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.

** March 1, 2006: Software temporarily unavailable until update process is completed **

The Applied Technology Council (ATC) is pleased to announce the immediate availability of the ATC-20i Mobile Postearthquake Building Safety Evaluation Data Acquisition System (Version 1.0). This personal digital assistant (PDA) application has been developed to facilitate the collection and management of postearthquake safety inspections of earthquake-damaged buildings using the ATC-20 procedures released by ATC in 1989 (ATC-20 Report, ATC-20-1 Field Manual) and updated in 1995 (ATC-20-2 Report). The ATC-20i PDA application enables engineers and building officials to complete the ATC-20 rapid and detailed evaluation forms in the field, print posting placards in the field, and submit the data electronically to the ATC server, where it is stored and tabulated for use by the jurisdictions affected by the earthquake. The application operates on PDAs using Palm Software.

The ATC-20i PDA application is available in two versions: (1) a licensed version that is licensed annually for a small fee; and (2) a freeware version that allows data acquisition in the field, without the possibility of transmission to the ATC server (the freeware version expires after 30 uses). To purchase the software license, go to our online store, under Product Index select ATC-Reports: Building Seismic Hazard Mitigation; then select Postearthquake Damage and Safety Evaluation of Buildings. Here you will find all ATC''s guidelines and related materials for postearthquake evaluation and repair of damaged buildings, including the ATC-20i cost and licensing procedure. Upon verification of your purchace, you will receive an e-mail containing specific instructions for downloading the software, and a temporary password, which you may change after installation.

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.
