Quantum turns on what the contract actually permits and what the records prove. Our quantity surveyors value the work, test the claim and quantify what is genuinely recoverable.
This is one of the specialisms within our construction expert witness practice.
In construction & engineering, the difference between a strong case and a weak one often comes down to whether the expert truly understands the sector. Generalist opinion rarely survives scrutiny on specialist questions, and a tribunal gives little weight to evidence that misreads how construction & engineering actually works. We focus here precisely because the issues are technical, the stakes are high, and the wrong expert is an expensive mistake.

FAQ
Common questions
What does a quantum and final account expert witness do?
They give independent, objective opinion to a court or tribunal on quantum and final account issues within construction & engineering, with an overriding duty to the court under CPR Part 35. The opinion usually takes the form of a written report and, where required, oral evidence.
When should I instruct a quantum and final account expert?
As soon as the issues are clear. Early instruction helps you test the strengths and weaknesses of the case, scope the evidence proportionately and avoid a rushed report against a deadline.
How do you select experts for quantum and final account matters?
On substance: relevant qualifications, genuine construction & engineering experience and an understanding of an expert's duties in litigation and arbitration. Where an expert has limited experience of giving evidence, we say so.
