This service can be delivered as proactive commercial governance on live projects, an independent review of a troubled cost position, or a targeted verification exercise linked to payment, change, funding, audit, or dispute concerns.
In many construction disputes, the challenge is not simply the absence of data but the absence of structure. Critical information is spread across correspondence, schedules, notices, progress updates, payment records, meeting minutes, instructions, and technical documents. Solvix helps turn that fragmented material into a disciplined narrative and evidence base that legal teams can work with effectively.
A credible TIA depends on using the right update, modelling the event realistically, and explaining why the inserted impact is reasonable. We do not rely on generic software outputs in isolation. Instead, we combine schedule mechanics, project records, and contractual context so the result is understandable and robust.
A disciplined prospective method for evaluating delay events against the current accepted schedule
Identify the relevant accepted programme update, status date, calendars, critical path, and programme assumptions.
Review instructions, notices, RFIs, design releases, procurement issues, access constraints, and event chronology.
Model the delay event using realistic relationships, durations, constraints, and resource-driven sequencing where justified.
Integrate the fragnet into the update closest to completion, milestones, and float effects.
Evaluate whether the event affected the critical path, concurrent issues, excusable delay, and extension implications.
Issue a transparent narrative, schedules, assumptions, and outputs suitable for project teams and dispute forums.
We also explain the assumptions behind the selected update, fragnet structure, progress status, and any limitations in the available records. That transparency is important because many TIA disputes turn not on software operation, but on whether the model reasonably reflects the real event and the accepted programme at the time.
Core elements usually expected in independent construction expert reporting
Define the question, scope, and assumptions.
Show the records and data relied upon.
Explain how the analysis was performed.
Set out the material results and observations.
State the conclusion clearly and independently.
Our methodology is designed to move quickly from diagnosis to action while keeping the recommendation credible. The exact approach depends on the maturity of the programme, reporting quality, contract environment, and urgency of the issue, but the core sequence remains consistent.
confirm the current programme position, major slippage events, reporting quality, and milestone exposure.
establish the live driving path, near-critical paths, and major handoff constraints.
build practical options for date recovery, including resequencing, parallel working, resource changes, and workface strategy.
check constructability, labour availability, procurement constraints, site access, quality, HSE, and commercial implications.
select the preferred option and define actions, responsibilities, trigger dates, and monitoring requirements.
Where appropriate, Solvix can also coordinate TIA findings with wider delay analysis, EOT assessment, disruption review, contractual entitlement review, and quantum support so clients receive one coherent position rather than isolated technical outputs.
A TIA is a prospective delay analysis method used to test how a specific event affects the current accepted programme by inserting a fragnet or impact model into the schedule update closest to the event.
It is commonly used for extension of time assessments, live project claim administration, responses to submitted EOT claims, and contemporaneous decision-making before a dispute matures.
No. TIA addresses the schedule effect of an event. Contractual entitlement still depends on the wording of the contract, notice compliance, causation, concurrency issues, and other project facts.
Yes. We can review the selected update, fragnet logic, assumptions, status data, and interpretation used by another party, then identify strengths, weaknesses, and alternative views.
Yes. TIA often forms part of a wider package that may include EOT assessment, forensic schedule analysis, claims support, expert reports, or arbitration and litigation support.
TIA is usually prospective and contemporaneous, testing the expected impact of a live event on the current programme. Forensic schedule analysis is often retrospective and is commonly used after events have unfolded.
Yes. A well-explained TIA can help parties narrow disagreements about schedule impact, milestone movement, and the scale of time relief before matters proceed to more formal dispute stages.
