Heavy industrial facilities rarely remain unchanged. Smelters are continually upgraded to improve production, replace ageing equipment, meet environmental regulations and increase operational efficiency. Over decades of operation, countless modifications are made, many of which are only partially documented or never recorded at all. As a result, engineering teams are often forced to work with outdated drawings, incomplete documentation or no reliable three-dimensional CAD model of the facility.

Hamilton By Design provides Smelter Scan to CAD Services in Newcastle NSW, transforming high-accuracy terrestrial laser scan data into engineering-grade CAD models that accurately represent existing plant conditions. These models provide a trusted foundation for brownfield engineering projects, shutdown planning, equipment replacements, structural modifications and future asset management.

Whether your project involves replacing conveyors, upgrading process equipment, modifying structural steel, rerouting pipework or expanding a processing facility, having an accurate digital model of the existing plant dramatically reduces project risk while improving engineering confidence.

Why Existing Smelter Drawings Cannot Always Be Trusted

Many smelters operating throughout the Newcastle and Hunter Region have been in service for decades. During this time they have experienced numerous shutdowns, maintenance campaigns and capital improvement projects.

Typical undocumented changes include:

Additional platforms and access walkways
Modified conveyor systems
Pipe rerouting
Structural steel alterations
Equipment replacements
Cable tray additions
Temporary modifications becoming permanent
New services installed around existing infrastructure

While individual projects may have produced updated drawings, these revisions are not always consolidated into a complete plant model. Over time, engineering documentation becomes fragmented, making it increasingly difficult to determine the true “as-built” condition of the facility.

This creates significant challenges whenever new engineering work is required.

The Cost of Working from Outdated Information

When engineering teams lack an accurate three-dimensional representation of the plant, projects become more complex than necessary.

Common issues include:

Unexpected clashes during installation
Fabrication errors
Incorrect field measurements
Delayed shutdowns
Increased site rework
Additional crane time
More site welding and modifications
Higher project costs
Safety risks associated with unforeseen obstacles

Every incorrect assumption increases project risk.

Accurate Scan to CAD services eliminate much of this uncertainty by providing engineers with an engineering-grade digital representation of the existing facility before design work begins.

What is Scan to CAD?

Scan to CAD is the process of converting terrestrial laser scan data into intelligent engineering models.

Rather than relying solely on old drawings or manual measurements, millions of highly accurate laser measurements are captured throughout the facility to create a complete three-dimensional point cloud.

Experienced engineers then interpret this data to develop accurate CAD models representing existing equipment, structures and plant layouts.

The result is an engineering model that reflects the current state of the facility—not how it looked twenty years ago.

Our Scan to CAD Workflow

Hamilton By Design follows a structured engineering workflow designed specifically for complex industrial facilities.

1. High-Accuracy Laser Scanning

Using professional terrestrial laser scanners, millions of survey-grade measurements are captured throughout the plant.

Typical assets include:

Furnace buildings
Material handling systems
Pipework
Tanks
Chutes
Hoppers
Structural steel
Platforms
Conveyors
Cable trays
Mechanical equipment
Access structures

Large facilities can be captured with complete overlap to ensure comprehensive coverage and minimal shadowing.

2. Point Cloud Registration

Individual scans are registered into one accurate coordinate system.

This creates a unified digital representation of the entire facility while maintaining engineering-grade accuracy suitable for detailed design work.

3. Engineering Interpretation

Unlike automated modelling software, engineering interpretation identifies:

Structural members
Mechanical equipment
Process pipework
Equipment interfaces
Critical connection points
Existing plant constraints

Engineering judgement ensures the model reflects functional plant assets rather than simply reproducing raw geometry.

4. CAD Model Development

Point cloud data is converted into engineering CAD models suitable for design and documentation.

Depending on project requirements, deliverables may include:

Mechanical equipment
Structural steel
Pipework
Access platforms
Stairs
Handrails
Tanks
Ducting
Buildings
Foundations

Models can be produced to the required Level of Detail (LOD) to support conceptual studies, detailed engineering or fabrication.

5. Verification

Critical dimensions are checked against the registered point cloud before project completion.

Verification commonly includes:

Flange locations
Bolt centres
Equipment centres
Structural interfaces
Pipe elevations
Nozzle positions

This verification process gives engineering teams greater confidence that the CAD model accurately reflects existing site conditions.

Typical Smelter Applications

Scan to CAD services support a wide range of engineering activities, including:

Brownfield Plant Modifications

Existing infrastructure is accurately modelled before new equipment is designed.

This significantly reduces installation conflicts.

Shutdown Planning

Shutdown durations are often measured in hours rather than days.

Accurate CAD models enable:

Off-site fabrication
Installation planning
Lift studies
Construction sequencing
Clash reviews

Better planning helps minimise production downtime.

Conveyor Upgrades

Conveyor replacements frequently require precise integration with existing structures.

Scan to CAD provides engineers with accurate structural interfaces before fabrication begins.

Structural Modifications

Existing platforms, access systems and support structures can be accurately modelled before alterations are designed.

This improves fabrication accuracy while reducing field modifications.

Equipment Replacement

Replacement pumps, tanks, vessels, ductwork and process equipment can be designed to fit existing plant geometry before arriving on site.

Engineering Software Compatible Deliverables

Hamilton By Design can supply deliverables compatible with many common engineering platforms, including:

SOLIDWORKS
Autodesk Inventor
AutoCAD
Autodesk Plant 3D
Autodesk Revit
Navisworks
STEP
SAT
DWG
DXF
IFC
E57
RCP
LAS

This flexibility allows engineering teams to continue working within their preferred software environment.

Benefits of Accurate Scan to CAD Models

Investing in accurate engineering models provides measurable project benefits:

Reduced site measurements
Improved design accuracy
Lower fabrication risk
Fewer installation clashes
Reduced shutdown duration
Better project planning
Faster engineering workflows
Improved asset documentation
Enhanced maintenance planning
Long-term digital asset management

For facilities undertaking ongoing brownfield improvements, a reliable CAD model becomes a valuable engineering asset that continues delivering value long after the initial scanning project is complete.

Supporting Newcastle’s Heavy Industry

Newcastle has long been recognised as one of Australia’s major industrial centres, supporting steel manufacturing, mineral processing, bulk materials handling, port infrastructure and heavy engineering. Many of these facilities have evolved through decades of expansion, leaving engineering teams with incomplete or outdated documentation.

Hamilton By Design specialises in engineering-led Scan to CAD services that bridge this gap. By combining high-accuracy terrestrial laser scanning with mechanical engineering expertise, we produce practical CAD models that support real-world engineering decisions.

Whether your project involves a single process area or an entire smelter, our workflow provides engineering teams with accurate digital information they can rely on for design, fabrication and construction.
