Project Overview

Originally constructed in 1989, Canal Station in Illinois was built with a durable precast concrete facade that has stood the test of time. In 2024, renovations and modifications were completed to update the building while maintaining its structural integrity.

A key component of the renovation involved modifying 35-year-old precast concrete facade panels to accommodate larger window openings. Despite their age, the panels remained in good condition, and structural analysis confirmed that even with a reduced section, they retained sufficient capacity to support design loads.

To ensure the structural performance of the modified panels, Wiss, Janney, Elstner Associates, Inc. (WJE) utilized finite element modeling, demonstrating that the enlarged openings could withstand code-required gravity and wind loads without additional strengthening. In instances where modifications impacted gravity or lateral supports, WJE engineered new, unique connection supports to maintain stability and performance.

Canal Station serves as a prime example of how aging buildings can be refreshed and upgraded without full facade replacement, showcasing the longevity and sustainability of precast concrete.
