About this file
This drawing package and solicitation are for a sluice gate installation project at the Lac qui Parle Dam in Minnesota. The work involves constructing a dewatering box and pier extensions with slots to serve as a new dewatering system for the structure. It will also replace the nine existing sluice gates and actuators with nine government furnished slide gates and actuators stored nearby. The solicitation was issued by the Department of the Army Corps of Engineers St. Paul District under number W912ES20B0012. The drawings show plans and details for installing sheet pile cutoffs, cofferdams, and concrete extensions to the existing piers to facilitate the work.
