The construction of 111 Main, a 25-story office tower, followed a parallel timeline with the George S. and Dolores Doré Eccles Theater, designed by a separate architect on a shared redevelopment site. The 111 Main design team developed an innovative solution to a complex site challenge: how to integrate the tower with the theater, which, for uncompromised functionality, required a significant part of the tower’s site footprint.
The design solution suspends the southern portion of the office tower over a section of the four-story theater, avoiding perimeter tower columns puncturing its space. The tower hat truss, the basis of the integrated solution, is brought forward and expressed as a structural crown. 111 Main features one of the world’s first innovative structural steel solutions to a complex site challenge – suspending the entire perimeter of a tower to achieve overhang at adjacent building.
