Detecting the beat of the bridge
SiWIM is the first commercially available bridge weigh-in-motion system in the world. The system is fully portable and can be installed in a single day without the need for a road closure.
SiWIM uses existing bridges to weigh vehicles and gather data used in bridge assessments.
Measurements are done with strain gauge sensors which are installed on the bottom side of the bridge, so no parts of the system are visible on the road surface.
