Description
Potholing in Tempe by DEVCO Development and Engineering
DEVCO Development and Engineering provides precise potholing (utility daylighting) in Tempe and across Maricopa County for contractors, industrial facilities, and public agencies. We expose buried utilities using non-destructive methods so you can build, trench, or bore with real-world information instead of guesswork. Our crews measure and document actual utility locations, clearances, and conditions in the field.
What Our Potholing Service Involves
Potholing is the process of safely digging small, targeted holes to uncover existing underground utilities. We typically use vacuum excavation and hand tools to expose gas, water, sewer, electrical, communications, and industrial process lines.
Once exposed, we record depth, horizontal offset, pipe size, and material. That verified data goes back to your engineer or superintendent so designs, bore paths, and trench lines can be adjusted before heavy excavation starts.
Where Potholing Fits into Tempe Projects
Potholing Tempe projects usually comes up in tight corridors, older industrial areas, and around active plants where as-builts don’t tell the whole story. Anytime you’re crossing or running parallel to unknown utilities, potholing is the smart first step.
We do a lot of potholing for industrial facilities Tempe wide, including manufacturing sites, logistics yards, campuses, and specialty processing plants. These locations often have private lines stacked on top of city utilities—steam, reclaimed water, chemical lines, fiber, and power all sharing the same space.
Typical Uses for Utility Potholing
- Verifying depth and alignment before horizontal directional drilling (HDD) or jack-and-bore work
- Checking conflicts for new fire lines, water services, and sewer laterals
- Confirming clearances before installing large foundations, tanks, or equipment pads
- Supporting design surveys for new site utilities and plant expansions
- Validating as-builts during due diligence or pre-design investigations
How We Perform Potholing Safely and Efficiently
On each job, we start by reviewing your plans, markings, and scope so we’re opening the right locations. We coordinate with utility locators, set up traffic and pedestrian control if we’re in streets or parking lots, then bring in our vacuum excavation equipment.
We cut a small surface opening, use air or water pressure to break up the soil, and vacuum it out until the utility is fully visible. Where your engineer needs larger test pits—say to see multiple lines together or inspect bedding—we may supplement with compact equipment like a mini excavator on open, clear ground, always keeping safety and utility tolerances in mind.
After measurements and photos are taken, we backfill, compact, and restore the surface per project requirements.
What You Should Know Before Starting
A few things help your potholing run smoothly:
Have any existing plans or as-builts ready, identify priority crossings, and let us know about plant safety rules or access limits. In congested industrial facilities, we also like to walk the route with your maintenance or utilities lead so we understand live operations and critical lines.
Common Questions About Potholing
How many potholes do I need?
It depends on risk. High-pressure gas, major electrical feeders, or complex plant manifolds usually justify more test holes. For smaller private services in open ground, we can often confirm a run with fewer, well-placed potholes.
What does potholing cost?
Pricing is driven by access, surface type (asphalt, concrete, landscaping), depth, soil conditions, traffic control needs, and documentation requirements. For planning purposes, you can review typical cost ranges with our online potholing cost calculator, then call us to talk through your specific scope.
Why Contractors Choose DEVCO
We work in underground utilities every day, but we also understand plant operations and construction schedules. Our team is experienced around live facilities, coordinating with shutdowns, permits, and confined work windows instead of slowing your project down.
DEVCO Development and Engineering is a DVBE (Disabled Veteran Business Enterprise), SDVOSB, PDBE, SB-Micro, and SB-PW firm. Those designations reflect our track record and can also help meet participation goals on public and private projects.
