Proven Engineering. Real Results. Every project starts with a challenge — tight shutdowns, outdated drawings, structural fatigue, or a need to innovate fast. At Hamilton By Design, we bring practical design engineering, LiDAR scanning, and SolidWorks expertise together to deliver reliable, measurable outcomes for clients across mining, manufacturing, and data-centre infrastructure.
Explore some of our featured case studies below.
CHPP Chute & Launder Replacement – Hunter Valley

3D LiDAR Scan-to-Model Retrofit – Central Coast
Scope: Full as-built capture of process plant and mechanical upgrade integration. Challenge: No reliable drawings existed; site shutdown window limited to 24 hours. Our Approach:
High-accuracy terrestrial LiDAR scanning
Point-cloud registration and SolidWorks conversion
Clash detection and layout optimisation
Deliverables in STEP and DWG formats
Outcome: Delivered verified as-built model within 48 hours, enabling prefabrication of pipe spools with zero site rework.
Scope: Lifting and access frame redesign for production line maintenance. Challenge: Existing frame lacked design documentation and had unknown load paths. Our Approach:
Reverse-engineered frame geometry using scanning
Conducted FEA load analysis to AS 4991 (Lifting Devices)
Every coal wash plant in Australia tells the same story: constant throughput pressure, harsh operating conditions, and the never-ending battle against wear, corrosion, and unplanned downtime. The reality is simple — if you don’t engineer for reliability, you’ll spend your time repairing failure.
At Hamilton By Design, we specialise in mechanical engineering, 3D scanning, and digital modelling for coal handling and preparation plants (CHPPs). Our goal is to help site teams transition from reactive maintenance to a precision, data-driven strategy that keeps production steady and predictable.
Design for Reliability — Not Reaction
Reliability begins with smart mechanical design. Poor geometry, limited access, and undersized components lead to fatigue and repeated downtime. Instead, modern CHPP maintenance programs start by engineering for fit, lift, and life:
Fit: Design components that align with the existing structure — every bolt, flange, and mating face verified digitally before fabrication.
Lift: Incorporate certified lifting points that comply with AS 4991 Lifting Devices, and ensure clear access paths for cranes or chain blocks.
Life: Select wear materials suited to the physics of the process — quenched and tempered steel for impact, rubber or ceramic for abrasion, and UHMWPE for slurry lines.
It’s not just about parts; it’s about engineering foresight. A well-designed plant component is safer to install, easier to inspect, and lasts longer between shutdowns.
Scan What You See — Not What You Think You Have
Over time, every wash plant drifts from its original drawings. Field welds, retrofits, and corrosion mean that “as-built” and “as-exists” are rarely the same thing.
That’s where LiDAR scanning transforms maintenance. Using sub-millimetre accuracy, 3D laser scans capture your plant exactly as it stands — every pipe spool, every chute, every bolt hole.
With this data, our engineers can:
Overlay new models directly into your point cloud to confirm fit-up before fabrication.
Identify alignment errors, corrosion zones, and clearance conflicts before shutdowns.
Generate true digital twins that allow for predictive maintenance and simulation.
LiDAR scanning isn’t just a measurement tool; it’s an insurance policy against rework and lost production.
Corrosion: The Hidden Killer in Every CHPP
Coal and water don’t just move material — they create acidic environments that eat through untreated or aging steel. In sumps, launders, and under conveyors, corrosion silently compromises strength until a structure is no longer safe to walk on.
Regular inspections are the first line of defence. At Hamilton By Design, we recommend combining:
Daily visual checks by operators for surface rust and coating damage.
Thickness testing during shutdowns to track wall loss on chutes and pipes.
3D scan comparisons every 6–12 months to quantify deformation and corrosion in critical structures.
With modern tools, you can see corrosion coming long before it becomes a failure.
From Data to Decision: Predictive Maintenance in Action
A coal wash plant produces a river of data — motor loads, vibration levels, pump pressures, liner thickness, and flow rates. The key is turning that data into insight.
By integrating scanning results, maintenance records, and sensor data, plant teams can identify trends that point to future breakdowns. For example:
Vibration trending can reveal bearing fatigue weeks before failure.
Load monitoring can detect screen blinding or misalignment.
Scan data overlays can show sagging supports or displaced chutes.
When you understand what your plant is telling you, you move from reacting to problems to predicting and preventing them.
Shutdowns: Planned, Precise, and Productive
Every shutdown costs money — the real goal is to make every hour count. The best shutdowns start months ahead with validated design data and prefabrication QA.
Before you cut steel or mobilise cranes, every component should be digitally proven to fit. Trial assemblies, lifting studies, and bolt access checks prevent costly surprises once you’re on the clock.
At Hamilton By Design, our process combines:
LiDAR scanning to confirm as-built geometry.
SolidWorks modelling and FEA for mechanical verification.
Pre-installation validation to ensure bolt holes, flanges, and lift paths align on day one.
That’s how you replace chutes, spools, and launders in a fraction of the usual time — safely, and with confidence.
The Payoff: Reliability You Can Measure
The plants that invest in engineering-led maintenance see results that are tangible and repeatable:

Few regions in Australia represent heavy industry quite like Newcastle and the Hunter Valley. From the coal mines at Bengalla and Mount Thorley, to the power stations at Bayswater and Eraring, to the Port of Newcastle’s massive shiploaders and conveyors, this region has powered Australia for generations.
But with age, complexity, and constant upgrades come challenges:
Outdated drawings
Tight shutdown schedules
Complex brownfield modifications
Difficult site access
That’s where 3D scanning and LiDAR modelling are transforming how industrial projects are designed, verified, and delivered — ensuring every bolt, beam, and bracket fits perfectly the first time.
At Hamilton By Design, we bring together field experience, digital precision, and local knowledge to help the Hunter’s industries design, maintain, and modernise with confidence.
What Is 3D Scanning — and Why It Matters in Industry
3D laser scanning, also known as LiDAR (Light Detection and Ranging), captures millions of data points across an industrial site to create a precise digital representation — known as a point cloud.
This point cloud forms the foundation of a digital twin of your plant or asset — an exact, measurable 3D environment that engineers can design within using SolidWorks, AutoCAD, or Navisworks.
The result? Every measurement is accurate, every clash is detected before fabrication, and every installation happens exactly as planned.
Why Newcastle and the Hunter Valley Need Scanning More Than Ever
The Hunter is an engineering powerhouse — but much of its infrastructure was built decades ago. Many coal handling plants, power stations, and smelters are now in a constant cycle of refurbishment, retrofit, and compliance upgrade.
The challenges are familiar:
Old 2D drawings don’t reflect today’s reality.
Assets have been modified repeatedly over decades.
Shutdown windows are shrinking.
Every error adds cost and delays production.
By scanning before you design, you remove uncertainty. You don’t guess clearances — you know them. You don’t estimate tie-in points — you model them. You don’t hope it fits — you prove it digitally.
That’s the power of 3D scanning in today’s industrial environment.
Where Scanning Adds Value Across the Hunter’s Industries
⚙️ Power Generation
The Bayswater, Eraring, and Vales Point Power Stations are engineering icons. Upgrades to cooling systems, ducts, platforms, and access structures require millimetre accuracy. 3D scanning ensures:
Every retrofit aligns with existing steelwork and pipework.
Structural interferences are caught before fabrication.
Shutdown work can be completed on time — without rework.
Whether it’s a fan casing replacement or a duct reroute, laser scanning removes the guesswork from aging assets.
⛏️ Coal Handling and CHPP Facilities
The Hunter Valley’s CHPP network — Mount Thorley Warkworth, Ravensworth, Bengalla, Hunter Valley Operations — all depend on reliable mechanical systems. These plants evolve continuously: diverter chutes, screen replacements, conveyors, and wash plant modifications.
Scanning delivers:
Accurate as-built geometry for plant upgrades.
Clash detection between new and existing equipment.
Shutdown planning certainty — no unexpected fit-up issues.
Integration of SolidWorks models directly into point clouds for visual verification.
For CHPP managers and maintenance engineers, 3D scanning is now as essential as the plant itself.
⚓ Port of Newcastle and Coal Export Terminals
Newcastle’s port is the lifeline of the Hunter’s economy. Facilities such as Port Waratah Coal Services (PWCS), Newcastle Coal Infrastructure Group (NCIG), and Carrington Terminal handle massive volumes of coal every hour.
The complexity of these sites — shiploaders, conveyors, gantries, and stacker-reclaimers — demands accuracy during maintenance and upgrade works. 3D scanning supports:
Shiploader upgrades and boom extensions.
Conveyor and transfer tower alignment checks.
Wharf structure condition monitoring.
Integration with mechanical and electrical systems.
By scanning before modification, downtime is reduced, safety improves, and project teams gain total confidence in every fit-up.
🏭 Aluminium and Heavy Manufacturing
At Tomago Aluminium Smelter, precision is everything. The scale of the site — from potlines to switchyards — makes manual measurement impractical and unsafe.
Laser scanning captures geometry accurately across large areas, enabling:
Retrofit planning without full shutdowns.
Clearance checks for cranes, ducts, and potline infrastructure.
Digital twins for long-term maintenance and asset management.
Beyond Tomago, manufacturers in Waratah, Beresfield, and Thornton use scanning to validate jigs, fixtures, and workshop layouts — ensuring local fabrication accuracy that matches site requirements.
🔋 Emerging Energy and Infrastructure
As the Hunter region transitions toward renewable and low-emission industries, scanning plays a critical role in planning new infrastructure around existing sites. This includes:
Hydrogen and gas pipeline tie-ins.
Solar and battery installations near existing grid connections.
Conversion of existing power plant structures for new technology.
Accurate point-cloud data ensures new energy meets old infrastructure safely and efficiently.
From Field to Fabrication: The Hamilton By Design Process
At Hamilton By Design, our 3D scanning workflow is built around practical, industrial needs:
Site Scan & Data Capture Using high-precision LiDAR scanners, we safely capture full site geometry in hours, not weeks. Scans are performed during operation or short shutdowns, without interrupting production.
Point Cloud Registration & Processing Multiple scans are aligned to create a unified, accurate model of your facility. The result is a true “digital twin” of your asset, complete with millimetre accuracy.
SolidWorks Modelling & Integration Our design team converts scan data into fully functional 3D models — chutes, pipework, platforms, or structural frames — ready for fabrication.
Clash Detection & Design Validation Every new design is tested within the digital twin, ensuring it fits the first time.
Fabrication Drawings & e-Drawings Detailed 2D and 3D deliverables are provided for fabricators, site crews, and certifiers — ensuring seamless communication between design and construction.
Why Local Expertise Matters
Many engineering firms offer scanning — but few understand what it takes to work on a live plant in the Hunter Valley.
Hamilton By Design combines trade experience, mechanical design, and regional understanding. We’ve worked with the same assets, fabricators, and contractors who keep the region’s power, port, and manufacturing industries running.
We design for real fabrication conditions — using Australian Standards, local materials, and practical build methods. That means fewer redesigns, faster turnarounds, and safer installations.
Safety and Access: Scanning Without Shutdowns
Traditional site measurement often means working at heights, in confined spaces, or around operating equipment. 3D scanning eliminates those risks.
Our scanners capture data safely from the ground — even in restricted or hazardous areas. This not only improves safety but also allows projects to continue without halting production.
For large plants like Eraring or PWCS, scanning entire structures during live operation is now standard practice — enabling ongoing maintenance and long-term asset integrity planning.
Case Example: Port Upgrade Without Rework
A local contractor approached Hamilton By Design for a conveyor and tower modification project at the Port of Newcastle. Existing drawings were decades old, and the structure had been modified repeatedly.
We performed a 3D scan of the tower and adjacent conveyors, capturing the as-built geometry in one day. The resulting model revealed several misalignments between the planned chute and existing supports. By correcting these in SolidWorks before fabrication, the contractor avoided at least 48 hours of site rework and kept the shutdown on schedule.
That’s measurable ROI — precision that pays for itself.
The ROI of 3D Scanning in Heavy Industry
A single hour of lost production at a CHPP or power station can cost $20,000 to $50,000. A single day’s delay can exceed $500,000 in lost revenue and labour costs.
3D scanning reduces that risk by eliminating rework and ensuring every component fits right the first time. Typical return on investment (ROI):
Scanning cost: <1% of total project value.
Rework savings: 3–10% of total cost.
Downtime reduction: 1–3 days saved per shutdown.
When accuracy drives reliability, 3D scanning isn’t an expense — it’s insurance.
Supporting the Hunter’s Future
Newcastle and the Hunter Valley are evolving — from coal and power to renewables, advanced manufacturing, and logistics. But one thing hasn’t changed: the region’s foundation in engineering, precision, and hard work.
Hamilton By Design supports that legacy with the next generation of technology — scanning, digital modelling, and mechanical design that keep the region’s assets efficient, safe, and ready for the future.
We’re not an offshore CAD vendor. We’re local engineers who’ve worked in the field, understand your equipment, and speak the same language as your crews.

Every shutdown comes with pressure — time, budget, and safety. When mechanical upgrades or maintenance are based on outdated drawings or manual measurements, the risk of error skyrockets. A misaligned chute, an incorrectly measured pipe, or a bracket that doesn’t quite fit can turn a planned three-day outage into a five-day scramble. In industries where every hour offline costs tens of thousands of dollars, guesswork is expensive.
3D Laser Scanning: Seeing the Plant as It Really Is
That’s where 3D laser scanning and LiDAR technology change the game. Using a FARO or similar high-accuracy scanner, Hamilton By Design captures millions of data points in a matter of minutes — creating a precise digital replica of your plant or structure. This point cloud model forms the foundation for all design work. Every pipe, beam, and bracket is located exactly where it exists in the real world, not where an old drawing says it should be.
From Scan to SolidWorks: Accurate Models, Confident Designs
Once the scan is complete, the data is reverse-modelled into SolidWorks or similar 3D design environments. This means upgrades, chutes, handrails, and structural supports can be designed within the scanned environment — guaranteeing they fit perfectly on installation day. Our clients use this workflow to plan shutdowns with confidence, knowing that every fabricated part will bolt straight in.
Eliminating Fit-Up Errors and Rework
Traditional upgrade projects rely on tape measures, rough sketches, or outdated general arrangement drawings. Even a 10 mm error can cause weeks of rework once site access is restricted. With 3D scanning, those errors disappear. Before fabrication begins, engineers can check for:
Clashes and interferences between new and existing plant structures.
Clearances for maintenance and access.
Alignment with conveyors, supports, and existing chutes.
That level of insight is impossible with 2D drawings alone.
Shorter Shutdowns, Safer Teams
Fewer surprises mean faster, safer installations. When every component is designed and verified within the scanned model, shutdown crews spend less time cutting, grinding, or reworking in the field. That’s not only a productivity win, it’s a safety win — fewer sparks, less manual handling, and minimal hot work in confined spaces.
Applications Across Mining and Processing
Hamilton By Design’s scanning and modelling process is trusted across the Bowen Basin, Surat Basin, Hunter Valley, and Central West NSW. Typical projects include:
Conveyor realignments — ensuring belt runs are perfectly centred before shutdown.
Pipework and pump station retrofits — avoiding rework when tie-ins occur.
Structural verification — validating as-built conditions before new platforms or walkways are installed.
Real-World ROI
Clients routinely report saving days of downtime and thousands in rework costs by scanning before fabrication. When you consider that a typical CHPP shutdown might cost $20,000–$50,000 per hour in lost production, the return on investment is obvious. A few hours spent scanning can mean days of avoided delay.
Stop Guessing, Start Scanning
If your next shutdown involves tight spaces, limited access, or unknown conditions — don’t rely on old drawings or assumptions. Hamilton By Design provides LiDAR scanning, point-cloud modelling, and SolidWorks-based mechanical design to ensure your upgrades install exactly as intended.

Safety and Precision in Mechanical Engineering Lifts
In the fast-paced world of Sydney construction and infrastructure, precision lifting is an everyday necessity. From hoisting prefabricated modules on high-rise towers to positioning steel frameworks and heavy plant components, each lift depends on one critical factor — the integrity of the lifting device.
A mechanical engineering lift is more than just machinery; it’s the result of careful design, analysis, and compliance with national safety standards. The Australian Standard AS 4991: Lifting Devices provides the engineering framework to ensure that every lifting beam, clamp, and spreader frame is designed, tested, and certified for safe performance.
In the dynamic environment of Sydney’s construction and manufacturing sectors, adhering to AS 4991 is not only a compliance issue — it’s essential to safety, reliability, and professional reputation.
What AS 4991 Means for Mechanical Engineering in Sydney
AS 4991: Lifting Devices is the Australian benchmark for the design, manufacture, proof testing, and maintenance of all mechanically engineered lifting attachments used with cranes and hoists.
It covers:
Design verification by qualified engineers
Proof load testing (typically 1.5 times the Working Load Limit)
Identification markings such as WLL, serial number, and manufacture date
Regular inspection and maintenance schedules
Documented certification and traceability
For Sydney-based mechanical engineering projects — from Parramatta’s commercial developments to the infrastructure of the Eastern Suburbs — these requirements ensure every lift is carried out with confidence and safety.
The Role of Mechanical Engineers in Safe Lifting
Mechanical engineers play a vital role in ensuring every lifting device performs predictably under real-world conditions. Each lifting beam, frame, or clamp must be:
Designed for static and dynamic loading
Resistant to fatigue, buckling, and corrosion
Built from materials tested for strength and durability
Verified through engineering analysis and proof testing
By applying AS 4991, mechanical engineers in Sydney create lifting devices that not only meet technical standards but also withstand the operational demands of construction, mining, and industrial settings across New South Wales.
Why Non-Compliance is Never Worth the Risk
Sydney’s worksites are under strict safety scrutiny, and incidents involving lifting equipment failures have resulted in serious injuries, fatalities, and prosecutions.
Examples from across Australia include:
Unmarked or uncertified lifting beams that failed under load due to poor design.
Vacuum lifters that detached unexpectedly after seals deteriorated from lack of inspection.
Improvised lifting points on machinery leading to crush injuries and WHS enforcement actions.
These events share a common cause: failure to meet the design, inspection, and documentation requirements of AS 4991.
For any mechanical engineering lift in Sydney, non-compliance risks not just equipment damage but also:
Work Health and Safety (WHS) prosecutions
Civil negligence claims
Loss of accreditation and contracts
Damage to professional reputation
Compliance as a Legal and Professional Obligation
While AS 4991 is not legislation, it defines the expected standard of care under Australia’s WHS laws. Regulators such as SafeWork NSW use compliance with standards like AS 4991 as evidence of due diligence.
For mechanical engineers, fabricators, and construction managers, compliance means:
Designs verified by competent engineers
Devices tested and certified to meet load requirements
Inspection records that prove ongoing safety
Training to ensure operators understand correct usage
In Sydney’s competitive engineering market, adherence to AS 4991 isn’t just about avoiding penalties — it’s about demonstrating leadership in professional safety.
Building a Culture of Inspection and Traceability
A key part of AS 4991 is documentation. Each lifting device should have a design verification report, proof load certificate, and inspection record. This traceability ensures that every lift on a Sydney site can be traced back to certified engineering.
Companies should maintain:
A register of lifting devices with serial numbers and inspection dates
Clear tagging systems for quick identification
Routine re-certification for high-use environments
Operator awareness training on compliance indicators
These processes turn safety standards into practical habits that protect workers and ensure smooth site operations.
Sydney is a hub of engineering innovation, with advanced tools like 3D scanning, LiDAR, and Finite Element Analysis (FEA) enhancing how lifting devices are designed and validated.
At Hamilton By Design, our mechanical engineers use these technologies to create custom lifting systems for complex sites across Sydney — from tight urban projects in Chatswood and Parramatta to industrial installations in the Inner West.
Yet, even with the latest modelling tools, every design is checked against AS 4991 to guarantee that each lift meets both engineering and safety expectations.
Conclusion: Lifting Sydney Safely
In mechanical engineering, safety begins long before the crane hook rises. It starts with standards — and in Australia, AS 4991 is the foundation.
For every mechanical engineering lift in Sydney, compliance ensures more than safety: it provides reliability, traceability, and peace of mind. By following the standard, engineers not only protect lives but also elevate the quality and professionalism of Sydney’s construction and manufacturing industries.
At Hamilton By Design, our commitment is simple: lift Sydney safely, lift with engineering excellence, and lift to the standard — AS 4991.
