The IABSE Working Group on Forensic Structural Engineering aims to examine and mitigate failures, improve the professional practice of forensic structural engineering, and facilitate the dissemination and application of failure information to structural design and construction throughout the world. This article is the second progress report on the evaluation of the Working Group's completed, and recently revitalized, survey of the forensic engineering practices in the IABSE member countries. The intent of the article is to familiarize the reader with the state of forensic engineering practices in the IABSE member countries, and urge the adoption of good practices by following the successful models of some of the countries.

<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>
