Potholing Xcel gas before Arapahoe Road bore pit
Paint conflicts in retail corridor — air-vac confirms depth before bore crew stages.

River, Highway & Railroad Crossings in Centennial, CO
Vacuum excavation in Centennial — potholing Xcel, South Arapahoe Water, and carrier fiber before HDD rigs open pits on Arapahoe Road and E-470 corridor.
River, Highway & Railroad Crossings in Centennial, Colorado
Vacuum excavation in Centennial pothole-exposes Xcel gas and electric lines, South Arapahoe Water mains, carrier fiber, and irrigation before HDD and auger boring rigs approach pit locations. Dense residential grids in Willow Creek and Piney Creek carry utility stacking common to 1980s–2000s Arapahoe County subdivision development.
Expansive clay responds well to air-vacuum in dry conditions; Dry Creek alluvium near the tributary may require hydro. South Arapahoe Water main conflicts in the Arapahoe Road corridor get confirmed by vacuum pothole before any rod enters ground.
E-470 corridor jobs may require CDOT and E-470 authority coordination before vacuum excavation near active embankments.

Real Arapahoe County angles — not generic statewide copy.
Pre-bore pothole grid on Willow Creek residential lot
Dense utility stack — air-vac confirms depth and separation before HDD crew opens pit.
Dry Creek alluvium pothole for alignment engineer
Hydro-vac near tributary — utility depth confirmed before bore profile finalized.
E-470 embankment corridor pothole
E-470 authority coordination confirmed — air-vac exposes utility before CDOT bore alignment is finalized.
How River, Highway & Railroad Crossings Works in Centennial
Centennial vacuum crews arrive with 811-cleared marks. Air-vac for expansive clay; hydro for Dry Creek alluvium. E-470 corridor work carries authority coordination. Depth logs documented for engineers.
Soil & Geology — Arapahoe County
Arapahoe County expansive clay, sandy alluvium near Dry Creek and Cherry Creek, and compacted fill on E-470 corridor developments.
Centennial bores hit expansive clay on most residential grids, sandy alluvium near Dry Creek, and compacted E-470 corridor fill over native clay. South-metro clay behavior differs from north metro — shrink-swell cycles affect mud weight and pit shoring on summer jobs.
Weather & Scheduling
Eastern Arapahoe plains hail and summer heat push Centennial crews to plan lightning holds on exposed south-metro retail pads.
Summer heat and afternoon lightning affect exposed south-metro retail pads. Dry Creek spring runoff raises groundwater on south alignments. We communicate seasonal windows with your project schedule.
811 Locates & Permits in Centennial
City of Centennial Public Works, Arapahoe County ROW, CDOT I-25 south and E-470 relocations, Dry Creek floodplain adjacency.
City of Centennial handles permits inside city limits; Arapahoe County ROW applies on outer edges. CDOT I-25 and E-470 authority control state corridor bores. Dry Creek floodplain adjacency may add review on south alignments.
Trenchless vs Open-Cut Here
Potholing with vacuum protects Xcel gas and South Arapahoe Water mains in dense residential grids — hand-probe in expansive clay near 30-year-old infrastructure carries settlement and damage risk.

How we work
Our Process for Centennial River, Highway & Railroad Crossings
Scope & Site Walk
You share plans or describe the problem; we confirm alignment, depth, access, and which trenchless method fits Colorado soils.
811 Ticket & Marks
Colorado 811 ticket filed; wait period before pits open unless your permit path differs. We pothole where marks conflict.
Profile & Permits
Bore plan, CDOT or city ROW permits, railroad agreements, and crossing engineering when the path leaves private property.
Rig Mobilization
Compact spread for tight Boulder lots; larger HDD for I-25 or I-70 relocations — matched to length and diameter.
Pilot & Ream
Steered pilot on design line, ream passes sized for your pipe or casing, fluid program tuned for clay or sandstone.
Pullback & Install
HDPE fusion, steel casing, or multi-duct bundle pulled with tension and bend-radius monitoring.
Test & As-Built
Pressure test, mandrel, or survey records for owners, inspectors, and operators as spec requires.
Restore & Closeout
Compact pits, replace sod or hardscape per scope, leave 811 ticket and locate map in your project file.
