Programme certainty for the UK’s most demanding infrastructure projects.
VERTX is a boutique planning and project controls consultancy, led by a delay analysis expert with 25+ years on UK infrastructure. Forensic delay analysis for claims and adjudication, construction planning support and project controls under NEC, JCT, FIDIC and bespoke forms — delivered personally by a senior specialist, not passed to a junior team.
Problems we solve
These are the situations VERTX is brought in to resolve. Find yours, then book a call.
Programme rejected or not accepted
The problem: The PM, Engineer or Contract Administrator has rejected your programme again, often with the same comments as last time.
How VERTX solves it: The programme is rebuilt against the contract’s programme requirements and each stated reason for rejection, then resubmitted with a clear narrative. Find out more →
Change and delay events stalled
The problem: Compensation events, relevant events or variations are sitting unassessed while time and money drift.
How VERTX solves it: Each event is set out in a programme-based submission under NEC, JCT or FIDIC, backed by the project records, so it can be assessed and agreed. Find out more →
Extension of time refused
The problem: Your extension of time has been rejected and liquidated damages are looming.
How VERTX solves it: A delay analysis method is chosen to suit your records, showing cause, effect and entitlement clearly enough that the other side has to engage with it. Find out more →

Adjudication notice received

Claim made against you
The problem: A large delay claim has landed and you need to know what it is really worth.
How VERTX solves it: A forensic review tests the claim’s logic, baseline and concurrency, so your response is based on evidence rather than assertion. Find out more →
Tender programme needed fast
The problem: The bid is due and there is no planner free to build the programme.
How VERTX solves it: A logic-linked tender programme, aligned with your method and prelims, that shows the evaluation panel the job can be delivered. Find out more →

Boutique by design. Senior by default.
When you appoint VERTX, you get the expert — not the brand. Every commission is led by our founding director, supported by a dedicated delivery team, with no layers between you and the person doing the analysis. That means faster mobilisation, straight answers, and advice shaped around your project rather than a standard template. It’s how planning consultancy should work — and it’s only possible because we’ve chosen to stay specialist.
Direct access
You deal with the director on every engagement. Questions answered in hours, not routed through account managers.
Tailored, not templated
Reports, programmes and strategies built around your contract, your records and your commercial position.
Depth where it matters
We bring 25+ years of experience across roads, rail and HS2, bridges, nuclear, energy and utilities — earned on site, not just in software.
What we do
Forensic Delay Analysis & Claims
When projects slip, the programme tells the story. We reconstruct events, apply recognised SCL Protocol methodologies, and build delay narratives that stand up to scrutiny — in negotiation, adjudication or litigation. Learn more →
Expert Witness & Dispute Support
Independent delay expertise for formal disputes — pre-appointment advisory, adjudication support, and expert reports, grounded in decades of hands-on planning. Learn more →
Planning & Project Controls
Tender planning that helps win work. Live project planning that keeps it on track. Claims planning that protects your position. Programmes that meet the contract’s requirements, whether NEC, JCT, FIDIC or bespoke. Learn more →
Data Centres
Programme, delay and dispute support for data-centre projects. Grid-connection dates, long-lead power equipment and commissioning built into the programme logic, with EOT and claims built on the contemporaneous record. Drawn from our energy, grid and M&E-integrated work. Learn more →
