The prominent office building at 55 East Monroe, overlooking Millennium Park, had its upper floors converted in 2008 to a condominium residences. The lower eleven floors provide parking to the residents, visitors and tenants of the building. The parking structure underwent a major renovation in 2008 at the time of the condominium conversion, and additional maintenance repairs were performed in 2016.


Professional Services

In 2008, due to excessive deterioration the repair scheme consisted of removing the top 3-inches of deteriorated concrete slab to be replaced with a bonded structural concrete overlay and new top steel reinforcement. This project also included reinforcing isolated portions of the parking garage to meet today’s concrete code standards. Some of the challenges included keeping the retail space beneath the parking decks and tower above the garage open throughout; meeting amended code issues; substantial testing of aggregates; and keeping the maximum number of parking spaces available. In 2016, to maintain the performance of the parking structure, some limited follow up repairs were performed.

K&H coordinated and developed a repair strategy, performed extensive quality assurance testing, and coordinated ongoing exchange of information between all team members. K&H also performed construction administration services to observe construction and to oversee necessary field adjustments, and to coordinate services. This project received a 2008 Award of Excellence: Parking Structures Category from the International Concrete Repair Institute (ICRI). The follow-up repairs involved similar services in terms of developing repair documents and observing construction.
