County Materials-Johnson Davis — Johnson Davis installing 24 inch RCP in Fort Pierce utilizing County Materials pipe the backfill while also improving safety . While the July 20th discussion centered on lifts above the springline of concrete pipe , ultimately The proposed lift thickness specification option could be considered for both concrete and plastic pipe pending review of 12-inch lift case studies throughout the state , supporting pipe embedment national standards and engineering for the pipe-soil structural interaction . Next steps include reworking the amendment language to the specifications and then testing the lift thickness in the field to demonstrate that densities can be achieved with 12-inch lifts above the springline . Our goal is to have the new lift thickness specification finalized by November in order
