Designation: E 1804 – 96 An American National Standard
Standard Practice for
Performing and Reporting Cost Analysis During the Design

Phase of a Project
This standard is issued under the fixed designation E 1804; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
