Confluence on Third

Des Moines, IA
Confluence on Third is a luxury apartment building in downtown Des Moines. Precast concrete hollowcore plank, beams, columns, and solid slabs were used to create this 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 standard inverted T-beams were also needed for the steps. Through the use of precast hollowcore plank, we were able to create an opening on two levels to give easy access for the tower crane.

The building adds 211 market rate housing units in a growing neighborhood. It features a rooftop patio with raised garden boxes, courtyard pool, fitness center, bike repair room, electronic car charging station, dog washing station, and bocce ball court.
