Moose Creek Dam modification

open for bidding

Alaska The U.S. Army Corps of Engineers is currently evaluating submissions from firms capable of providing the necessary labor, materials and equipment to carry out a modification project to the Moose Creek Dam in North Pole. The project involves constructing a mix-in-place barrier wall in the embankment of the dam at the Chena River Lakes Flood Control Project. This will consist of constructing 4.5 miles of barrier wall 56 to 66.5 ft below the crest of the dam embankment with Portland cement and bentonite. The barrier wall is expected to be between 18 and 30 in. wide. Sheet pile will be driven around the low point drain and control works to have a continuous wall through penetrations in the embankment. The intent of the barrier wall is to sever a continuous fine grained sand/silty sand that is highly erodible under the embankment material. The 8.1-mile-long dam was built in 1981 and protects Fairbanks and adjacent communities from floodwaters.
