Separate a rough opening, a finished opening and the required clear passage. Sending one unlabelled dimension can produce a door that does not suit the final floor or wall finish.
Practical Review Checklist
- Identify each opening on the plan and photograph it with its door mark; record the survey date and drawing revision.
- Measure width at more than one height and height at more than one position. Keep the readings, not only a selected minimum.
- Record wall thickness, material, visible irregularities and the agreed finished-floor datum. Note finishes not yet installed.
- Check plumb, level and diagonal relationships with suitable tools; flag discrepancies for design review rather than inventing an installation allowance.
- Separate surveyed values, design targets and dimensions still awaiting confirmation. Identify who authorises the manufacturing dimensions.
Record and Approval
Use a survey sheet with opening ID, reading positions, units, photographs, floor datum, unfinished work, surveyor and approver. A repeated reading that disagrees with the drawing is a hold point, not a reason to quietly amend the order. Obtain the selected manufacturer's frame and installation requirements before final sizing.
Send the door marks, quantities, destination and the completed review record to WONLY for a configuration-specific discussion. Confirm availability, evidence and responsibilities in writing; this checklist is not a product certificate or a universal installation instruction.
FAQ
Can this record replace the approved specification? No. It organises the questions; the responsible designer, supplier and installer must resolve the actual configuration before release.
