Bunney’s Inc. delivers safe, precise potholing, also called utility daylighting for construction, utility, and infrastructure projects across Arizona. Using hydro excavation and vacuum excavation, our crews expose buried utilities with minimal surface impact, helping you avoid strikes, maintain schedules, and meet code requirements.

Why Contractors and Agencies Choose Bunney’s
- Safety-first execution – Procedures aligned with our S.H.A.R.P. values. See our safety program.
- Advanced equipment – Hydro and air/vac systems sized for Arizona soils and high-heat conditions.
- Experienced crews – Utility locating support and tight coordination with site supervisors.
- Documentation & QA – Depth measurements, photos, and notes to support as-builts and SUE efforts (QL-A exposures).
- Schedule reliability – Rapid mobilization and efficient daily production rates.
What Is Potholing?
Potholing is a non-destructive digging method that creates small test holes to verify the exact location and depth of underground utilities, gas, water, electric, telecom, fiber, and more before mass excavation.
Common Techniques
- Hydro Excavation: High-pressure water loosens soil; a vacuum removes spoil for a clean, controlled exposure.
- Air/Vac Excavation: Compressed air dislodges dry soils; ideal where moisture sensitivity or rapid backfill reuse is preferred.
- Hand Exposure (as needed): Used selectively near fragile assets or in tight access.
When Potholing Makes the Difference
- Pre-excavation verification along trench routes or structure footings
- Horizontal Directional Drilling (HDD) conflict checks and bore path confirmations
- Pipeline and conduit installations near congested corridors
- Roadway and streetscape work with dense utility networks
- Facility upgrades inside plants, campuses, and commercial sites
Our Process
- Scope & Utility Review – One-call ticket coordination (as applicable), utility maps, and site constraints.
- Method Selection – Hydro vs. air/vac based on soil, access, and sensitivity.
- Safe Exposure – Soft-dig potholes to reveal assets; protect with mats/shoring as needed.
- Measure & Document – Record utility depth, offset, and condition; capture photos for as-builts.
- Backfill & Restore – Controlled backfill and site cleanup; cold patch or temporary surface restoration where required.
- Turnover – Provide documentation and coordinate with your field team, engineer, or owner.

Arizona-Specific Considerations
- Soils & climate: Caliche and compacted desert soils may require higher-pressure hydro nozzles; heat management protects equipment and crews.
- Regulatory alignment: We follow local authority requirements and utility-owner standards; many agencies require potholing for conflict checks.
- Risk reduction: Dense urban corridors and fast-growing suburbs increase the need for utility verification to prevent costly strikes and project delays.
Safety & Compliance
- Pre-task plans, utility maps, and site-specific hazard reviews
- Protective systems, traffic control, and hot-work coordination where applicable
- Utility owner communication and careful exposure near high-risk assets
- Daily equipment checks and leak/pressure controls
Deliverables You Receive
- Utility exposure photos with identifiers
- Depth and offset measurements for design/as-built records
- Notes on utility material/condition (where visible)
- Location references (stationing, grid, or GPS if in scope)
