Technical Committee

The URM Technical Committee made recommendations for:

  • The appropriate definition of “unreinforced masonry building”
  • Technical aspects of the mandatory retrofit program, including
    • The standard to which URM retrofits must comply
    • The size, location, and type of earthquake to be considered in developing the standard
    • Building elements to be addressed
    • Considerations for previously-retrofitted buildings; how to assess a building retrofitted to an earlier standard

The committee finished their work in 2010 and a final report is available with the proposed retrofit standard.
