The National Capital Planning Commission (NCPC), in cooperation with the General Services Administration (GSA), is sponsoring a design competition for a new temporary outdoor commemorative installation in Washington, DC with the goal of enhancing a prominent but underutilized public space in the city’s monumental core while fostering a public dialogue regarding the nature of commemoration in the nation’s capital.

The proposed site for this temporary installation is the Ariel Rios Hemicycle, a grassy semi-circle along the west side of 12th Street NW between Pennsylvania and Constitution Avenues in Washington’s Federal Triangle.

Artists and/or design professionals, working as individuals or teams, are invited to propose ideas for an innovative temporary commemorative work that embodies the commemorative theme selected for the competition — the precepts and positive impact of Earth Day, the world’s largest civic observance.

The winner of the competition – which will be selected in summer 2012 – may be contracted to design, fabricate, and install their proposed installation, resulting in a public display at the Hemicycle for a period of approximately one year.  Concurrent with this competition, GSA will be making permanent site enhancements such as new seating and improvements to the landscaping.
