The Impact of Seismic Strengthening and Code Related Issues in Restoration, Renovation, and Re-Use of Historic Buildings
The need to reconcile seismic strengthening and other code-related issues with historic preservation objectives poses a variety of challenges for the design professional. A thorough knowledge of the local, state and national regulatory contexts, along with an understanding of two underlying principles, equivalency and life safety, provide a necessary framework for undertaking renovation projects. Two case studies involving important Los Angeles historic buildings, the Wiltern Theater and Grand Central Square, illustrate the complexities of code compliance with respect to preservation and programmatic goals, specifically in the areas of seismic retrofit, fire-life safety and disabled access. Successful historic preservation projects can benefit from a thorough pre-design phase and an experienced project team. Modifications and refinements to regulatory procedures, particularly at the local level, could also significantly facilitate restoration, renovation and re-use of historic buildings.
