WBK has completed sizable projects for AEP, ALCOA, Ameren, Big Rivers Electric, Duke Energy, Electric Energy Inc., Hoosier Energy, IP&L, and NIPSCO to name a few.  WBK performed all sitework for the Prairie State Generating Facility, in Marissa, IL, which may be the last coal fired power plant to be constructed in the United States. 

Faced with daily forecasts of rain, they persevered through the weather, worked when few others would have done so, and kept the project moving forward. I can heartily recommend WB-Koester Construction based on their performance on this contract.

WBK specializes in the construction of Coal Combustion Residual (CCR) Landfills and Ash Containment Impoundments that require liners of both impervious clays and synthetic geo-textiles to protect the environment.

WBK has earned a fine reputation for on-time delivery, value engineering, and outstanding quality of completed projects.  The team is well trained in the specialized skills required for excavation and grading in and around electric generating facilities.
