Why Shutdown Parts Don’t Fit — And How 2 mm LiDAR Scanning Stops the Rework

When Parts Don’t Fit, Shutdowns Fail

Every shutdown fitter, maintenance crew member, and supervisor has lived the same nightmare:

A critical part arrives during shutdown.
The old part is removed.
Everyone gathers, ready to install the new one.
Production is waiting.
The pressure is on.

And then—
the part doesn’t fit.

Not 2 mm out.
Not 10 mm out.
Sometimes 30–50 mm out, wrong angle, wrong bolt pattern, wrong centreline, or wrong geometry altogether.

The job stops.
People get frustrated.
Supervisors argue.
Fitters cop the blame.
The plant misses production.
And someone eventually says the words everyone hates:

“Put the old worn-out chute back on.”

This blog is about why shutdowns fall apart like this… and how 2 mm LiDAR scanning finally gives fitters a system that gets it right the first time.

The Real Reason Parts Don’t Fit

Most shutdown failures have nothing to do with the fitter, nothing to do with the workshop, and nothing to do with the installation crew.

Parts don’t fit because:

Wrong measurements
Bad drawings
Outdated as-builts
Guesswork
Fabricators “eyeballing” dimensions
Cheap non-OEM parts purchased without geometry verification
Designers who have never seen the site
High staff turnover with no engineering history
Wear profiles not checked
Intersection points impossible to measure manually

Fitters are then expected to make magic happen with a tape measure and a grinder.

It’s not fair. It’s not professional. And it’s completely avoidable.

Shutdown Pressures Make It Even Worse

When a part doesn’t fit during a shutdown:

The entire job stalls
Crews stand around waiting
The supervisor gets hammered
The fitter gets the blame
Other shutdown tasks cannot start
The clock ticks
Production loses thousands per hour
Everyone becomes stressed and angry

And the worst part?

You were only replacing the part because the existing one was worn out.
Now you’re bolting the worn-out one back on.

This isn’t good enough.
Not in 2025.
Not in heavy industry.
Not when there is technology that eliminates this problem completely.

Why Manual Measurement Fails Every Time

Fitters often get asked to measure:

Inside chutes
Wear sections
Pipe spools with intersection points
Tanks too large to measure from one position
Walkways too long for tape accuracy
Geometry with no records
Components 10+ metres above ground
Hard-to-reach bolt patterns
Angles and centrelines distorted by wear

But some measurements simply cannot be taken safely or accurately by hand.

You can’t hang off an EWP 20 metres up measuring a worn flange angle.
You can’t crawl deep inside a chute trying to measure intersecting surfaces.
You can’t take a 20-metre walkway measurement with a tape measure and hope for precision.

This is not a measurement problem.
This is a method problem.

Manual measurement has hit its limit.
Shutdowns have outgrown tape measures.

This Is Where 2 mm LiDAR Scanning Changes Everything

Hamilton By Design uses 2 mm precision LiDAR scanning to capture the exact geometry of a site — even in areas that are:

Too high
Too big
Too unsafe
Too worn
Too complex
Too tight
Too distorted to measure manually

From the ground, up to 30 metres away, we can capture:

Wear profiles
Flange positions
Bolt patterns
Pipe centrelines
Chute geometry
Conveyor interfaces
Complex intersections
Ductwork transitions
Mill inlet/outlet shapes
Tank dimensions
Walkway alignment
Structural deflection
Existing inaccuracies

No tape measure. No guesswork. No EWP. No risk.

The result is a perfect 3D point cloud accurate within 2 mm — a digital version of real life.

2 mm Scanning + Fitter-informed Design = Parts That Fit First Time

This is where Hamilton By Design is different.

We don’t just scan and hand the files to a drafter who’s never set foot on-site.

We scan and your parts are modelled by someone who:

Has been a fitter
Understands how parts are installed
Knows what goes wrong
Knows how to design parts that actually fit
Knows where shutdowns fail
Knows what to check
Knows what NOT to trust
And most importantly — knows where the real-world problems are hidden

This fitter-informed engineering approach is why our parts fit the first time.

And why shutdown crews trust us.

Digital QA Ensures Fabrication Is Correct Before It Leaves the Workshop

Once the new chute, spool, or component is modelled, we run digital QA:

Fit-up simulation
Clash detection
Tolerance analysis
Wear profile compensation
Reverse engineering comparison
Bolt alignment verification
Centreline matching
Flange rotation accuracy
Structural interface checks

If something is out by even 2–3 mm, we know.

We fix it digitally — before the workshop cuts steel.

This stops rework.
This stops shutdown delays.
This stops blame.
This stops stress.

This is the future of shutdown preparation.

Accuracy of 3D LiDAR Scanning With FARO

When the Part Fits, Everything Runs Smooth

Here’s what actually happens when a chute or spool fits perfectly the first time:

The plant is back online faster
No rework
No reinstalling old worn-out parts
No arguing between fitters and supervisors
No unexpected surprises
No extra access equipment
No late-night stress
No grinding or “making it fit”
Other shutdown tasks stay on schedule
Everyone looks good
Production trusts the maintenance team again

Shutdowns become predictable.
Fitters become heroes, not last-minute problem-solvers.

Shutdown Example (Anonymous but Real)

A major processing plant needed a large chute replaced during a short shutdown window.
Access was limited.
The geometry was distorted.
Measurements were impossible to take safely.
The workshop needed exact dimensions, fast.

Hamilton By Design scanned the entire area from the ground — no EWP, no risk.

We produced:

Full 2 mm point cloud
As-built 3D model
New chute design
Digital fit-up validation
Workshop-ready drawings

The new chute arrived on site.
The old chute came out.
The new chute went straight in.
Zero rework.
Zero stress.
Plant online early.

The supervisor called it the smoothest shutdown they’d had in 10 years.

Why Fitters Should Reach Out Directly

Sometimes fitters know more about what’s really happening on-site than anyone in the office.

Fitters see the problems.
Fitters carry the blame.
Fitters deal with the rework.
Fitters just want parts that fit.

So we’re making this simple:

If you’re tired of fitting parts that don’t fit —
If you’re tired of fixing other people’s mistakes —
If you’re tired of shutdown stress —

Call Hamilton By Design.

We scan it.
We model it.
We get it right.
Every time.

Stop Reacting — Start Engineering

How Smart Mechanical Strategies Extend CHPP Life

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:

Improvement Area	Typical Gain
Reduced unplanned downtime	30–40%
Increased liner lifespan	25–50%
Shorter shutdown duration	10–20%
Fewer fit-up issues and rework	60–80%
Improved safety performance	20–30%

Reliability isn’t luck — it’s engineered.

Mechanical Engineering Lift Sydney: Why Standards Like AS 4991 Matter

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.

Illustrated infographic explaining AS 4991 mechanically engineered lifting devices, showing engineering design steps, safe lifting practices, compliance outcomes, and non-compliance risks, with Sydney landmarks in the background

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.

Mechanical Engineering Lift Sydney: Innovation Meets Safety

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.

Building Sydney Smarter: How 3D Scanning and LiDAR Are Transforming Construction Accuracy

A New Era of Construction Accuracy in Sydney

Sydney’s construction industry is booming — from commercial towers and infrastructure upgrades to industrial developments and complex refurbishments. But as sites become more congested and designs more complex, achieving perfect alignment between fabricated and installed components has never been more challenging.

That’s where 3D scanning and LiDAR technology come in. At Hamilton By Design, we provide high-precision digital capture and 3D modelling services that ensure every element of your construction project fits seamlessly together, saving time, cost, and effort onsite.

Capturing the Real Site with LiDAR Scanning

Using LiDAR (Light Detection and Ranging) scanners, we capture millions of laser measurements per second to create an exact 3D digital record — known as a point cloud — of your construction site or structure.

This means we can document existing conditions, monitor progress, and verify installations with millimetre-level precision. For Sydney builders, engineers, and contractors, that data eliminates the guesswork and drastically reduces costly clashes and rework later on.

From Point Cloud to 3D Model

Once the LiDAR data is captured, it’s processed into detailed 3D CAD and BIM models compatible with leading design software such as Revit, AutoCAD, SolidWorks, and Navisworks.

These accurate models allow design teams to:

Validate and update as-built conditions before fabrication
Detect clashes and misalignments before installation
Plan modifications and extensions with confidence
Coordinate between mechanical, structural, and architectural disciplines

By working from a true digital twin of your Sydney site, you can be sure every part — from prefabricated frames to pipe runs — will fit exactly where it should.

Why Sydney Construction Projects Are Turning to 3D Scanning

Reduced Rework: Identify design and fabrication issues before they reach site.
Improved Safety: Capture high or restricted areas without scaffolding or shutdowns.
Shorter Installation Times: Minimise downtime and delays during fit-up.
Precise Documentation: Maintain accurate records for QA and handover.
Better Collaboration: Integrate real-world data into your BIM environment.

From commercial fit-outs to infrastructure projects across Greater Sydney, 3D scanning provides a single source of truth for every stakeholder.

Typical Sydney Projects Using LiDAR and 3D Modelling

Hamilton By Design supports a range of construction and engineering clients, including:

Commercial and residential developments in the CBD and inner suburbs
Industrial plant upgrades across Western Sydney
Transport and infrastructure projects under NSW Government programs
Refurbishment and brownfield works requiring detailed as-built verification

Each project benefits from faster delivery, greater precision, and stronger communication between designers, builders, and clients.

Partner with Hamilton By Design

If you’re working on a Sydney construction or infrastructure project and need accurate 3D site data, as-built modelling, or fit-up verification, Hamilton By Design can help.

Chute Design in the Mining Industry

Infographic showing Hamilton By Design’s engineering workflow, including millimetre-accurate LiDAR reality capture, material-flow simulation, optimised chute designs, and safer, more efficient production outcomes. Two workers in PPE highlight reliable design and longer liner life, with icons representing time, cost and quality benefits.

Getting Coal, Hard Rock, and ROM Material Flow Right

Chute design is one of the most critical yet challenging aspects of mining and mineral processing. Whether you are handling coal, hard rock ore, or raw ROM material, chutes and transfer stations are the unsung workhorses of every operation. When designed well, they guide material smoothly, minimise wear, and keep conveyors running. When designed poorly, they cause blockages, spillage, excessive dust, and expensive downtime.

Modern chute design has moved far beyond rules of thumb and back-of-the-envelope sketches. Today, successful projects rely on accurate as-built data, particle trajectory analysis, and advanced Discrete Element Method (DEM) simulation to predict, visualise, and optimise material flow before steel is cut. In this article, we explore why these tools have become essential, how they work together, and where software can — and cannot — replace engineering judgement.

Illustration showing common problems with poorly designed material-handling chutes. A chute discharges material onto a conveyor while issues are highlighted around it: unpredictable material flow, material spillage, maintenance challenges, high wear, blockages, and dust and noise. Warning icons for downtime and cost appear on the conveyor, and workers are shown dealing with the resulting hazards and maintenance tasks.

The Challenge of Chute Design

Coal and hard rock have very different flow behaviours. Coal tends to be softer, generate more dust, and be prone to degradation, while hard rock is more abrasive and can damage chutes if impact angles are not controlled. ROM material adds another level of complexity — oversize lumps, fines, and moisture variation can cause hang-ups or uneven flow.

Chute design must balance several competing objectives:

Control the trajectory of incoming material to reduce impact and wear
Prevent blockages by maintaining flowability, even with wet or sticky ore
Manage dust and noise to meet environmental and workplace health requirements
Fit within existing plant space with minimal modification to conveyors and structures
Be maintainable — liners must be accessible and replaceable without excessive downtime

Meeting all these goals without accurate data and simulation is like trying to design in the dark.

Illustrated graphic showing a tripod-mounted 3D laser scanner capturing millimetre-accurate as-built data in an industrial plant with conveyors and walkways. Speech bubbles highlight issues such as “Outdated drawings don’t tell the full story” and “Modifications rarely get documented.” The scan data is shown being visualised on a laptop, with notes describing full coverage of conveyors, walkways, and services. Benefits listed along the bottom include faster data collection, fewer site revisits, safer shutdowns, accurate starting point for design simulation, and safer outcomes that ensure designs fit first time.

Capturing the Truth with 3D Scanning

The first step in any successful chute project is to understand the as-built environment. In many operations, drawings are outdated, modifications have been made over the years, and the real plant geometry may differ from what is on paper. Manual measurement is slow, risky, and often incomplete.

This is where 3D laser scanning changes the game. Using tripod-mounted or mobile LiDAR scanners, engineers can capture the entire transfer station, conveyors, surrounding steelwork, and services in a matter of hours. The result is a dense point cloud with millimetre accuracy that reflects the true state of the plant.

From here, the point cloud is cleaned and converted into a 3D model. This ensures the new chute design will not clash with existing structures, and that all clearances are known. It also allows maintenance teams to plan safe access for liner change-outs and other work, as the scanned model can be navigated virtually to check reach and access envelopes.

Understanding Particle Trajectory

Once the physical environment is known, the next challenge is to understand the particle trajectory — the path that material takes as it leaves the head pulley or previous transfer point.

Trajectory depends on belt speed, material characteristics, and discharge angle. For coal, fine particles may spread wider than the coarse fraction, while for ROM ore, large lumps may follow a ballistic path that needs to be controlled to prevent impact damage.

Accurately modelling trajectory ensures that the material enters the chute in the right location and direction. This minimises impact forces, reducing wear on liners and avoiding the “splash” that creates spillage and dust. It also prevents the material from hitting obstructions or dead zones that could lead to build-up and blockages.

Modern software can plot the trajectory curve for different loading conditions, providing a starting point for chute geometry. This is a critical step — if the trajectory is wrong, the chute design will be fighting against the natural path of the material.

The Power of DEM Simulation

While trajectory gives a first approximation, real-world flow is far more complex. This is where Discrete Element Method (DEM) simulation comes into play. DEM models represent bulk material as thousands (or millions) of individual particles, each following the laws of motion and interacting with one another.

When a DEM simulation is run on a chute design:

You can visualise material flow in 3D, watching how particles accelerate, collide, and settle
Impact zones become clear, showing where liners will wear fastest
Areas of turbulence, dust generation, or segregation are identified
Build-up points and potential blockages are predicted

This allows engineers to experiment with chute geometry before fabrication. Angles can be changed, ledges removed, and flow-aiding features like hood and spoon profiles or rock-boxes optimised to achieve smooth, controlled flow.

For coal, DEM can help ensure material lands gently on the receiving belt, reducing degradation and dust. For hard rock, it can ensure that the energy of impact is directed onto replaceable wear liners rather than structural plate. For ROM ore, it can help prevent oversize lumps from wedging in critical locations.

🖥 Strengths and Limitations of Software

Modern DEM packages are powerful, but they are not magic. Software such as EDEM, Rocky DEM, or Altair’s tools can simulate a wide range of materials and geometries, but they rely on good input data and skilled interpretation.

Key strengths include:

Ability to model complex, 3D geometries and particle interactions
High visualisation power for communicating designs to stakeholders
Capability to run multiple scenarios (different feed rates, moisture contents, ore types) quickly

However, there are limitations:

Material calibration is critical. If the particle shape, friction, and cohesion parameters are wrong, the results will not match reality.
Computational cost can be high — detailed simulations of large chutes with millions of particles may take hours or days to run.
Engineering judgement is still needed. Software will not tell you the “best” design — it will only show how a proposed design behaves under given conditions.

That’s why DEM is best used as part of a holistic workflow that includes field data, trajectory analysis, and experienced design review.

From Model to Real-World Results

When the simulation results are validated and optimised, the design can be finalised. The point cloud model ensures the chute will fit in the available space, and the DEM results give confidence that it will perform as intended.

This means fabrication can proceed with fewer changes and less risk. During shutdown, installation goes smoothly, because clashes have already been resolved in the digital model. Once commissioned, the chute delivers predictable flow, less spillage, and longer liner life.

Why It Matters More Than Ever

Today’s mining operations face tighter production schedules, stricter environmental compliance, and increasing cost pressures. Downtime is expensive, and the margin for error is shrinking.

By combining 3D scanning, trajectory modelling, and DEM simulation, operations can move from reactive problem-solving to proactive improvement. Instead of waiting for blockages or failures, they can design out the problems before they occur, saving both time and money.
