— In many cases, construction sequencing or other existing infrastructure restrictions provide little room and especially airspace for the construction of piles.

Tampa International Airport Red Side Expansion Hensel Phelps Construction Co. contracted A.H. Beck to install the drilled shaft foundations for their Red Side Terminal expansion at Tampa International Airport. A.H. Beck was tasked with installing 145 drilled shafts, varying in diameter, with depths ranging from 15 to 80 feet socketed into Florida Limestone. There were many challenges posed on the project due to congested work areas, dense utility networks, and low overhead restrictions. Beck utilized one of their CAT based drill rigs tailored for low headroom and demanding rock excavation techniques to install the foundations.  Learn More Miami SR 836 Bridge Working with Archer Western – De Moya Joint Venture, A.H. Beck installed drilled shaft foundations for Miami's SR 836 Signature Bridge, a project for Miami-Dade Expressway Authority and FDOT. The shafts were located underneath and between the existing bridge spans in the Miami river and had to be accessed via trestle. Using the CAT based Beck 250 drill rig, they placed 48-inch diameter 90-foot deep shafts between the existing bridge structure adjacent to the existing bridge foundations. To protect the existing structures, full-length temporary casing was advanced with an oscillator through the sand and limestone layers. Learn More
