Getec install two number horizontal Shape Accel Arrays at 125 m long in Los Angeles

Working with our colleagues at Hayward Baker on the regional connector site in downtown Los Angeles, Getec installed two number horizontal SAA to lengths of 125 and 116m . These  lengths beat our last record in Australia where we installed 100m lengths for embankment monitoring. The SAA were installed in two directionally drilled boreholes that followed the route of the two intended TBM's. The SAA will provide data on ground movement above the TBM. The install took a day and the data is running on our site specific app and our control software gtcVisual . The SAA will be in place  for 18 months and then extracted for re - use by the Client.
