CTLGroup was retained to conduct a comprehensive facade and gallery roofing condition assessment of the iconic University Hall, a 28-story reinforced concrete building located on the UIC campus. The condition assessment consisted of a document review, field investigation, laboratory examinations, and field mock-up trials. CTLGroup prepared repair documents and is currently providing construction administration and observational services to the client.
In order to provide durable repairs to the building, CTLGroup conducted materials testing of concrete samples to determine material compatibility between existing and repair materials. Based on the results, we developed trial concrete mixture designs for the facade patching and repairs. The trial mixture designs were evaluated for durability properties, and for color and texture match to the existing concrete substrate. The trial concrete mixture designs served as the starting point for the repair contractor’s approved concrete mixture design. Lastly, our firm assisted RATIO Architects with the evaluation of the windows to determine the extent of the repairs needed to replace broken glass lites.
