The Everett McKinley Dirksen Federal Courthouse is a 30+ story building in the central business district of downtown Chicago which houses federal government office spaces and federal courts with their associated offices, chambers, and support spaces. The building was designed by architect Mies Van Der Rohe and constructed in 1964 as part of his master plan for a two-block complex which includes the 42-story John C. Kluczynski Federal Building and the Central Post Office. It is a steel framed structure, clad with a glass and steel curtain-wall system.


To provide OPTIRA BIMplus™ documentation services to create and correct the existing as-built documents of the building and to further develop an architectural Building Information Model with the proper use of “architectural objects” that embody “object information” about slabs, floors, interior/exterior walls, and space. Optira BIMplus™ deliverables will be leveraged by current and future GSA project teams to avoid conflicts and change orders during construction and renovation projects, which occur throughout every space in the EMD Federal Building.
