Auger Boring / Jack & Bore in Broomfield, CO
Auger boring in Broomfield for gravity sewer and gas crossings under US-36 and NW Parkway — cased pushes through Broomfield County expansive clay.
Auger Boring / Jack & Bore in Broomfield, Colorado
Auger boring in Broomfield drives steel casing for gravity sewer, gas carrier, and drainage conduit under US-36, NW Parkway, and Broomfield Creek outfall structures. Broomfield County expansive clay on most grids requires careful advance rate management to prevent casing binding in shrink-swell zones. NW Parkway lowland alluvial fill presents different soil conditions than the clay-dominant residential grids.
CDOT US-36 and NW Parkway authority templates specify bore-and-jack for active utility crossings — engineered submittal, casing diameter, and annular grouting specs scoped upfront. US-36 BRT corridor restrictions may add construction window requirements beyond standard CDOT permits.
Interlocken campus subsurface may contain compacted structural fill over native clay — vacuum pothole grid recommended before casing enters unfamiliar fill.

How Auger Boring / Jack & Bore Works in Broomfield
Broomfield auger boring starts with CDOT, NW Parkway authority, or city ROW confirmation and 811 clear. Expansive clay advance rate management standard. NW Parkway and US-36 BRT corridor work carries construction window requirements. Grade laser-set before launch pit opens.
Soil & Geology — Broomfield County
Broomfield County expansive clay, alluvial fill on NW Parkway lowlands, and compacted structural fill on Interlocken campus redevelopments.
Broomfield bores hit expansive clay on most residential grids, alluvial fill on NW Parkway lowlands, and structural fill over native clay on Interlocken campus redevelopments. County-border jobs may shift soil model mid-alignment.
Weather & Scheduling
US-36 corridor hail and winter chinook cycles push Broomfield crews to plan lightning holds on Interlocken campus pads and clay heave on Anthem residential grids.
US-36 corridor exposed sites see summer lightning and hail. Winter freeze-thaw on clay affects pit access in Anthem and Wildgrass. We plan seasonal windows with your campus or residential schedule.
811 Locates & Permits in Broomfield
City and County of Broomfield Public Works, CDOT US-36 and NW Parkway relocations, Broomfield Creek and Standley Lake watershed adjacency.
City and County of Broomfield handles all permits as a unified city-county. CDOT controls US-36 and NW Parkway state corridor bores. Standley Lake watershed may add review on west alignments. Interlocken campus coordination required for security and utility access.
Trenchless vs Open-Cut Here
US-36 and NW Parkway cutting is a non-starter for active utility crossings under both CDOT and parkway authority templates — bore-and-jack required. Open-cut fits off-highway Broomfield grids where grade tolerance and staging room allow.
Casing size, drive length, pit depth, groundwater, rail or highway flagging, and welding inspection.
How we work
Our Process for Broomfield Auger Boring / Jack & Bore
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.
