Danny's Construction performed the structural and miscellaneous steel erection for the new United States Courthouse.  The 2,600 tons of structural steel was erected using two tower cranes.  The congested downtown site posed its challenges, and because of the building's radius and glass front, strict tolerances were critical to the layout and erection of the structure.

Other construction challenges on this project included: placing free standing pipe columns of 103' before tying them in at the eighth floor; over 600 CJP moment welds; and a 12' cantilever walkway requiring engineered temporary erection aids to support 77' long 30,000 pound walkway beams spanning the structure's atrium.
