Coffman Excavation

What Coffman Excavation does

Coffman Excavation is a privately held heavy civil construction contractor founded in 1979 by Carl Coffman and headquartered in Oregon City, Oregon. Operating under the legal entity Coffman Excavation LLC, the firm is licensed in Oregon, Washington, and Idaho, with 51-100 employees. It delivers ten core service lines — Site Preparation, Mass Excavation, Design Build, Street & Road Construction, Port Infrastructure, Utility Installation, Demolition, Emergency Response & Slide Repair, Environmental Remediation & Bank Stabilization, and Septic Systems — using its own workforce, union labor (IUOE and Laborers locals), and equipment fleet to general contractors, property owners/developers, healthcare and educational institutions, and government agencies.

The company's technical profile centers on executing logistically complex excavation and site development work in constrained urban and active-facility environments, including seismic upgrades under operating buildings (Oregon State Capitol CAMS III), mass excavations adjacent to operating hospitals (OHSU, Legacy Emanuel, Providence Willamette Falls), and aviation-grade infrastructure at the Port of Portland. Notable scale benchmarks include 400,000 cubic yards of earthwork at the new Sherwood High School, a 110-acre log pond rehabilitation moving 500,000 cubic yards of material, and a 350,000 SF data center greenfield for Flexential.

Coffman Excavation generates revenue through project-based, custom-quoted contracts awarded via competitive bidding and direct negotiation, with contract durations that can span multiple years. Its go-to-market is relationship-driven enterprise field sales into a diversified base of institutional clients, supported by a strong safety reputation (repeat AGC Safety Pride Awards, 2020 and 2022 AGC National Safety Excellence Awards finalist). The firm is privately held with no disclosed private equity or parent company, and its ownership reportedly includes both field and office employees.

• Kerr Contractors Oregon: Woodburn, OR-based heavy civil and highway contractor performing earthwork, grading, and roadway construction across Oregon. Direct peer to Coffman in PNW heavy civil and highway/site prep scope.
• Rotschy Inc. Vancouver, WA-based site preparation, excavation, and utility contractor serving the greater Portland and Southwest Washington market. Closely comparable to Coffman in PNW site prep and utility installation focus.
• Mike McGowan & Sons Construction: Clackamas, OR-based excavation, site preparation, and underground utilities contractor of similar size to Coffman, serving the Portland metro and greater PNW market.
• Wildish Standard Paving: Eugene, OR-based heavy civil and paving contractor performing earthwork, grading, and road construction throughout Oregon. Comparable PNW regional heavy civil competitor with similar project mix.

Broad incumbents

• Knife River Corporation: Large publicly traded aggregates and heavy civil construction company with significant Pacific Northwest operations. Competes with Coffman on road, site prep, and aggregate-heavy projects, but at much larger scale and broader service portfolio.
• Granite Construction: National heavy civil contractor with active Pacific Northwest operations in transportation, water resources, and site development. Overlaps Coffman on larger ODOT, Port of Portland, and large site prep scopes but at meaningfully larger scale.
• Kiewit Corporation: One of North America's largest heavy civil and infrastructure contractors, often competing with regional firms on large PNW infrastructure projects. Indirect competitor on mega-projects but not in Coffman's smaller-scale residential/septic work.

Regional players

• Andersen Construction: Portland, OR-based general contractor performing commercial, healthcare, and higher education construction across the PNW. Often hires Coffman as excavation subcontractor; competes at the GC level on hospital and campus projects Coffman serves via excavation scopes.

Emerging players

• Catworks Construction: Pacific Northwest excavation and site preparation firm with overlapping earthwork and underground utility services. Smaller and more regionally focused than Coffman but operates in adjacent PNW submarkets.
