Nesbitt Dam is one of the primary sources of drinking water for the cities of Wilkes Barre/Scranton and as with all raw water supplies, extreme care and diligence was required during construction. This project consisted of the drilling and installation of 25, 54 strand anchors totaling 2,182ft. Five anchors were placed in the non-overflow section, five anchors were installed to tie down an RCC training wall, and 15 anchors were installed in spillway, where artesian conditions of up to 65ft of hydrostatic head had to be met and overcame. The temporary shoring aspect entailed the design and installation of a 40ft exposed height wall that consisted of driven H-pile and wood lagging, with three rows of tiebacks. Additionally, 124 H-piles totaling 5,600ft were driven in the existing stream bed for a new training wall foundation.
