UAE claims succeed on four disciplines: notices served in time, a programme-based delay analysis, contemporaneous records linking cause to effect, and quantum built event by event — never globally.
Every distressed UAE project produces the same three claims: more money for changed work, more time for delay, and the costs of being kept on site. The entitlement usually exists. What separates recovery from write-off is preparation discipline — starting long before anyone calls it a dispute.
Variations: instructed and constructive
Instructed variations follow the machinery: written instruction, valuation under the contract, done. The fights live in constructive variations — scope pushed through shop-drawing comments, "clarifications" that add work, design development driven past the contract baseline. UAE tribunals recognise them, but the burden is the contractor's: prove the work was extra (against a defined baseline), required (paper the direction), and not priced. A live scope-baseline register, maintained from day one, is worth more than any pleading written later.
EOT: time first, money second
The extension-of-time claim relieves delay damages and anchors prolongation. Its three load-bearing elements:
- Notice — served within the contractual window (below).
- Delay analysis — programme-based, method appropriate to the records, honest about contractor culpability. Analyses that blend causes get pulled apart by tribunal-appointed experts.
- Causation records — the daily diary of what actually held the works.
Concurrent delay has no codified UAE answer: outcomes follow the particular conditions and the tribunal's approach — commonly time granted, money scrutinised. Negotiate concurrency wording at signing; separate the causes in the analysis; win the point in the records.
Notices: the 28-day guillotine
Condition-precedent notice clauses are routinely enforced by tribunals sitting in the UAE. Good-faith and prevention arguments exist for the worst cases; nobody should plan around them. The discipline is operational: a notice matrix built at contract award, site staff trained on triggers, and a standing rule — when in doubt, notify. A protective notice costs a paragraph; a missed one can cost the claim.
Prolongation and the cost record
Time-related costs — staff, site establishment, equipment, financing — recovered for compensable delay periods. The claims that pay are the ones whose cost systems were set up to answer the question: costs coded to events and periods, actual (not tender-rate) records, head-office overheads approached with a method the tribunal can test. Lump-sum spreadsheets assembled at the end are where prolongation claims go to die.
Global claims: the shortcut that isn't
Rolling every overrun into one composite claim signals that causation can't be proven — and tribunals treat it accordingly. Event-by-event causation with discrete quantum costs more to prepare and multiples less to lose. If the records won't support disaggregation, that is a settlement-strategy fact worth knowing before the arbitration, not during it.
Where claims get decided
Engineer's determinations first (preserve everything — the Engineer's independence is often compromised by the particular conditions), negotiation and settlement windows next, then DIAC or ICC arbitration — or the court-expert process if the contract chose the courts. The forum shapes how records and analyses are weighed, which is why the disputes clause deserves front-end attention.
