Data Preparation & Machine Control Support
Accurate data preparation is essential for translating design intent into real-world construction outcomes. At GMC Surveying, cad data and drawings are transformed into coordinated, construction-ready digital models that integrate seamlessly with GPS machine control systems and on-site workflows.
By aligning design models with ground conditions, control networks, and equipment specifications, GMC helps clients reduce rework, minimise downtime, and deliver precise, efficient construction, from earthworks through every layer to final trim.
Capabilities Overview
+ Digital Terrain Model (DTM) Creation
Clean, accurate surface models of every layer developed from
design plans for use in earthworks and set-out.
+ Design Layer Separation & Feature Coding
Organisation and simplification of design data into machine-readable layers.
+ 3D Model Conversion & Validation
Transformation of civil design files into machine-ready formats compatible with all industry systems.
+ Mass Haul Analysis
Strategic modelling of cut/fill movements to optimise haul distances, reduce fuel use, and support staging decisions.
+ Site Calibration Files
Custom site calibrations aligned with project control points and coordinate systems to ensure field accuracy.
+ Quality Assurance & File Testing
Rigorous validation of all machine control files before deployment to minimise field errors.
+ Take-Off Volumes
Precise material volume calculations from design vs. existing
surface models, through every layer to include earthworks and all pavement volumes.
+ Updates & Version Control
Ongoing support to reflect design changes, field conditions, or construction sequencing adjustments.
By leveraging 3D machine models for every layer, our clients benefit from faster cycle times, tighter tolerances, lower fuel and material waste, and significantly improved project outcomes.
