Millennium Park Geofoam Project Profile

Millennium Park – (Chicago, Illinois)

The construction of Millennium Park used Foam-Control Geofoam to help transform unsightly railroad tracks and parking lots into a 24.5 acre park with an unprecedented collection of artwork from world-renowned artists.

Directly below Millennium Park is an existing 2186 car underground parking structure. In order to keep this existing parking structure safe and operational the lightweight geofoam was used in place of soil to reduce weight. This allowed the additional weight of the park structures and related park facilities to be added. Foam-Control Geofoam was also used to create landscape features around the park which helped the designers create the look they wanted while achieving the proper water drainage for the overall site plan. An additional advantage was that construction could be completed in various weather conditions, including the harsh Chicago winter.
