In 2003 the Board of Direction approved therevision to the ASCE Rules for Standards Committces to govern the writing and maintenance of standardsdevelopedby the Society.All such stanards ar developed bya consensus standards processmanagedby the Society's Codes and Standards Commiteea balanced standards mittemade up of Society (CSC).The consensus process includes balloting bymembers and nonmembers balloting by the memberhpf theSocietyas a wholeandballotingbythepublicAll standards arupdated rreaffme ythe same process at intervals not excceding five ycars.
