Altoona Dam Gate Pier Reconstruction

« Return to Project Search

Ayres’ dam inspection team found trunnion cracks and concrete spalls on the Altoona Dam piers and spillway ogee. Ayres completed the design and prepared plans and specifications for an epoxy injection project intended to re-establish the existing structural integrity of the radial gate trunnion pin piers. When the contractor started work, it was determined that the radial gate piers were too deteriorated for epoxy injection. Ayres recommended that the lake be drawn down to reduce the load on the radial gates and that the gate piers be repaired by removing the weak concrete and reconstructing the piers.
