Answer key to FEMA IS 8.A Building for the Earthquakes of Tomorrow: Complying with Executive Order 12699 Test Answers included. We cannot escape the threat of an earthquake, but we can mitigate the damage caused by using building codes that ensure structures that are built to withstand an earthquake. That is the purpose of Executive Order 12699: to prepare our communities. Other guides you may be interested include our FEMA IS 323 Answers Guide, FEMA IS 325 Answers Guide, and FEMA IS 393.B Answers Guide.
Since the Earthquake Hazards Reduction Act was passed in 1977, many actions have been taken to improve seismic safety. Executive Order 12699, “Seismic Safety of Federal and Federally Assisted or Regulated New Building Construction,” signed by President Bush in January 1990 is a significant Federal seismic risk reduction action. This Executive Order requires all new Federal, federally assisted, and federally regulated buildings to be appropriately seismic resistant. Among new construction affected are all buildings financed, either partially or fully, with Federal grants or federally guaranteed loans.
Because this Executive Order is so wide reaching, covering everything from single-family dwellings to large Federal complexes across the nation, a training course was needed to provide the tools, information, and planning guidance for those people affected by the Executive Order. The purpose of this course is to provide individuals in State and local governments, and the building and financial industries, with information about the requirements of the Executive Order and how they will be implemented. The course is also intended to provide the student with basic knowledge about earthquakes and how buildings can be built to be safe during an earthquake.
