Project highlights
Their challenge
These buildings are located in the heart of Chicago’s iconic State Street Corridor. The client engaged our team to design and redevelop the five-story building at 100 S State Street to be an office and retail space fit for the surrounding retail, office, residential, and university demand. In addition, the client asked our team to provide designs for the new, three-story being built to replace the recently demolished connected building on 112 S State Street. Our team provided full mechanical, electrical, plumbing, and fire protection engineering design services on these two reconstructed buildings.
Our solution
To meet the challenge, our team developed an engineering design plan and provided construction administration for the renovation of the first building and reconstruction of the connected building. In order to meet our client’s unique design needs, our team’s design for the five-story 100 S State Street included three different spaces: a basement level tenant storage space, three floors of retail tenant space, and two floors of office tenant space.
The results
Our engineering design and construction administration successfully met the client’s goals for key program space layout and efficiency. Formerly two buildings, this new space is now referred to as 1 W Monroe Street. As a result of our personalized attention to detail, the client has seen quick results, already leasing out approximately 75% of the newly reconstructed space to nationally recognized tenants, including New York-based WeWork.
