Illinois State Capitol Phase IV

Location:

Springfield, IL

Client:

Core Construction and River City Construction

Background

The State of Illinois began renovations on the 155-year-old Capitol Building’s north wing, including basement modifications and a new underground conference center.

Schnabel’s Solution

Schnabel provided excavation support and underpinning for a 30-ft deep excavation adjacent to the Capitol. Work included 190 piles, 140 permanent tiebacks, and 880 SF of underpinning, using both hand-dug and mechanically-dug pits.

Results

Despite limited access, overhead utilities, stiff clay, and groundwater conditions, Schnabel delivered safe, cost-effective support that preserved the historic foundation and enabled future expansions.
