Peoria and LaGrange Dams Composite Wicket Gates

The contract includes the design, fabrication, and supply of fiber reinforced polymer (FRP) composite wicket gates for the Peoria and LaGrange Dams located on the Illinois River. The composite wicket gates shall be manufactured with a vacuum assisted resin transfer molding process. The composite wicket gates will need to meet the fits and function of the current wooden wicket gates as used at the locks and dams. The Peoria wicket gate size is 197 inches long and 46 inches wide with a thickness of 9 inches. The LaGrange wicket gate size is 179 inches long and 46 inches wide with a thickness of 9 inches. There are 108 wicket gates at Peoria and 109 wicket gates at LaGrange, and the contract is set up with options to cover the quantity of wicket gates. The gates will need to be designed to meet the physical and engineering properties specified within the contract. The composite wicket gates will need to be compatible with the existing steel hardware used on the current wooden wicket gates. The primary composite materials must be commercial grade E-glass fibers and vinyl ester resin. Other resin additives such UV inhibitors, fillers, or pigments are permitted to meet requirements such as color and environmental protection. Upstream surface and edges will need to have protection for impact durability and abrasion resistance using ultra-high molecular weight polyethylene (UHMWPE) sheeting. The composite wicket gates are to be custom design and built items. Other than the steel hardware, the composite wicket color shall be yellow.
