Machine Control Modelling
3D grading and design models built for GPS machine-control earthworks.
Overview
Machine control modelling translates civil grading and site design drawings into 3D surface models compatible with GPS-guided earthmoving equipment. CanMaple Consultant builds machine control models for earthworks contractors and site developers across Edmonton and Alberta, reducing the survey staking and manual layout work that traditional grading otherwise requires.
GPS-guided grading equipment has become standard on most mid-to-large Alberta earthworks projects, but the equipment is only as accurate as the model it's following. A model built directly from the civil design, checked against the design drawings before it reaches the contractor, reduces the risk of a grading error that's expensive to correct once material has already been moved.
Who This Service Is For
- Earthworks and grading contractors using GPS-guided equipment.
- Developers and site owners whose civil design needs to be handed off in a machine-control-ready format.
- General contractors coordinating grading subcontractors on a site with tight tolerances.
Common Challenges We Address
- A civil grading design exists on paper but the contractor's equipment needs a 3D model to work from.
- Survey staking for a large or complex site is slow and expensive compared to machine-guided grading.
- A model needs to be checked against the design drawings before it's used for construction to avoid costly grading errors.
- Different equipment or software on site needs the model delivered in a specific file format.
Scope of Service
- 3D surface and grading model development, built from civil design drawings.
- GPS machine-control file preparation, formatted for the contractor's equipment and software.
- Model quality assurance against the design drawings, checking that the model accurately reflects the intended grading.
- Contractor coordination to confirm file formats, tolerances and delivery timing.
Typical Deliverables
- 3D surface models built to the design grading.
- Machine-control files formatted for the contractor's GPS equipment.
- QA documentation confirming the model matches the design drawings.
Project Types
Land development
Machine control models for subdivision and site grading on development projects.
Site works
Models for individual site grading and drainage construction.
Roadworks
Machine control models supporting road and access grading.
How the Engagement Works
Design confirmation
We confirm the finalized civil grading design the model will be built from.
Model construction
The 3D surface model is built to reflect the design grading and drainage intent.
Format and tolerance confirmation
We confirm the file format and tolerances the contractor's equipment requires.
QA and delivery
The model is checked against the design drawings before delivery to the contractor.
Alberta & Edmonton Considerations
Machine control modelling relies on accurate site survey and design information — Alberta's varied terrain and clay-heavy soils in the Edmonton region make precise grading models particularly valuable for avoiding drainage problems that are costly to correct after construction.
Alberta's earthworks season is also compressed by winter conditions — ground freezing typically limits productive grading work to a shorter window than in milder climates. Machine control accuracy helps contractors move faster within that window, since less time is spent on manual staking and rework compared to conventional survey-based grading.
Working With Your Project Team
Machine control models are built directly from CanMaple's own civil grading designs where CanMaple has provided the design, or from another consultant's issued drawings where the civil design comes from elsewhere — either way, models are checked against the design intent before being released for construction use.

Frequently Asked Questions
What file formats do you deliver machine control models in?
Model formats are confirmed with the contractor as part of scoping, matched to the GPS equipment and software being used on site.
Can you build a model from a design that wasn't produced by CanMaple?
Yes — machine control models can be built from another consultant's issued civil drawings, provided the design information is complete enough to model accurately.
How is the model checked for accuracy?
Models are quality-checked against the source design drawings before delivery, confirming grades and drainage intent are accurately represented.
Does machine control modelling replace survey staking entirely?
It significantly reduces the need for traditional staking on GPS-equipped sites, though some survey control points are still typically required to set up the equipment.
What do you need from me to start a machine control model?
Finalized civil grading design drawings, and confirmation of the equipment/software format the model needs to be delivered in.
Can you update a model if the design changes mid-project?
Yes — revised models can be produced as design changes occur, keeping the contractor's equipment working from current information rather than an outdated grading plan.
Do you work directly with the earthworks contractor, or only the owner?
Both — CanMaple coordinates directly with the contractor on file formats, tolerances and delivery timing, while keeping the owner or design lead informed of progress.
Does machine control modelling work for small sites as well as large developments?
Yes — models are scoped to the site regardless of size; a small site simply requires a smaller, faster modelling scope than a large development.
