- Analyse schedules of rates, BOQ line items, and unit rate breakdowns to establish and quantify entitlement accurately.
- Compile contemporaneous records — site diaries, daily labour records, plant logs, and photographs — to substantiate cause-and-effect narratives within each claim.
- Maintain claim registers and variation logs across the project portfolio, tracking status, submitted value, assessed value, and outstanding amounts.
- Cross-reference Procore, ERP, or project accounting systems against contractual cost codes to verify cost-to-date figures underpinning each claim.
- Perform rate analysis, measured-mile studies, and labour productivity assessments to quantify loss of productivity claims.
- Submit completed claims to the client in accordance with contractual timeframes and notice requirements.
- Serve as the primary liaison between the company and the client on all claim-related matters, including delays, variations discrepancies, disputes, and recovery negotiations.
- Prepare and issue contractual notices, RFIs, and formal correspondence within prescribed timeframes to protect the company’s contractual position.
- Track client responses and assessments; identify gaps between submitted and assessed values and prepare rebuttal or supplementary submissions as required.
- Manage dispute resolution processes including adjudication submissions, Scott Schedule responses, and expert witness coordination where required.
- Perform financial modelling and scenario analysis to evaluate claim exposures, settlement ranges, and negotiation positions.
- Interrogate and reconcile schedules of rates, plant hire rates, material quotes, and subcontract pricing to validate rate-based claims.
- Ensure adherence to commercial, legal, risk management and corporate governance policies and procedures.
- Strong knowledge of the ‘back to back’ concept in contract formation, how to identify and implement ‘flow-down/up’ provisions into a contract hierarchy and then manage that dynamic during operation of the contract.
- Advanced understanding of the linkages between operational, financial, legal and commercial issues.
- Coaching, mentoring and delivering commercial & contract management training and best practice to staff
