392,040 sf Overstructure Greenroof
Greenroofs.com Featured Project May 26, 2020
In honor of Memorial Day yesterday, we are featuring the much awarded and sometimes criticized redesign of Soldier Field. Remembering the fallen in war, we pause to honor those who gave their lives for our nation. Originally Municipal Grant Park Stadium, its formal dedication as Soldier Field was held during the 29th annual playing of the Army–Navy Game in 1926.
The multiple architectural contributors for the 2003 renovation – Lohan Caprile Goettsch and Wood+Zapata – are to be lauded for their complex engineering and design of the modern bowl while carefully preserving Soldier Field’s historic classical colonnade facade. And the design of the North Burnham Park and massive overstructure greenroof by Schaudt Landscape Architecture with Jeffrey L. Bruce & Company as consultant was an early example of groundbreaking, lightweight landform work.
In addition to the Soldier Field Facebook page, thank you to these fine individuals for sharing their photography: Hoerr Schaudt Landscape Architects, Goettsch Partners, Carlos Zapata Studio, and Dan Boro of Absolute Altitude Aerial Photography!
Excerpt from Greenroofs.com Project Profile:
Dedicated to the men and women of the armed services, Soldier Field is located on famous Lake Shore Drive in Chicago, the first NFL Stadium to become LEED certified. Currently home to the NFL’s Chicago Bears since 1971, it is also the oldest football field in the U.S. and an overstructure greenroof.
Originally Municipal Grant Park Stadium, it was designed by Holabird & Roche and opened in 1924. The name was changed to Soldier Field in 1925 as a memorial to U.S. soldiers who had died in combat. Compared to other NFL facilities, the stadium was outdated and its $382.5 million revitalization was part of the City of Chicago’s Lakefront Redevelopment Project.
A joint venture of two firms redesigned the multi-ward winning project: Goettsch Partners (formerly Lohan Caprile Goettsch) and Ben Wood (now Principal of Studio Shanghai) and Carlos Zapata (now Principal of Carlos Zapata Studio). Famous for its historic concrete Doric colonnades, the exterior of the classically styled arena was preserved in 2003, with a controversial new modern glass and steel structure set inside.Complex radial geometry resulted in cantilevers being used extensively. The 20-month renovation modernized the stadium and surrounding 98 acre parkland for multi-purpose event use.
Previously surrounded by 66 acres of paved parking, the design by Hoerr Schaudt Landscape Architects sinks the stadium’s garage beneath a nine-acre greenroof and uses sculpted landforms to surround Soldier Field with seventeen acres of parkland. The new green space includes a Children’s Garden, winter sledding hill, War Memorial Wall, and improvements to the Police Memorial.
The renovation of Soldier Field was a key milestone in the development of greenroofs, and one of the first to utilize geofoam on such a large scale: the sculpted landforms conceal the 2,500 underground parking spaces.
The sloping greenroof park is covered with shade trees of maple, ash, and linden, turf, and various perennials.
Chicago residents and visitors enjoy year-round access to the juxtaposition of the timeless neo-classical and new modern design of Soldier Field and experience unique views of the Chicago skyline and Burnham Harbor. The wide expanse of unique lakefront parkland, including the 9-acre public access greenroof, makes Soldier Field a “Stadium in a Park.”
