The Dubai International Financial Centre (DIFC) has become one of the region's most active seats for resolving high-value construction, infrastructure and energy disputes. Whether a case is administered by the Dubai International Arbitration Centre (DIAC), heard under ICC rules with DIFC as the seat, or litigated before the DIFC Courts, one feature is now standard in almost every substantial dispute: the quantum expert witness.
Why Quantum Experts Matter in DIFC Disputes:
Construction and infrastructure disputes in the UAE rarely turn on liability alone. Once responsibility for a delay, defect or termination is established, the tribunal or court still has to answer a much harder question: what is the claim actually worth? That is the domain of the quantum expert — typically a forensic accountant, quantity surveyor or valuation specialist who translates factual and contractual findings into a defensible monetary figure.
In DIFC-seated arbitrations, quantum experts are almost always party-appointed rather than tribunal-appointed, reflecting the common law heritage of the DIFC Courts and the influence of the IBA Rules on the Taking of Evidence in International Arbitration, which most DIFC tribunals adopt by reference. This means each side typically presents its own expert, and the tribunal is left to weigh two competing valuations — unless proactive case management narrows the gap between them.
Common Valuation Issues in UAE Construction and Infrastructure Claims:
Quantum experts operating in the DIFC and wider UAE market regularly deal with:
• Prolongation and disruption costs on delayed mega-projects, including towers, rail extensions and utility-scale energy assets • Variations and change order valuation, particularly where FIDIC-based contracts (heavily used across the UAE) leave valuation methodology open to dispute • Loss of profit and loss of opportunity claims following termination or suspension • Quantum meruit assessments where a contract has been found void, frustrated, or terminated for repudiation • Insurance-related quantum, especially in Contractors' All Risks and Delay in Start-Up claims tied to construction and energy projects
What Makes Expert Evidence Persuasive Before a DIFC Tribunal:
DIFC tribunals and the DIFC Courts, drawing on common law traditions, are increasingly alert to the "hired gun" problem — experts who unconsciously (or otherwise) tailor their conclusions to the party paying their fees. A credible quantum expert in this jurisdiction should:
• Set out assumptions transparently, distinguishing between instructed assumptions and independent professional judgment • Address the opposing expert's methodology directly, rather than simply restating a preferred position • Be willing to test conclusions against alternative factual scenarios, particularly where liability findings remain undetermined at the time reports are prepared • Comply with the expert declaration requirements found in the IBA Rules and, where adopted, the CIArb Protocol for Party-Appointed Expert Witnesses
Early Engagement Is the Difference Maker:
Increasingly, DIFC tribunals are encouraging early identification of expert issues — agreeing a common list of questions, exchanging factual evidence before reports are prepared, and directing joint expert conferral ahead of individual reports. Parties who engage a quantum expert only once memorials are due typically lose the opportunity to shape these early procedural steps in their favour.
For contractors, developers, financiers and government entities operating across the UAE's construction, infrastructure, energy and rail sectors, selecting a quantum expert with genuine DIFC and DIAC experience — not simply regional familiarity — is essential to ensuring the evidence withstands scrutiny at hearing.
Key Takeaway:
In DIFC arbitration and litigation, the quantum expert is not a formality appended to the legal case; it is frequently the evidence on which the entire quantum outcome turns. Engaging the right expert early, and ensuring their evidence is procedurally robust and methodologically transparent, materially improves the prospects of a favourable and enforceable outcome.
