Since no ground water was present and two large clasts up to 3-ft diameter and UCS 35,000-psi were expected, they anticipated this trenchless crossing to be performed by either slurry microtunneling or hand-mining. Due to increased capabilities, Horizontal Boring LLC selected an Akkerman WM720-II Pipe Jacking System with a Rock DCH to tackle the alignment. The system greatly reduced daily operating costs over slurry microtunneling while significantly increasing productivity over hand-mine operations.
