BDI pioneered accurate bridge evaluation services in the late 1980s using field data to refine analytical models. Since then, we have solidified our industry-leading expertise in diagnostic testing, structural monitoring, and NDE of roadway, railway, and pedestrian bridges of all types and materials. We have developed purpose-fit instruments and innovative technologies for heavy civil applications, specifically bridges. This includes diagnostic tests for the purpose of load rating and performance testing, structural monitoring for performance evaluation, nondestructive evaluation for in-situ material performance, just to name a few.
