Now Available! FEMA P-2090/ NIST SP-1254 Special Report

The joint FEMA P-2090/ NIST SP-1254 Special Report, Recommended Options for Improving the Built Environment for Post-Earthquake Reoccupancy and Functional Recovery Time, is available for immediate download.  This report was requested by Congress as part of the most recent National Earthquake Hazards Reduction Program (NEHRP) reauthorization, and is the work of a Committee of Experts including more than 30 individuals from federal agencies, nongovernmental organizations, private sector entities, disaster management professional associations, engineering professional associations, and professional construction and homebuilding industry associations.

The report provides options in the form of recommendations, tasks, and alternatives for improving the built environment to increase resilience and reduce the impacts of future natural hazard events.  It includes one overarching recommendation and six additional supporting recommendations. Across all recommendations, there are 17 tasks identifying necessary actions and nine possible alternative actions needed for implementation.  Finally, the report includes an assessment of the recommendations and describes a path forward for implementation.

The Applied Technology Council (ATC) and the City of Los Angeles Department of Building & Safety (LADBS) are pleased to announce the ATC-50 Seminar on Seismic Evaluation, Grading, and Rehabilitation of Single-Family Wood-Frame Dwellings, to be held January 17, 2002 in the City of Commerce at the Wyndham Hotel. The seminar is the capstone activity in the ATC-50 project, which was initiated by the City of Los Angeles Mayor's Blue Ribbon Panel because of the high financial losses resulting from damage to single-family wood-frame dwellings as a result of the 1994 Northridge earthquake. The purpose of the 1-day seminar is to provide participants with detailed information about the ATC-50 seismic evaluation, grading and rehabilitation procedures, including an overview of the pilot testing phase of the project in which 500 buildings were evaluated and graded using preliminary versions of the procedures, and 50 homes are being retrofitted.

The seminar program has been developed for building inspectors, contractors, structural design professionals, building officials, and representatives of insurance companies and financial institutions. Topics to be addressed include:

  • the ATC-50 Seismic Evaluation and Grading Procedures, which enable a certified inspector to evaluate a detached single-family wood-frame dwelling and assign a seismic grade, ranging from A through D. (Each grade represents an expected range of damage, expressed as a percentage of replacement cost, should the dwelling be subjected to severe earthquake ground shaking),
  • the ATC-50-1 Seismic Rehabilitation Guidelines, which provide prescriptive methods, simplified engineering methods, and fully engineered methods that, if implemented, allow the homeowner to improve the seismic grade, and
  • incentives for homeowners to participate voluntarily in the program (ATC-50-2 report, Safe at Home in Earthquakes: A New Earthquake Safety Program).

The seminar program will include plenary sessions and break-out sessions to provide a more conducive environment for questions and discussions about the new ATC-50 procedures. The seminar speakers, including local practicing structural engineers and building regulatory officials involved in ATC-50 developmental work, were selected by ATC for their technical expertise and their ability to convey technical information effectively to large audiences.

The seminar registration fee is $150 ($120 for ATC Subscribers) and covers copies of the ATC-50, ATC-50-1, and ATC-50-2 reports, luncheon, and coffee breaks. A late fee of $25 will be imposed on registrations postmarked or faxed after January 7, 2002.
