Form Requirement
Action requested
Acceptable entries / Guidelines
This Section is used, by the Supplier, to request specific changes to
Siemens Drawings (or Design Specifications). The format should allow
the Siemens Engineer, when a change is approved as submitted, to
simply copy and paste the requested Action into drafting instructions.
The section should normally identify and request a change “From” (the
current definition), then “To” (the proposed definition).
If a Drawing has Zones, identify the Zone where the proposed change is
located.
If a Drawing has multiple Sheets, identify the Sheet that is affected.
When requesting a Specification change, identify the Page and
Paragraph Number.
Example:
Siemens Drawing Number LW12345:
Change: Sheet 4, Zone D-4
From: 6.2435 - 6.2465” O.D.
To: 6.24 - 6.25” O.D.
For more examples, see Appendix B.
