Design and installation of 130′ diameter sheet-pile shoring for a 46 foot deep excavation. 92 pair of 75′ long sheet piles – each pair weighing over 10,500 lbs – interlocking together and driven vertically to grade to allow construction of a sewer lift station, and then removed after backfill of the structure. Two 100 ton DDF crawler cranes were used for the installation of the sheet piles.
