Scope of Work

Five disciplines, self-performed

Complete civil infrastructure for public and private projects — one contractor from deep utility excavation to final grade.

Wet and dry utility systems installed to grade, tested, and turned over right — from shallow service lines to deep mainline excavation.

  • Water main installation
  • Sanitary sewer
  • Storm drain
  • Fire water systems
  • Utility relocations
  • Deep utility excavation
  • Manholes
  • Catch basins

STA 02+00 — Site Development

Site development

Ground ready for vertical construction — commercial, residential, and industrial sites delivered on schedule and on grade.

  • Commercial site development
  • Residential development
  • Industrial sites
  • Building pads
  • Road preparation
  • Parking lots

STA 03+00 — Mass Excavation

Mass excavation

Production earthmoving with GPS machine control on site — balanced cuts, engineered fills, and haul cycles that keep the schedule honest.

  • Earthmoving
  • Cut & fill

STA 04+00 — Stormwater Systems

Stormwater systems

Detention, retention, and conveyance — engineered stormwater installed from excavation to final connection.

  • Box culverts
  • Utility vaults
  • Retention ponds
  • StormTech detention systems

STA 05+00 — Trucking

Trucking

Our own trucks on our own schedule — material moved when the project needs it, not when a broker can find it.

  • Import / export
  • Aggregate
  • Gravel
  • Sand
  • Structural fill
