Power & Renewable Energy HYDROELECTRIC DAM SPILLWAY EXPANSION

A 90-year old hydroelectric dam receives much-needed upgrades to allow for more discharge capacity and reduce local flooding.

INSIDE THE PROJECT

Å®ÓÅÒùÍÞÅàѵӪ Industrial used its broad-based hydropower construction experience to expand the spillway for an existing dam. Å®ÓÅÒùÍÞÅàѵӪ installed cofferdams, six piers and five slide gates. This unique project also included rehabilitation of the spillway facing concrete and rock anchor stabilization. Å®ÓÅÒùÍÞÅàѵӪ Industrial provided cost savings to the client early by pricing the project with a land-based approach, opposed to the original and more costly water-based design.

WHY IT MATTERS

Though it was not a flood control dam, this project was part of the licensing agreement with the Federal Energy Regulatory Commission which allowed for more water to flow through in the event of a major flood.  Å®ÓÅÒùÍÞÅàѵӪ’s land-based approach to expanding this nearly century-old dam delivered the project over 10 months early and significantly under budget compared to the original water-based design.
