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

Auger Boring / Jack & Bore in Fort Collins, CO
Jack and bore casing under Fort Collins rail spurs and I-25 north highway approaches — straight pushes when steel carrier protection is required in Poudre River alluvium and Larimer County clay.
Auger Boring / Jack & Bore in Fort Collins, Colorado
Auger boring in Fort Collins fits railroad agreements, storm outfall approaches under Poudre River levees, and straight alignments beneath building footprints where steerable HDD is unnecessary but casing is mandatory. Drive and reception pits are shored for Larimer County clay and cobble; casing segments jack on line and grade while spoil exits mechanically.
Union Pacific and BNSF windows along the railyards south of Old Town and Poudre River crossings 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, seasonal high-water handling, and flagging holds that can exceed jack duration.
Horizontal directional drilling in Fort Collins handles curves and long HDPE pulls; auger bore wins when the engineer draws a straight casing run under an I-25 approach slab or rail embankment near Timnath. We align method with your plan set before quoting — not after the rig arrives.

Local Auger Boring / Jack & Bore Scenarios
Real Larimer County angles — not generic statewide copy.
Storm outfall under a Poudre River levee toe
Straight RCP push under embankment fill where open cut would breach slope stability. Groundwater handling is scoped with floodplain review.
Casing under a College Avenue approach slab
Short rigid carrier protection under commercial hardscape where HDD profile tolerance is tighter than jack-and-bore grade control on a 65-foot push.
Multi-duct bundle inside casing on I-25 north 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 Fort Collins
Auger bore in Fort Collins starts with pit layout on survey line — locates cleared, shoring designed for clay sidewalls, and dewatering if Poudre River 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 — Larimer County
Larimer County clay, sandstone, and Poudre River alluvium — cobble and bedrock appear toward foothill approaches west of CSU.
Fort Collins bores encounter clay on the east side, Poudre alluvium near the river corridor, and sandstone or cobble toward foothill approaches. Campus and Old Town jobs may hit compacted urban fill over native clay. River-adjacent pulls need groundwater-aware ream staging.
Weather & Scheduling
Northern Front Range snow, chinook warm spells, and CSU game-day traffic push Fort Collins crews to plan winter pit protection and Collegian-area access windows.
Winter snow and freeze affect pit access and clay stiffness — spring runoff along the Poudre can raise groundwater. CSU event traffic influences staging on campus-adjacent jobs. We plan seasonal windows with your schedule.
811 Locates & Permits in Fort Collins
City of Fort Collins Engineering, Larimer County ROW, CDOT I-25 north relocations, and Poudre River floodplain rules on many paths.
City of Fort Collins Engineering handles street and ROW permits; Larimer County rules apply in Timnath-border and unincorporated pockets. CDOT I-25 north widening generates state relocations. Poudre River work may need floodplain review. CSU projects add owner coordination on access and inspection.
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 active railroad ROW is rarely permitted compared to cased bore templates.

How we work
Our Process for Fort Collins 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 Fort Collins — FAQ
Jack and bore or HDD for my Fort Collins 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 Fort Collins?
Physical jacking may finish in days; railroad agreements and inspection holds often drive weeks-to-months lead. Quote includes flagging scope.
What soils stall auger bore in Larimer County?
Running cobble and river alluvium without dewatering can stall progress. Test pits and geotech reduce mid-job surprises in variable fill near the Poudre.
Can auger bore install sewer in Fort Collins?
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 Fort Collins?
Yes — pit excavation exposes adjacent utilities. Valid locates and potholing at conflicts are mandatory before pits open, identical to HDD jobs.
