Major renovations at the historic Fayette County Courthouse

During the revitalization of Lexington, Kentucky’s downtown, the historic Fayette County Courthouse required major renovations to accommodate the additional planned shop and restaurant space. The project involved increasing loads on existing footings, as well as dropping the basement elevation and undermining the existing historic foundation. The difficulty with the structure’s expansion was access to the basement, question of the foundation’s existing load carrying capacity, and underpinning the building within the limited confines of the city block’s installed utilities.

Geostabilization International® helped develop an overall solution for underpinning portions of the 4-story structure and enabling access to the basement level for the proposed expansion. Working in conjunction with the structural engineer and general contractor, GeoStabilization formulated a plan to underpin relevant portions of the existing structure with a combination of micropiles and conventional underpinning pits. Additionally, the solution utilized micropiles to create an A-Frame shoring system that allowed access to the current basement for the renovations and expansion and overcoming challenges presented by the overhead electrical hazards.
