When the contract is tested, evidence decides. Senior commercial, claims and dispute advisory for Australian construction — partner-led, evidence-built, prepared to withstand scrutiny.
The practice
Billion-dollar projects don't fail politely. When entitlement is contested, the winning position is built from the contract, the records, and the experience to argue them to the best commercial outcome. Sumit Consulting exists for exactly that work — senior advisory without the overheads or dilution of larger consultancies, led hands-on at senior level.

01 — What we do
From the first tender review to the final determination — every discipline serves the same end: entitlement protected, positions provable.
Senior commercial advisory and contract management — embedded or external — from pre-contract risk review and procurement strategy through to final account, focused on risk, entitlement, and outcomes.
Preparation, assessment, and defence of contractual claims for time and money, grounded in contract mechanisms, contemporaneous records, and defensible entitlement strategy.
Proactive dispute avoidance and resolution support, including negotiation strategy, forensic record analysis, and preparation for adjudication or formal proceedings where required.
Quantum analysis for arbitration, litigation, and complex disputes — party-side support and independent expert reports, prepared to tribunal and court standards.
Commercially focused delay and disruption analysis linking programme impacts to contractual entitlement, supported by specialist planning expertise where required.
Expert witness services and strategic Security of Payment support, including early payment claim and schedule preparation, adjudication applications, and responses.
02 — The method
Scattered records become a single, defensible position — built to withstand whoever reads it next.
