LINEA is a 35-story, 366,834 SF tower at 215 W Lake Street directly adjacent to an active transit line within the Loop of downtown Chicago. BASE performed value engineering of the post-tensioned slabs and vertical elements. Typical parking and residential levels were studied in detail using 3D finite element analysis to optimize the layout of the post-tensioned cables and mild steel reinforcement. Without impacting the design concept, structural performance, or space usage, a total savings of $450,000 was achieved.
BASE also assisted the construction team in devising a method to use the existing structure as support during the dismantling of the tower crane used to construct the tower.
