Who we are

RSGx is a trusted provider of mechanical and electrical construction and engineering solutions, with a strong focus on supporting the global energy transition. We deliver end-to-end services across the entire project lifecycle—from front-end engineering and design to construction, completions, commissioning, and start-up.

The opportunity

We are seeking an experienced Contracts Administrator with a strong claims focus to join our commercial team. Reporting directly to the Financial Controller, this role is central to the preparation, submission, and management of contractual claims across our Project Services Portfolio.

You will take ownership of the end-to-end claims process; from reading the contract and identifying entitlement' through to preparing fully substantiated claim documents, submitting to the client, and managing all follow-up correspondence until resolution. You will be the primary point of contact for clients on all claim-related matters, including delays, discrepancies, and disputed amounts.

Candidates with an accounting background or strong numerical aptitude will be well placed to quantify disruption, delay, and variations in a manner that withstands scrutiny.

Key responsibilities

• Read and interpret contract documents (AS 4000, AS 4902, GC21, NEC3/4, FIDIC) to identify entitlement, notice obligations, and claim mechanisms.
• Prepare detailed claim sheets for each claimable event, including variations, extensions of time (EOT), disruption, and prolongation costs, with full supporting cost build-ups.
• 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, discrepancies, disputed assessments, 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.
• Prepare executive claim status reports and presentation materials for the Financial Controller, senior management, and legal teams.
• 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.
• Support the Financial Controller with monthly cost reporting, forecast-to-complete analysis, and commercial risk reviews.
• Mentor junior claims staff and support knowledge transfer in rates analysis, claim documentation, and commercial strategy.

About you

• Demonstrated expertise reading and administering schedule-of-rates and lump sum contracts under AS 4000, GC21, NEC3/4, or FIDIC.
• Proven ability to prepare end-to-end claim documents — from entitlement identification through to formal submission and client negotiation.
• Strong written communication skills; capable of drafting structured, evidence-based claim documents and client correspondence.
• Advanced Microsoft Excel proficiency for cost build-ups, financial modelling, and claim tracking.
• Experience with Procore, Aconex, SAP, or equivalent cost control platforms preferred but not required.
• An accounting qualification or demonstrated background in financial analysis or project cost accounting is highly desirable.
• A collaborative approach with the ability to work closely with the Financial Controller, project managers, and legal/commercial counsel.
