Award of Merit Interior/Tenant Improvement: Ivanti HQ

Abstract

The tenant reduced its office square footage and designated two floors of the original six floors for sublease. The design team pivoted to execute a revised design for the two subleased floors and rework the existing space for the original tenant. The interconnecting stair wasn't yet designed when key engineering decisions were made, such as placing sizing beams in the heart of the building during core and shell construction. As a result, engineers had to account for the assumed loads of the stair based on schematic concepts from the design team. The final design was a stair intended to be free-floating within the middle of a large floor opening with no visible columns or hangers from which mid-landings could be supported. Creative double cantilevers were used at mid-landings and expansion joints to account for seismic loads.
