Machine Control & 3D Models

3D construction surfaces and geometry for compatible GPS-guided plant.

Service overview

Machine-control model creation

GRIDSURVEYING AND MAPPING LTD prepares 3D construction models from approved design information for compatible machine-control systems used on dozers, excavators and other earthmoving plant.

Models can cover bulk earthworks, formation, subgrade, finished levels, roads, platforms, excavations, slopes, ponds/basins and other project surfaces defined by the approved design.

Approved design reviewCheck source geometry, revisions, coordinate framework and construction build-ups.
3D model creationBuild the required surfaces, boundaries, breaklines and guidance geometry.
QA & issue controlCheck model geometry, transitions, file structure and design revision before issue.

03

Model creation

Build the required construction surfaces and guidance geometry.

04

Quality assurance

Check levels, coordinates, breaklines, triangles, limits, transitions and model continuity.

05

Export & integration

Questions

Machine Control & 3D Models FAQ

What types of machine-control models can you create?

Typical work includes bulk earthworks, cut/fill, formation, subgrade, finished surfaces, roads, platforms, excavations, ponds/basins, slopes and phased construction surfaces.

What information is needed to create a model?

Original 3D design data is preferred, together with the project coordinate and level framework, current approved revisions and any confirmed build-up depths or construction offsets required to derive lower surfaces.

Can models be updated when the design changes?

Yes. Revised approved geometry can be reviewed, affected model areas rebuilt and a new controlled issue prepared for the confirmed machine-control workflow.

Does machine control remove the need for survey checks?

Project control, machine calibration and independent survey checks remain important, particularly at critical levels, interfaces and before work is covered or handed over.
