Smithsonian Institution
Mueller’s relationship with the Smithsonian Institution dates to the late 1970s and has included more than 100 projects for the world’s largest museum, education, and research complex. Since designing HVAC renovations at the National Portrait Gallery in 1978, we have completed renovations and new design projects at nearly all of the Smithsonian’s 21 museums in the United States as well as the National Zoo and several research, preservation, and collections storage facilities.
Most notably, since 2013, Mueller’s engineers have worked on the rehabilitation of the National Air and Space Museum, one of the world’s most popular museums. The $1-billion renovation of the 687,000 SF building includes replacing all building systems, upgrades to the exterior envelope, and renovations to galleries and other spaces.
Mueller is also working on the modernization of the historic Hirshhorn Museum and Sculpture Garden, a multi-year design project that will transform galleries and public spaces and enable the museum to address a significant increase in attendance in recent years. The project includes a complete rehabilitation of the interior and plaza, improved access, and updated infrastructure including building systems.
In addition, Mueller is currently working on the construction of Pod 6, a new 190,000 SF collections storage building at the Smithsonian’s Suitland Collections Center; the revitalization of the American Art Museum; several renovations at the National Zoo, the National Museum of African-American History and Culture, the National Museum of American History, and the National Museum of the American Indian; and renovations to the Smithsonian’s new consolidated headquarters in downtown Washington, DC.
