6.0 Project Discussion:

There are a total of five Trunnion Girders in this project. Each trunnion girder has caps located around the perimeter. Please see attached drawings for cap locations. The concrete cap covers prevent potential corrosion of the prestressing bars in the trunnion girder.

The trunnion girders are best accessed from above. A government approved method of access is required to access the trunnion girder cap sealants. The chosen method shall be in compliance with the US Army Corps of Engineers (USACE) EM 385-1-1 Safety and Health Requirements. The trunnion girders are not accessible from the non-overflow section (left embankment) and are accessible by catwalk from the powerhouse or stairs from the roadway. Access to the girders must be obtained by a catwalk, climbing a ladder, and going up stairs to the pier. Photos are provided in

Part 13 of this scope of work.
