Along with the several iconic
construction projects that The Conco Companies have been involved with in
California during the last couple of years, the rest of the country has also seen
some pretty incredible projects completed.
One example is the Smithsonian’s National Museum of African American
History and Culture (NMAAHC) in Washington D.C. that just had its opening
dedication ceremony on September 24th.
The design for the building was
awarded to lead designer David Adjaye and lead architect Philip Freelon and
their architectural firm of Freelon Adjaye Bond/SmithGroup. The firm was selected after winning an international
competition that took place in April 2009 with a design that “synthesized a
variety of distinctive elements from Africa and the Americas into the
building’s design and structure.” Construction
on the five-acre site began in February of 2012.
The Clark Construction Group, Smoot
Construction, and H.J. Russell & Company were joint general contractors on
the project. The first African
American-owned architectural firm in the U.S., McKissack & McKissack,
worked on behalf of the Smithsonian and provided the project with management
services.
The 350,000 square feet museum has a
total of ten floors with five above ground and five below and is the deepest building
on the National Mall. Site work included
digging an 80-foot deep foundation for the building. The first concrete was ready to be poured in
November of 2012, and during work on the lower levels, a crane was used to
install a segregated railroad passenger car as well as a prison tower. Both pieces would have been too large to
bring as more of the building was completed.
The NMAAHC was topped out in October
2014 and the steel superstructure and above-ground concrete was completed in
January 2015. An architectural highlight
of the museum includes 3,600 bronze-colored panels that wrap around the entire
building in homage to the lattice ironwork crafted by many enslaved African
Americans throughout the South.
Conco’s mission is to be the best
supplier of concrete services in the Western United States and to bring
expertise, experience and quality to each project. We continue to upgrade and expand facilities
to better serve the growing market for public works projects, commercial,
parking structures, educational, and other construction development. We serve
California, Washington State, Oregon, Colorado and Nevada.
