As one of the largest bridge consultants in the United States, Michael Baker offers comprehensive services associated with the analysis and load rating of highway bridges of all types and complexities. We offer unique capabilities to help agencies manage the analysis and rating of large bridge inventories using the AASHTOWare Bridge Rating™ (BrR), formerly known as Virtis®, software, developed by Michael Baker and continuously supported, enhanced and maintained by our bridge experts. In addition, we have extensive experience with the load rating of unique, complex bridges that cannot be load rated with BrR or other conventional software packages. Our engineers have also developed user-friendly automated tools for complex bridges, such as arch, cable-stayed and suspension bridges, that allow owners to quickly load rate and evaluate permits for any user-defined vehicles, saving time and money and enhancing safety.
