When time is in dispute, the quality of the analysis decides the outcome. Vertx reconstructs what happened, why it happened, and what it’s worth — with methods a tribunal will recognise and an opponent can’t dismiss.

When you need us

Delay disputes rarely announce themselves. They build — a compensation event that stalls, an extension of time application that’s rejected, a final account gap that keeps widening. Whether you’re a contractor protecting entitlement or an employer testing a claim, the earlier the programme evidence is put in order, the stronger your position.

What we do

Delay analysis — Time impact analysis, windows analysis, as-planned vs as-built and collapsed as-built, selected and applied in line with the SCL Delay and Disruption Protocol. We choose the method the records support — not the one that flatters the claim.

Claims preparation & defence — Extension of time submissions, NEC compensation event quotations and narratives, disruption claims, and forensic reviews of claims made against you.

Programme forensics — Baseline validation, progress reconstruction from site records, critical path mapping, and identification of concurrent delay.

Dispute support — Analysis and reporting for adjudication, mediation, arbitration and litigation, working alongside your legal team.

How we’re different

Most forensic planning is delivered by large consultancies where the named expert reviews work done by a rotating junior team. At Vertx, the director who scopes your commission performs the analysis, writes the report and answers your solicitor’s questions. That continuity shows in the product — and it’s why our reports read as one coherent argument rather than a stitched-together file.

The junction of programme and contract

Delay analysis lives where programming meets law. Our analysis is built with the contractual test in mind from day one — whether that’s NEC Clause 63 assessment, JCT relevant events, or the burden of proof in adjudication — so the technical work answers the question the tribunal will actually ask.

Common questions

Which delay analysis method is best?

The one your records can support. The SCL Protocol describes six main methods; the right choice depends on the quality of your baseline, progress records and the stage of the dispute. We advise on this before any analysis begins.

Can you review a claim made against us?

Yes. Forensic review of an opposing claim — testing logic links, baseline integrity and concurrency — is a significant part of our work for employers and main contractors.

Do you work with solicitors?

Routinely. We support legal teams in adjudication, arbitration and TCC litigation, and can work under privilege at an early advisory stage.
