The Role

As a
Contracts Administrator
, you will play a vital role in ensuring the commercial success of our water and wastewater projects. You'll manage contracts with precision, ensuring obligations are met, risks are addressed and variations or claims are handled effectively. Working closely with the Commercial & Contracts Manager, Project Managers, subcontractors, and BDM's, you'll provide essential support that keeps projects compliant, profitable and on track.

This role suits a commercially minded professional who thrives in a fast-paced environment. You'll bring strong attention to detail, organisational skills and the ability to balance competing priorities while building trusted stakeholder relationships. In return, you'll gain exposure to significant infrastructure projects and the opportunity to grow within a collaborative, high-performing Commercial team.

Key responsibilities include, but aren't limited to:

• Administer head contracts and subcontracts, ensuring compliance with key dates, deliverables and obligations while maintaining clear communication with project teams.
• Draft, review and manage subcontractor agreements, aligning them with head contract terms and ensuring obligations are accurately flowed down.
• Identify and prepare variation claims, extensions of time and delay costs in accordance with contract requirements, ensuring risks are mitigated and entitlements preserved.
• Maintain robust documentation and registers, including correspondence logs, claims registers and contract deliverables trackers, ensuring audit-ready traceability.
• Support subcontractor tendering, negotiation and award processes, monitoring performance to ensure compliance with insurance, safety, and quality requirements.
• Assist in the preparation of monthly project reports, cost-to-complete forecasts and cash flow projections, providing commercial insights to support decision-making.
• Contribute to early risk identification by escalating potential disputes or contractual issues to the Commercial & Contracts Manager and supporting proactive mitigation strategies.
