At Precision Hydro Excavations, we don’t just dig — we deliver complete end-to-end support for your jobsite. By pairing our NDD (Non-Destructive Digging) trucks with our small tipper unit, we ensure every excavation is completed, backfilled, and made safe — all in one visit.
Our tipper comes pre-loaded with:
- 20mm crushed rock for immediate reinstatement
- Conduits and service ID stickers showing asset type and depth
- A dedicated crew ready to support your project from start to finish
5 Key Benefits of Adding a Tipper Unit to Your NDD Booking
- No Open Trenches or Test Holes Left Overnight
Ensure a safe, compliant site before your crew leaves each day. - No Extra Labour Required for Backfilling
We handle the entire process — dig, install, and reinstate — reducing the need for extra site coordination. - Clear Service Marking for Future Works
Our conduits and asset identification stickers make it easy for surveyors or other contractors to locate services later. - Streamlined Workflow = Greater Productivity
While the NDD unit begins the next hole, the tipper backfills the last — saving time and minimising downtime. - Peace of Mind for Site Supervisors
No last-minute backfill materials, labour shortages, or safety concerns — it’s all handled.
Ideal For:
- Developers needing confirmed asset locations for planning – Quality Level A (QL-A)
- Architects / Designers look for asset design optimisation
- Clear no-go zone markers to ensure mechanical excavation doesn’t hit assets
- Surveyors establishing no-go zones
- Contractors conducting asset inspections and condition reports
What is Quality Level A (QL-A) Subsurface Utility Information?
Quality Level A (QL-A), as outlined in the Australian Standard AS5488, is the highest standard of subsurface utility information (SUI). It refers to the positively validated location and attributes of a subsurface utility in three dimensions.
- QL-A provides absolute spatial accuracy.
- Validation is typically performed via NDD/hydro excavation to expose the asset directly.
- It is required in areas where construction, design, or development is planned.
- Helps prevent costly damage to subsurface services during future works.
This level of utility information is critical for risk mitigation, design clarity, and establishing safe working zones — and we make it easier by providing a full package: digging, confirming, marking, and reinstating.
