Shanahan Civil is a family-owned and operated civil earthworks company based in Goldsborough near Cairns, Far North Queensland. Founded by Josh and Naomi Shanahan, we are driven by a relentless commitment to delivering the highest quality standards on every project we undertake.

With backgrounds in construction, engineering, 3D modelling, and machine operation, we established Shanahan Civil to bridge the gap between advanced digital design and flawless real-world execution. Our complete in-house capability — spanning 3D site capture, precision modelling, and machine-controlled earthworks — allows us to eliminate traditional project silos and deliver superior accuracy, efficiency, and reliability.

At the heart of our operation is advanced Trimble Earthworks 3D machine control technology, integrated across our modern fleet. This precision-focused approach enables us to consistently achieve tight tolerances, reduce rework, minimise material waste, and complete projects ahead of schedule while maintaining uncompromising quality.

As a family business, we take personal pride in every project. Whether it’s a residential building pad, commercial bulk earthworks, deep excavation or a carpark with complex geometry, we treat each site with the same care and attention to detail as if it were our own.

Precision you can build on.
