Mechanical Engineering Strategies

For Coal Wash Plant Reliability and Maintenance

Coal Handling and Preparation Plants (CHPPs) form the backbone of Australia’s coal production network — from the Bowen Basin to the Hunter Valley and the Central West. Yet these plants face relentless mechanical and environmental challenges. Every tonne of coal that passes through generates impact, vibration, slurry, and corrosion — all of which degrade mechanical systems and shorten asset life.

At Hamilton By Design, we specialise in helping operators and contractors transition from reactive maintenance to precision-based, data-driven engineering. Through advanced 3D scanning, mechanical design, finite element analysis (FEA), and practical shutdown planning, our goal is simple: design for reliability, maintain for efficiency, and execute for safety.

CHPP mechanical reliability | Hamilton By Design

1. Designing for Reliability

Most unplanned failures in a coal wash plant can be traced back to early design decisions. Poor geometry in chutes, undersized bearings, or inadequate access provisions make routine maintenance more difficult and increase safety risks. The starting point for reliability is a mechanical design that aligns with plant realities:

Ease of access and installation: Every component should be replaceable without cutting, grinding, or excessive crane time.
Defined load paths: Support structures, monorails, and lifting lugs should be rated and certified under AS 4991 Lifting Devices.
Material selection: Use quenched and tempered steel (e.g. Bisalloy) in high-impact zones and lighter wear materials (rubber, ceramic, UHMWPE) where abrasion dominates.
Design compliance: Reference AS 1418 (Cranes, Hoists & Winches) and AS 4100 (Steel Structures) for any interfaces involving lifts, frames, or platforms.
Constructability focus: Consider how each component will be installed, aligned, and torqued during a shutdown, not just how it performs in theory.

A well-designed plant doesn’t just last longer — it’s easier and safer to maintain, which means less time offline and more consistent throughput.

2. The Role of Regular Inspections in Corrosive CHPP Environments

Coal and water are a dangerous combination for steel. Over time, the interaction of moisture, oxygen, and fine coal particles creates a mildly acidic environment, especially in sumps, under conveyors, and around wet chutes or launders. This acidity accelerates corrosion, particularly on untreated or aging steelwork.

Regular inspection is therefore the most powerful preventive tool in CHPP maintenance. It’s not just about finding rust — it’s about identifying where corrosion will occur next.

Effective inspection programs include:

Daily operator checks: Visual walk-arounds to spot early staining, pitting, or flaking coatings.
Weekly mechanical reviews: Checking bolt tension, bearing temperature, and visible steel condition.
Quarterly or shutdown inspections: Ultrasonic thickness testing on chutes, hoppers, and frames to track material loss.
Annual 3D scanning campaigns: Comparing LiDAR models taken months apart to measure deformation and quantify corrosion over time.

These inspections reveal weak points long before failure occurs. When combined with a structured maintenance schedule, they prevent unplanned shutdowns, reduce emergency welding, and extend the life of key structural assets.

3. Data-Driven Maintenance and Condition Monitoring

Gone are the days when experienced operators relied purely on “listening to the plant.” Today, modern CHPPs use real-time data acquisition to monitor vibration, temperature, load, and alignment. But human senses still play a vital role — a trained ear or touch can detect imbalance and overheating that instruments might miss.

The best maintenance strategies blend both approaches:

Motor load tracking detects overloading on conveyors, screens, and pumps.
Vibration analysis identifies bearing fatigue, misalignment, or imbalance before catastrophic failure.
Infrared thermography highlights hot bearings and electrical faults invisible to the naked eye.
Ultrasonic testing and thickness gauging provide a measurable indication of steel degradation, especially in wet, acidic areas.
3D LiDAR scanning visualises wear zones and helps engineers create accurate “digital twins” for comparison across time.

These digital twins allow maintenance planners to pinpoint deformation, misalignment, or structural movement down to millimetre precision — transforming the CHPP into a living mechanical system that can be analysed and optimised continuously.

4. Scan-to-Model Precision Engineering

Every coal wash plant evolves over time — upgrades, patch welds, retrofits, and pipe reroutes all cause the as-built layout to drift from the original drawings. That’s where 3D scanning becomes essential.

High-definition LiDAR captures millions of data points, recreating the plant in precise digital form. Engineers can then model new chutes, screen decks, or pump bases directly within the scanned environment to:

Validate fit-up tolerances before fabrication.
Confirm lifting paths and crane clearances.
Verify bolt access and maintenance envelopes.
Overlay FEA results on the as-built geometry for fatigue and stress validation.

This scan-to-model approach eliminates costly surprises during shutdowns. By resolving interferences virtually, projects achieve faster installation times, fewer clashes, and minimal rework.

5. Finite Element Analysis (FEA) for Structural Assurance

CHPP components endure cyclic loads, vibration, and impact — all prime conditions for fatigue failure. Finite Element Analysis (FEA) allows engineers to simulate these conditions in a virtual environment.

Typical boundary conditions include:

Static loads: Dead weight of chutes, liners, and supporting frames.
Dynamic forces: Screen exciters, slurry impact, and conveyor discharge trajectories.
Support stiffness: Bolted bases or gusseted connections with realistic compliance.
Modal analysis: Identifying natural frequencies and avoiding resonance near operating speeds.

By evaluating stress concentrations, weld toe fatigue, and deflection limits, engineers can predict life expectancy and optimise reinforcement. In practice, FEA-based validation reduces over-engineering while ensuring safety compliance — particularly under Australian Standards.

6. Smart Wear Management and Material Selection

Wear is inevitable in coal preparation plants, but premature wear is preventable. The correct wear lining can double or even triple component lifespan. Material choice depends on particle size, density, velocity, and impact energy — all of which dictate how energy is transferred during collisions.

Typical solutions include:

Quenched & tempered steel (e.g. Bisalloy) for high-impact loading zones such as chute lips or transfer points.
Rubber or polyurethane linings for abrasion under low to moderate impact.
Ceramic tiles in high-velocity or high-temperature zones for excellent hardness and longevity.
UHMWPE (ultra-high-molecular-weight polyethylene) for low-friction, non-stick surfaces.

An integrated wear-management plan combines condition monitoring, liner mapping, and service-life tracking to forecast when replacement should occur — preventing failures rather than reacting to them.

7. Pumping and Slurry Transfer Systems

Slurry transport is one of the most maintenance-intensive systems in a wash plant. Pipelines must balance velocity high enough to avoid settling with low enough wear to preserve liners and reduce energy use.

Key mechanical considerations include:

Critical velocity: Maintaining 1.2–1.5× the settling velocity for the slurry type.
Pipe material: Rubber-lined steel for coarse solids; HDPE for fines or corrosive conditions.
Head loss and pump selection: Balancing static and friction losses while ensuring sufficient Net Positive Suction Head (NPSH).
Elbow design: Long-radius bends reduce turbulence and localised wear.
Instrumentation: Pressure taps, flow sensors, and vibration alarms for predictive monitoring.

With proper design and inspection, slurry systems can run reliably for years, with predictable replacement schedules instead of costly mid-campaign failures.

8. Conveyor Transfer Design and Particle Trajectory

A common source of dust, spillage, and liner wear in CHPPs lies in poorly designed transfer points. Understanding particle trajectory — the path and velocity at which material leaves one conveyor and enters a chute — is fundamental to mechanical efficiency.

Well-engineered transfers:

Match the material stream to the receiving chute curvature.
Minimise drop height and impact angle.
Incorporate impact beds, skirting systems, and wear liners.
Control dust through controlled flow and enclosure design.

Using trajectory modelling and 3D scanning, engineers can predict exactly how material will behave — improving throughput, reducing clean-up, and extending the life of belts and liners.

9. Shutdown Planning and Pre-Fabrication QA

Shutdowns are high-pressure events where planning equals performance. A successful mechanical shutdown doesn’t begin on day one — it starts months earlier with design validation and fabrication quality checks.

Before any new chute or structure reaches site, engineers should confirm:

Lifting compliance: Lugs rated to AS 4991, with centre of gravity marked and rigging plans approved.
Fit-up accuracy: Scan-to-model verification to ensure tolerance within ±2–5 mm.
Fastener integrity: Correct bolt grade, torque accessibility, and alignment.
Coating and liner QA: Correct material, cure time, and installation sequence.
Trial assembly: Ground trial or partial fit to validate alignment before shipment.
Documentation: ITPs, weld maps, NDT reports, coating certificates, and as-built models delivered before mobilisation.

The result is confidence — everything fits, everything lifts safely, and everything performs as expected.

10. Integrating Safety, Engineering, and Operations

Mechanical reliability is inseparable from safety. Failures of worn chutes, cracked supports, or seized bearings not only halt production but endanger lives.

Integrating engineering design, maintenance, and operations into a shared feedback loop is the hallmark of a mature CHPP. Operators provide condition data, engineers refine designs based on site feedback, and planners adjust maintenance intervals based on performance data.

This closed-loop approach, often referred to as Digital Engineering in Maintenance, underpins the next generation of CHPP optimisation — where 3D models, scanning data, and maintenance histories all live within a single digital environment.

11. The ROI of Engineering-Led Maintenance

Transitioning from reactive to predictive maintenance produces measurable returns.
Typical improvements seen across similar Australian wash plants include:

Category	Typical Improvement	Example Outcome
Unplanned downtime	20–40% reduction	Fewer emergency shutdowns
Liner lifespan	30–50% increase	Longer change-out intervals
Safety incidents	25% reduction	Fewer reactive tasks in confined spaces
Fabrication rework	60–80% reduction	Fit-first-time installations
Shutdown duration	10–20% shorter	More production hours per year

These gains demonstrate why combining mechanical engineering, digital scanning, and structured maintenance is not a cost — it’s an investment.

12. Confidence Through Engineering Discipline

Coal wash plants will always be demanding environments. Yet through smarter design, continuous inspection, and disciplined maintenance, reliability and safety can be engineered into every tonne of coal produced.

At Hamilton By Design, we combine SolidWorks modelling, FEA validation, LiDAR scanning, and mechanical design expertise to help site teams achieve practical, data-driven reliability. Whether it’s a structural upgrade, chute redesign, or complete plant model, our process ensures each project is safe to lift, easy to install, and built to last.

Mechanical Engineering Sydney

Why Local Expertise Beats Offshore Design

When “Cheap” Design Becomes Expensive

It’s a familiar story across Sydney’s construction and manufacturing sectors.
A project manager outsources design work overseas to save money, only to find that the drawings don’t match Australian standards, the steelwork doesn’t fit, and fabrication costs double.

In a world where engineering software is accessible anywhere, the temptation to go offshore can be strong — but experience shows that local expertise consistently delivers better results, faster approvals, and fewer headaches.

At Hamilton By Design, we combine 25+ years of hands-on trade and design experience to deliver mechanical solutions that work on paper and in the field.
From Sydney to Newcastle and the Central Coast, we understand the standards, materials, and site realities that offshore design simply can’t replicate.

Why Local Mechanical Engineering Matters

Sydney’s industrial landscape — from Parramatta fabrication shops to Eastern Suburbs infrastructure projects — operates under strict Australian Standards, local codes, and safety expectations.
Designing within this environment demands more than CAD skills; it requires context, compliance, and communication.

Offshore engineers often miss critical local details such as:

Material availability and substitution restrictions.
Australian welding standards (AS 1554, AS 4100).
Local fabrication tolerances and workshop capabilities.
Site access limitations for installation and cranage.
Council or engineering certification processes unique to NSW.

When those factors are overlooked, small errors become costly problems — rework, delayed approvals, or even non-compliant builds.

Local mechanical engineers, however, design with those realities in mind from day one.

Understanding Australian Standards and Compliance

Compliance is non-negotiable in Australia.
Mechanical systems, structural frames, and lifting equipment must conform to AS/NZS standards to ensure safety and durability.

At Hamilton By Design, our design workflows are aligned to:

AS 4100 – Steel Structures
AS 3990 – Mechanical Equipment Design
AS 4991 – Lifting Devices
AS 1657 – Fixed Platforms, Walkways & Stairs
AS 1210 – Pressure Vessels
AS 4024 – Machine Safety

These codes aren’t optional — and many offshore designers aren’t even aware of them.
The result? Drawings that look fine digitally but fail certification or require complete redesign once they reach Australian soil.

When you engage a Sydney-based mechanical engineer, compliance is built into the design process — not patched in later.

Fabrication Drawings That Fabricators Actually Use

Ask any fabricator what they want from a designer, and the answer is simple: clear drawings that work in the shop.
Hamilton By Design delivers fabrication packages made for real-world conditions, with:

Logical part numbering and weld symbols.
Assembly sequencing that matches how fabricators work.
Accurate bills of materials with locally available sections and plate thicknesses.
Clearly dimensioned hole patterns, folded parts, and weld prep details.

Because we’ve spent years on the workshop floor and behind the CNC machine, we know what fabricators need — and what slows them down.

Our fabrication drawings are reviewed by tradespeople before release, ensuring that what’s designed digitally can be built confidently in Sydney, Newcastle, or the Central Coast.

mechanical engineering Sydney, fabrication drawings, local engineer, 3D design, Central Coast, Newcastle, SolidWorks,

Local Knowledge of Materials and Supply Chains

Sydney’s fabrication ecosystem depends on specific steel grades, fasteners, and surface treatments available through regional suppliers.
Offshore designers often specify materials that can’t be sourced locally or that don’t meet AS/NZS equivalents.

By contrast, Hamilton By Design draws on local supply-chain knowledge to:

Select materials from Australian distributors (Bluescope, Atlas Steels, Bisalloy).
Specify coatings and finishes suited to Sydney’s coastal conditions.
Design for local machining and bending capacities.

That local insight reduces procurement delays and eliminates unnecessary cost from imported materials or non-standard sizes.

Site Access and Installation Reality

Anyone who has worked on-site in Sydney knows the physical challenges — tight access, heritage constraints, sloped terrain, or congested industrial zones.
An offshore designer working from a photograph can’t account for those details.

Our process starts with 3D scanning and LiDAR modelling, capturing every measurement accurately before design begins.
This ensures all new platforms, pipe runs, and mechanical assemblies fit perfectly within existing structures.

We also design with installation in mind — bolt-up sequences, crane reach, and modularisation to minimise time on site.
That’s the difference between designing for construction and merely designing on a computer.

Faster Approvals and Smoother Communication

When you work with a Sydney-based engineer, you can pick up the phone, visit the workshop, or meet on site.
That proximity streamlines:

Council and certifier reviews.
Fabrication drawing mark-ups and RFIs.
On-site design adjustments and re-scanning if required.

Offshore communication delays — time zones, translation issues, and conflicting units — disappear.
A local team speaks the same technical language, understands your timeline, and values your reputation.

That responsiveness can be the difference between a smooth build and a month-long delay.

Designed for the Sydney Environment

Sydney’s climate and infrastructure pose unique engineering challenges — from salt-laden coastal air to temperature swings, rainfall, and urban vibration.
Mechanical systems designed for another country’s conditions often fail prematurely or require re-engineering.

Hamilton By Design accounts for:

Corrosion protection suitable for coastal and industrial zones.
Load cases reflecting Australian seismic and wind conditions.
Access and safety standards enforced under Work Health and Safety Regulation 2017 (NSW).

That local awareness keeps your equipment compliant, safe, and reliable for the long term.

Seamless Integration with 3D Design and Scanning

Hamilton By Design uses SolidWorks 3D design, LiDAR scanning, and point-cloud modelling to create true-to-life digital models.
This approach ensures every bracket, chute, or mechanical component fits within the existing plant or structure before fabrication begins.

For builders and contractors in Sydney, Newcastle, and the Central Coast, that means:

Accurate visualisation for client approval.
Zero rework at installation.
Precise fabrication drawings linked directly to 3D models.

We can even produce e-drawings and interactive 3D viewers, allowing site teams to measure and explore designs directly from their phones or tablets.

Supporting Sydney’s Builders, Fabricators, and Plant Managers

Our clients range from small fabrication workshops in Parramatta and Penrith to large construction and maintenance contractors servicing industrial plants across Newcastle and the Central Coast.

We support them with:

Mechanical design and reverse engineering.
Fabrication drawings and BOMs ready for workshop production.
3D scanning and as-built modelling for brownfield sites.
FEA validation for load-bearing components and lifting devices.
On-site consultation and measurement verification.

Whether you’re installing a new platform, modifying a chute, or planning a plant upgrade, local expertise saves time, reduces rework, and ensures compliance from concept to commissioning.

Real-World Experience You Can Trust

Hamilton By Design is more than an office-based design service.
Our principal engineer has worked as a qualified fitter-machinist and CNC tradesman, managed fabrication projects, and spent years designing with SolidWorks and FEA for mining and industrial applications.

That blend of hands-on experience and digital precision means our designs consider not just how things look — but how they’re built, lifted, bolted, and maintained.
It’s practical engineering, grounded in real industry knowledge.

Local Relationships, Long-Term Results

By working with a Sydney-based engineering partner, you’re not just buying drawings — you’re building a relationship.
We collaborate with local certifiers, builders, and suppliers who know the industry and share your standards for quality and reliability.

That network helps projects move faster through approval, fabrication, and commissioning — because everyone’s aligned on the same outcome: a safe, compliant, and cost-effective result.

Case Study: Central Coast Pumping Station Upgrade

A recent client on the Central Coast required a structural and mechanical redesign of a pump access platform within a tight footprint.
The existing layout was poorly documented, and an offshore contractor’s drawings failed to align with on-site geometry.

Hamilton By Design performed a 3D scan, built a SolidWorks model, and produced compliant fabrication drawings that matched the real-world structure precisely.
The new design was installed without modification, saving the contractor both time and budget — and earning praise from the certifier for documentation quality.

The Real Cost of Offshore Design

At first glance, offshore design can appear cheaper — but only on paper.
Once you add rework, redesign, freight delays, and certification issues, costs escalate quickly.
The true value lies in getting it right the first time.

Factor	Offshore Design	Local Sydney Engineer
Knowledge of Australian Standards	Limited	Comprehensive
Fabrication Compatibility	Often requires rework	Designed for local workshops
Site Visits & Measurements	None	Included
Approval Delays	Common	Fast turnaround
Communication	Slow, time zone barriers	Direct and responsive
Total Cost	Unpredictable	Transparent and accountable

In short: cheap drawings can lead to expensive outcomes.

Sydney Expertise with Regional Reach

While based in Sydney, Hamilton By Design services clients across Newcastle, the Central Coast, and Western Sydney — regions where local understanding matters.
We’re familiar with the area’s industrial environments, from coastal fabrication yards to inland manufacturing plants.

This regional reach means clients receive consistent quality whether their project is in Chatswood, Gosford, or Beresfield — backed by the same hands-on engineering standards.

Partner with a Local Engineer Who Knows the Ground

Mechanical engineering isn’t just about software — it’s about understanding how things fit together in the real world.
Sydney’s construction and industrial projects demand more than drawings; they require compliance, precision, and accountability.

At Hamilton By Design, we bring together trade experience, SolidWorks expertise, and 3D scanning technology to deliver mechanical solutions that work from concept to commissioning.

From Point Cloud to Precision: How Digital Twins Simplify Plant Upgrades in Brisbane and Beyond

Turning Brownfield Complexity into Digital Clarity

Across Brisbane, the Bowen Basin, and Queensland’s industrial heartlands, countless processing plants are running on legacy drawings that no longer match reality.
Walk into any CHPP, manufacturing line, or materials-handling facility, and you’ll find it — pipework that’s been rerouted, platforms extended, and modifications made during years of operation.

When engineers attempt an upgrade based on outdated layouts, these mismatches become costly.
That’s why forward-thinking operators are now using digital twin technology to bridge the gap between what’s on paper and what exists on site.

At Hamilton By Design, we transform 3D laser-scanned point clouds into fully detailed SolidWorks models, enabling Brisbane-based engineers, EPCM firms, and asset owners to design with precision and build with confidence.

What Is a Digital Twin — and Why Brisbane Industry Needs It

A digital twin is an exact digital replica of your physical plant.
Created from LiDAR-based 3D scanning, it captures every bolt, beam, and bracket with sub-millimetre accuracy.
This isn’t just a visual model — it’s a live data set that supports retrofit engineering, mechanical design, and long-term asset management.

For Brisbane’s industrial facilities — from Port of Brisbane terminals to mining equipment workshops in Rocklea — this technology transforms guesswork into evidence-based design.
Whether planning a CHPP upgrade or a new conveyor line, engineers can now simulate, test, and validate in the digital environment before fabrication begins.

Step 1: Capturing the Real World – 3D Laser Scanning

The process starts in the field.
Hamilton By Design’s team uses high-precision FARO-style laser scanners to collect millions of data points per second.
Each scan produces a point cloud, a three-dimensional snapshot that records the true geometry of every structure, pipe, and surface.

Multiple scans are stitched together to create a single, unified model — the foundation of your plant’s digital twin.
This data can be captured safely, without scaffolding or shutdowns, making it ideal for Brisbane’s operational manufacturing and processing facilities.

Step 2: Turning Data into Design – SolidWorks Modelling

Once scanning is complete, the real engineering begins.
Hamilton By Design imports the point cloud into SolidWorks, where the physical plant is reconstructed digitally.

This is where Brisbane’s mechanical design expertise meets advanced 3D technology.
Each new chute, frame, or platform is designed directly inside the scanned environment — no guesswork, no assumption.
Every bolt hole and clearance is modelled against the actual geometry captured on site.

This integration between SolidWorks 3D models and point-cloud data allows us to deliver designs that fit first time, every time.

Step 3: Engineering Verification and Clash Detection

A digital twin is more than a model — it’s a verification tool.
Using SolidWorks, we perform full clash detection and clearance validation before fabrication begins.
We can simulate installation, maintenance access, and lifting sequences — identifying conflicts before steel is ordered.

That’s the difference between reactive problem solving during a shutdown and proactive engineering months beforehand.

For EPCM and GRES-type firms managing complex brownfield projects around Brisbane, Gladstone, and the Surat Basin, this workflow delivers tangible time and cost savings.

Real-World Example: Brisbane CHPP Upgrade

A Brisbane-based EPCM client engaged Hamilton By Design to support a coal wash plant upgrade north of Moranbah.
The task: replace an existing transfer chute and realign conveyor supports during a tight 72-hour outage.

We laser-scanned the structure before shutdown, then developed a digital twin in SolidWorks to model the new design.
During digital fit-up, several interferences with legacy supports were discovered — issues that would have caused major rework if identified on site.

Because the conflicts were solved digitally, fabrication proceeded smoothly, and installation was completed 12 hours ahead of schedule.
The result: no rework, reduced risk, and a satisfied client.

Why Brisbane Engineers Are Moving to Point-Cloud Modelling

Brisbane’s engineering community is known for practical innovation — finding smarter ways to build, maintain, and optimise industrial assets.
Point-cloud modelling aligns perfectly with that mindset, offering measurable benefits:

Accuracy: Every model reflects the as-built plant, not outdated drawings.
Speed: Laser scanning captures an entire facility in hours, not weeks.
Safety: Measurements are taken from the ground — no working at height or confined space entry.
Efficiency: Design errors are caught before fabrication.
Communication: Digital models and e-drawings make collaboration simple across offices in Brisbane, Mackay, and Newcastle.

For firms managing assets across Queensland’s mining corridor, this is a game-changer.

Digital Twins Simplify Retrofits and Debottlenecking

Every brownfield project is unique — but the challenges are universal: tight space, limited data, and even tighter schedules.
Digital twins eliminate those unknowns by giving engineers a real-world reference for every modification.

Common applications include:

Chute and bin upgrades – precisely fitted to existing support frames.
Conveyor transfer redesigns – perfect belt alignment verified digitally.
Pipework and pump tie-ins – no misalignment or last-minute field welding.
Platform and access upgrades – confirmed compliance and clearance.
Dust suppression systems – integrated seamlessly into crowded plant layouts.

When every millimetre counts, digital precision prevents costly on-site improvisation.

How Digital Twins Improve EPCM Collaboration

For EPCM firms based in Brisbane, coordination across multiple contractors and disciplines is a daily reality.
Digital twins provide a shared model that unites design, fabrication, and construction teams under one digital source of truth.

Through e-drawings and 3D viewers, teams can review the model from any location — measuring, marking up, and validating in real time.
This reduces ambiguity and speeds up decision-making during the design and procurement phases.

It’s digital engineering that feels tangible — clear, collaborative, and built for real-world application.

The ROI of Digital Twin Workflows

The business case is simple: the cost of scanning is negligible compared to the cost of rework or downtime.
Across Brisbane’s industrial sector, plant shutdowns can cost $20,000–$50,000 per hour in lost production.
When digital validation prevents even half a day of delay, the return on investment exceeds 500%.

Project Stage	Without Scanning	With Digital Twin
Site Measurement	Manual & high risk	Fast LiDAR capture
Fit-Up Accuracy	Variable	Verified digitally
Shutdown Delays	Frequent	Minimized
Safety Risk	High	Reduced
ROI	Uncertain	Consistent, measurable

For project managers, that’s not an upgrade — it’s an insurance policy.

Brisbane’s Emerging Digital Engineering Hub

Brisbane is fast becoming a centre for digital engineering in mining, infrastructure, and manufacturing.
Local EPCM firms, fabrication shops, and maintenance contractors are integrating point-cloud modelling into their workflows to stay competitive.

On-site scanning services throughout Queensland
SolidWorks-based mechanical design and FEA analysis
Fabrication drawings, e-drawings, and as-built verification

Our team bridges the field and the design office, providing a practical link between hands-on engineering and advanced digital modelling.

Beyond the Project: Asset Management Through Digital Twins

A digital twin doesn’t expire when the upgrade ends.
Once created, it becomes a powerful asset management tool.

Plant owners across Brisbane and Central Queensland are now using these models to:

Track modifications and maintain accurate as-built records.
Plan future expansions without new site surveys.
Integrate performance and maintenance data directly into the model.
Improve HSE planning through digital visualisation of confined spaces and access zones.

This is the foundation of Industry 4.0 — where real-world assets and their digital counterparts operate as one continuous system.

From Point Cloud to Precision: How Digital Twins Simplify Plant Upgrades

The Problem with Guesswork in Brownfield Design

Upgrading or modifying an existing processing plant is never straightforward.
Whether it’s a coal handling preparation plant (CHPP) in the Bowen Basin, a water treatment facility on the Central Coast, or a manufacturing plant in Sydney, every brownfield project faces the same challenge: nothing is ever exactly where the drawings say it should be.

Over time, structures settle, pipe runs are rerouted, and maintenance crews make unrecorded modifications. When a new chute, tank, or platform is designed on old drawings, these discrepancies become expensive mistakes.

That’s why industry leaders are embracing digital twin technology — accurate, data-driven 3D replicas that bring the real world into the design space.
At Hamilton By Design, we turn laser-scanned point clouds into SolidWorks 3D models, giving engineers the confidence that every new component will fit — before fabrication begins.

What Is a Digital Twin?

A digital twin is more than a 3D model — it’s a living digital replica of a physical asset or environment. Built from LiDAR-based 3D scans, the twin mirrors the as-built geometry of the plant, allowing engineers to test, model, and validate upgrades in a risk-free digital space.

When used in mechanical and structural design, the digital twin becomes a single source of truth — integrating point cloud data, SolidWorks 3D design, and FEA validation into one seamless workflow.

For brownfield engineering, this approach eliminates uncertainty, reduces design iteration time, and provides a data-rich foundation for future asset management.

Step 1: Capturing Reality – 3D Scanning and Point Clouds

The process starts in the field. Using a FARO Focus or equivalent LiDAR scanner, Hamilton By Design captures millions of data points across the plant in just minutes.

Each scan produces a high-resolution “point cloud” — a dense 3D map of the environment that captures every surface, structure, and detail with millimetre-level accuracy.
Multiple scans are then registered together, creating a unified 3D dataset of the entire facility.

This digital foundation eliminates the need for risky manual measurements, allowing site teams to capture geometry safely from the ground — even in areas that are difficult to access during shutdowns.

Step 2: From Scan to SolidWorks – Building Accurate 3D Models

Once the point cloud is complete, the next stage is reverse engineering.
Our team imports the scan data into SolidWorks, using it as the base reference for modelling equipment, structures, and assemblies.

Every new design element — from chutes, platforms, and handrails to entire processing modules — is created directly within the scanned environment.
This means the new model fits exactly within the existing plant, ensuring alignment, clearance, and accessibility are verified digitally long before site installation.

By combining mechanical trade knowledge with advanced CAD integration, Hamilton By Design bridges the gap between the site and the screen — delivering models that work in the field, not just in theory.

Step 3: Verifying Fit and Function

With the digital twin in place, the design team can perform full interference checks and clash detection.
SolidWorks allows engineers to simulate installation sequences, check for obstructions, and validate maintenance access zones.

This pre-emptive digital validation reduces the risk of on-site surprises — no more cutting steel or shifting structures during shutdown because a bolt hole was 20 mm off.

The result is faster installation, fewer delays, and safer working conditions.

Step 4: Visualisation and Collaboration

Another major advantage of digital twins is communication.
Gone are the days of handing over static 2D drawings and expecting everyone to visualise how the upgrade will fit.

Using e-drawings and interactive 3D viewers, Hamilton By Design delivers models that clients, fabricators, and site teams can explore in real time.
Project managers can rotate, zoom, and measure within the model — improving collaboration between engineering, procurement, and construction teams.

For EPCM firms and asset owners, this level of transparency builds trust and eliminates ambiguity across the project lifecycle.

Digital Twins in Action: A Bowen Basin Retrofit Case Study

A CHPP client in the Bowen Basin recently engaged Hamilton By Design to support a debottlenecking project.
The goal: replace a series of ageing transfer chutes and install new dust-suppression ducting during a single 72-hour outage.

Traditional methods would have required weeks of manual site measurement and still left uncertainty about alignment.
Instead, the plant was 3D-scanned ahead of time, and the resulting point cloud was used to model the new chute assemblies directly within SolidWorks.

During digital fit-up, the team identified several interferences with an adjacent walkway and pipe rack — issues that would have caused at least two days of rework during installation.
By resolving these digitally, fabrication could proceed with confidence.

The outcome:

Zero rework on site
All chutes installed within schedule
Measurable reduction in shutdown duration and cost

That’s the value of precision modelling — turning what used to be reactive problem-solving into proactive engineering.

Retrofit and Debottlenecking Made Simple

In existing facilities, every upgrade is a retrofit — and retrofits mean unknowns.
Digital twins remove those unknowns, simplifying retrofit engineering by aligning new design intent with existing geometry.

Typical applications include:

Chute and bin replacements – modelled within existing support frames
Conveyor transfer upgrades – validated for accurate belt alignment
Pump and pipework retrofits – ensuring perfect tie-ins
Platform and access redesigns – verified for clearance and compliance
Dust control and ducting systems – fitted seamlessly into congested layouts

Whether it’s a single component or a full process module, designing within a digital twin eliminates guesswork and ensures efficient integration.

Why EPCM Firms Choose Hamilton By Design

EPCM firms and asset owners often juggle multiple contractors, tight deadlines, and high-stakes budgets.
Partnering with Hamilton By Design provides a trusted mechanical engineering partner that understands both the digital tools and the practical realities of plant work.

Our advantages include:

25 + years’ mechanical and design experience
Trade background in fitting and machining for practical engineering judgement
Proficiency in SolidWorks and FEA since 2011
Field scanning and modelling capability using advanced LiDAR systems
Focus on brownfield projects in mining, manufacturing, and construction

When we model your plant, we’re not guessing — we’re designing with data.

The ROI of Getting It Right the First Time

It’s easy to underestimate the cost of poor fit-up.
A single misaligned flange or interference during installation can cascade into lost production, emergency rework, and safety risks.

By using a digital twin workflow, the cost of scanning and modelling (typically < 1 % of project cost) can save days of unplanned downtime worth hundreds of thousands of dollars.

Activity	Traditional Approach	With Digital Twin
Measurement & Verification	Manual site survey	LiDAR scan (1 day)
Design Basis	Old GA drawings	Accurate as-built geometry
Fit-Up Risk	High – frequent clashes	Minimal – verified digitally
Rework Cost	5–10 % of fabrication	< 1 % (if any)
Installation Time	Extended shutdown	On schedule or early
ROI	Variable	Consistently > 500 %

Digital accuracy isn’t a luxury — it’s an investment in certainty.

Beyond Design: The Future of Asset Management

The benefits of digital twins extend far beyond project completion.
Once the scan and 3D model are established, they form the basis for ongoing asset management.

Plant owners can track modifications, plan future expansions, and link operational data (like vibration or flow metrics) directly to the 3D model.
As a result, maintenance, safety, and capital planning teams share a unified, visual platform for decision-making.

It’s a step toward true Industry 4.0 — where physical and digital systems work hand in hand to optimise plant performance.

Sydney’s Engineering Advantage

While Hamilton By Design supports projects nationwide, our Sydney base gives EPCM firms and asset owners in Chatswood, Parramatta, and the Eastern Suburbs direct access to digital engineering expertise.

For construction projects, fabrication workshops, and manufacturing facilities across the city, point-cloud modelling provides a competitive advantage in accuracy and presentation.
Our digital twins are particularly valuable for council approvals, BIM coordination, and client visualisation — ensuring every stakeholder understands the proposed upgrade in full 3D.

Collaborative Design, Real-World Precision

At Hamilton By Design, we believe the best engineering happens when designers, fabricators, and site crews speak the same language.
That’s why our deliverables go beyond drawings — we provide fully navigable 3D models, e-drawings, and markup views that make collaboration simple.

Every stakeholder — from EPCM engineers to on-site trades — can see exactly how the upgrade will install, reducing ambiguity and improving project flow.

From Point Cloud to Precision

Every successful plant upgrade begins with accurate information.
If you’re still relying on legacy drawings or manual measurements, you’re gambling with time, cost, and safety.

By transforming point clouds into digital twins, Hamilton By Design delivers:

Perfect-fit upgrades every time
Reduced rework and shorter shutdowns
Seamless coordination across design, fabrication, and construction
A digital asset that supports future operations

Get your plant upgrade modelled in 3D before you order steel.
It’s faster, safer, and smarter — and it starts with a scan.
