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.
