This is a great video from WSDOT visualizing all of the geotechnical instrumentation and survey monitoring being done in Downtown Seattle above the Bertha TBM for the Alaska Way Viaduct Replacement project. Soldata is the company WSDOT hired to manage the monitoring. I heard a great presentation by a Soldata representative and a member of the Seattle Tunnel Partners in charge of the instrumentation and monitoring from the contractor's side several years ago at an AEG conference. You can read more about the amazing Bertha TBM and some of the monitoring being done in my article. [Source: WSDOT YouTube Channel. Image: YouTube]
