London, the NMAAHC is "further solidified as promoting or delivering change, enabling access, extending design practice, or capturing the spirit of the year." Ozwald Boateng OBE, a jury member, made a statement expressing his thoughts on the NMAAHC: "We couldn't look any further than the Smithsonian for the overall award. It is a project of beautiful design, massive cultural impact, delivers an emotional experience, and has a scale deserve of this major award." Topping out of the museum occurred in October 2014. That same month, the Smithsonian announced that the National Museum of African American History and Culture had received $162 million in donations toward the $250 million cost of constructing its building. To bolster the fundraising, the Smithsonian said it would contribute a portion of its $1.5 billion capital campaign to help complete the structure. The entire steel superstructure and all above-ground concrete pouring was complete in January 2015. Glass for the windows and curtain walls began to be placed that same month, with glass enclosure of the building complete on April 14, 2015. That same day, the first of the structure's 3,600 bronze-colored panels for the building's corona were installed. A worker was severely injured at the construction site on June 3, 2015, when scaffolding on the roof collapsed on top of him. 35-year-old Ivan Smyntyna was rushed to a local hospital, where he later died. The building has a total of 10 stories (five above and five below ground). Opening In January 2016, the Smithsonian set an opening day of September 24, 2016, for the museum's opening. President Barack Obama would dedicate the museum, which would be followed by a week of special events. The museum would open for extended hours during that week to accommodate crowds and visitors. NMAAHC officials said that construction scaffolding around the exterior of the building should come down in April 2016, at which time some of the more dust-and-humidity resistant artifacts and displays could be installed. Installation of more delicate items would wait until the building's environmental controls had stabilized the interior humidity and removed most of the dust from the air. The museum identified 3,000 items in its collections which would form 11 initial exhibits. More than 130 video and audio installations would be installed as part of these exhibits. In January 2016, the museum announced the receipt of a $10 million gift from David Rubenstein, CEO of The Carlyle
