Confluence on Third

Des Moines, IA
Confluence on Third is a luxury apartment building in downtown Des Moines.  The building includes 211 Studio, Junior Suite, One-Bedroom and Two-Bedroom apartment homes. It also features a courtyard with fire pit, outdoor pool & hot tub, dog run & dog wash station and bocce ball court. Precast was used to create a roughly one city block sized underground parking structure, as well as the podium for the building. Precast beams and columns were also used to create elevations for the courtyard. Deeper than usual inverted T-beams were also needed for the steps. We were able to create an opening with hollowcore on two levels to give easy access for the tower crane.
