Union Pacific casing under a Globeville industrial spur
Railroad template requires steel casing with internal carrier and grouting. Drive pit shoring and flagging windows set the calendar — not the jack footage alone.

Auger Boring / Jack & Bore in Denver, CO
Jack and bore casing under Denver rail spurs and CDOT highway approaches — straight pushes when Union Pacific templates and CDOT specs require steel carrier protection in Front Range clay.
Auger Boring / Jack & Bore in Denver, Colorado
Auger boring in Denver fits railroad agreements, storm outfall approaches, and straight alignments under building footprints where a steerable path is unnecessary but casing is mandatory. Drive and reception pits are shored for Denver County expansive clay; casing segments jack on line and grade while spoil is removed mechanically.
Union Pacific and BNSF windows along the Globeville industrial belt and South Platte levees often specify jack and bore with welded casing inspection — HDD may be ruled out by template or owner spec. Directional Boring Colorado scopes pit dewatering, groundwater handling, and flagging holds that can exceed the jack duration.
Horizontal directional drilling in Denver handles curves and long HDPE pulls; auger bore wins when the engineer draws a straight casing run under a highway approach slab or rail embankment. We align method with your plan set before quoting — not after the rig is on site.
Denver projects
Local Auger Boring / Jack & Bore Scenarios
Real Denver County angles — not generic statewide copy.
Storm outfall under a South Platte levee toe
Straight RCP push under embankment fill where open cut would breach slope stability. Groundwater handling and dewatering are scoped with floodplain review.
Casing under a Colfax approach slab
Short rigid carrier protection under mixed-use hardscape where HDD profile tolerance is tighter than jack-and-bore grade control allows on a 60-foot push.
Multi-duct bundle inside casing on I-70 frontage
CDOT detail calls for shared casing with dividers for future telecom and electric — auger bore sets the shell; internal pulls follow inspection milestones.
How Auger Boring / Jack & Bore Works in Denver
Auger bore in Denver starts with pit layout on survey line — locates cleared, shoring designed for clay sidewalls, and dewatering if groundwater enters the drive pit. Casing segments advance with a rotating head; welding inspection and railroad flagging follow owner templates. Reception pit exposes the face for carrier install and grout per agency detail.
Soil & Geology — Denver County
Denver County expansive clay, decomposed granite, and alluvial fill dominate most residential corridors — shallow utilities and South Platte adjacency complicate open trenching.
Most Denver bores encounter expansive clay with intermittent sand lenses and seasonal groundwater rise along the South Platte corridor. Shallow groundwater raises buoyancy risk on long HDPE pulls — we size ream stages and pullback plans accordingly. Foothill-adjacent shots toward Green Valley Ranch add decomposed granite cobble that slows penetration without the right bit and mud program. We do not assume a single soil model for all of Denver County; your quote reflects entry/exit geotech when you have it.
Weather & Scheduling
Front Range hail, spring snow, and summer afternoon storms push Denver crews to plan mud programs, lightning holds, and schedule buffers around severe weather.
Spring snow and hail are calendar risks in Denver. Saturated clay softens ROW and can delay entry pit work for days. Summer heat above 95°F affects crew safety and drilling fluid performance on long pulls. We plan around known wet seasons and communicate when a bore should wait for drier conditions rather than risk a frac-out toward the South Platte.
811 Locates & Permits in Denver
City and County of Denver Community Planning & Development, CDOT District 1, South Platte floodplain, and UP/BNSF rail agreements apply on many bore paths.
Inside Denver city limits, street cuts, driveway removals, and floodplain work may need CPD permits and stormwater compliance. CDOT District 1 controls state highway bores on I-25, I-70, and I-76 — expect traffic control plans and sometimes night-only drilling windows. Railroad crossings require separate agreements with Union Pacific or BNSF. HOA communities in Central Park and Lowry may require landscape restoration bonds — trenchless reduces but does not eliminate those conversations.
Trenchless vs Open-Cut Here
Jack and bore keeps rail and highway pavement width intact on short straight obstacles. Curved HDPE sewer pulls without casing usually shift to HDD. Open-cut across a Union Pacific ROW is rarely permitted compared to cased bore templates.

How we work
Our Process for Denver 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.
FAQ
Auger Boring / Jack & Bore in Denver — FAQ
Jack and bore or HDD for my Denver project?
Casing templates and straight alignments favor auger bore. Curved paths or long HDPE without casing favor HDD. We review your engineer's method note before quoting.
How long do railroad auger bores take in Denver?
Physical jacking may finish in days; Union Pacific or BNSF agreements and inspection holds often drive weeks-to-months lead. Quote includes flagging scope.
What soils stall auger bore in Denver County?
Running sand and cobble without dewatering can stall progress. Test pits and geotech reduce mid-job surprises in variable fill near the South Platte.
Can auger bore install sewer in Denver?
Yes — when plans specify casing and gravity grade on a straight push. Microtunneling may apply on large trunk lines with tighter tolerance.
Do auger bores need Colorado 811 in Denver?
Yes — pit excavation exposes adjacent utilities. Valid locates and potholing at conflicts are mandatory before pits open, identical to HDD jobs.
