Trunk under Perkins utility fill
Deep gravity — shafts avoid OG&E trench.

Tunneling / TBM in Stillwater, OK
Microtunneling for Stillwater municipal trunks — pipe jacking when HDD cannot hold gravity grade on US-177 interceptors.
Tunneling / TBM in Stillwater, Oklahoma
Tunneling in Stillwater targets deep gravity sewer and storm lines where HDD cannot meet tolerance on US-177 interceptors. Rental-scale laterals stay on HDD.
Shafts beat open trench through dense Perkins utility fill.

Shored shafts on contract holds. Laser mining; pipe jacks. Inspection per municipal contract.
Soil & Geology — Payne County
Payne County red clay and sandy loam with Garber sandstone west — shrink-swell heaves older lateral PVC under rental-housing berms and campus-area hardscape.
Stillwater bores encounter shrink-swell red clay with sandy loam and Garber sandstone lenses toward the west. Rental-housing berms and campus hardscape mean restoration cost drives method choice when pavers and parking cannot be sacrificed. Low areas near Stillwater Lake and local drainage add brief groundwater rise after spring storms.
Weather & Scheduling
North-central tornado exposure with Payne County red-clay wet-dry cycles — spring rain softens campus-adjacent ROW; gameday and graduation weekends tighten MOT on Washington and Perkins.
Gameday and graduation weekends affect MOT on Washington and Perkins — we plan bore windows around known campus events when possible. Spring thunderstorms soften clay; summer heat affects long US-177 pulls. We communicate when weather or event calendars should shift bore dates.
811 Locates & Permits in Stillwater
City of Stillwater Engineering, Payne County ROW, ODOT on US-177 corridor, OSU facilities coordination on select campus-adjacent routes.
City of Stillwater permits street cuts and drive work inside limits. Payne County ROW on rural US-177 approaches. ODOT controls state highway bores on US-177. Routes near OSU facilities may need university or owner coordination beyond standard city permit — identified during scope, not assumed on every quote.
Trenchless vs Open-Cut Here
Open trunk through commercial fill hits utilities. Shafts localize.

How we work
Our Process for Stillwater Tunneling / TBM
Scope & Site Walk
You share plans or describe the problem; we confirm alignment, depth, access, and which trenchless method fits Oklahoma soils.
811 Ticket & Marks
Oklahoma One-Call ticket filed; two business days minimum before pits open unless your permit path differs. We pothole where marks conflict.
Profile & Permits
Bore plan, ODOT or city ROW permits, railroad agreements, and crossing engineering when the path leaves private property.
Rig Mobilization
Compact spread for tight Edmond lots; larger HDD for I-35 or I-40 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 sand lenses.
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.
