Rehabilitation of Herbert Hoover Dike at Lake Okeechobee

open for bidding

Florida 6/21 The U.S. Army Corps of Engineers is seeking bidders to rehabilitate portions of the Herbert Hoover Dike at Lake Okeechobee. The work will include in-place abandonment and removal of the existing Herbert Hoover Dike Culverts KI-1 and KI-2, respectively, and the construction of new water control structures S-266 and S-265 at the respective adjacent or existing locations. The structures will include cast-in-place reinforced-concrete foundations, headwalls, and box culverts. Combination flap-and-slide gates will be installed at the lakeside headwall of each structure and dual leaf gates on the landside headwall of S-266. S-266 will be constructed on the north side of the existing KI-1 structure and will require installation of only an earthen cofferdam on the lakeside to dewater the construction site. The existing canal at KI-1 will be backfilled, and the structure will be abandoned in place upon completion of S-266. S-266 will consist of two 7-ft by 7-ft culverts with approximate barrel lengths of 100 ft. Demolition-reconstruction efforts for S-265 will require installation of lakeside and landside earthen cofferdams to dewater the demolition-construction site. S-265 will consist of one 6-ft by 6-ft culvert with an approximate barrel length of 100 ft.
