Substation earthworks in progress

Earthworks & Site Development

Site development contractor: mass grading, earthworks & substation site preparation.

From earthworks and site grading to drainage infrastructure and equipment foundations, we deliver the critical civil infrastructure that utility-scale substations, Battery Energy Storage Systems (BESS), and energy projects depend on.

01 - Site Preparation & Grading

The groundwork behind every successful project.

Precision grading and site development create the foundation for everything that follows.

Our crews self-perform clearing, grubbing, stripping, cut-and-fill operations, mass earthworks, and final grading with a commitment to quality, production, and meeting specification.

Using GPS machine control and survey-driven layouts, we establish the grades, elevations, and working surfaces required to support construction with confidence. From greenfield developments to complex facility expansions, our teams deliver construction-ready sites built to specification.

Capabilities

  • Site clearing, grubbing, and stripping
  • Mass excavation and cut-and-fill operations
  • Rough and finish grading
  • GPS machine control and survey support
  • Survey-driven layout and grade control
  • Structural fill placement and compaction
  • Construction laydown and staging areas
  • Erosion and sediment control
  • Access road and subgrade preparation

02 - Drainage & Stormwater Management

DRAINAGE INFRASTRUCTURE

Effective stormwater management begins with properly installed drainage infrastructure.

From culverts and drainage channels to large creek crossings, corrugated metal pipe systems, and engineered concrete headwalls, our crews build the infrastructure required to safely convey water, reduce erosion, and support long-term site performance. Whether supporting site development, maintaining drainage patterns, or managing stormwater across complex project sites, every system is constructed with a focus on quality, durability, and meeting specification.

Capabilities

  • Stormwater management infrastructure
  • Storm Water Retention System
  • Culvert installation
  • Detention / Retention Ponds
  • Concrete headwalls
  • Drainage channels and swales
  • Erosion control measures

03 - Foundations & Structural Support

THE FOUNDATION FOR EVERYTHING ABOVE.

The accuracy of any foundation starts with the work below it. Layout, excavation, subgrade preparation, elevation control, and compaction all play a direct role in how equipment, structures, and infrastructure are installed above.

Our crews support equipment foundations, concrete pads, structural foundations, and pile-supported systems across a range of civil and energy infrastructure projects. Where required, we coordinate helical pile, driven pile, and drilled foundation systems as part of the overall site development scope.

Working from survey control and engineered drawings, we focus on accurate placement, elevation control, and installation verification to help maintain schedule, quality, and construction continuity.
