This week, drilling began for the first caissons that will support the underground parking garage. Caissons are a network of underground concrete pilings that support structures—in this case, the Obama Presidential Center campus! Preparatory work also began for the caissons that will support the Museum Building. Drilling for those caissons will begin this Monday, December 13.
Drilling and installation of geothermal energy wells continues on schedule.
