CTL Group’s sensors and structural diagnostics team is to take part in a testing programme next month to determine how well the Homer Hadley I-90 floating bridge across Lake Washington in Seattle could support a proposed light rail transit line. Under a contract with long-time client KPFF Consulting Engineers, CTL Group will produce and install about 60 sensors and a wireless data acquisition system that will be used to monitor the behaviour of the bridge during live load tests. Heavily loaded flatbed trucks will simulate the weight and movement of light rail trains during the tests.
