Our client is a well-established civil infrastructure contractor with a long track record of delivering complex, high-value projects across Queensland and the wider Australian market. Known for technical capability and disciplined delivery, they have built a reputation as a trusted partner to government agencies, asset owners and major private-sector clients.

Operating across transport, water and broader civil sectors, the business delivers work under a range of procurement models, from traditional construct-only contracts through to design and construct, early contractor involvement and collaborative delivery frameworks. This breadth gives them a strong, diversified position in a market that continues to see sustained investment.

With South East Queensland entering one of the most significant periods of infrastructure spending in its history, the business is in a phase of strategic growth. Investment in their pre-contract and estimating capability is central to that plan, creating an opportunity for a senior estimator to step into a role with real influence over which projects are won and how they are priced.

WORKING ENVIRONMENT & PROJECTS

Based in the Brisbane office, you will join a capable and collaborative estimating and tendering team that works closely with design, planning, commercial and operations leaders. The culture is commercially sharp but supportive, with an open-door leadership style and a strong emphasis on accuracy, accountability and teamwork.

The tender pipeline spans a broad mix of civil infrastructure, including roads and motorways, bridges and structures, rail, water and wastewater, and major earthworks and site development packages. Opportunities range from mid-sized projects through to large, multi-year schemes, giving you exposure to some of the most technically demanding work in the state.

You will be involved from early bid strategy and go/no-go decisions through to final submission, client negotiations and handover to the delivery team.



This end-to-end involvement means your work directly shapes the commercial foundations of projects that will define the region for years to come.
