The ITR report notes there are no active fault crossings in the Delta conveyance alignment and that seismic demands are not extreme compared to other projects, and DCA indicated it agreed on that statement. Why are we building tunnels if seismic issues are not a concern?
June 12, 2020What is the power source for the tunnel cutter head?
June 12, 2020As currently proposed, the maintenance shaft sites would only be sized to remove the cutter head. The launch shaft sites would be sized to lift the segments into the tunnel, for tunnel boring machine trailing gear and for reusable tunnel material handling and storage. The large launch shaft site would only be required every 12 to 15 miles.
