Clear, defensible delay expertise for formal disputes — from a practitioner who has planned the projects, not just reviewed the files.

Credible evidence starts with credible experience

Tribunals don’t decide delay disputes on volume of paper — they decide them on whose analysis they believe. Credible delay evidence is independent, methodologically sound, and communicated so that a non-programmer can follow every step. That is the standard Vertx works to, grounded in 25+ years of building and managing programmes on live UK infrastructure.

Services

Expert advisory (pre-appointment) — Early, privileged assessment of the strengths and weaknesses of your delay position before formal proceedings — often the most valuable money spent in a dispute.

Adjudication support — Rapid-turnaround delay analysis and reports suited to the 28-day adjudication timetable, where most UK construction disputes are actually decided.

Supporting appointed experts — Rigorous analysis, programme forensics and report support working under lead experts on larger matters.

Expert reports — Independent written opinion on delay, prolongation and programming matters for use in dispute proceedings.

Why appoint Vertx

Practitioner credibility — Opinions grounded in how projects are actually planned and delivered on roads, rail, HS2, bridges and nuclear — which shows under scrutiny.

Contract-literate analysis — Evidence framed around the legal tests the tribunal must apply — causation, concurrency, the prevention principle — not just the mechanics of the software.

Genuine independence — As a boutique, we carry no institutional conflicts across dozens of live framework relationships. Conflict checks are fast and clean.

One analyst, start to finish — The person instructed is the person who does the analysis and writes the report.
