We are seeking an experienced Quantity Surveyor / Contracts Administrator to join our team delivering works for BHP on the Ministers North project.

Supporting the Commercial Manager, you will play a key role in preparing progress claims, assessing completed works and providing accurate commercial and progress reporting.

This is a practical, site-based role requiring close collaboration with the onsite Construction Manager. You will need to understand what is happening on the ground, verify progress and translate site information into transparent, well-supported commercial submissions.

We are looking for someone with a minimum of five years’ relevant experience who can work independently, manage competing priorities and consistently meet deadlines.

The position operates on a 5/2, 4/3 roster.

- Assist the Commercial Manager in resolving discrepancies and progressing claim assessments.

Progress and commercial reporting

- Assess construction progress against the scope of works, programme and relevant payment milestones.

- Prepare clear, accurate progress reports for the Commercial Manager.
