Civil Services
Full-scope civil services for underground electrical infrastructure — open trenching, micro tunnelling, and directional boring for cable installation, from site preparation and excavation to cable laying, backfill, and surface reinstatement for utilities, developers, and infrastructure projects.
Micro Tunnelling
Trenchless installation of conduit sleeves and casings beneath roads, railways, and existing infrastructure where open-cut excavation isn't viable — driven from jacking and reception pits.
- Microtunnelling (MTBM) for sleeved conduits
- Auger boring and pipe ramming
- Pipe jacking for carrier pipes and casings
- Minimal-disruption crossings under roads, rail & services
Directional Boring (HDD)
Horizontal directional drilling for the installation of underground cables and conduits along curved or extended routes with minimal surface disruption.
- Pilot bore, reaming and pull-back operations
- Steerable bores for road, creek and easement crossings
- Conduit and cable pull-through in a single pass
- Small and large diameter bore capability
Trench Excavation & Earthworks
Controlled open-cut trenching for underground cable routes, including potholing, benching, and shoring to safely install LV, HV, and streetlighting cables.
- Open-cut trenching to specified depths and widths
- Rock breaking and bulk excavation
- Trench shoring and benching for safe entry
- Dewatering and groundwater management
Underground Cable Laying
Careful placement, bedding, and protection of cables within the trench, including sand bedding, warning tape, and mechanical protection.
- LV, HV, and pilot cable installation
- Sand bedding and surround
- Warning tape and marker installation
- Conduit and mechanical protection
Backfill & Compaction
Layered backfill and compaction to engineered specifications, ensuring trench integrity and preventing subsidence or surface failure.
- Selective backfill and compaction in layers
- Density testing to specification
- Imported fill supply and placement
- Subsidence prevention and quality control
Surface Reinstatement
Full reinstatement of disturbed surfaces — bitumen, concrete, paving, and turf — to match or exceed the original condition.
- Bitumen and asphalt reinstatement
- Concrete footpath and kerb restoration
- Paving and turf reinstatement
- Traffic management during works
Compliance & QA Documentation
Full as-laid records, survey data, and QA documentation delivered to meet DNSP, council, and project requirements.
- As-laid drawings and GPS records
- Compaction and density test reports
- DBYD and permit compliance
- Inspection and handover documentation
Traffic Management & Safety
Certified traffic management, site safety, and environmental controls to keep worksites safe and compliant throughout the project.
- Certified traffic control plans
- Site-specific WHS and environmental controls
- Spill prevention and sediment control
- Utility safe-work practices
Underground Cable Installation — Done Right
From the first cut to final reinstatement, our civil crews deliver safe, compliant open trenching for underground cable projects of any size.
