From 3D Scanning to Mechanical Engineering – Designing Mining Plant Upgrades That Fit
How point clouds, SolidWorks modelling and engineering judgement help reduce fabrication uncertainty in mining operations.
Why Accurate Geometry Matters in Mining Engineering
Mining and mineral processing plants operate in demanding environments where equipment must remain reliable despite continual wear, maintenance and modification.
Over time, conveyors are relocated, transfer chutes replaced, pipework modified and new mechanical equipment installed.
Unfortunately, the original engineering drawings do not always reflect these changes.
For mechanical engineers, this creates a familiar challenge.
How do you design new equipment to fit an existing mining plant when the installed geometry is uncertain?
One solution is to combine 3D LiDAR scanning with mechanical engineering and CAD modelling.
Hamilton By Design provides these integrated services to support mining equipment modifications, brownfield plant upgrades and shutdown engineering projects across Australia.
Rather than treating 3D scanning as an isolated measurement exercise, the captured geometry becomes part of the engineering design process.

3D Scanning for Engineering in Mining – Equipment, Chutes, Conveyors and Plant Upgrades
1. The Difference Between Measuring Equipment and Engineering a Solution
3D LiDAR scanning captures the visible geometry of existing equipment, structures and surrounding plant infrastructure.
The resulting point cloud provides a spatial reference for the installed arrangement.
However, a point cloud does not automatically determine whether a proposed modification is mechanically suitable.
Engineering decisions must also consider:
Mechanical loads and operating conditions.
Material flow and equipment performance.
Wear and fatigue.
Structural and mechanical interfaces.
Maintenance access.
Installation clearances.
Fabrication tolerances.
Applicable Australian Standards.
For example, scanning may establish the position of an existing conveyor discharge pulley.
However, engineering assessment is still required to determine the appropriate transfer chute geometry, material trajectory, wear protection and support arrangement.
Measurement establishes what exists. Engineering determines what should be designed.
2. Using Point Clouds in SolidWorks Mechanical Design
Once site scanning is complete, the captured information can be registered into a coordinated point cloud.
This dataset can be used as a reference for developing 3D CAD models.
For mining equipment modifications, the objective is generally not to model every component in the processing plant.
Instead, the engineering model should contain sufficient relevant geometry to support the proposed modification.
This may include:
Existing conveyor positions.
Mechanical equipment connection points.
Chute flanges and discharge interfaces.
Structural support locations.
Pipework and equipment obstructions.
Access platforms and maintenance clearances.
Hamilton By Design uses SolidWorks and other CAD tools to develop mechanical equipment models and engineering documentation.
The resulting models can support equipment arrangements, dimensional reviews, fabrication planning and design coordination.
3. Mechanical Engineering for Brownfield Mining Plants
Brownfield engineering involves modifying or upgrading existing facilities rather than designing an entirely new plant.
This creates additional engineering challenges because new equipment must operate within established physical constraints.
Consider the installation of a replacement pump skid.
The new equipment may need to connect to existing pipework, foundations, electrical services and maintenance access areas.
A 3D scan can help establish the available space and existing connection geometry.
The engineering model can then be used to investigate:
Equipment positioning.
Pipework connections.
Baseplate and support arrangements.
Maintenance access.
Installation requirements.
Potential interference with surrounding equipment.
This approach is equally relevant to conveyor modifications, transfer chute replacement and mechanical equipment upgrades.
4. Engineering Verification Before Fabrication
One of the most valuable uses of 3D scanning is the ability to review proposed equipment within the existing plant arrangement before fabrication begins.
For example, a replacement conveyor transfer chute may appear suitable when viewed as an isolated CAD model.
However, once positioned within the existing-condition model, potential problems may become apparent.
These could include interference with nearby structural steel, inadequate maintenance clearance or differences between assumed and actual connection positions.
Engineering review can identify these issues earlier.
Where required, additional assessments may include:
Static mechanical calculations.
Finite Element Analysis (FEA).
Fatigue assessment.
Equipment support verification.
Material flow assessment.
Fabrication tolerance review.
Not every project requires advanced analysis. The appropriate level of engineering verification depends on the equipment, operating conditions and project risks.
Importantly, 3D scanning does not replace precision measurement of critical interfaces where tighter tolerances are required.
5. From Engineering Models to Fabrication Drawings
A completed 3D model can provide the basis for developing manufacturing and installation documentation.
Depending on the project, this may include:
General arrangement drawings.
Mechanical assembly drawings.
Fabrication details.
Component and material schedules.
Connection details.
Installation arrangements.
Engineering review documentation.
The objective is to provide fabricators and installation teams with information that reflects both the proposed design and the existing site conditions.
This is particularly important for mining shutdown projects where installation time is limited.
6. Reducing Shutdown Risk Through Better Engineering Information
Mining shutdowns frequently involve equipment that has been fabricated before the existing installation is removed.
If the new equipment does not fit, the installation team may need to undertake additional cutting, welding or modification work.
These activities can increase project costs and extend installation time.
Combining 3D scanning with mechanical engineering can help reduce this risk.
The typical process is:
Scan → Register → Model → Design → Verify → Detail → Fabricate → Install
Each stage provides an opportunity to identify uncertainties before they affect the next activity.
Although no measurement or design process can eliminate every installation risk, better existing-condition information supports more informed engineering decisions.
7. Engineering Applications Across Mining Operations
The combination of 3D scanning and mechanical engineering can support a broad range of mining activities.
Coal Handling and Preparation Plants
Transfer chute replacement, conveyor modifications, equipment access improvements and processing plant upgrades.
Copper and Gold Processing Facilities
Mechanical equipment replacement, pipework modifications, pump skids and brownfield plant upgrades.
Mineral Sands Processing
Conveyor transfer points, equipment interfaces, processing plant modifications and mechanical design.
Mobile Mining Equipment
Dimensional assessment, reverse engineering, wear component development and equipment modification planning.
Bulk Material Handling Facilities
Conveyor arrangements, transfer stations, hoppers, chute modifications and equipment installation planning.
Across these applications, the common engineering challenge is integrating new or modified equipment with existing infrastructure.
8. Why Engineering Judgement Remains Essential
Digital technology has changed how engineers capture and interpret existing plant conditions.
However, the availability of detailed point clouds and sophisticated CAD software does not remove the need for engineering judgement.
A point cloud can establish equipment geometry.
A CAD model can represent a proposed design.
Engineering analysis can investigate mechanical performance.
But the engineer must still determine whether the information is sufficient, the assumptions are reasonable and the proposed solution is appropriate for the operating environment.
At Hamilton By Design, the objective is to combine digital measurement with practical mechanical engineering.
The value is not simply in creating a digital model. It is in using that model to support better engineering decisions.
