TrenchingCabling and ReticulationAll In-House
We manage underground electrical works from the ground up, using our own fleet of excavators, trenchers, and specialised machinery. This allows us to control delivery, maintain quality and reduce delays—whether working on a local project or a remote regional site.
From early-stage trenching and pit installation to power distribution and final testing, our experienced team handles every stage of the underground process with safety and efficiency front of mind.
Supporting Civil and Remote Projects Across FNQ
Our underground and civil works are designed to meet local authority specifications, developer needs and future growth requirements. With extensive experience working in remote and regional communities, we’re equipped to deliver infrastructure in hard-to-access areas where careful planning and self-sufficiency are essential.
We collaborate with developers, councils, engineers and other contractors to deliver fully integrated underground services that support both new developments and upgrades to existing networks.
