Description
Measure a supplied drawing-review round's signed age.
Construction records combine revisions, dates, dimensions, rental periods, claims and financial balances. Revision numbers need not be consecutive, calendar offsets differ from business days, and recoverable length can depend on a strict cutoff. A supplied approval or readiness label is a record assertion rather than an engineering inspection or contractual determination.
Measure a supplied drawing-review round's signed age.
When to use this tool
Use Shop Drawing Review Round Age when you already have roundSubmissionDate, evaluationDate and need to measure a supplied drawing-review round's signed age.
How to use the tool and how it works
- Enter roundSubmissionDate, evaluationDate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.

}Limitations and assumptions
- Negative gaps are retained. No document, review completion, revision validity or contractually appropriate turnaround is verified.
- 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.
Alternative or Complementary methods
Check controlled drawings, site measurements, schedules, approvals and the complete contract. Use the appropriate engineering assessment and actual billing or claim terms when a local scalar calculation or date comparison cannot establish suitability or entitlement.
