What Drives the Cost of Underground Utility Work
No made-up prices here. Instead: the factors that move a number up or down, so you can compare bids on equal terms.

Eight things that move the price.
Length and depth
More feet and more depth mean more soil, more pipe and more backfill. Deeper trenches also need protection.
Pipe or conduit size
Larger pipe needs wider trenches, heavier machines and often structures such as manholes and thrust blocks.
Rock
Shallow limestone slows trenching and can call for hammering, ripping or a different route.
Water and weather
Groundwater and wet weather slow digging, hauling and compaction and may call for pumps or stone.
Boring or trenching
Boring usually costs more per foot but can avoid cutting drives, roads and landscaping.
Haul-off and fill
Soil that cannot stay on site has to go somewhere, and fill or stone may have to come in.
Permits and fees
Taps, meters, right-of-way permits, engineering and inspections are real costs, often outside the dig itself.
Restoration
Sod, concrete, asphalt and landscaping can equal the cost of the dig on finished properties.
A ballpark, never a quote.
Ranges below are editable placeholders for planning, not our prices.
Compare scopes, not just totals.
Ask every bidder to price the same job. List what each includes: locates, permits, trench depth, bedding, compaction, haul-off and restoration. Ask what each assumes about rock and water, and how extra work is priced and approved.
A bid that is far below the others may simply leave things out. A good bid says what it includes, what it assumes and what it excludes.
