The Association of State Dam Safety Officials (ASDSO) has awarded the 2015 ASDSO National Rehabilitation Project of the Year Award to the Gilboa Dam Rehabilitation Project. ENR New York has also selected the Gilboa Dam project as the Water/Environment Regional Best Project. The Gilboa Dam impounds the Schoharie Reservoir, which provides approximately 14 percent of the water supply for more than 9 million people in New York City and the surrounding areas.
Owned by the New York City Department of Environmental Protection (DEP), the Gilboa Dam underwent a ten-year rehabilitation to restore all features to their original functionality, upgrade the dam to current industry criteria, and provide an enhanced dam safety monitoring and reporting system. In a joint venture with Hazen and Sawyer, Gannett Fleming was commissioned by DEP to provide engineering services for an interim stability and monitoring improvement project. This was followed by a comprehensive rehabilitation and facility upgrade. The work, which included eight construction contracts with a total value of approximately $200 million, was substantially complete by October 2014.
“The Gilboa Dam Rehabilitation Project provided many challenges for our team,” said Rodney Holderbaum, PE, PLS, National Practice Leader for Dam Engineering at Gannett Fleming. “Our engineers faced each task with expertise and innovation, culminating in solutions worthy of these awards. Despite setbacks in the wake of Hurricane Irene in 2011, we were able to complete the project ahead of schedule and without service disruption.”
The ASDSO National Rehabilitation Project of the Year Award recognizes a unique remedial design that advances the state-of-the-art in the field of dam safety and exemplifies the professional engineering and construction standards that dam safety requires. The award is presented to the individual, company, agency, or organization whose project is judged to best represent those qualities.
The ENR New York’s Best Projects awards competition recognizes construction and design excellence in New York and New Jersey. The 2015 award-winning projects will be highlighted in ENR New York's November 16 print edition. ENR New York serves New York, New Jersey and Connecticut's annual $25.9-billion construction marketplace.
