McKissack provided design-build and program management services for physical security barriers and historic renovations on the National Mall.
McKissack served as the prime contractor for both the Lincoln and Thomas Jefferson Memorials, as well as provided construction management-at-risk services for roadway relocation. The Lincoln Memorial stands at the west end of the National Mall as a neoclassical monument to the 16th president. The side chambers contain carved inscriptions of Lincoln's Second Inaugural Address and his Gettysburg Address. The Thomas Jefferson Memorial is a memorial to our third president. It is an original adaptation of Neoclassical architecture and the circular colonnaded structure, in the classic style, was introduced to this country by Thomas Jefferson. The preservation work included the colonnade floor, soffit, volutes, parapet and entablature, dome and colonnade ceiling, and any miscellaneous areas as identified.
