About the role
As the Senior Contract Administrator, you’ll oversee contract administration, manage variations, monitor commercial performance and ensure contractual requirements are met. You’ll support strong commercial outcomes through effective risk management, accurate reporting and practical commercial advice to the project team.
The role will be based on Sydney Water’s Willoughby Submain project, a major wastewater infrastructure project aimed at increasing the capacity and resilience of the network across Sydney’s Lower North Shore. The project involves delivering approximately 3 kilometres of new underground wastewater pipeline, with most of the work carried out using microtunnelling.
Specific activities will include:
- Lead end-to-end contract administration across upstream and downstream activities, including negotiations, risk assessments, settlements and claims management.
- Oversee the administration of a diverse range of subcontracts, including payment claims, variations, contractual notices and dispute resolution.
- Mitigate commercial and financial risk by ensuring contracts are accurately drafted, compliant and strategically negotiated.
- Proactively resolve contract issues, manage conflicting requirements and provide clear, timely reporting to senior management.
- Monitor project costs, commitments and commercial performance, identifying potential risks and opportunities for improvement.
- Manage variations, extensions of time and contractual claims, ensuring appropriate supporting documentation and records are maintained.
- Work closely with the project team, subcontractors and client representatives to resolve commercial and contractual matters.
- Support the preparation of monthly commercial reports, cost forecasts and project financial reporting.
- Ensure contractual obligations, project records and commercial processes are maintained in accordance with project and organisational requirements.
Your skills and experience
- Bachelor’s degree in Quantity Surveying, Construction Management, Civil Engineering, or related field.
- 7+ years’ experience in pre-contracts and commercial management on major infrastructure projects; Sydney Water experience highly regarded.
