⚖ Compliance notes
- Per FIDIC Sub-clause 20.1, EOT notice within 28 days of cause of action.
- FIDIC Sub-clause 8.4 lists eligible causes: instructed variations, unforeseeable obstructions, exceptional weather, force majeure, contractor's not-attributable delays.
- Schedule Impact Analysis methodology must be agreed: Time Slice, As-Planned vs As-Built, or Window Analysis.
- Concurrent delays (multiple causes) require careful apportionment — often the source of disputes.
- Engineer's determination per Sub-clause 3.5 is binding unless objected within 14 days.
- Cost component is separate from time — typically prolongation + loss of productivity claims.
