud explosion loads.

Forensic Tools

Custom Animation

We use applied mathematics and mechanics to simulate physical events and determine their controlling parameters. Graphical animation visually re-tells an event, and visualizations convert the mathematical outcomes into something we can see and more easily understand.

Forensic Tools

Data Collection

We use laser scanners, thermal cameras, structural monitoring data- acquisition equipment and other sensors to obtain critical information on the behavior, position and condition of the structures and components under examination. Handheld devices enable us to collect and process data in real time with mapping technology. We are also well-versed in process data analysis to characterize the variation of critical data.

Forensic Tools


We use FEA to understand and model the behavior of structural systems and components, gases, flows and multi- body interactions, evaluating complex conditions and communicating the scientific facts using advanced engineering-simulation tools.

Forensic Tools


We developed a better way to manage and analyze data in a 3D or 4D model. Data is linked to model components for easy retrieval, keyword queries and statistical analysis. Our FIMs can quickly generate reports and visualizations for clear, persuasive communication of complex technical issues.
