Drilled shafts (caisson) are often installed from temporary work platform at marine jobsites. Morris-Shea pioneered the use of double-wall sectional casing using the high torque available with our rigs to install “cased ahead” shafts. The cased ahead construction method removes the need for slurries in many cases and results in less soil disturbance, giving higher unit shaft friction values.
