The Applied Technology Council (ATC), in cooperation with the Federal Emergency Management Agency (FEMA), is seeking proposals from U.S. engineering firms to conduct trial evaluations of older concrete frame structures using the methodology described in the ATC-78-3 Report, Seismic Evaluation of Older Concrete Frame Buildings for Collapse Potential (ATC, 2015), which was developed with FEMA funding.  Trial evaluations are being sponsored by FEMA to test the clarity and usability of the methodology, assess the level of effort required to implement, and determine if calibration is necessary. 

A complete description of the scope of services to be performed, required qualifications, submittal requirements, subcontract terms, selection criteria, selection process, and schedule are provided in the Request for Proposals (FEMA), available on the ATC website (  The report can be downloaded from the ATC website hereThe closing date for the submission of proposals is October 30, 2015.

The methodology described in the ATC-78-3 report is under ongoing development, and expansion of the methodology to address concrete wall systems is currently underway.  This solicitation is the second in a series of planned trial evaluation programs intended to inform future versions of the methodology.  The following additional solicitations can be expected: 

  • A future Request for Proposals funded by the City of Los Angeles Department of Building and Safety (LADBS), to be announced approximately one year from now, that will solicit the involvement of Southern California engineers to conduct a trial evaluation of the methodology for concrete wall buildings located in California.

Response and/or participation in one Trial Evaluation Program will not preclude response and/or participation in future programs.

More information about the ATC-78 Project Series is available here.


What's New?

What's New? The ATC Hazards by Location website allows the user to find site-specific basic wind speeds, ground snow loads, tornado design wind loads, and seismic loads used in the standards published by the American Society of Civil Engineers, National Earthquake Hazards Reduction Program, and International Building Code. This website was developed with the financial help of the ATC Endowment Fund, Federal Emergency Management Agency (FEMA), Insurance Institute for Business & Home Safety (IBHS), and Metal Building Manufacturers Association (MBMA), and is free of charge to users.
