BDI Structural Testing and Evaluation Services

BDI Services Overview

BDI offers efficient field testing and analysis services for evaluating all types of structures. Our personnel have performed over 250 tests all over the world and are familiar with many types of structural evaluation technologies.

We have pioneered the bridge load testing business with our Integrated approach that uses field data to calibrate a finite element model of the structure. The emphasis of this method is on efficiency in both the field and analytical phases, and can therefore be used on a routine basis.

BDI does not turn your project into a research effort as we stay focused on obtaining only the data that is required to answer the questions at hand.
