A.H. Beck installs shafts for a dock on Topsail Island Bridge in Surf City, North Carolina.
Overview:
Overall, the foundation consists of 108 shafts measuring 48 inches along with 68 shafts measuring 60 inches. Plan depths vary from 90 feet to 117 feet. The shafts were constructed with polymer slurry due to the soft clays and silts. A. H. Beck successfully completed two Osterberg Load Tests, which allowed NCDOT to shorten some of the plan lengths while affording a considerable cost savings to the Owner.
