Wm. Winkler

What Wm. Winkler does

Wm. Winkler Co. is a third-generation, family-owned concrete and civil construction firm headquartered in Newman Lake, Washington, founded in 1919 by William Winkler. The company self-performs a vertically integrated set of services across seven lines: civil construction (excavation, utilities, grading), site concrete (curb, gutter, ADA ramps, paving), flatwork (slabs, driveways, high-F-number floors), structural concrete (bridges, foundations, tilt-up, parking structures), design-build custom projects (decorative, sports, amusement, wind and solar infrastructure), heavy-haul transportation via a fleet of 25+ trucks and trailers, and certified installation of Vanguard ADA tactile surface systems. Sister companies Pro-Recycle LLC (concrete recycling and on-site crushing) and INW Precast round out an internal supply chain that includes precast box culverts and aggregates.

The firm serves federal, state, local, and commercial customers principally in Washington, Idaho, Montana, Oregon, and Alaska, with project work recorded in Nevada and Texas. Federal exposure is anchored by Service-Disabled Veteran-Owned Small Business (SDVOSB) status, supporting contract wins at VA medical centers (Mann-Grandstaff), military installations (Joint Base Lewis-McChord, Fort Hood), and state DOTs (WSDOT Brooks Road). Commercial customers include Marriott, Costco, Walmart, Silverwood Theme Park, Avista, WSU, and Northern Quest Casino, indicating revenue diversity across hospitality, retail, utilities, education, and entertainment.

Revenue is project-based and earned through competitive bidding on public RFPs and negotiated commercial proposals, with multi-year contract cadences on federal work. Pricing is quote-based and varies by scope; no public pricing exists. Go-to-market is direct enterprise field sales augmented by industry-association presence (AGC, VOB, ASCC, SDVOSB, ACI, NUCA, WACA). Operational scale in 2024 included 200+ employees, 27,000+ yards of concrete poured, and 265,000+ man-hours worked, with 14 consecutive years of AGC Zero-Incident Safety Awards and multiple HUB Build Northwest excellence awards.
