Winfall-to-Trowbridge Transmission Line Foundation Design
In 2012, Dominion rebuilt their 115kV transmission line (T/L 64) that crosses the five-mile wide Albemarle Sound in North Carolina. GAI Consultants, Inc. designed the 24 foundations located in the waterway, which consisted of 35-foot long precast concrete pilecaps and 66-inch diameter prestressed cylinder piles. The pilecaps were designed for bending moment plus torsion from the steel H-frame structure base reactions, combined with wave loading. The unique challenge for this project was the design of the connections between the pilecaps and the piles to meet the fabrication and installation tolerances. The innovative solutions implemented into the design included the use of self-consolidating concrete to bond the piles to the reinforcing steel cages that projected 9′-6″ from the pilecap. The installation procedure required rotating the 80-ton pilecaps 180 degrees with a barge-mounted crane, and setting the pilecaps on top of the cylinder piles.
