About this file
This drawing package and solicitation provide details for a sluice gate installation project at Lac qui Parle Dam. The project involves constructing a dewatering box and pier extensions with bulkhead slots to serve as a new dewatering system. The work also includes replacing nine existing sluice gates and actuators with government-furnished slide gates and actuators stored nearby. The drawings show plans and sections for installing a temporary cofferdam system using sheet piles and structural members. Notes specify installation sequences and component requirements. The solicitation was issued by the Department of the Army Corps of Engineers St. Paul District for contract W912ES20B0012 to replace infrastructure at the dam.
