Corps adds $24.4 million to Tuttle Creek Dam contract

The Corps of Engineers said it will use $24.4 million from an economic stimulus bill to add to an existing contract for work on the Tuttle Creek Dam foundation project in Kansas.

The Corps announced May 6, 2009, it will add the funds to a contract previously awarded to Treviicos South Inc., Boston, Mass. Tuttle Creek Dam is included in a list of Corps projects released April 28 to receive a total of $4.6 billion from the stimulus package. (HydroWorld 5/4/09)

In awarding a $50 million general contract to Treviicos in 2005, the Corps said work at Tuttle Creek represented the largest ground modification effort in the world involving an operational dam, and the largest dam safety modification project the agency had tackled. (HydroWorld 5/9/07)

The $200 million program includes activities to stabilize sands beneath the 157-foot-tall, 7,500-foot-long rolled earth and rockfill embankment dam, and structural modifications to 18 spillway gates. All construction associated with the dam safety assurance program is expected to be completed in 2010, the Corps said.

Without the improvements, the Corps said, a 5.7 to 6.6 magnitude earthquake could inflict significant damage to the dam. Thirteen thousand people live downstream of the dam. Located on the Big Blue River five miles north of Manhattan, the dam is part of a multipurpose project operated by the Corps’ Kansas City District.
