Why Chain of Custody Matters in 3D LiDAR Scanning and Engineering Data

In today’s engineering environment, capturing data is no longer enough — proving the integrity of that data is what matters most.

As 3D LiDAR scanning becomes standard across mining, manufacturing, and infrastructure projects, a new question is emerging:

👉 Can your scan data stand up in a dispute, audit, or court of law?

This is where Chain of Custody and Data Governance come into play.

What is Chain of Custody in Engineering Data?

Chain of custody is the documented record of how data is captured, handled, transferred, and stored over time.

It creates a traceable, auditable history of your data — from the moment it is scanned through to final design, modelling, and decision-making.

Without it, even the most accurate LiDAR scan can be questioned.

Why This Matters for LiDAR Scanning

In engineering and construction environments:

• Scan data is used for design decisions
• It informs modifications and upgrades
• It can be referenced in claims, disputes, and compliance reviews

If there is no verified chain of custody:

• Data can be challenged
• Accuracy can be disputed
• Liability can shift

A broken chain means the data may not be considered reliable — regardless of how good the scan looks.

---

The Shift from “Point Clouds” to “Trusted Data”

Traditionally, scanning providers focused on delivering:

• E57 files
• RCP / RCS datasets
• Meshes or visual outputs

But the industry is moving beyond that.

The real value is now:

✔ Who captured the data
✔ When it was captured
✔ How it was processed
✔ Who accessed or modified it
✔ What version is being used

This is data governance, not just data delivery.

Where Engineering-Led Scanning Changes the Game

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

It is part of an engineering workflow, where:

• Data is captured with design intent in mind
• Processing aligns with CAD and modelling requirements
• Outputs are structured for FEA, drafting, and fabrication
• Governance is maintained from scan to final deliverable

This approach ensures the data is not just usable —
it is defensible.

Digital Chain of Custody + 3DEXPERIENCE

Modern platforms like Dassault’s 3DEXPERIENCE enable:

• Controlled access to models and drawings
• Revision tracking (IFR / IFA / IFC)
• Centralised data storage
• Full audit trails

This creates a digital chain of custody, where every interaction with the data is recorded and traceable.

The result:

➡ Confidence in decisions
➡ Reduced risk
➡ Stronger legal standing

Why It Matters Now More Than Ever

With increasing legal scrutiny and data-driven decision making:

• Engineers need verified inputs
• Clients need accountability
• Projects need traceability

Chain of custody is no longer optional —
it is becoming a requirement.

Final Thought

Anyone can deliver a scan.

But not everyone can deliver data you can trust, defend, and build from.

That’s the difference between
scanning providers and engineering-led reality capture.

What Engineers, Clients & Fabricators in Sydney Actually Want Today

There was a time when opening a 3D model on an iPad felt revolutionary.

For many engineers and fabricators in Sydney, eDrawings was one of the first tools that made this possible—taking complex CAD models and turning them into something portable, visual, and easy to share.

At the time, it wasn’t just useful—it was inspirational.

It changed how people thought about:

• Reviewing designs
• Communicating with clients
• Visualising fabrication before it happened

But more importantly, it laid the groundwork for something much bigger.

Why eDrawings Was So Important

eDrawings solved a very real problem:

👉 How do you share engineering data with people who don’t have CAD?

Instead of sending:

• Heavy CAD files
• Static PDFs
• Confusing drawings

You could send a lightweight file that allowed users to:

• Rotate models
• Zoom into details
• Measure geometry
• Understand assemblies visually

For engineers and fabricators, this was a major shift.

Early Influence on Design Review & Coordination

Tools like eDrawings didn’t just improve communication—they influenced the development of more advanced platforms.

Software such as Autodesk Navisworks expanded on this idea by allowing teams to:

• Combine multiple models
• Review them in real time
• Detect clashes
• Simulate construction sequencing (4D)

This marked the transition from:

❌ Viewing models
➡️
✅ Managing entire project environments

In many ways, eDrawings helped pave the path toward this kind of integrated thinking.

What Sydney Engineers & Fabricators Want Today

Fast forward to today—and expectations have changed dramatically.

Across Sydney’s construction, infrastructure, and industrial sectors, engineers, clients, and fabricators are now looking for:

1. Live Access to Models (Not Files)

The old workflow:

• Email a file
• Download it
• Open it locally

The new expectation:

👉 Access models instantly, from anywhere

2. Real-Time Collaboration

Teams now expect to:

• Review models together
• Add comments and markups
• Share feedback instantly

Not after the fact—but during the process.

3. Single Source of Truth

One of the biggest problems in Sydney projects is:

• Multiple versions of drawings
• Conflicting information
• Outdated files on site

Clients now want:

👉 One central, controlled model

4. Cross-Platform Access

Fabricators, engineers, and site teams all use different tools.

They need:

• A system that works across devices
• Compatibility with multiple CAD formats
• Easy access without specialist software

5. Reduced Risk on Site

Ultimately, everything comes back to:

👉 Does it reduce risk?

Better model access means:

• Fewer errors
• Better coordination
• Improved installation outcomes

The Shift: From eDrawings to 3DEXPERIENCE

This is where the industry has moved.

eDrawings was:

• File-based
• Local
• Static (even if interactive)

Today, that functionality has evolved into:

👉 3DEXPERIENCE platform

What the 3DEXPERIENCE Platform Actually Is

The 3DEXPERIENCE platform is not just a viewer.

It is a cloud-based engineering environment that connects:

• CAD models
• Project data
• Teams and stakeholders

All in one place.

It provides a real-time, collaborative ecosystem where people, data, and tools are connected across the entire project lifecycle

Instead of sending files, teams now:

👉 Work on the same model—at the same time

---

From Viewer to Platform

The key difference is simple:

eDrawings	3DEXPERIENCE
File-based	Cloud-based
Individual viewing	Team collaboration
Static sharing	Live data access
Limited workflow	Full project integration

The 3DEXPERIENCE viewer alone allows:

• Real-time navigation
• Annotation
• Model comparison
• Cross-platform access

But that’s just the entry point.

5 Key Services the 3DEXPERIENCE Platform Offers

Here are the five most important capabilities for engineers and fabricators in Sydney:

1. Cloud Data Management (Single Source of Truth)

All CAD data is stored centrally in the cloud.

This allows:

• Version control
• Secure access
• Elimination of duplicate files

No more emailing drawings or wondering which version is correct.

2. Real-Time Collaboration & Markup

Teams can:

• View models in a browser
• Add comments and markups
• Share feedback instantly

No downloads required.

This is a major evolution from eDrawings-style file sharing.

3. Product Lifecycle Management (PLM)

The platform manages:

• Design changes
• Revisions
• Approval workflows
• Project tracking

It supports the full lifecycle of a project from concept to fabrication and beyond

4. Simulation & Engineering Analysis

Integrated tools allow:

• Structural analysis
• Performance simulation
• Design validation

This ensures models are not just visually correct—but engineering validated.

5. Manufacturing & Fabrication Integration

The platform supports:

• Manufacturing workflows
• Toolpath generation
• Digital fabrication planning

This connects design directly to production, improving efficiency and reducing errors
