Engineering-Grade LiDAR Scanning

They Don’t Just Scan — They Take Responsibility

Engineering-grade LiDAR scanning is not about collecting point clouds.
It is about taking responsibility for the data that engineering, fabrication, and shutdown decisions are made from.

At Hamilton By Design, engineering-grade LiDAR scanning means the scan is:

Planned by engineers
Verified by engineers
Used directly for design and fabrication
Owned by engineers when it matters

If a scan cannot be confidently designed from, fabricated from, and installed from, it is not engineering grade.

“We’ve seen too many projects fail because everyone assumed the scan was ‘good enough’.
At Hamilton By Design, we don’t just deliver LiDAR data — we take responsibility for whether it can actually be designed and built from.
If we’re involved, someone owns the outcome.”

— General Manager, Hamilton By Design

Why Most LiDAR Scans Fail Engineering Projects

We regularly encounter projects where:

“We trusted the data and got burned.”
“The drawings didn’t match reality.”
“No one wanted to own it when it went wrong.”

In most cases, the issue isn’t the scanner.

The issue is that the scan was treated as a data product, not an engineering input.

Scan-only services deliver point clouds.
Engineering-grade LiDAR delivers confidence, accountability, and defensible outcomes.

What Makes LiDAR “Engineering-Grade”

Engineering-grade LiDAR scanning is defined by how the scan is controlled, interpreted, and used, not by scan density or marketing claims.

1. Engineering-Led Scan Planning

Before scanning begins, engineers define:

What must fit together
What tolerances actually matter
What will be fabricated, replaced, or installed
Where shutdown or safety risk exists

This ensures the scan is fit-for-purpose, not just visually impressive.

2. Accuracy Is Verified — Not Assumed

Engineering-grade scanning includes:

Controlled scan resolution and overlap
Registration reviewed using engineering judgement
Scale and geometry checked against known site features
Accuracy assessed relative to design intent

A dense point cloud does not guarantee engineering reliability.

3. Engineering Interpretation of Brownfield Reality

Real industrial assets are rarely perfect. They are:

Worn
Modified
Repaired
Out of square

Engineering-grade LiDAR scanning includes:

Interpretation of deformation and wear
Identification of unreliable geometry
Clear documentation of assumptions and exclusions

This is where engineering experience prevents downstream rework.

4. Data That Works Directly in CAD & Fabrication

Engineering-grade LiDAR data is:

Structured for SolidWorks and Inventor
Used directly for fabrication-ready models and drawings
Suitable for interference checks and constructability reviews

If a scan cannot be confidently used in CAD, it is not engineering-grade.

Point Clouds – 3D Scans – Engineering Quality – Past Projects

5. Ownership When It Matters Most

Engineering-grade LiDAR scanning means:

One party owns the scan-to-design interface
Assumptions are explicit and traceable
Engineering judgement is applied — not avoided

This is critical when:

Shutdown windows are tight
Fabrication is off-site
Parts must fit together first time
Designs must be defensible in audits or reviews

Our clients:

Why Fabricators and Shutdown Teams Value This Approach

Engineering-grade LiDAR scanning enables:

Seamless delivery where parts fit together
Reduced RFIs and site rework
Predictable shutdown execution
Fit-first-time fabrication

We design with fabrication and installation in mind, because that is where projects succeed — or fail.

Where Engineering-Grade LiDAR Is Essential

Mining and minerals processing facilities
Power generation and utilities
Manufacturing and process plants
Brownfield upgrades and tie-ins
Shutdown-critical replacement works
Reverse engineering of undocumented assets
Safety-critical access platforms and structures

Engineering-Grade LiDAR Is Risk Management

At Hamilton By Design, LiDAR scanning is not sold as a standalone service.

It is part of an engineering-led delivery model that connects:

Reality capture
Mechanical and structural design
Fabrication documentation
Installation confidence

We do not compete on lowest scan cost.
We compete on ownership, accountability, and outcome.

3D LiDAR Scanning Solutions Australia: Capturing Engineering-Grade Accuracy for Mining, Industrial & Infrastructure Projects

3D LiDAR scanning has rapidly become one of Australia’s most valuable engineering tools — and for good reason. From mining CHPPs to power stations, manufacturing plants, processing facilities, marine infrastructure, and complex brownfield upgrades, LiDAR delivers accuracy, clarity, and reliability that traditional measurement methods simply can’t match.

Across Australia’s most demanding industrial regions — the Hunter Valley, Bowen Basin, Pilbara, Mount Isa, Central Coast, Sydney, Adelaide, and beyond — Hamilton By Design provides engineering-grade 3D LiDAR scanning, mechanical design, and full digital-engineering workflows that help clients minimise shutdown duration, eliminate rework, and make better decisions.

This page explains what 3D LiDAR scanning is, why it matters, and how it delivers real, measurable benefits to Australian mining, industrial, and manufacturing operations.

What Is 3D LiDAR Scanning?

LiDAR (Light Detection and Ranging) uses laser pulses to measure millions of points per second, capturing the exact geometry of equipment, structures, and environments. The result is a high-resolution point cloud that serves as a digital replica of the asset — precise down to the millimetre.

Hamilton By Design uses FARO engineering-grade scanners delivering:

±1–2 mm accuracy
Full-colour point clouds
Safe, fast external and internal scanning
High-resolution data suitable for mechanical design and fabrication

This accuracy allows us to model steelwork, chutes, conveyors, piping, tanks, equipment frames, building interiors, structural interfaces, and entire wash plants with confidence.

Why Australian Industries Are Turning to LiDAR

Australia’s mining, energy, and industrial sectors face unique pressures:
tight shutdown windows, ageing infrastructure, safety constraints, limited access, and the constant demand for more accurate data.

LiDAR scanning solves these challenges by offering:

1. Fast, Safe, Non-Contact Measurement

No climbing into hazardous areas.
No lengthy tape measurements.
No assumptions.

LiDAR captures everything from a safe distance — ideal for CHPPs, crushing circuits, transfer towers, power stations, and restricted plant rooms.

2. Zero Guesswork in Brownfield Engineering

Brownfield sites are messy. Nothing is straight, square, or built to the original drawing anymore.

With LiDAR:

Misalignment is captured
Deformation is visible
Corrosion and sag are measurable
Legacy drawings can be validated or corrected

This drastically reduces design error across upgrades, fabrication, and shutdown works.

3. Millimetre-Accurate 3D Models for Fabrication

After scanning, Hamilton By Design converts the point cloud into:

SolidWorks 3D models
GA drawings
Fabrication drawings
DXF profiles
Shop-ready detail packs

Fabricators love it because parts fit the first time, and rework is almost eliminated.

4. Better Shutdown Planning

LiDAR scanning provides clear digital visibility of:

Access routes
Lifting paths
Structural constraints
Tie-in locations
Clash points

This leads to safer, faster, more predictable shutdown execution.

5. Digital Twins for Long-Term Asset Management

A structured point cloud becomes a digital baseline for future planning.
Clients use it for:

Condition monitoring

3-D Lidar Scanning Hunter Valley: Transforming Industrial Projects with Accuracy, Safety and Engineering Confidence

The Hunter Valley is one of Australia’s most strategically important industrial regions. It supports large mining operations, CHPP facilities, fabrication workshops, energy infrastructure, civil projects and heavy manufacturing. These industries depend on precision, safety and efficient project delivery — yet most operate in aging brownfield environments where original drawings are outdated, equipment has shifted over time, and modifications have occurred for decades without accurate documentation.

In environments like these, traditional measuring methods often fail to provide the precision required for confident engineering and fabrication. This is why 3-D Lidar scanning in the Hunter Valley has become a critical tool for engineers, supervisors, fabricators and project managers. It captures the real-world site conditions with millimetre accuracy, creating a digital foundation for smarter, safer and more efficient project execution.

This article explores the benefits, pros and cons of 3-D Lidar scanning, and explains why the Hunter Valley is uniquely positioned to gain massive value from this technology.

Understanding 3-D Lidar Scanning

3-D Lidar (Light Detection and Ranging) scanning is a non-contact measurement technology that uses lasers to capture millions of points in seconds. The scanner emits laser pulses and measures the return time to determine distances, building a dense “point cloud” of the environment.

This point cloud is a precise 3-D representation of:

Structural steel
Conveyors and transfer towers
Chutes, bins and hoppers
Tanks, pipework and mechanical equipment
Platforms, walkways and buildings
Industrial plant rooms and process areas

Once captured, this digital data becomes the foundation for engineering models, fabrication drawings, digital fit checks and project planning.

Why 3-D Lidar Scanning Matters in the Hunter Valley

The Hunter Valley contains some of the most complex and heavily used industrial assets in Australia. Many facilities have been in operation for decades, and almost all have undergone modifications, expansions and repairs. Over time, the real-world geometry diverges significantly from the old drawings stored on paper or outdated CAD files.

This creates major challenges:

Measurements taken by hand are inaccurate or unsafe
Shutdown windows are extremely tight
Fabricators rely on precise data to avoid costly rework
Engineers require true geometry for load calculations and interface design
Supervisors need reliable information to scope replacement work

3-D Lidar scanning provides a millimetre-accurate representation of what exists onsite, removing guesswork and supporting engineering best practice.

The Benefits of 3-D Lidar Scanning in the Hunter Valley

1. Millimetre Accuracy Improves Engineering Outcomes

In heavy industrial environments, small measurement errors can create large, expensive problems. Structural misalignment, worn steel, bent frames, sagging conveyors and distorted chutes are all common in brownfield plants.

3-D Lidar scanning captures:

True dimensions
Variations from design
Deformation and misalignment
Complex curved surfaces
Differences caused by wear and tear

Engineers design with confidence because the digital model reflects actual site conditions — not assumptions.

2. Huge Reduction in Rework and Fabrication Errors

Fabricators in Singleton, Muswellbrook, Rutherford, Tomago and throughout the Hunter region rely on accurate measurements to ensure steel and mechanical components fit the first time.

Without accurate data, common fabrication issues include:

Bolt holes misaligned
Steel members too short or too long
Chutes or hoppers not matching openings
Pipe spools missing clearances
Platforms not sitting square

These problems lead to:

Onsite cutting and welding
Delayed installations
Extended shutdown time
Additional crane costs
Extra labour expenses

3-D Lidar scanning eliminates these risks, ensuring every component is manufactured to match the as-built site geometry.

3. Improved Shutdown Planning and Faster Execution

Mining and CHPP shutdowns in the Hunter Valley operate under strict time constraints. Any unexpected measurement issue can cause delays affecting production and safety.

With 3-D Lidar scanning:

Scope is defined accurately before shutdown
Fabrication is completed correctly the first time
Digital fit checks identify problems early
Installation is faster and safer

Shutdowns become more predictable and efficient.

4. Massive Safety Improvements

Manual measurement often requires workers to:

Enter confined spaces
Access heights
Work around operating equipment
Lean over conveyors
Navigate dirty, uneven or hazardous areas

3-D Lidar scanning minimises physical access requirements. Technicians can scan large areas from safe positions, reducing:

Fall risks
Pinch-point exposure
Hot-work hazards
Time on elevated structures

This is a major benefit for HSE and maintenance teams across the Hunter Valley.

5. Better Communication, Collaboration and Visualisation

Point clouds and 3-D models make it easier for teams to understand the project environment, especially when stakeholders are spread across:

Mine sites
Fabrication workshops
Design offices
Engineering consultancies
Projects teams and OEM vendors

Digital data allows remote review, reducing the need for repeated site visits and improving decision-making.

6. Ideal for Brownfield Upgrades and Congested Areas

Many Hunter Valley facilities are decades old, with layers of modifications. Clearances are tight, geometry is irregular, and equipment alignment has changed over the years.

3-D Lidar scanning is perfect for:

Transfer towers with layered steel
Congested plant rooms
Pipe networks
Stockpile conveyors
Old building footprints
Complex structural junctions

The scanner captures the complexity instantly and precisely.

Pros and Cons of 3-D Lidar Scanning

While 3-D Lidar scanning is a game-changing tool, it is important to understand both the advantages and limitations.

Hunter Valley Laser Scanning: Transforming Engineering Accuracy Across Mining, Manufacturing and Infrastructure

The Hunter Valley stands as one of Australia’s most important industrial regions, supporting mining, energy, heavy fabrication, processing, manufacturing and major commercial development. Across this diverse landscape, one challenge consistently affects project performance: the need for accurate, reliable and up-to-date site information.

For engineers, maintenance planners, fabricators and construction managers, relying on outdated drawings or manual tape measurements introduces unnecessary risk. Plants evolve over decades. Structures deform. Equipment shifts alignment. Site conditions rarely match legacy documentation.

This is why Hunter Valley laser scanning has become essential. The ability to capture millimetre-accurate as-built data is transforming how projects are planned, designed and executed—reducing cost, increasing safety and ensuring that every component fits the first time.

Hamilton By Design is proud to support the region with advanced, engineering-grade laser scanning services designed specifically for heavy industry and complex brownfield environments. This article explores how laser scanning works, why the Hunter Valley relies on it, and how it strengthens everything from shutdown planning to fabrication accuracy.

Why the Hunter Valley Depends on Laser Scanning

The Hunter’s operating assets are large, complex and often decades old. Across mines, processing facilities, power stations, port handling infrastructure and manufacturing plants, very few sites match their original drawings.

Typical challenges include:

Numerous undocumented modifications
Wear, deformation and structural movement
Limited or unreliable legacy drawings
Tight shutdown windows
Hazardous access for manual measuring
Brownfield constraints that complicate upgrades

These conditions make traditional measurement methods slow, risky and error-prone. A wrong measurement in a transfer tower, a misaligned conveyor frame, or an incorrect chute dimension can create thousands of dollars in rework and delay.

Hunter Valley laser scanning eliminates these risks completely by capturing the site exactly as it exists today—not as it was decades ago.

How Hunter Valley Laser Scanning Works

Laser scanning uses high-precision LiDAR technology to record millions of data points across structures, equipment and plant areas. These points combine to create a three-dimensional “point cloud”—a highly accurate digital representation of real-world conditions.

The Hamilton By Design workflow typically includes:

1. On-Site Reality Capture

Our laser scanner is deployed across key vantage points to capture the full environment, including:

Structural steel
Conveyors and walkways
Chutes, bins, hoppers and material-handling equipment
Pipework networks
Equipment footprints
Building geometry
Confined or elevated spaces

The capture process is fast, safe and non-intrusive—ideal for operational sites.

2. Registration & Point Cloud Processing

Data from each scan position is aligned into a complete, unified point cloud representing the entire area with millimetre accuracy.

3. Modelling & Analysis

From the point cloud we can create:

True as-built CAD models
Structural layouts
Mechanical assemblies
Pipework geometry
Digital templates for fabrication
Probe measurements for checking clearances and alignment

4. Engineering & Fabrication Support

Once converted into a usable engineering environment, the data supports:

Shutdown planning
Structural redesign
Chute and conveyor optimisation
Digital fit checks
Fabrication drawings
Reverse engineering of worn components

The result is a reliable, verified understanding of your site—available digitally to your entire project team.

Where Hunter Valley Laser Scanning Delivers the Most Value

The unique industrial profile of the Hunter Valley means laser scanning is useful across a broad range of applications. Here are the areas where it delivers the highest impact.

Mining & CHPP Operations

Mining infrastructure in the region is constantly under pressure to operate safely and efficiently. For CHPP upgrades, conveyor realignments, chute replacements and structural modifications, laser scanning provides:

True as-built dimensions
Clearances and offset measurements
Verified alignment data
Digital templates for safe, accurate fabrication
Reduced shutdown duration
Fewer fitment issues onsite

Upgrades become predictable instead of stressful, and fabricators can manufacture with confidence.

Processing Plants & Material-Handling Systems

Transfer towers, bin replacements, screening arrangements and crusher areas often contain congested layouts with poor access. Manual measurement is difficult and unsafe.

Laser scanning solves this by allowing the entire environment to be measured remotely. This supports:

Clash prevention
Redesign of worn systems
Smoother installation
Accurate interface points
Digital verification before fabrication

Heavy Fabrication & Workshop Integration

Fabricators across the Hunter Valley consistently face the same problem: components not fitting onsite due to bad measurements.

Hunter Valley laser scanning ensures:

Perfectly matched bolt hole patterns
Correct flange alignment
True geometry of mating parts
Accurate templates for bending, rolling and welding
Reduced rework and scrap

It is a direct cost saver for both workshops and clients.

Energy, Power Stations & Utilities

Power stations and energy sites require sophisticated maintenance planning. Laser scanning helps engineers:

Document aging structures
Compare deformation over time
Plan retrofits and upgrades
Replace platforms, pipework and supports with confidence
Identify clashes before installation

This improves compliance and reduces risk.

The Real-World Accuracy of 3D LiDAR Scanning With FARO S150 & S350 Scanners

When people first explore 3D LiDAR scanning, one of the most eye-catching numbers in any product brochure is the advertised accuracy. FARO’s Focus S150 and S350 scanners are often promoted as delivering “±1 mm accuracy,” which sounds definitive and easy to rely on for engineering, mining and fabrication work. But anyone who has spent time working with 3D LiDAR scanning in real industrial environments understands that accuracy isn’t a single number — it is a system of interrelated factors.

This article explains what the ±1 mm specification from FARO really means, how accuracy shifts with distance, and what engineers, project managers and clients need to do to achieve dependable results when applying 3D LiDAR scanning on live sites.

Infographic explaining 3D LiDAR scanning accuracy, showing a scanner capturing a building and highlighting factors that affect accuracy such as temperature, atmospheric noise, surface reflectivity and tripod stability. Includes diagrams comparing realistic versus unrealistic ±1 mm accuracy, the impact of distance, environment and registration quality, and notes that large open sites typically achieve ±3–6 mm global accuracy.

1. What FARO’s “±1 mm Accuracy” Really Means in 3D LiDAR Scanning

The ±1 mm number applies only to the internal distance measurement unit inside the scanner. It reflects how accurately the laser measures a single distance in controlled conditions.

It does not guarantee:

±1 mm for every point in a full plant model
±1 mm for every dimension extracted for engineering
±1 mm global accuracy across large multi-scan datasets

In 3D LiDAR scanning, ranging accuracy is just one ingredient. Real-world accuracy is shaped by distance, reflectivity, scan geometry and how multiple scans are registered together.

2. How Accuracy Changes With Distance in Real Projects

Even though the S150 and S350 list the same ranging accuracy, their 3D LiDAR scanning performance changes as distance increases. This is due to beam divergence, angular error, environment and surface reflectivity.

Typical real-world behaviour:

0–10 m: extremely precise, often sub-millimetre
10–25 m: excellent for engineering work, only slight noise increase
25–50 m: more noticeable noise and increasing angular error
50–100 m: atmospheric distortion and reduced overlap become evident
Near maximum range: still useful for mapping conveyors, yards and structures, but not suitable for tight fabrication tolerances

This distance-based behaviour is one of the most important truths to understand about 3D LiDAR scanning in field conditions.

3. Ranging Accuracy vs Positional Accuracy vs Global Accuracy

Anyone planning a project involving 3D LiDAR scanning must distinguish between:

Ranging Accuracy

The ±1 mm value — only the distance measurement.

3D Positional Accuracy

The true X/Y/Z location of a point relative to the scanner.

Global Point Cloud Accuracy

How accurate the entire dataset is after registration.

Global accuracy is the number engineers depend on, and it is normally around ±3–6 mm for large industrial sites — completely normal for terrestrial 3D LiDAR scanning.

4. What Real Field Testing Reveals About FARO S-Series Accuracy

Independent practitioners across mining, infrastructure, CHPPs, plants and structural environments report similar results when validating 3D LiDAR scanning against survey control:

±2–3 mm accuracy in compact plant rooms
±5–10 mm across large facilities
Greater drift across long, open, feature-poor areas

These outcomes are not equipment faults — they are the natural result of how 3D LiDAR scanning behaves in open, uncontrolled outdoor environments.

5. Why Registration Matters More Than the Scanner Model

Most real-world error in 3D LiDAR scanning comes from registration, not the laser itself.

Cloud-to-Cloud Registration

Good for dense areas, less reliable for long straight conveyors, open yards or tanks.

Target-Based Registration

Essential for high-precision engineering work.
Allows tie-in to survey control and dramatically improves global accuracy.

If your project needs ±2–3 mm globally, target control is mandatory in all 3D LiDAR scanning workflows.

6. Surface Reflectivity and Environmental Effects

Reflectivity dramatically affects measurement quality during 3D LiDAR scanning:

Matte steel and concrete return excellent data
Rusted surfaces return good data
Dark rubber, black plastics and wet surfaces reduce accuracy
Stainless steel and glass behave unpredictably

Environmental factors — wind, heat shimmer, dust, rain — also reduce accuracy. Early morning or late afternoon typically produce better 3D LiDAR scanning results on mining and industrial sites.

7. When ±1 mm Is Actually Achievable

True ±1 mm accuracy in 3D LiDAR scanning is realistic when:

Working within 10–15 m
Surfaces are matte and reflective
Registration uses targets
Tripod stability is high
Conditions are controlled

This makes it suitable for:

Pump rooms
Valve skids
Structural baseplates
Reverse engineering
Small mechanical upgrades

But achieving ±1 mm across a full plant, CHPP, or yard is outside the capability of any terrestrial 3D LiDAR scanning workflow.

8. S150 vs S350: Which One for Your Accuracy Needs?

S150 – Engineering-Focused Precision

Ideal for industrial rooms, skids, structural steel and retrofit design work where short-to-mid-range accuracy is essential.

S350 – Large-Area Coverage

Perfect for conveyors, rail lines, yards, and outdoor infrastructure.
Global accuracy must be survey-controlled for tight tolerances.

Both scanners deliver excellent 3D LiDAR scanning performance, but the S150 is the engineering favourite while the S350 is the large-site specialist.

9. What to Specify in Contracts to Avoid Misunderstandings

Instead of stating:

“Scanner accuracy ±1 mm.”

Specify:

Local accuracy requirement (e.g., ±2 mm at 15 m)
Global accuracy requirement (e.g., ±5 mm total dataset)
Registration method (mandatory target control)
Environmental constraints
Verification method (e.g., independent survey checks)

This ensures everyone understands what 3D LiDAR scanning will realistically deliver.

10. When a Terrestrial Scanner Is Not Enough

Do not rely solely on 3D LiDAR scanning for:

Machine alignment <1 mm
Bearing or gearbox placement
Certified dimensional inspection
Metrology-level tolerances

In these cases, supplement scanning with:

Laser trackers
Total stations
Metrology arms
Hybrid workflows

Conclusion: The Real Truth About 3D LiDAR Scanning Accuracy

FARO’s S150 and S350 are outstanding tools for industrial 3D LiDAR scanning, but the ±1 mm spec does not tell the full story. Real-world accuracy is a combination of:

Distance
Registration method
Surface reflectivity
Site conditions
Workflow discipline

When used correctly, these scanners consistently deliver high-quality, engineering-grade point clouds suitable for clash detection, retrofit design, fabrication planning and as-built documentation.

3D LiDAR scanning is not just a laser — it is an entire measurement system.
And when the system is applied with care, it produces reliable, repeatable data that reduces rework, improves safety, and strengthens decision-making across mining, construction, fabrication and industrial operations.

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
