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.  

Call for Consultants

ATC is committed to building a workforce that is as diverse as the communities we serve. Are you interested in consulting? Join us!

The NEHRP Consultants Joint Venture, a partnership of the Applied Technology Council (ATC) and the Consortium of Universities for Research in Earthquake Engineering (CUREE), is developing a data repository to document and publish information collected after the 2010 Maule Earthquake in Chile for the National Institute of Standards (NIST). This work is being led by Purdue University. The effort has two objectives:

  1. document, preserve, and disseminate valuable data pertaining to affected engineered structures with properties similar to those of structures in the U.S.
  2. develop a framework that can be used to document key information about the structural response of building structures to future earthquakes.

The data repository will also serve as a prototype for NIST’s recently initiated multi-year project to create a digital archive of data related to natural and man-made disasters as well as failure studies. This initiative promises to significantly improve the ways in which engineers help communities to prepare against disasters and structural failures. The availability of systematically organized field data would enable better procedures to vet design and evaluation tools, providing structural performance data with less stringent limitations about scale and applicability than data obtained through experimental and numerical simulations.

The NEHRP JV asks that you consider contributing information to the data repository for the 2010 Maule Earthquake. All information provided shall be credited appropriately. We are interested in photographs, drawings, or sketches of buildings, building coordinates, information on soils at building sites, information on ground motion, annotations on damage level, as well as other information that may benefit our effort. The profession would gain much from your contribution.

Should you be interested in contributing to the database to benefit our profession, please contact This email address is being protected from spambots. You need JavaScript enabled to view it. and we will provide you with a set of instructions to facilitate the data transfer.

A Commitment to Ethics, Equity, Diversity, and Inclusion

As structural engineers, we frame our contributions to society through our professionalism and ethics in the duties we perform. In our practice, we serve society and are active participants in the fabric of the communities in which we live. As structural engineers, we cannot limit ourselves to solving only problems of science and engineering. Ignoring the social, economic, and political contexts surrounding our engineering work is a path to irrelevancy. Our active participation includes a moral obligation to right the social and ethical wrongs we observe.

Therefore, as part of our active strategic planning process, we will critically examine the ethical values, equity, and diversity present in our internal processes and practices related to our staff, clients, and consultants.  Please read our full statement here.


Recently Released Reports

September 19, 2017 Puebla-Morelos, Mexico Earthquake: Seismological and Structural Observations by the ATC Reconnaissance Team

The ATC-141 report documents the findings of the field team, including observation of earthquake effects for 70 buildings, microtremors recorded using monitoring instruments at 7 buildings, and a compilation of processed ground motion recordings from UNAM (National Autonomous University of Mexico) and CIRES (Center of Instrumentation and Seismic Records). This report also serves as a reference to two papers approved for publication in Earthquake Engineering Research Institute (EERI) Spectra Journal.


CEA-EDA-01,  Earthquake Damage Assessment and Repair Guidelines for Residential Wood-Frame Buildings, Volume 1 – General Guidelines

This two-volume series describes the process of identifying, evaluating, and repairing common earthquake damage in typical residential wood-frame houses and is intended to increase the efficiency, consistency, and reliability of the earthquake damage assessment and repair process. Volume 1 (CEA-EDA-01) is intended to be used by insurance claim representatives, building contractors, homeowners, and others familiar with construction and repair. 


CEA-EDA-02, Earthquake Damage Assessment and Repair Guidelines for Residential Wood-Frame Buildings, Volume 2 – Engineering Guidelines

Volume 2 (CEA-EDA-02) is intended to be used by structural and geotechnical engineers, and others with relevant technical experience. The Guidelines help users create a conceptual scope of repair for a wood-frame house damaged by an earthquake.

FEMA P-530, Earthquake Safety at Home

Half of all Americans live in areas subject to earthquake risk, and most Americans will travel to seismically active regions in their lifetime. FEMA P-530, Earthquake Safety at Home, shows readers why earthquakes matter where they live, and how they can Prepare, Protect, Survive, Respond, Recover, and Repair in response to an earthquake.
