In 2017-18 CMR Tech was engaged by the GFWA Trevi Joint venture to perform 3 static load tests on barrettes for the Forrestfield Airport Link Project.  At 3 different locations, Airport Central, Belmont and Bayswater Stations, 7-9 layers of strain gauges and extensometers were set up and tension tests were performed between 14 to 16 MN.  Over 50 channels of data were recorded to the data acquisition system.

4 x 500T jacks and 4 x 600T load cells used in the testing

9 extensometers were set up with displacement transducers to measure barrette movement
