TIA & Delay Claim Support

CPM Pros prepares time impact analyses and delay claim support in Primavera P6 for general contractors and trade contractors requesting a time extension, and for owners reviewing one. Send the baseline, the updates and the change documents; a fragnet TIA and written report come back on a quoted date. The analysis answers who caused the delay, how much time it added, and whether it was excusable, compensable, or concurrent.

Who This Serves

For owners, attorneys,
and GCs with claims

Construction delay claims require a scheduling expert who can defend the analysis methodology under cross-examination. We serve both sides of the negotiating table — owners defending claims and GCs pursuing REAs.

Using SmartPM or another analytics tool? Read checking a SmartPM half-step result before it goes in a time extension request and half-step analysis from both sides of the table. On civil and public works contracts, the extension request often starts with weather: see weather days on civil jobs, and how the schedule turns lost days into a time extension.

Questions GCs, Subs and Owners Ask
What is a time impact analysis and when is it required?

A time impact analysis (TIA) inserts the delay event as a fragnet into the schedule update in effect when the event occurred, then compares the project completion date before and after the insertion. The difference is the time the event added, and the analysis records who caused it and whether it was excusable, compensable, or concurrent. Most contracts require a TIA to support a time extension request or change order with time, and it is the method CPM Pros uses when there is a sound baseline and the delay events are known.

What documents does a time extension request need?

The approved baseline, every schedule update from the baseline through the period of the delay, the change orders, RFIs, daily reports, meeting minutes and correspondence that record the delay events, and the contract clauses on notice, float and time extensions. CPM Pros builds the fragnet in native Primavera P6 from that record and delivers the TIA report with methodology, findings, exhibits and exportable XER files, so the request can go to the owner, a mediator or an arbitration panel in the same form.

Can CPM Pros prepare the TIA for a subcontractor’s extension request?

Yes. Electrical, mechanical and civil contractors send the GC’s schedule updates, their own scope and the record of the delay event; the fragnet is built against the GC’s schedule so the request shows the effect on the trade’s work and on project completion. The same report supports a request to the GC or a pass-through claim to the owner.
