Braddock Gated Dam

This project utilized two large precast float-in segments for the base of the new dam (265’ & 333’ lengths) with extensive use of precast elements and fabrication of segments at an offsite casting facility. The Bergmann team designed drilled shaft foundations, sheet pile cut-off walls with H-piles and pipe piles, river dredging, underwater tremie concrete placements, piers, trunnions and tailrace structures for the new $122M dam. Innovative construction methods allowed the dam to be built without the use of cofferdams for cost and schedule savings, as well as reduced river impacts.
