Chain of Custody, Data Governance, and Engineering-Grade LiDAR Workflows
Why Chain of Custody Matters in Reality Capture
As LiDAR scanning technology becomes more widely used across mining, manufacturing, and infrastructure, the role of scan data is changing.
Point clouds are no longer just visual references — they are increasingly relied upon for:
- Engineering design decisions
- Asset verification
- Contractor coordination
- Insurance and compliance
- Legal and dispute resolution
In this environment, the question is no longer “Do you have a scan?”
It is:
“Can this data be trusted?”
The Problem with Traditional Scanning Workflows
Many scanning providers still operate with a simple delivery model:
- Capture data
- Process it
- Export a file
- Send via Dropbox or USB
At that point:
- File versions are uncontrolled
- Edits are not tracked
- Data integrity cannot be verified
- There is no audit trail
For engineering, this creates risk.
For legal or contractual matters, it can make the data unusable.
What is Chain of Custody in LiDAR Scanning?
Chain of custody refers to the complete, traceable record of how data is handled, from capture through to final use.
For LiDAR scanning, this includes:
- Who captured the data
- When and where it was captured
- Equipment used and calibration status
- Processing steps and software workflows
- File versions and revisions
- Who has accessed or modified the data
A properly managed chain of custody ensures that:
- Data is authentic
- Data is unchanged or changes are recorded
- Data can be defended if challenged
Introducing Data Governance Through the 3DEXPERIENCE Platform
At Hamilton By Design, LiDAR scanning is not treated as a standalone service.
It is integrated into a controlled engineering environment using the 3DEXPERIENCE platform.
This shifts the workflow from:
- File-based delivery
to - Managed digital asset lifecycle
How LiDAR and 3DEXPERIENCE Work Together
1. Controlled Data Capture
- Engineering-led scanning methodologies
- Defined scan plans and coverage
- Documented site conditions and limitations
2. Structured Data Processing
- Registered point clouds with documented workflows
- Export formats aligned to downstream engineering use
- Verification of alignment and accuracy
3. Centralised Data Storage
- All scan data stored in a secure, managed environment
- No reliance on uncontrolled file sharing
- Single source of truth for all stakeholders
4. Revision Control and Traceability
- Every model, drawing, and dataset is version-controlled
- Changes are tracked and attributable
- Previous revisions remain accessible
5. Multi-User Collaboration
- Engineers, designers, and contractors access the same dataset
- No duplication of files
- Reduced risk of working on outdated information
6. Audit-Ready Data
- Full history of data handling and modification
- Clear documentation of methodology
- Suitable for compliance, contractual, and legal review
Engineering Outcomes, Not Just Scan Data
The integration of LiDAR with the 3DEXPERIENCE platform enables a shift from raw data delivery to engineering-ready outputs:
- Point clouds linked directly to CAD models
- Scan-to-SolidWorks workflows for fabrication
- Drawings developed within a controlled revision environment
- Digital twins that evolve with the asset
This ensures that the data is not only accurate — it is usable and maintainable over time.
Reducing Risk Across the Asset Lifecycle
By combining chain of custody principles with structured data governance, Hamilton By Design helps clients:
- Reduce rework during construction and shutdowns
- Improve confidence in design decisions
- Maintain accurate as-built records
- Support compliance and audit requirements
- Provide defensible data where disputes arise
The Future of Reality Capture
As industries move toward digital twins and data-driven decision-making, unmanaged scan files will become increasingly inadequate.
The future is:
- Controlled
- Traceable
- Collaborative
- Defensible
Summary
LiDAR scanning provides the data.
Chain of custody ensures it can be trusted.
Data governance ensures it remains valuable.
Hamilton By Design delivers all three — combining engineering-led reality capture with structured digital environments to support the full asset lifecycle.
