A.H. Beck installs 36 drilled shafts up to 170 feet deep at Bayport Container Terminal at the Port of Houston's wharves 4 and 5 in Houston, Texas.
McCarthy Building Companies contracted A. H. Beck to install 36 drilled shafts measuring 36-inch diameter by 170-foot deep at the Port of Houston’s wharves 4 and 5 at the Bayport Container Terminal. The shafts will be used as anchor points for a crane tie down system to accommodate the ports new 158 feet tall cranes. Once shaft locations were saw cut and decking removed, the shafts were installed by first anchoring templates to the existing deck. An oversized piece of temporary casing was then attached to the template and served as a guide for the 91-foot pieces of 42-inch diameter permanent casing. The permanent casing had to be installed though an existing erosion protection system in 70 feet of water. The shafts were drilled to depth using a crane attached drill rig and bentonite slurry due to the soft alluvial materials found in this area.
