The Monument

Gage Brothers was chosen by Minneapolis-based Mortenson Construction, which is ranked by the industry publication Engineering News-Record as the 16th-largest contractor in the United States. Perkins+Will, JLG Architects, and Scull Construction round out the project team.

The nearly 250,000-square-foot arena is home to Rodeo Rapid City, Black Hills Powwow, Lakota Nation Invitational, and other sports and entertainment events. The facility features 12,500 seats, a variety of experiential and premium seating options, additional social spaces within view of the action, and open and transparent concourses.

The goals of the project were to provide the community and surrounding area with a building that has amenities they can enjoy for many years to come, as well as provide promoters with a venue that is functional, easy to use, and works with their show set-up. This includes a large arena floor, a minimum of 75 feet to the grid, an expansive rigging grid, a minimum seating capacity of 10,000 for an end-stage concert, a loading dock that can handle a 15 to 20-truck show, and a facility that is accessible for all.

61,000 square feet of smooth grey walls and slabs, 56,000 square feet of stair tread and risers, 24,000 square feet of insulated wall panels, and precast beams/columns took Gage Brothers a little over 100 days to manufacture in its new state-of-the-art plant in northeast Sioux Falls.
