Meet the Founder

Rob Bishop

Founder | Estimator | Procurement Specialist

After more than 20 years working across Estimating, Procurement, Operations and Construction, I founded Dusani with one clear purpose—to work with Builders and provide Construction Clarity while delivering High Quality Projects.

Throughout my career, I saw talented Builders losing time, margin and opportunities, not because they lacked capability, but because they lacked the right people. Estimates became rushed, Procurement was reactive, and Business systems struggled to keep pace with growth.

Dusani was built to change that.



Today, I partner with Residential Builders across Australia, providing Estimating, Procurement and Construction Support Services that improve accuracy, streamline operations and create confidence throughout every stage of the building process.

As a Construction Professional with hands-on Residential Construction experience, I understand how homes are built—not just how they're priced. That practical knowledge allows me to deliver Construction focused solutions that work in the real world.

Whether it's providing additional Estimating capacity, creating Estimating databases, managing Procurement or helping improve internal systems, my goal is always the same:

To help builders deliver better projects with greater confidence, stronger margins and less risk.
