ATC-20 Set Procedures for Postearthquake Safety Evaluation of Buildings & Addendum
The ATC-20 Set consists of two documents: the ATC-20 Report, Procedures for Postearthquake Safety Evaluation of Buildings, and the ATC-20-2 Report, Addendum to the ATC-20 Postearthquake Building Safety Evaluation Procedures. The ATC-20 Report was developed under a contract from the California Office of Emergency Services (OES), California Office of Statewide Health Planning and Development (OSHPD) and FEMA. (Published 1989, 152 pages). The ATC-20-2 Addendum, developed under a grant from the National Science Foundation (NSF), with funding provided by the U. S. Geological Survey (USGS), contains revised placards and safety assessment forms, based on ATC-20 use following the 1989 Loma Prieta, 1992 Cape Mendocino, 1992 Landers, 1992 Big Bear, and 1994 Northridge earthquakes (Published 1995, 94 pages).
