Just over a week after caisson work started on the other side of the block (676 North LaSalle) at The Ardus, caisson work got underway this morning at 675 North Wells Street in River North, home of the future Marlowe development from Lennar Multifamily Companies. Stalworth Underground has the honor of ripping holes in the soil and filling them with concrete for the 15-story, 176-unit apartment project. Antunovich Associates took care of the designs; Power Construction will be on the build.
The good word from Stalworth is there will be 59 bell caissons dug at Marlowe, down to about 80 feet. Diameters range from 2-and-a-half to 3-and-a-half feet, with bells up to 10 feet.
