The customer, Concurrent Technologies Corporation chose Chandler Monitoring Services Inc. as the System Integrator to design, install, and monitor the system. The system installation was completed in December 2010.

Objective

To monitor the integrity and behavior of the bridge structure, and effects due to high traffic and heavy truck loads that could cause possible damage & fatigue. This bridge application included several new features in the bridge application, including sensor activated cameras, a weather station, a solar power station, backup power supply and security features.
