Access Logistics & DIDO
Clarke Rd access corridor, Walpole district, South West WA — road-based heavy haulage; DIDO operations from Brunswick/Hazelmere hubsProject Logistics & B2B Overview
Geographic Location and Topography
The Clarke Rd Walpole quarry operates within the South West region of Western Australia, a zone characterized by high annual rainfall exceeding 1,100 mm. Dense karri and jarrah forest terrain creates significant haul road degradation risk during winter months. Intense precipitation events generate persistent mud accumulation on access corridors, demanding continuous road maintenance protocols, compacted gravel resurfacing, and strategic deployment of graders to sustain safe truck payload cycles without unacceptable axle loading on softened subgrades.
B2B Lifecycle and Operational Status
Currently classified as Operating, this construction materials quarry supplies aggregates, road base, and crushed rock to civil and infrastructure contractors across the South West. B&J Catalano Pty Ltd maintains dual operational hubs — Brunswick and Hazelmere — enabling responsive dispatch logistics. Continuous operations depend on:
- Diesel-intensive mobile plant fleets (excavators, loaders, rigid dump trucks)
- Reliable grid or substation-fed power for fixed crushing and screening circuits
- Coordinated DIDO workforce rotations from regional centres
Extraction Engineering and Infrastructure
Surface quarrying operations employ drill-and-blast or rip-and-load methodologies feeding primary jaw crushers. Downstream processing relies on multi-stage conveyor systems transferring crushed material through secondary and tertiary screening decks. Key infrastructure considerations include:
- Conveyor belt tensioning and alignment under high-humidity conditions
- Dust suppression systems integrated at transfer points
- Substation power distribution for 24/7 crusher motor loads
- Stockpile management for graded aggregate segregation
ESG, Value Chain and Sustainability
B&J Catalano faces growing ESG decarbonisation pressure across its quarry portfolio. The South West operational context presents viable pathways including:
- On-site solar PV arrays to offset diesel generator dependency for auxiliary loads
- Transition planning for electric or hybrid light vehicles within site perimeters
- Rehabilitation bonds and progressive land restoration aligned with WA DMP requirements
- Fuel consumption telemetry to benchmark and reduce Scope 1 emissions per tonne produced
