Gilboa Dam Rehabilitation Named ACEC NY Diamond Award Winner
(NEW YORK, NY – November 5, 2015) – The Gilboa Dam rehabilitation has been named an ACEC-NY Engineering Excellence Diamond Award winner.
The completed dam rehabilitation restored all features to their original functionality, upgraded the dam to current industry criteria, and provided an enhanced dam safety monitoring and reporting system.
Cutting edge anchor technology included 80 post-tension rock anchors for spillway stability. These anchors consisted of 58 strands with more than 1,000 tons of service load per anchor – approaching the limits of technology, and are the highest-capacity rock anchors used to date in New York, equaled only by a few others worldwide. As part of the recent rehabilitation, an 52 additional anchors were installed to stabilize the west training wall, the east training wall, and the concrete end sill.
This achievement benefits New York City and the Schoharie Valley by protecting its 8,000 downstream residents and thousands of properties by strengthening the dam and improving its flood control capabilities. In addition, it will effectively provide safe drinking water to the millions of people that rely on the Gilboa Dam and Schoharie Reservoir for many decades to come.
The winners will be honored at the 49th Annual Engineering Excellence Awards (EEA) Gala, which will take place at the Waldorf Astoria in New York City on March 19, 2016. The winner of the Empire Award — an award given to the highest rated project in New York State — will be announced at the EEA Gala. All Diamond Award projects designed and built in New York State are in contention for the Empire Award.
