Accurate earthworks data is critical to keeping bulk excavation and site preparation projects on schedule and within budget. GMC Surveying provides
reliable, high-precision survey support for every stage of earthworks, from initial site establishment to final conformance checks.
Working closely with contractors, engineers, and machine control operators, GMC ensures seamless integration between design intent and on-ground execution. Survey solutions are tailored to maximise productivity, reduce rework, and deliver compliance-ready results.
Precise layout of excavation limits, fill zones, and design levels
for cut/fill guidance.
Regular updates to track earthworks progress against design
and quantify production for contractor claims.
Ongoing verification of excavation depth, slope alignment, and
level tolerances throughout the project.
Final verification of earthworks surfaces to demonstrate
compliance with design specifications and QA documentation.
Accurate measurement of material moved using pre- and
post-earthworks surface models.
Volumetric assessments for material management, stocktake,
and haul planning.
Preparation and delivery of GPS-ready models, site calibrations,
and file formats compatible with Trimble, Topcon, and Leica
systems.
Provision of responsive onsite surveying services to resolve
issues, update designs, and implement changes in real time,
minimising downtime and delays.
From pre-start site assessments to final conformance checks, we provide high-precision data that drives construction efficiency, compliance, and cost control.
