Approved design surface
Start from a controlled terrain model with clear revision and engineering authority.
Advanced Engineering · Precision Earthworks
Connect the approved terrain model to field execution and verified surfaces.
Model-to-Machine Construction is Big Three Engineering’s precision-earthworks method: digital terrain models, machine guidance, cut/fill intelligence and survey verification working as one controlled workflow.
Quick answer
What changes in model-to-machine earthworks?
The workflow moves from approved digital terrain models to machine guidance, continuous position awareness and verified as-built surfaces.
- Digital terrain models
- RTK GNSS and machine guidance
- 3D machine control
- Automated cut/fill analysis
- Drone, LiDAR and survey verification
Big Three innovation model
Make the engineering model executable in the field.
Precision earthworks supports roads, platforms, mine infrastructure, industrial sites, developments, embankments and drainage. The goal is to reduce interpretation gaps between design information and the machine shaping the ground.
Nexus connects the approved design surface with field production data, compares planned and actual surfaces and preserves digital as-built evidence. Intelligent compaction and automated production tracking extend the same model-to-field workflow.
Connected capabilities
How this fits into the Big Three delivery model.
Each capability strengthens engineering decisions, construction execution, evidence and lifecycle value across the project lifecycle.
Machine guidance
Provide operators with digital position, grade and design context using suitable GNSS and control systems.
Cut/fill intelligence
Use model-based quantities and production planning to optimise material movement.
Continuous verification
Use survey, drone or LiDAR evidence to verify surfaces and identify variance earlier.
Compaction intelligence
Connect compaction data to treatment, coverage and verification records.
Digital as-built
Preserve the verified final surface as part of the construction evidence and handover record.

Frequently asked questions
Practical answers about how Big Three Engineering connects digital engineering with physical delivery.
What is model-to-machine construction?
It is a workflow where approved digital design surfaces are used by machine-guidance or machine-control systems and then verified using survey or reality-capture data.
Where can it be used?
Applications include roads, platforms, industrial sites, mine infrastructure, developments, bulk earthworks, embankments and drainage.
How does survey control strengthen model-to-machine delivery?
Survey control establishes the coordinate framework, calibration and independent verification that connect the approved design surface to accurate field execution and as-built evidence.
What evidence should be produced?
Useful evidence can include approved surfaces, control and calibration records, production data, verification surveys, drone or LiDAR comparisons and digital as-built surfaces.
