Trunk sewer under Colfax mixed-use fill
Deep gravity sewer with tight elevation tolerance — shaft footprints replace a continuous trench that would conflict with shallow Xcel and fiber.

Tunneling / TBM in Lakewood, CO
Microtunneling and pipe jacking for Lakewood municipal trunk sewers — sealed-face mining when HDD diameter or grade tolerance cannot meet Jefferson County gravity specs along Bear Creek.
Tunneling / TBM in Lakewood, Colorado
Tunneling and TBM work in Lakewood targets municipal trunk sewers, large outfalls, and owner specs where steerable HDD cannot hold gravity grade or diameter. Shaft spreads localize disruption compared to open trenching a deep urban trunk through utility-congested fill along Colfax and Wadsworth.
Bear Creek and Green Mountain outfall projects often land here — high groundwater, floodplain review, and settlement limits push engineers toward pipe jacking instead of wide open cuts through mixed-use blocks and riparian ROW.
Residential laterals and short commercial shots stay on HDD or auger bore. Microtunneling in Lakewood is a municipal and large-contractor tool — we scope shafts, slurry handling, and Jefferson County inspection milestones when your plans call for it.

Local Tunneling / TBM Scenarios
Real Jefferson County angles — not generic statewide copy.
Large outfall toward Bear Creek
Floodplain and bank stability rules favor bored installation over stripping riparian ROW. Shaft design accounts for seasonal high water and C-470 adjacency.
Deep collector near Belmar commercial district
Retail districts combine shallow telecom, chilled water, and gas with deep sanitary collectors. TBM reduces surface disruption across customer-access drives.
CDOT large-span alternative on C-470 corridor
When HDD profile cannot meet large RCP grade on a state crossing, microtunneling may be specified — shafts, spoils export, and MOT are engineered upfront.
How Tunneling / TBM Works in Lakewood
Lakewood TBM and microtunnel scopes begin with shaft design, geotech, and permit path — City of Lakewood, Jefferson County, CDOT, and Bear Creek floodplain where applicable. Laser-guided line and grade drives the mining face; slurry or spoil handling is planned for urban sites with limited laydown near Belmar. Inspection hold points follow municipal or owner spec before carriers are accepted.
Soil & Geology — Jefferson County
Jefferson County expansive clay, Bear Creek alluvium, and decomposed granite toward Green Mountain — urban fill on redeveloped Colfax parcels.
Lakewood bores hit expansive clay on most residential grids, Bear Creek alluvium near the greenbelt, and granite cobble toward Green Mountain. Redeveloped Colfax parcels may hide structural fill over native clay. River-adjacent pulls need groundwater-aware ream staging.
Weather & Scheduling
Foothill hail and chinook winds push Lakewood crews to plan lightning holds on west-side pads and clay shrink-swell along Bear Creek.
Spring runoff along Bear Creek raises groundwater on south-side jobs. Summer hail affects exposed west-side pads. We plan seasonal windows with your restoration and tenant schedules.
811 Locates & Permits in Lakewood
City of Lakewood Community Development, Jefferson County ROW, CDOT US-6 and C-470 relocations, Bear Creek floodplain on south alignments.
City of Lakewood handles street and driveway permits; Jefferson County ROW applies on edges near Golden and unincorporated pockets. CDOT controls US-6 and C-470 state bores. Bear Creek floodplain work may need additional review. HOA rules in newer west-side infill affect restoration specs.
Trenchless vs Open-Cut Here
Open trenching a deep trunk through Colfax corridor or Bear Creek ROW destroys more surface infrastructure than shaft-and-drive tunneling. HDD still wins on shallow laterals; TBM applies when diameter, grade, or length exceed practical steerable limits.

How we work
Our Process for Lakewood Tunneling / TBM
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
Tunneling / TBM in Lakewood — FAQ
When does Lakewood need TBM instead of HDD?
Large-diameter gravity sewer, tight grade tolerance, or owner spec for sealed-face mining. We review your engineer's method note and geotech before quoting.
How long do Lakewood microtunnel projects take?
Shaft construction and permitting often exceed mining duration. Bear Creek floodplain and C-470 adjacency add calendar weeks — scoped in the estimate.
Can microtunneling work in Lakewood expansive clay?
Yes with proper shaft shoring and face support. Groundwater along Bear Creek may require dewatering — geotech drives the shaft design.
Is TBM overkill for a Lakewood residential lateral?
Usually yes — laterals and short commercial runs stay on HDD or auger bore. TBM applies to trunk lines and large outfalls per engineer spec.
Who permits microtunnel shafts in Lakewood?
City of Lakewood and Jefferson County depending on location and floodplain. CDOT adds scope on C-470-adjacent work — permit path is scoped upfront.
