Check out the ARTBA 2021 Bridge Report Which shows that 220,000 US bridges need repair. The National Bridge Inspection Program (NBIS) sets inspection intervals for bridges according to certain criteria, and classifies bridge inspections into 5 types:
SenSpot™ Archive
SenSpot™ for Monitoring Timber Bridges
Wireless SenSpot™ can be used for monitoring Timber Bridge Structures: •Measuring strain/stress in timber by Wireless Strain Gauge SenSpot™ •Measuring vertical displacement and deformation under loads by Wireless Displacement SenSpot™ •Obtaining load rating for timber bridges by

Monitoring Settlement of a Retrofitting Concrete Beam at a Building
Project Preview A high rise building’s load bearing concrete beam, which is suspended over a top floor terrace, was slowly deflecting over time. A fix was created to hold the deflecting beam. The fix is steel beams

Steel Girder Bridge Case Study: Wireless Tilt (Bearing Rotation) and Wireless Strain Sensors on Steel Girder Bridge
Monitored Variables and Members: bearings rotation and strain in girders Bridge Structure: the steel girder bridge over the river consists 14 piers and 2 abutments. The bridge longest span is about 160 feet, and it is fracture

Scour Critical Bridge Case Study: Wireless Tilt, Wireless Water Level Sensors and Camera on Continuous Span Concrete Girder Bridge
Monitored variables and members: piers tilt (incline; roll and pitch), water level of the river under the bridge, camera Bridge Structure: The two west/east-bound bridges over river consists 7 piers and 2 abutments. Continuous span girder bridge

Monitoring Bridges Australia Concrete Bridges under extreme loads: Wireless Strain Monitoring
The transport of extreme loads or “superloads” (deemed anything greater than 200 tonnes) on large convoys is often necessary in Victoria, Australia. Considerable planning and assessment are undertaken by the state’s Department of Transport (colloquially known as

Resensys Installs Tilt and Water Level SenSpot Sensors on Trancas Creek Bridge in Malibu, CA
On November 14th and 15th, 2017, Resensys installed 6 SenSpot Wireless Inclinometers, SenSpot Water Level sensor and 2 SeniMax data loggers on Trancas Creek Bridge in Malibu, CA. Trancas Creek Bridge is a coastal, 100 foot bridge

Resensys wireless strain and tilt sensors on fracture critical US522 over Potomac River Bridge
Resensy’s wireless strain sensors (Strain SenSpot) and wireless tilt sensors (Tilt SenSpot) were used to monitor another fracture critical bridge in Maryland. The structural health monitoring based on Resensys SenSpot sensors system was deployed on bridge US522

Resensys Strain Monitoring System on SR-16 Clay County Culvert Florida
On November 21st 2016, a Resensys structural health monitoring system was deployed on SR-16 Clay County Culvert. The system consists of 4 high rate strain SenSpot sensors and one SeniMax data logger and remote communication gateways.

Resensys Adds More Strain SenSpots and Conducts Truck Test on Gold Star Memorial Bridge, Connecticut
In July 2016, AI Engineers was tasked by the Connecticut Department of Transportation (ConnDOT) to work with the Resensys team to add 8 more Wireless Strain SenSpot Sensors in addition to the 20 previously installed strain gauges. During this instillation
