Estimate differently. See the projects you price come to life under the same roof.

Prebuilt is seeking an experienced Estimator to join our growing commercial team at our 9,000m² manufacturing facility in Kilsyth.

This is an opportunity to work across a diverse pipeline of permanent modular construction projects throughout Victoria and New South Wales, collaborating closely with our design, projects, construction and leadership teams.

Unlike traditional construction, our integrated approach means you'll have direct visibility across design, estimating, manufacturing and delivery – and you'll be able to see the projects you price being built right here in our facility.

About Prebuilt

For more than 20 years, Prebuilt has been a leader in permanent modular construction, delivering innovative residential and commercial buildings across Victoria and New South Wales.

We combine design, manufacturing and construction to create high-quality, sustainable buildings while continuing to challenge traditional methods of construction.

With continued growth across VIC and NSW, we're looking for an experienced Estimator who wants to play an important role in the next stage of our growth.

The Prospect

As an Estimator at Prebuilt, you'll be responsible for developing accurate and competitive cost estimates across a range of construction projects.

Working closely with our Bid, Design and Project teams, you'll assess project requirements, develop detailed pricing and provide the commercial insight required to support successful project outcomes.

Your responsibilities will include:

- Review and interpret architectural and construction drawings, specifications and tender documentation




- Prepare detailed cost estimates covering labour, materials, equipment and subcontractor packages
- Complete quantity take-offs and develop accurate project cost plans
- Obtain, review and negotiate supplier and subcontractor quotations
- Work closely with our Bid Manager to develop competitive and commercially sound tender submissions
- Collaborate with designers, project managers, engineers and construction teams to validate scope and pricing
- Identify project risks, exclusions, opportunities and potential cost impacts
- Attend site inspections and tender briefings where required
- Prepare and present estimates, budgets and recommendations to management
- Assist with tender clarifications and contract negotiations
- Maintain and improve historical cost data and estimating information
- Support project teams with cost-related queries and handover following successful tenders
- Monitor market conditions, construction methodologies and material costs to continually improve estimating accuracy

About You

We're looking for someone who understands construction, enjoys getting into the detail and can balance accuracy, commercial thinking and deadlines.

Ideally, you'll bring:

- Previous estimating experience within commercial construction or a related sector
- Strong ability to read and interpret architectural, structural and construction documentation




- Experience preparing detailed cost estimates and quantity take-offs
- Positive knowledge of construction materials, trades, subcontractor packages and methodologies
- Strong commercial awareness and ability to identify project risks and opportunities
- Experience obtaining and assessing supplier and subcontractor quotations

- Excellent attention to detail and organisational skills
- Confidence working across multiple tenders and competing deadlines
- Strong communication and stakeholder management skills
- Proficiency with estimating software and Microsoft Office
- Relevant construction, quantity surveying or estimating qualifications would be highly regarded

Experience within modular, prefabricated, commercial building, education or government projects would be advantageous, but isn't essential.

Why Join Prebuilt?

At Prebuilt, you'll be part of an established construction business that’s continuing to grow and evolve.

You'll enjoy:

- A permanent, full-time opportunity with long-term career potential
- A diverse pipeline of commercial and residential projects
- Exposure to projects across both Victoria and New South Wales
- The opportunity to work closely with experienced construction, design and project professionals
- Direct visibility of the manufacturing and construction process
- A collaborative environment where your commercial input is valued
- The opportunity to contribute to an innovative and growing area of the construction industry

If you're an experienced Estimator looking for a role where you can have genuine input, work across compelling projects and be part of an innovative construction business, we'd love to hear from you.
