3D Laser Scanning New Caledonia | Hamilton By Design
Engineering projects in New Caledonia operate in a unique environment. Nickel processing plants, port facilities, power stations and infrastructure are often decades old, heavily modified and located far from design offices. Accurate site information is the difference between a smooth project and an expensive lesson.
3D laser scanning has become the most reliable way to capture existing conditions across Nouméa, Koné and the remote mine sites of the Grande Terre. Instead of relying on tape measures and assumptions, LiDAR technology records millions of precise measurements to create a true digital twin of the asset.
The Challenge of Brownfields Projects in New Caledonia
Many facilities in New Caledonia share the same constraints:
Limited shutdown windows
Corrosive coastal environments
Historical modifications with poor drawings
Logistics that make repeat site visits costly
Multi-discipline coordination between local and overseas teams
Traditional survey methods struggle to capture congested pipe racks, structural steel distortions or equipment that has shifted over time. When drawings do not match reality, fabrication delays and site rework quickly follow.
The Scan Is the Backbone of the Project
The initial scan quality sets the tone for every task that follows. The point cloud becomes the backbone of the project—design, detailing, fabrication and construction all rely on it.
If you start with a broken backbone, you will have problems everywhere else:
Simple tasks become difficult
Measurements are questioned
models need rework
fabricators lose confidence
schedules start to slip
A clean, well-registered scan makes coordination easy. A poor scan multiplies effort for every member of the team.
Protecting the Whole Project Team
3D laser scanning is not just about creating a model—it is about protecting everyone involved:
Project managers who must control time and cost
Engineers responsible for safe and compliant designs
Designers and draftspersons who need reliable geometry
Fabricators who must build components that fit
Construction crews who install the work on short shutdowns
When the as-built data is right, the entire chain works with confidence. When it is wrong, every discipline inherits the problem.
How 3D Laser Scanning Changes the Outcome
A terrestrial laser scanner captures a complete point cloud of the site in hours rather than weeks. The data can then be used for:
Accurate as-built models for upgrades and expansions
Tie-in design for new conveyors, tanks and platforms
Structural verification of aging infrastructure
Clash detection before fabrication
Shutdown planning and risk reduction
Asset documentation for long-term maintenance
For New Caledonian projects, the biggest benefit is capture once, design anywhere. Local scanning crews can collect the data while engineering teams in Australia or New Zealand work from the same digital environment without further travel.
Typical Applications Across New Caledonia
Mining & Processing
Nickel plant upgrades
Conveyor replacements
Chute and transfer redesign
Tank and thickener modifications
Access platforms and walkways
Ports & Infrastructure
Wharf structural assessments
Ship loader interfaces
Pipe bridges and services
Electrical and control building upgrades
Energy & Utilities
Power station retrofits
Water treatment facilities
Fuel storage terminals
From Point Cloud to Deliverables
A professional workflow generally includes:
On-site LiDAR capture with survey control
Registration and quality assurance
Creation of usable formats for Revit, AutoCAD, SolidWorks or Navisworks
Extraction of models, drawings or clash reports
Ongoing support during fabrication and installation
The result is engineering data you can trust—without the need for multiple trips to site.
Ready to De-Risk Your Project?
Whether your project is in Nouméa, Koné or a remote mine site, 3D laser scanning provides the foundation for safe, predictable and efficient engineering. Get the backbone right at the start and the rest of the project becomes easier.
Refineries, Heritage Buildings & Industrial Retrofits Done Right
The Inner West of Sydney is home to some of the city’s most complex refurbishment environments. From legacy refinery and industrial sites through to heritage-listed warehouses, factories, and commercial buildings, these assets were never designed with modern codes, loading requirements, or services in mind.
Yet today, they’re being asked to support:
New plant and equipment
Adaptive re-use and change of occupancy
Heavier floor loads
Updated fire, seismic, and structural standards
Modern services routing in very old structures
This is where many refurbishment projects run into trouble — not because the design is poor, but because the starting information is wrong or incomplete.
The Inner West Problem: Old Buildings, New Standards
Much of the Inner West’s industrial and heritage building stock was constructed:
Under superseded Australian Standards
With unknown material properties
Using construction methods no longer permitted
With undocumented modifications over decades of use
What often looks acceptable visually may be:
Structurally marginal under modern load cases
Locally compromised due to corrosion, settlement, or fatigue
Modified in ways that no longer match original drawings
When these issues are discovered late in the design process, the outcome is almost always the same:
Redesign
Strengthening
Programme delays
Budget escalation
Why Waiting Until “Detailed Design” Is Too Late
A common scenario we see in Inner West refurbishments:
Concept design proceeds based on legacy drawings or assumptions
Floor layouts, equipment, and architectural intent are developed
Engineering review begins
Structural checks identify:
Inadequate floor capacity
Unsupported penetrations
Changed load paths
Degraded or altered members
Design is forced to change — often significantly
At this point, the engineer isn’t blocking creativity — they’re responding to reality.
The issue isn’t engineering input. The issue is when the true condition of the structure becomes visible.
Start With a Scan: Let Designers Create With Confidence
Engineering-grade 3D laser scanning at the very beginning of a refurbishment changes the entire dynamic of a project.
Instead of reacting to unknowns later, the project team starts with:
Verified geometry
True floor levels and deflection
Structural alignment and deformation
Accurate column, beam, and slab positions
Measured deviations from original drawings
This gives architects and designers something powerful:
Freedom to design within known constraints — not guessed ones.
Heritage & Industrial Retrofits: Why Scanning Matters Even More
Heritage Buildings
Heritage structures often prohibit invasive investigation early on. 3D scanning allows:
Non-intrusive verification of geometry
Identification of movement or deformation
Assessment of tolerance drift over time
Planning of sympathetic strengthening solutions
Refineries & Legacy Industrial Sites
Inner West refinery and process facilities bring additional challenges:
Tight access
Live plant interfaces
Safety-critical environments
Brownfield congestion
Scanning provides:
Safe remote measurement
Clash-free retrofit design
Confidence before shutdowns
Reduced rework during construction
When Standards Change, Reality Matters
One of the most common late-stage surprises in refurbishments is floor capacity.
Buildings that performed adequately for decades may no longer comply with:
Current live load requirements
Change-of-use provisions
Equipment point loads
Modern safety factors
Without accurate structural geometry and context, engineers are forced to:
Assume worst-case scenarios
Over-design strengthening
Restrict layouts unnecessarily
Early scanning supports informed engineering judgement, often resulting in:
Targeted strengthening instead of blanket solutions
Retention of original fabric where possible
Reduced material and construction costs
From Point Cloud to Engineering Decisions
At Hamilton By Design, scanning is not a standalone service — it’s an engineering tool.
Our process typically supports:
Structural verification of existing buildings
Floor flatness, level, and deflection assessment
Alignment checks of columns and frames
Scan-to-CAD models for design integration
Fit-for-purpose information for refurbishment decisions
This is especially critical in Inner West projects, where:
Every millimetre matters
Access is limited
Heritage considerations are real
Late changes are costly
Design With Knowledge, Not Surprises
Refurbishments don’t fail because buildings are old. They fail because assumptions survive too long.
By starting with an engineering-led scan:
Designers get space to create
Engineers get data they can trust
Asset owners avoid late-stage shocks
Projects move forward with confidence
If you’re planning a refinery upgrade, heritage refurbishment, or adaptive re-use project in Inner West Sydney, the smartest decision you can make is to scan first — before concept becomes constraint.
Thinking about a refurbishment or retrofit in the Inner West?
Engineering-grade 3D scanning at the start gives your project clarity, confidence, and creative freedom — not limitations.
AS 1100 & LiDAR Scanning: Compliant Engineering Drawings from Point Clouds
If you’ve ever tried to update old plant drawings, verify a brownfield tie-in, or issue “as-built” documentation after a shutdown, you’ll know the pain: the site never matches the drawings, access is limited, and the smallest dimensional miss can cascade into rework, clashes, and schedule blowouts.
That’s where engineering-grade LiDAR scanning and AS 1100 (the Australian Standard for technical drawing) make a powerful combination. LiDAR gives you truth data (reality capture), and AS 1100 gives you a shared language for turning that truth into clear, consistent, contract-ready documentation.
AS 1100 standardises the way we communicate engineering information through drawings: layout, line types, projection methods, dimensioning rules, tolerancing conventions, symbols, notes, and drawing presentation.
In practice, AS 1100 helps you answer questions like:
Which edges are visible vs hidden? (line conventions)
How are views arranged and interpreted? (projection and view layout)
How do we dimension so the fabricator can’t misread it? (dimensioning rules)
How do we document what matters vs what’s “reference only”? (notes and drawing hierarchy)
How do we keep drawing sets consistent across multiple contributors? (formatting + standards)
That consistency is exactly what’s needed after a scan—because point clouds are rich, but they’re not automatically “communicable” in the way a compliant drawing set is.
What LiDAR scanning adds that drawings alone can’t
A LiDAR scanner captures millions (often billions) of spatial points that represent real surfaces—steel, concrete, pipe, equipment, structure—creating a point cloud that can be registered into a unified coordinate system.
In the engineering context, the big advantages are:
Speed: capture complex geometry quickly, often with minimal disruption
Coverage: see what’s hard to measure with tape/total station (overhead services, congested pipe racks, odd geometry)
Context: capture “everything,” not just what someone remembered to measure
Traceability: you can always “go back” to the scan for verification and queries
Clash prevention: scan-to-CAD makes it far easier to design upgrades that actually fit
But here’s the key: a point cloud isn’t a deliverable most trades can fabricate from directly. That’s why AS 1100 becomes the bridge between capture and construction.
The combined workflow: Point cloud → model → AS 1100 drawings
1) Capture the site as it really is
We scan the area of interest and register scans into a coordinated dataset. This becomes the base truth for everything that follows. If the project is shutdown-driven, we plan scanning around access windows and risk controls (often capturing adjacent tie-in zones too, because “nearby” services are where surprises live).
2) Establish intent: “What are we delivering?”
Not every project needs the same output. Typical outcomes include:
As-built drawings for existing assets
As-found models to support new design work
Dimensional verification for fit-up and prefabrication
Digital QA against design intent (scan-vs-model comparison)
3) Convert scan data into engineering geometry (as much as needed)
Sometimes the best output is a controlled 3D model (plant layout, pipe spools, structural members). Other times the project is best served by 2D drawings extracted from a model.
We’ll typically create:
key datums and grids
primary steel / structure
equipment envelopes and critical interfaces
piping runs and connection points (where relevant)
floor levels, platforms, access constraints, clearance zones
4) Document to AS 1100 so the drawing set is unambiguous
This is where AS 1100 shines. We turn geometry into drawings that read cleanly and consistently across teams.
drawing borders, title blocks, revision control, and drawing register discipline
In short: LiDAR gives accuracy, AS 1100 gives clarity.
Where AS 1100 + LiDAR scanning delivers immediate value
Brownfield upgrades and tie-ins
Tie-ins fail when the “as-built” condition is wrong. A scan gives you real geometry; AS 1100 drawings package it so designers, fabricators, and installers share the same reference. This is especially useful when multiple contractors are interfacing.
Fabrication and spool accuracy
If you’re fabricating offsite (pipe spools, platform steel, handrail sections, ducting), you need dependable dimensions and an agreed drawing language. Scan-derived models support accuracy; AS 1100 drawings support fabrication interpretation and QA sign-off.
Shutdown planning and constructability
A point cloud is a brilliant planning tool—access routes, crane clearances, removal paths, temporary works, and “what’s in the way.” But shutdown packages still need compliant drawings for permits, isolations, install workpacks, and handover packs. AS 1100 keeps those packages readable and defensible.
Verification and “what changed?”
Sites evolve. A scan provides a timestamped snapshot. Drawings updated to AS 1100 become the controlled record: what was there, what was installed, and what the current state is. That matters for maintenance, safety, and future projects.
Practical example: Turning a congested pipe rack into a buildable upgrade
Imagine you’re adding a new line through an existing pipe rack:
Scan the rack to capture all existing services, supports, cable trays, and steel
Model critical geometry (existing plus proposed) to check routing and supports
Clash check before fabrication begins
Issue AS 1100 drawings for:
support details
spool isometrics (if applicable)
arrangement drawings showing tie-in locations
sections through congestion zones
installation notes and tolerances where appropriate
Verify post-install with a follow-up scan if required for QA/closeout
That’s the “work together” part: the scan stops guesswork, and AS 1100 stops misinterpretation.
Common mistakes when scanning isn’t tied back to AS 1100
Delivering point clouds without a drawing strategy (stakeholders can’t use them effectively)
Over-modelling everything (time is spent modelling non-critical items instead of delivering useful documentation)
Unclear dimensioning (scan accuracy is wasted if dimensions are presented ambiguously)
No controlled datums (people argue about “where zero is” and models drift between disciplines)
Weak revision control (the drawing set becomes untrustworthy fast)
A standards-led drawing approach prevents most of these.
How we approach it at Hamilton By Design
Our angle is simple: engineering-led scanning—not scanning for its own sake.
We capture reality with LiDAR.
We translate it into the level of model detail the project actually needs.
We document outputs with the discipline and consistency expected in Australian engineering environments.
Closing thought: accuracy is only valuable if it’s understandable
LiDAR scanning can deliver millimetre-grade spatial truth. But in real projects, truth still has to travel through people—engineers, drafters, fabricators, installers, supervisors, and asset owners.
AS 1100 makes that truth readable. LiDAR makes it reliable.
Together, they turn messy real-world geometry into clear, controlled documentation that supports safer installs, faster shutdowns, and fewer surprises.
Accurate site data is the difference between a smooth upgrade and a shutdown full of surprises. At Hamilton By Design, we provide engineering-grade 3D laser scanning (LiDAR) across the Central Coast NSW — including Wyong, Gosford, Tuggerah and Somersby — and convert that data into design-ready CAD and 3D models for industrial and building projects.
If you’re planning equipment upgrades, new conveyors, structural modifications or fabrication packages, scanning gives you reliable geometry before steel is cut or contractors mobilise.
Who this service is for
Our Central Coast scanning services are typically used by:
Project engineers planning plant or building upgrades
Maintenance teams preparing shutdown scopes
Fabricators needing accurate tie-in dimensions
Asset owners updating as-built records
Consultants managing brownfield modifications
If drawings don’t match reality — or don’t exist at all — scanning becomes the safest and fastest way to establish an accurate baseline.
From scan to CAD: turning site data into buildable designs
A point cloud on its own doesn’t solve project risk. What matters is converting scan data into usable engineering outputs.
Our workflow supports:
2D CAD drawings (plans, sections, elevations)
3D CAD models for layout and clash detection
Tie-in modelling for new equipment and structures
Verification of clearances and access zones
Fabrication-ready geometry for workshop drawings
This scan-to-CAD process is especially valuable for retrofit projects where new components must integrate with existing assets.
Why 3D scanning is ideal for brownfield upgrades
Most Central Coast industrial and commercial sites are brownfield environments — tight access, legacy equipment and undocumented modifications.
3D laser scanning helps to:
Reduce site re-visits and manual re-measuring
Identify clashes early in the design phase
Support off-site prefabrication
Shorten shutdown windows
Improve safety by limiting exposure time on site
When combined with engineering design, scanning becomes a risk-reduction tool, not just a survey method.
Where Central Coast workshops are producing components for remote sites.
Local coverage: Wyong, Gosford, Tuggerah and Somersby
Being based on the Central Coast means we can support:
Rapid site capture
Staged scanning across multiple areas
Follow-up verification scans as scope evolves
That flexibility is important when designs change during live projects or shutdown preparation.
How accurate is engineering-grade LiDAR scanning?
Accuracy depends on site conditions and scope, but scanning provides consistent, repeatable geometry across complex environments that would be difficult and time-consuming to measure manually.
More importantly, it captures:
Spatial relationships
Real clearances
True equipment alignment
which are critical for retrofit engineering and fabrication.
When is scanning worth the investment?
Scanning typically delivers the best value when:
Drawings are outdated or incomplete
Fabrication must fit first time
Shutdown time is expensive
Access is restricted or unsafe
Multiple trades must coordinate in tight spaces
In many projects, preventing one major clash or rework cycle pays for the scan many times over.
Planning an upgrade or fabrication project on the Central Coast?
If you’re preparing for a shutdown, equipment upgrade or fabrication package across the Central Coast, early scanning can significantly reduce downstream risk.

Wall Crack Monitoring & Structural Movement Baseline Scans | NSW
Know When Cracks Are Cosmetic — and When They’re Not
Cracks in walls are common, but not all cracks are harmless. The real risk isn’t just that a crack exists — it’s how fast it’s changing. Without a baseline, there’s no reliable way to tell whether your property is stable or slowly moving toward serious structural damage.
That’s where our Property Wall Movement Baseline Scan comes in.
What Is a Baseline Scan?
A baseline scan is a high‑accuracy digital survey of your property taken at the moment cracking is first observed. Using precision scanning technology, we capture:
Wall alignment and deflection
Crack location, length, and width
Floor and ceiling reference planes
Structural reference points across the building
This scan becomes your time‑zero reference point — a measurable snapshot of your building’s condition today.
Why a Baseline Matters
Without a baseline:
Cracks are judged visually (subjective and unreliable)
Engineers lack historical movement data
Insurance claims become harder to substantiate
Small issues can quietly become major repairs
With a baseline:
Movement can be quantified in millimetres
Crack growth rates can be tracked over time
Engineers can make confident, data‑driven decisions
You gain early warning before damage becomes critical
How the Process Works
1. Initial Scan
We perform a non‑invasive scan of affected areas and key structural zones to establish your baseline condition.
2. Data Archiving
All scan data is securely stored and referenced to fixed control points within your property.
3. Follow‑Up Scans
Repeat scans (3, 6, or 12 months later) are compared against the baseline to calculate:
Crack propagation rate
Wall movement direction
Structural settlement or heave
4. Clear Reporting
You receive a clear, easy‑to‑understand report showing:
Measured movement (if any)
Rate of change over time
Professional recommendations
Ideal For
Homeowners noticing new or worsening cracks
Properties affected by reactive soils or subsidence
Buildings near excavation or construction activity
Insurance documentation and dispute resolution
Engineers requiring long‑term movement data
Early Data Saves Money
Monitoring movement early often means minor intervention instead of major reconstruction. A baseline scan gives you certainty, evidence, and peace of mind.
If nothing is moving — you’ll know. If something is — you’ll know before it’s too late.
Book a Baseline Scan
If you’ve noticed cracking, now is the right time to act.
