Late changes to a notch, opening or panel boundary can invalidate an otherwise clear cut-to-size grating order. Use a revision record to show what changed, which panels are affected and who approved the resulting fabrication instruction.
Define the release package
List the drawing number, revision, panel schedule and associated specification. Mark provisional dimensions as unresolved. A purchase order and an older sketch should not compete as production instructions; identify the document set the fabricator is authorised to use.
Describe changes in a reviewable format
- Panel mark: identify every affected panel and its quantity.
- Previous detail: record the replaced dimension or arrangement.
- New detail: provide the revised dimension from the stated datum.
- Consequences: review bearing bars, supports, edge treatment and fixing access.
- Commercial response: confirm any price or programme change.
- Release: record the accepted revision and approval date.
Use a specific change description
For example, a note saying move the pipe hole is incomplete. Identify the panel mark, the revised hole location and size, the drawing datum and any changed edge detail. Ask the responsible reviewer to confirm the effect on the panel arrangement before authorising fabrication.
Check work already in progress
Ask which panels have been cut, assembled or finished when a revision arrives. Distinguish a change that can be incorporated before fabrication from one requiring rework or replacement. Record the agreed treatment of superseded parts rather than leaving the workshop to decide.
Close the revision at delivery
Match the delivered panel marks and packing list to the final approved schedule. Keep the change record with the inspection documents so the installer can distinguish a deliberate revision from a fabrication error. See the cut-to-size workflow for the complete sequence.
