The Pentagon Memorial was constructed from a design by
Julie Beckman and
Keith Kaseman of
Philadelphia, Pennsylvania, with design support from
Buro Happold and
Delta Fountains, that was chosen following a design competition. The design competition included a group of 11 judges, including
Terence Riley, the chief curator of architecture and design at the Museum of Modern Art, and two former secretaries of defense,
Melvin Laird and
Harold Brown. They viewed 1,126 memorial proposals from around the world. Of the six international finalists selected, all were designers: Jean Koeppel and Tom Kowalski, Mason Wickham and Edwin Zawadzki, Jacky Bowring, Shane Williamson, Michael Meredith, and Julie Beckman and Keith Kaseman. The design by Beckman and Kaseman consisted of 184 illuminated benches, arranged according to the victims' ages, starting with Dana Falkenberg, age 3, to John Yamnicky Sr., age 71, in a landscaped plot. Each bench is engraved with the name of a victim. The benches representing the victims that were inside the Pentagon are arranged so those reading the names will face the Pentagon's south facade, where the plane hit; benches dedicated to victims aboard the plane are arranged so that those reading the engraved name will be facing skyward along the path the plane traveled. A shallow lighted pool of flowing water is positioned under each memorial bench. If more than one member of a family died during the attack, family names are listed in the reflecting pool under the bench, in addition to the separate benches that have been created for each individual. A wall along the edge of the Memorial begins at a height of 3 inches (7.6 cm) and rises to a height of 71 inches (180 cm), the ages of the youngest and oldest victim of the attack, and about 85
crepe myrtle trees are planted on the memorial grounds. Funding of $13.8 million had been raised for construction of the memorial by May 2007. Donations include $250,000 from
American Forests towards planting trees at the memorial, and $1 million from the government of
Taiwan. Construction began on June 15, 2006. By November 2006,
site excavation, re-routing of existing
utility lines had been completed, and water lines laid for the
fountain pools. By May 2007, the foundation of the perimeter wall was built and concrete pilings poured for each bench. In addition to the Memorial, plans for the Pentagon Memorial Visitor Education Center were developed to further honor the vicitms through interactive exhibits and educational programming. PRD group led the VEC's design. ==Dedication ceremony==
