Why Structural Steel Designers Are Using 3D Laser Scanning Before Mining Shutdowns
Structural steel modifications are common during mining shutdowns. Whether it is installing new access platforms, reinforcing structures, modifying conveyor supports, or integrating new plant equipment, steelwork upgrades must often be completed within extremely tight shutdown windows.
For structural steel designers and drafting teams, one of the biggest risks is that existing plant conditions may not match the original engineering drawings.
Over years of operation, most mining plants undergo continuous modifications. Equipment upgrades, maintenance repairs, and structural changes often result in facilities that differ significantly from the original design documentation.
When new steel structures are fabricated based on outdated drawings, installation problems can occur during shutdowns.
This is why many engineering teams now rely on 3D laser scanning to capture accurate plant geometry before structural steel design begins.

The Structural Steel Design Challenge in Existing Plants
Structural steel upgrades inside mining plants are rarely simple projects.
Designers must work within environments that include:
• Dense pipework systems
• Conveyor structures
• Mechanical equipment
• Electrical cable trays
• Existing steel platforms and supports
Even small dimensional inaccuracies can create installation challenges once fabricated steel arrives onsite.
Common shutdown issues include:
• Steel members clashing with existing equipment
• Incorrect connection locations
• Misaligned support structures
• Insufficient access clearances
When these problems are discovered during a shutdown, they often require onsite cutting, welding, or redesign work, which can delay project schedules.
How 3D Laser Scanning Improves Structural Steel Drafting
3D laser scanning captures millions of measurement points across an industrial facility, producing a highly accurate point cloud model of the plant.
This digital model allows engineers and drafting teams to design structural steel components directly within the true geometry of the existing facility.
Instead of relying on assumptions, designers can verify clearances and connections before fabrication begins.
Typical structural projects that benefit from scanning include:
• Conveyor support structures
• Access platforms and walkways
• Equipment support frames
• Structural reinforcements
• Maintenance access structures
By designing within an accurate digital environment, structural steel drafters can significantly reduce installation risks during shutdowns.
From Laser Scan to Structural Steel Models
Once scanning is completed, the point cloud data can be imported into engineering design software where it becomes the basis for scan-to-CAD modelling.
Structural designers can then:
• Model steel members around existing infrastructure
• Verify bolt connection locations
• Confirm equipment clearances
• Develop fabrication drawings with confidence
• Detect clashes before steel fabrication begins
This workflow dramatically improves coordination between engineers, drafters, fabricators, and shutdown installation teams.
Supporting Structural Steel Projects Across Mining Facilities
Across the mining industry, 3D scanning is increasingly used to support brownfield plant upgrades and shutdown engineering projects.
Structural engineers and drafting teams are using scanning to create more accurate designs and reduce installation uncertainty.
By combining laser scanning, point cloud modelling, and modern CAD tools, engineering teams can move from site capture to fabrication drawings much faster than traditional survey methods.
This approach reduces shutdown risk while improving project efficiency.
