How to Determine the Event Start Date in TIA Method

Every delay event has a story. From the moment a contractor can no longer proceed with the work until the issue is resolved, that timeline—known as chronology—is the foundation of entitlement.

Identifying the event start date is critical. It’s the exact point when planned work becomes impossible due to:

🔹 Discrepancies in specifications vs. drawings

🔹 Direct client or consultant instructions to change scope

🔹 Delayed approvals of submittals beyond contractual limits

🔹 Practical contradictions between specifications and site conditions

🔹 Late subcontractor nominations or missing information

Too often, consultants embed changes subtly—in RFI replies or material submittal feedback—hoping project teams miss the claim opportunity.

Without a clear chronology, those opportunities slip away.

Chronology transforms scattered events into a defensible claim narrative.

How do you ensure your team captures the true start date of every delay?
