A consortium made up of Tutor Perini, Zachry and Parsons is in charge of designing California's high-speed rail. Crews in the Madera, Calif., area are building a sensor-equipped rebar cage that will be dropped into a deep hole and then filled with concrete to allow engineers to test the load capacity. Also underway is demolition work on some Fresno buildings as part of the pre-construction activity.
