Incremental Seismic Rehabilitation of School Buildings (K-12) (Fema 395 / December 2002)

This manual is intended to assist school administration personnel responsible for the funding and operation of existing school facilities across the United States. This guide and its companion documents are the products of a Federal Emergency Management Agency (FEMA) project to develop the concept of incremental seismic rehabilitation?that is, building modifications that reduce seismic risk by improving seismic performance and that are implemented over an extended period, often in conjunction with other repair, maintenance, or capital improvement activities. The manual was developed after analyzing the management practices of school districts of varying sizes located in various seismic zones in different parts of the United States. It focuses on the identified concerns and decisionmaking practices of K-12 public and private school managers and administrators. Earthquakes are a serious threat to school safety and pose a significant potential liability to school officials and to school districts. School buildings in 39 states are vulnerable to earthquake damage. Unsafe existing buildings expose school administrators to the following risks: Death and injury of students, teachers, and staff; Damage to or collapse of buildings; Damage and loss of furnishings, equipment, and building contents; Disruption of educational programs and school operations. The greatest earthquake risk is associated with existing school buildings that were designed and constructed before the use of modern building codes. For many parts of the United States, this includes buildings built as recently as the early 1990s. Although vulnerable school buildings need to be replaced with safe new construction or rehabilitated to correct deficiencies, for many school districts new construction is limited, at times severely, by budgetary constraints, and seismic rehabilitation is expensive and disruptive. However, an innovative approach that phases a series of discrete rehabilitation actions implemented over a period of several years, incremental seismic rehabilitation, is an effective, affordable, and non-disruptive strategy for responsible mitigation action. It can be integrated efficiently into ongoing facility maintenance and capital improvement operations to minimize cost and disruption. The strategy of incremental seismic rehabilitation makes it possible to get started now on improving earthquake safety in your school district. This manual provides school administrators with the information necessary to assess the seismic vulnerability of their buildings, and to implement a program of incremental seismic rehabilitation for those buildings.
