Low Cost Bridge Structural Monitoring Technology / Turning Structural Monitoring Data into Decision Making Information

This is a supplemental Phase II proposal submitted to DOT for additional funding and performance period extension of the on-going DOT Phase II project (contract # DTRT57-10-C-10027). The overall objective of the Supplemental Phase II effort is to complete the development of the sensor system capable of continuously monitoring the integrity of bridge structures, conduct field operation validation test of the developed prototype system on real bridges, and collect long term sensor data for evaluation of the system accuracy and reliability. These efforts are considered critical for further maturing the proposed technology and commercializing the prototype bridge health monitoring system. The intended use scenario of the developed system is to provide early warnings and decision support to bridge maintenance staff for possible damages on the bridge and assist them in prioritizing maintenance actions. The system will supplement the existing maintenance practice by providing continued monitoring capability between the bi-annual routing bridge inpsections required per National Bridge Inspection Standards.
