The Bellevue Rail Cart Assembly Facility was delivered for the Government of Western Australia Public Transport Authority as part of the state’s expanding rail infrastructure program.

The facility required a high-performance industrial slab capable of accommodating heavy assembly loads, maintaining tight crack control, and delivering long-term durability with minimal maintenance.

To achieve these objectives, a Dramix Combi Slab solution was adopted — combining conventional mesh reinforcement with high-performance Dramix 4D steel fibres.

The Challenge

The project presented several critical design requirements:

• High load capacity for rail cart assembly operations
• Efficient slab design to optimize materials and construction program
• Controlled nominal crack widths across the entire facility
• Reduced long-term maintenance requirements
• Durable performance in a demanding industrial environment

Traditional mesh-only reinforcement was assessed but did not provide the same level of performance efficiency and crack control required for the asset lifecycle expectations of a government infrastructure project.

The Solution – Dramix Combi Slab

The adopted Combi Slab system incorporated:

• Conventional steel mesh reinforcement
• Dramix 4D high-performance steel fibres

This hybrid reinforcement approach delivers the reliability of mesh with the enhanced post-crack performance and multi-directional reinforcement of steel fibres throughout the concrete matrix.

Through careful engineering design and detailing, a nominal crack width was applied consistently across the facility — ensuring structural integrity, durability, and visual consistency.

Performance Outcomes

Superior Crack Control
Optimised Structural Efficiency
Enhanced Post-Crack Behavior
Reduced Maintenance Risk

Project Result

The Bellevue Rail Cart Assembly Facility now benefits from:

• A durable, high-performance industrial slab
• Improved constructability and installation efficiency
• Long-term asset resilience
• A technically robust and visually consistent floor system

The Dramix Combi Slab solution delivered a modern, engineered alternative to traditional reinforcement — aligning with the performance, durability, and lifecycle expectations of the Public Transport Authority.
