Deformation Monitoring
Real-time 24/7 automated deformation monitoring of bridge and train tracks to measure stability
The Massachusetts Bay Transportation Authority (MBTA) completed a four-year drawbridge replacement project in Gloucester, MA. The first two phases of the project involved demolishing half of the existing bridge while the other side remained opened to trains.
Geocomp provided automated rail track and bridge deformation monitoring for the stability of the existing bridge while trains continued to run over the remaining working half of the structure. Automated motorized total stations (AMTS) were installed to measure the position of survey prisms clamped to the rail tracks while other AMTS units monitored the drawbridge, timber trestle, and abutments during partial demolition of the bridge and adjacent construction activities.
