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.
