2、 revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This practice covers the concurrent use of relevantASTM standards for the preparation of elemental costestimates,summaries,and
3、analyses and specifically theirpresentation in a concise,consistent,and logical manner.1.2 While the style and directions use construction termsapplied to buildings,the principles apply equally well to otherforms of construction where appropriate elemental classifica-tions exist.1.3 This practice is
