BDI pioneered accurate bridge evaluations 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 test for the purpose of load rating, structural monitoring for performance evaluation, nondestructive evaluation for in-situ material performance, just to name a few. RAILWAY
