Project Details

Client: McGough
Location: Pierre, SD
Services: Deep Foundations


In the May of 2023, McGough Construction awarded Bolander the design-build construction for the auger cast pile deep foundation system, for a building addition at the South Dakota State Historical Society Cultural Heritage Center, located in Pierre, SD.

Augercast piles are constructed by rotating a hollow stem continuous flight auger into the soil to a designed depth.  Concrete or grout is pumped through the hollow stem to fill the cavity created as the auger is slowly removed.  Once the continuous grout pile is complete,  a full depth center bar and reinforcement cage is placed through the freshly placed concrete.  Bolander installed (65) reinforced auger cast piles x 40’ deep for the building addition at this project.

In 1989 South Dakota celebrated its centennial and to mark the anniversary and showcase the state’s history, the Cultural Heritage Center was built as the new headquarters for the Society.  The building is temporarily closed and will reopen when the renovations and addition is complete in 2025.
