What W.B. Koester Construction does

WB•Koester Construction, LLC (WBK) is a full-service mass excavation and grading contractor headquartered in Evansville, Indiana. Operating for over 40 years across the Midwest (IN, KY, IL, TN), the company delivers heavy civil construction services in four primary markets: Power Generation, Industrial & Commercial Site Development, Coal Mining & Quarry Operations, and Transportation Infrastructure. Core capabilities include site development, clearing and grubbing, mass excavation and grading, storm water control, rail sub-grade and drainage, aggregate placement, soil stabilization, land reclamation, and wetland mitigation.

WBK's differentiation is concentrated in two specialized scopes: Coal Combustion Residual (CCR) landfill and ash containment construction (involving impervious clay and synthetic geo-textile liners), and Unit Train rail load-out loop construction (single- and double-track, 75–100 car configurations). The firm has executed projects at scale — including 2.75 million cubic yards excavated at Prairie State, 1M+ cubic yards at the Evansville Airport runway reconstruction, 465,000 cubic yards of CCR landfill work for Electric Energy Inc., and 350,000 cubic yards of cut/fill in 45 days at Columbia Sportswear's 500,000 SF distribution center. Marquee customers include Duke Energy, AEP, Ameren, NIPSCO, Hoosier Energy, ALCOA, Toyota, Columbia Sportswear, Walmart, Gibson County Coal, Alliance Coal, Sunrise Coal, INDOT, CSX, and the FAA/Evansville Airport Authority.

WBK is a divisional subsidiary of Weddle Bros. Construction Co., Inc. The business operates as a private LLC with no disclosed revenue or funding. Revenue is generated through project-based competitive bidding and direct enterprise contracting across power utilities, industrial manufacturers, mining operators, and government transportation agencies. The company markets primarily through its project portfolio and long-tenured client relationships rather than digital channels.
