Modern anchoring, shoring, and bracing techniques require specialized design and skills to implement successfully. There are multiple systems and solutions available to the industry, each with their own advantages and disadvantages. Understanding the different systems and their desired impact ensures they are working as designed and can be seamlessly integrated into the overall repair of the building. Learn from case studies on different systems used on existing and historic structures, including how to analyze and select each system type. Properly understanding these repair techniques is necessary to maintain and preserve historic structures and advance building preservation. One of the featured case studies includes the Old Joliet Prison, a compelling example of large-scale masonry stabilization in a historically significant setting.  **Learning Objectives:** - Identify typical structural failures in existing masonry buildings. - Summarize the stabilization options available for existing buildings. - Compare appropriate repair and stabilization options depending on structural type and conditions. - Describe how different stabilization approaches fit into the 4 approaches described by the Interior Secretary’s Standards for the Treatment of Historic Properties. ## About the Speakers ### Terry McDonald, SE, PE Principal, Klein & Hoffman ![Terry McDonald](https://info.imiweb.org/hs-fs/hubfs/Terry%20McDonald.jpg?width=300&height=300&name=Terry%20McDonald.jpg) With 24 years of experience in the industry, including 20 years with K&H, Terry brings a wealth of expertise, leadership, and a deep understanding of the firm’s mission and values to his new role. Terry joined K&H in 2004, rising from a project engineer to managing the firm’s structural engineering group, overseeing key projects, and contributing to the company’s strategic growth as a member of the firm’s board of directors.
