We review entitlement, build the event and notice chronology, assess the time the records support, and show where evidence is missing.
In a free 30-minute call we discuss your issue and deadline, identify the records needed to scope the work, and confirm whether Solvix is a good fit. Detailed review and analysis are scoped separately.

EOT rejected, reduced or awaiting assessment? We review entitlement, build the event and notice chronology, assess the time the records support, and show where evidence is missing.
Solvix International prepares and assesses extension of time claims for contractors, subcontractors, employers, developers, project managers and legal teams. We work under FIDIC 1999 and 2017, NEC3 and NEC4, JCT, Saudi government contracts and bespoke forms, and check every notice and time bar before the analysis starts.
The assessment links each delay event to the contract clause that gives entitlement, the notice that was given, the critical path in the Primavera P6 or Microsoft Project updates, and the records that prove it. You receive a clear report with the days supported, the days at risk and what is needed to close the gaps, ready to submit to the engineer or employer or to use in negotiation.

Assess excusable, compensable, and non-excusable delay events by reference to the contract, project facts, and schedule effect.
Review notices, instructions, approvals, access constraints, design release dates, and site records to determine whether procedural and substantive requirements have been met.
Support claim preparation, claim defence, independent determination, adjudication, mediation, arbitration, and litigation with clear, decision-ready outputs.
An extension of time assessment is a coordinated review of contractual entitlement, delay causation, programme criticality, contemporaneous records, notice compliance, and mitigation. Solvix approaches EOT matters with both a project-controls lens and a disputes lens so the analysis is commercially practical and technically robust.
Review late handover, restricted access, and unavailable interfaces against the planned sequence and milestones.
Assess delayed design releases, approvals, responses, or employer-supplied information against critical activities.
Assess suspension, instruction delay, utilities, third-party constraints, and authority approvals.

EOT requests are often rejected or reduced because the link between the event, the programme, and the contract is not clearly shown. We assess each step of that link on the records available.

Preparation or review of extension of time requests before submission to the employer or contract administrator.
Independent assessment of a submitted EOT claim to support a fair determination.
Review of the reasons given and of whether additional entitlement can be supported.
Assessment of whether the extension supported on the records removes or reduces delay damages.
Assessment of entitlement where the contract has sectional completion or key dates.
Review of subcontractor time claims and their consistency with the main contract position.
Was the event covered by the contract as a relevant event, relevant
matter, compensation event, or equivalent entitlement trigger?
Did the claiming party comply with notice provisions, particulars
requirements, and update obligations, or is there a time-bar issue to address?
Did the event affect the critical path or a milestone that actually
controlled completion at the relevant time?
What part of the claimed delay is attributable to employer risk, contractor
risk, neutral events, or concurrent causes?
Was the mitigation response reasonable, and were alternative work
fronts or resequencing genuinely available?
What period of extension, if any, is supportable on the records and
methodology used?
Our methodology is built to withstand scrutiny from project stakeholders, contract administrators, expert teams, and dispute forums. The precise approach varies by contract form, available records, and programme status, but the core logic remains consistent: establish the contractual basis, identify the event, test schedule effect, consider concurrency and mitigation, and issue a reasoned opinion.
 Identify extension of time provisions, notice mechanisms, compensation links, and contractual tests.
Review the accepted baseline, updates, progress snapshots, and milestone logic relevant to the event.
Align notices, instructions, approvals, minutes, and correspondence into a factual timeline.
Test whether the event affected completion directly and whether float or alternate sequence changed the outcome.
Consider overlapping causes, pacing arguments, mitigation steps, and acceleration measures.
Issue an independent conclusion on entitlement and highlight strengths, weaknesses, and key risk points.
Strong EOT opinions depend on the quality of project records. We work with the available record set while also identifying evidential gaps, conflicting narratives, and procedural weaknesses so clients understand both the strength of the time case and the vulnerabilities that may be challenged.
An extension of time assessment is an independent review of whether project delay events entitle a contractor or subcontractor to additional time under the contract. It considers the contract wording, notices, project records, programme effect, critical path, concurrency, and mitigation.
An EOT assessment is useful when an extension request is being prepared, reviewed, defended, negotiated, or determined, or when delay issues may later develop into adjudication, arbitration, or litigation.
Not always. Some matters can be assessed through a focused contractual and programme review. More complex disputes with contested causation or multiple overlapping events may require deeper delay analysis.
Key records usually include the contract, accepted programme, programme updates, notices, instructions, progress reports, design release information, approval logs, meeting minutes, site records, and delay-event correspondence.
Yes. The same structured methodology can be applied to prepare a claim, evaluate a submitted claim, respond to an opposing position, or advise on the strength of the time case before formal proceedings.
EOT assessment focuses on time entitlement under the contract. Delay analysis may provide a deeper programme-based view of causation and critical path effect, while disruption analysis addresses productivity loss and inefficiency rather than only completion delay.
The review of the contract, notices and records usually takes two to three working days. The delay analysis and draft EOT claim usually take two to three weeks for a typical building project. Larger projects or many delay events take longer, and we confirm the timetable in the written scope.
Notice requirements and time bars differ by contract and applicable law. Under FIDIC 2017, for example, the contractor must give notice within 28 days of becoming aware of the event. We review the notices that were given, the contract terms and the records, set out the risk clearly and work with your legal advisers where needed. See our guide to EOT notice and claim periods.
