Whether we’re investigating water intrusion, faulty fire systems, entire building collapses or other design and construction defects, we have the in-house expertise to deliver the answers you need.

  • Structural

At Thornton Tomasetti, we know that showing is often better than telling. With state-of-the-art simulation and graphical capabilities – including 3D/4D forensic information modeling and virtual reality simulations – we create vivid, clear-cut illustrations of problems.

And unlike many other firms, our expert witnesses work 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 improved by understanding issues that may arise in a legal setting.
