📍 When to use this template
- When a site condition (like an unexpected rock or existing utility line) makes the original drawing impossible to build.
- Whenever the Client or Architect issues a new instruction that modifies the design.
- Typically initiated by the Site Engineer or Project Manager, then sent to the Design/Technical team for review and approval.

⚖ Compliance notes
- Helps substantiate claims for Variation Orders under FIDIC Sub-clause 13.1 (Right to Vary) and 13.3 (Variation Procedure).
- Provides necessary documentation for rate analysis of non-BOQ items as per CPWD Works Manual.
- Forms a crucial part of the 'As-Built' drawing documentation process.
- Essential for audit trails to justify deviations from the 'Good for Construction' (GFC) drawings.
