The purpose of this project is to repair seven (7) existing water control structures on Quivira National Wildlife Refuge. Six of the seven structures (58A, DCH, DCF, DCC, F2, and D1) were built decades earlier and have corrosion, rust damage, and concrete cracking/spalling along the stop log channels (sides) , the intermediate stoplog channel (middle), and concrete box riser. The contractor will remove all rusty metal channels, fill existing wall and flooring stop log guides with concrete, construct/fabricate and install new stainless stop log channels per specifications, and repair cracked/spalling concrete to increase the efficient use and longevity of the structures. Water control structure (80 B) was newly constructed in 2019 but built 9 inches short due to a design error. The contractor will use the existing design plans from the original project increasing the height of the structure by 9 inches by forming and pouring concrete on top of the existing concrete board riser and wingwalls. A void on the front side (bottom) will also require less than 1 yard of concrete fill. Aside from increasing the height of the structure, no other steel or concrete damage repairs are required on 80 B.
