Description
Return a drawing prefix's supplied rank and revision number.
Construction bookkeeping distinguishes installed, accepted, credited and reworked quantities, as well as contractual cost and schedule conventions. A local variance or budget term can expose a gap without verifying work quality, payment entitlement or the project critical path.
Return a drawing prefix's supplied rank and revision number.
When to use this tool
Use Drawing Revision Prefix Order when checking a supplied construction quantity, charge, record or schedule convention.
How to use the tool and how it works
- Enter prefix, number, suppliedPrefixes. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read prefixRank, revisionNumber. Use the output convention below.
Return a drawing prefix's supplied rank and revision number. Require nonnegative whole number, unique suppliedPrefixes and a recognized prefix; prefixRank is its zero-based index.1

}Limitations and assumptions
- The vocabulary and order are supplied, not an industry revision standard or evidence that a drawing is current.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified project records, a complete schedule and governing contracts; involve qualified construction, engineering or legal professionals for practical decisions.
