Time Impact Analysis (TIA)
Prospective and contemporaneous TIAs that show, with a clean fragnet and a statused update, exactly what an event does to completion.
Measure the impact now, while it can still be agreed.
A time impact analysis models a defined event, typically as a fragnet inserted into the update current at the time of the event, and measures what it does to completion and key milestones. Many contracts require one before time is granted, and done well it is the fastest route to agreeing an extension while the project is still live.
For contractors we prepare TIAs that meet the contract's procedural requirements and anticipate the reviewer's questions on logic, float and mitigation. For owners we review submitted TIAs line by line, separating genuine impact from optimistic logic, sequestered float and duplicated events, so you grant what is due and can explain why.
What we bring to Time Impact Analysis (TIA)
Senior practitioners, proven method and the right technology, specified line by line.
Fragnet design
Event activities and ties drafted to reflect what actually changed.
INCLUDEDUpdate selection
The correct data date and status used as the starting point.
INCLUDEDImpact measurement
Effect on completion and contract milestones calculated precisely.
INCLUDEDFloat & mitigation
Available float and reasonable mitigation considered openly.
INCLUDEDSubstantiation
Narrative and evidence assembled to meet the contract.
INCLUDEDIndependent TIA review
Owner-side review of methodology, logic and reasonableness.
INCLUDEDA clear path, milestone by milestone.
Every engagement follows a disciplined sequence, so you always know what happens next and why.

Technology we work in
Platform-fluent and vendor-independent. We work inside your environment, or recommend the one that fits.
What changes when we arrive.
Not activity. Results your board, your lenders and your teams can feel.
Extensions settled during delivery, not argued years later.
Requests that satisfy the contract the first time.
Owners grant what is warranted, and only that.
What leaders ask us first.
Straight answers. If yours isn't logged here, raise it with us directly. A principal will respond.
When should a TIA be prepared?
As soon as practicable after the event, in line with the contract's notice and submission periods. Late TIAs lose credibility and sometimes entitlement.
What exactly is a fragnet?
A fragment network: a small set of activities and logic representing the event or change, inserted into the schedule so its effect on the critical path can be measured.
Can you review TIAs our contractor has submitted?
Yes. Owners regularly retain us to review contractor TIAs for method, logic, float use and reasonableness, and to draft a response that can be defended.
Extension of Time (EOT)
Preparation, assessment and negotiation of extension of time claims under AIA, ConsensusDocs, FIDIC, NEC and bespoke contracts.
Forensic Scheduling
Reconstruction and analysis of as-planned and as-built schedules from the project record, with every finding traceable to its source.
Claims Support
Preparation, review and defense of delay, disruption, acceleration and change claims, with entitlement, causation and quantum aligned.
Command the date you announced.
Book a 45-minute program review with a senior principal. You will leave with an independent read of where your schedule and cost really stand, and the three moves that matter most.
