Marina City - The History and Restoration of an Iconic Facade

Abstract

<p>The twin towers of Marina City were the tallest reinforced concrete buildings in the world when they were completed in 1962. The design and construction of Marina City was an important milestone during the evolution of concrete high-rise construction during the 20th century, and the unique modern design served as a model for mixed-use developments that is still used today. The construction of the towers utilized innovative design and construction techniques. Significant concrete deterioration was identified on the facade in the 1990’s which presented challenges associated with performing concrete repairs on high-rise buildings. This paper reviews the history of the design, construction and restoration of these iconic towers.</p>
