Scope of Project:
This project involves the installation of 150 high capacity rock anchors to upgrade the stability of the existing dam. With rock anchors as deep as 275 feet and the close proximity of adjacent anchors, drill tolerances of 1:150 are required so that the rock anchors do not intersect one another. Brayman shall utilize directional drilling techniques to satisfy such tolerances.
The project also includes the design and construction of two temporary soil nail walls, excavation and placement of 13,000 cy of embankment and the extension of 3 penstocks. |
