Why LCG

Subsurface investigation, built on trust.

Multidisciplinary team of registered surveyors, engineers and utility locators. One team, end-to-end delivery, project-grade outputs.

01

Registered Expertise

ISNSW registered surveyors, engineers, urban planners and utility locators. Not a single-service shop. One team from brief to final report.

02

Right Method, Right Site

Ground-penetrating radar for concrete and complex terrain. Electromagnetic locating for cables and pipes. Matched to your site, never one-size-fits-all.

03

Engineer-Ready Reports

Documented, verified deliverables. CAD-compatible outputs. Detailed scan reports, not just marks on the ground for the next crew to interpret.

Every underground service, one team.

Comprehensive subsurface detection across every utility type. Marked, mapped and reported before any excavation.
