Oasis Building Group is seeking an experienced and passionate Senior Estimator to join our growing Ballarat team. We are a locally owned custom building company specialising in new homes, renovations and extensions, and medium-density residential developments throughout Ballarat and surrounding regions. With a diverse pipeline of projects, no two jobs are the same, making this an ideal opportunity for an experienced estimator who enjoys variety, problem-solving and being involved across the full project lifecycle.

About the role

As our Senior Estimator, you will take ownership of the end-to-end estimating process, working across sales, pre-construction, production and procurement. This is a senior, hands-on role where you’ll work closely with our in-house drafting, design, sales, construction and estimating teams to take projects from initial concept through to construction. We’re looking for someone who is technically strong, commercially minded and confident working across a diverse range of projects. As a client-facing role, you’ll also be a strong communicator who enjoys building relationships with clients, trades, suppliers and the wider Oasis team.

Your responsibilities will include:

- Manage end-to-end estimating across sales, production and procurement for current homes, renovations and medium-density developments.

- Prepare accurate project estimates, take-offs, budgets and cost plans from architectural, engineering and consultant documentation.

- Coordinate trade and supplier pricing, scopes and procurement, maintaining strong relationships with our subcontractor and supplier network.

- Work collaboratively with our in-house sales, drafting and construction teams, identifying cost efficiencies, project risks and buildability considerations.

- Experience using Constructor estimating software is highly regarded, along with confidence adopting new technology, systems and AI-assisted tools.

- Provide estimating support throughout the client journey, including pricing discussions and variations,



while utilising our estimating software and emerging AI systems to improve efficiency.

Experience across multiple residential construciton types will be highly regarded. Versatility is important to us, as our projects are custom by nature, and no two jobs are the same.

Why Join Oasis?

At Oasis, we pride ourselves on maintaining a positive, collaborative working environment where people are encouraged to contribute ideas, develop professionally and take genuine ownership of their role.

You won't be estimating the same standard home repeatedly. You'll work across a varied pipeline of custom residential projects, renovations and developments alongside experienced in-house drafting, design, sales, estimating and construction teams.

You'll also have exposure to the future of residential construction through our sister company, Dune Building Technologies, and its work in 3D concrete printing and emerging construction technology.

For the right person, this creates opportunities for ongoing career and professional development, exposure to innovative construction methods, and the chance to grow alongside both businesses.

What We Offer

- A senior role with genuine ownership and responsibility

- Diverse and interesting residential projects

- End-to-end involvement rather than a narrowly defined estimating function

- Support from an established internal team and evolving AI-enabled systems

- A collaborative and positive Ballarat-based working environment

- Direct interaction with clients, trades, suppliers and project stakeholders

- Professional development and opportunities for career progression

- Exposure to innovative construction and 3D concrete printing through Dune Building Technologies

- The opportunity to join a locally owned business with an exciting pipeline of future projects

If you're an experienced residential estimator looking for greater variety, responsibility and the opportunity to work across both traditional and emerging construction, we'd love to hear from you.

Please contact this number 0421 237 *** to apply for the job, and when calling please leave your name, number and a team member will be in contact with you.
