CIVIL INFRASTRUCTURE & ROADS

Underground utilities and road construction, done right the first time.

Precision civil work from the first cut to final backfill.

We work directly with project and geotechnical engineers, utility districts, and municipal inspectors across Gallatin, Park, and Madison counties. Our principal has spent over a decade building those relationships in the area. We don't show up as a name on a bid sheet. We show up as people who have worked alongside these teams before. We know the soils, the inspectors, and what it takes to build a product that stands its warranty.

Water Mains & Fire Suppression

We install civil infrastructure to include water distribution and transmission lines for subdivision buildouts, road corridor utilities, and municipal system extensions. Work is coordinated directly with utility districts and project engineers, from main line sizing and tie-in locations through pressure testing and final as-builts.

Fire suppression is included from the beginning. We stub hydrants laterals, set hydrant assemblies, and contractors install thrust blocks per fire district requirements, so suppression coverage is built into the main.

4" - 16" ductile iron and PVC
AWWA and fire district spec compliance
Pressure testing and disinfection per DEQ/district requirements
Coordination with civil engineers and Montana utility districts on alignment and tie-in sequencing

Sanitary Sewer Main

We install gravity sewer collection systems for subdivision buildouts, commercial developments, and municipal system extensions, self-performing all excavation, bedding, pipe lay, manhole installation and backfill. 3D Smart Grade control on our excavators means we hit invert elevations on the first pass, which keeps the work moving and avoids the re-bedding cycles that blow schedules.

Work is coordinated directly with the sewer district and project engineer from alignment review, through final inspection.

8" - 15" PVC gravity main (SDR 35 and SDR 26)
Precast manhole installation, bench forming, and frame setting
Laser and machine-control grade verification on all pipe runs
Low-pressure air testing and mandrel per district requirements
Coordination with sewer district on tie-in sequencing and inspection

Storm Drainage

We install storm drainage for subdivision roads, commercial sites, and highway corridor work - from simple culvert crossings to full underground collection systems with catch basins, storm main, and outlet structures. All excavation, bedding, pipe lay, and structure installation is self-performed by our crew.

We coordinate with civil engineers on invert elevations, outlet sizing, and tie-ins to existing systems, and stage our work to hand off a finished drainage system that paving and site crews can follow directly.

Precast catch basins and curb inlets set to finish grade
12"-36" storm main, including outlets and control structures
Detention basin grading and shaping to engineer design
Coordination with paving contractors on inlet and drain elevation sequencing

Road Construction & Right-of-Way

We build new roads and restore existing ones after utility work - self-performing all earthwork, subgrade prep, aggregate base, and drainage. For new road construction, we take the project from raw ground through finished subgrade and base course, ready for the paving crew to follow. For ROW and utility corridor work, we open the trench, install the utility, and restore the road to a condition that meets or exceeds what was there before.

We manage and oversee the paving, concrete, curb, and sidewalk as part of our scope, coordinating sequencing, overseeing install, and ensuring the subgrade delivers proper crowns and drainage.
