Commercial Excavation & Site Development in Spokane

Commercial projects require more than moving dirt. They require precision, coordination, and long-term performance.

Avey Excavation provides commercial excavation and site development services in Spokane, WA, supporting multifamily, townhome, retail, and industrial construction across the Inland Northwest.

Featured Projects

Major Multi-Family Development | 5 Mile Prairie (Spokane, WA)

  • The Scope: Full-scale site development and high-capacity stormwater management.

  • The Execution: Successfully managed the installation of the region’s largest StormTech MC-3500 subsurface detention system. Our crews executed all primary city utility tie-ins—sewer, domestic water, and stormwater—completing taps and backfills with surgical efficiency to keep the project on its critical path.

  • Result: A fully stabilized, utility-ready site delivered on schedule.

Urban Residential Complex
| The Cora Project (Spokane, WA)

  • The Scope: High-intensity site mobilization, hazardous material mitigation, and structural foundation preparation.

  • The Execution: Currently managing the complex process of excavating and hauling hazardous materials off-site to clear the way for multiple building footprints. Our team is providing the structural pads and underground plumbing rough-ins essential for the project's vertical launch.

  • Impact: Ensuring a clean, compliant start for one of the region's newest multi-family developments.

Waterfront Civil Work
| Kaniksu Marina (Priest Lake, ID)

  • The Scope: Specialized shoreline excavation and marina dock infrastructure within environmentally sensitive zones.

  • The Execution: Removed aging marina systems and prepared the shoreline for modern, high-end dock foundations. This project required strict adherence to North Idaho’s environmental regulations, balancing heavy machinery work with delicate shoreline preservation.

  • Result: Successfully modernized waterfront infrastructure while protecting the local ecosystem.

Why Professionals Partner
with Avey Excavation

  • Schedule Stewardship: We recognize our role as the first domino. When excavation falls behind, every trade behind it feels the impact. We work aggressively to hit our milestones so framing and concrete crews can mobilize on schedule.

  • Commercial-Scale Equipment & Capacity: From large-volume earthwork to deep utility installations, we have the fleet and hauling capacity to handle serious commercial scope. Our operators understand the structural importance behind every cut and every trench.

  • Local Regulatory Authority: We’ve spent years working within the specific building codes, inspection processes, and soil conditions of Spokane and Kootenai Counties. We understand the red tape and how to navigate it efficiently.

  • Clear, Detailed Bidding: We review civil plans carefully and look for potential site hurdles early. Our goal is to provide transparent proposals that reduce change orders and eliminate surprises once work begins.

Safety & Professional Standards

Commercial work demands accountability.

  • OSHA-compliant operations
