Landscaping of the park required an initial supply of more than 20,000 tons of natural sand, involving 25 trucks to deliver product over 60 miles to the job site in downtown Chicago. As the landscaping progressed, Holcim was asked to provide additional material to blend with topsoil for areas of the park requiring excellent drainage, such as at the base of the ice-skating ribbon, on walking trails and underneath the turf.
Holcim submitted for consideration a material that is a byproduct of producing Torpedo sand, a material often used in concrete and asphalt applications. In addition to its excellent drainage and other performance properties, this material also offers significant sustainability advantages due to its beneficial product reuse characteristics. The Chicago Department of Transportation conducted extensive quality testing of the sand and, with its approval, the general contractor requested 20,000 tons of the material to complete the project.
Based on the success of Maggie Daley Park, the general contractor used 5,000 tons of sand from Holcim US for another Chicago park development. Called “The 606”— named for the 606 ZIP code all Chicagoans share — the 3-mile-long trail and park system transformed an unused elevated railway into a riding trail and multi-use park. The first of its kind in Chicago, The 606 has become a true community corridor and one of Chicago’s great promenades for biking, running and strolling.
