Salt River Project - Mid-Rise Infill Building

Tempe, Arizona

As one of Arizona’s largest utilities, the Salt River Project (SRP) began harnessing the Salt River and generating power from it in 1911.   The five-story Mid-Rise Infill project is the latest expansion of the SRP Headquarters facility in Tempe, Arizona. The expansion ties into the existing construction on three sides and is limited to the story heights of those existing conditions. This expansion will be used as swing space for four more phases of renovation to the existing building. The need for wide open flexibility of future users lent itself toward a bidirectional steel moment frame lateral system and large bay sizes. Buehler provided multiple options to optimize the steel solution and keep the design-build team on budget.
