Our History


What began as university research became the foundation of one of the premiere providers for diagnostic testing, infrastructure monitoring, and nondestructive evaluation in the world. This occurred during the early stages of the personal computer and was a result of hard work, creativity, persistence and of course living “under bridges”.

Bungee Jumping 1990

Bungee Jumping


Once formed, one of BDI’s first projects consisted of recording data for a startup company that offered bungee jumping from hot air balloons. The testing system was configured to record data from the gondola supports to ensure an adequate factor of safety was being maintained. An FAA representative oversaw testing, and payment consisted of eight free bungee jumps.

Long-Term Monitoring

Long Term Monitoring

Based on experience gained through all of the temporary field testing, BDI began installing equipment for longer-term data collection.


Supporting Research Efforts 1991 - Present

Supporting Research Efforts


Many of BDI’s first projects consisted of supporting research institutions by conducting field tests on highway bridges and providing data for specialized analysis. Soon, railroad bridges and river control structures were also being added to the project list.

Developing & Manufacturing Hardware

Developing and Manufacturing HardwareAlso, during this exciting period, development began of a new “modular” testing system to be manufactured and sold to clients to complete their own testing. The experiences gained by developing this new “Structural Testing System(STS) launched another entire revenue stream for the company that led to providing systems and training around the country and world. China became the largest STS customer, with many other countries soon being added as customers including Australia, Thailand, and Malaysia.

Developing Safety Programs

Developing Safety Programs

Critical to completing the field testing, several safety programs needed to be developed specifically for construction, highways, railroads, and river control structures since they are all under the jurisdictions of different agencies. Ropes access program has been developed which has required a great deal of specialized training for project personnel. A very large and comprehensive program was developed which is still followed and periodically updated.
