FIRST Premier Bank opened its new headquarters in April of 2021 in downtown Sioux Falls, SD. The seventy-seven thousand square foot building has an attached two-level, 56-space parking ramp. Structural columns, beams, slabs and double-tees allowed for an above ground, main level parking deck while supporting one level of underground parking.
The five-story headquarters stands tall and has changed the cityscape of the downtown area. Due to the building height, designers and engineers developed unique shear wall base connections for large wind loads. Gage Brothers produced reinforced slabs that had a large amount of steel in them to support the bank’s vault.
Construction started with six levels of structural precast shear walls at the elevator and stair towers. This was followed by five levels of sandblast and light etch finished architectural panels, as well as multiple angled diamond and polished granite stone clad panels on the main building. The use of precast elements helped ensure the project was completed on time during a pandemic.
Through careful communication with the construction managers, Gage Brothers coordinated the daily deliveries of precast panels, navigating around large commercial equipment and working within the limited drop off space available.
