PacRim prepared PS&E for over 7,000 LF of 10” C900 water main to replace an abandoned 8” water line at NAWS China Lake. The design used the jack and bore method for construction within the Caltrans and Union Pacific Railroad (UPRR) right-of-way. At the water sections outside the Caltrans and UPRR right-of-way, conventional trenching and buried pipe were used in the design.
