13、he Board of Direction approved revisions to the ASCERules for Standards Committees to govern the writing andmaintenance of standards developed by ASCE. All such stan-dards are developed by a consensus standards process managedby the ASCE Codes and Standards Committee (CSC). Theconsensus process incl
14、udes balloting by a balanced standardscommittee, and reviewing during a public comment period. Allstandards are updated or reafrmed by the same process everyve to 10 years. Requests for formal interpretations shall beprocessed in accordance with Section 7 of ASCE Rules forStandards Committees, which
