If you are looking for more information on these ice margin deposits you should look into The Park Ridge, Tinley, and Valparasio tills. These hardpan layers are overconsolidated silty clays, deposited as ice margin deposits. Most skyscrapers under 40-50 stories end bear on some of the "hardplan" layers. Large skyscrapers tend to bear on this layers. steel beams, and iron I-beams to float the Auditorium Building (1889). Dewatering of a lined drilled shaft is not a huge deal.ĭolomite bedrock varies in depth, but the project I'm most familiar with its at 155ft depth (-140ft CCD). It was this type of foundation that Burnham & Root used for the Montauk Block. In 2016, Urban Rivers and SOM installed a 1,500-square-foot floating garden as a first step toward making the Wild Mile vision a.
due to the deterioration of the framing and log float foundation.
This area has been envisioned as a type of eco-park since the creation of the 2003 Chicago Central Area Plan. While the Seattle area has enjoyed a long history of floating homes and houseboats. So all major projects deal with groundwater. The project is located along the east side of Goose Island, on the North Branch Canal and Turning Basin. I have to disagree with his statements on water though, drilled shafts have to deal with water anywhere in the Chicago area, the water table tends to be at about 14ft depth (0ft CCD). Since My graduate thesis is set in downtown Chicago and I'm also a geotech in the area.
