In the 1960s and 1970s, efforts were under way to "finish" Federal Triangle by building a large office building on the site of the parking lot. The first effort came in 1972, when the Nixon administration proposed building a $126 million office building on the lot in time for the national bicentennial in 1976. But this proposal was never seriously contemplated or funded. One outcome of the Nixon proposal was "the Weese Plan. " The Nixon administration commissioned the architecture planning firm of Harry Weese & Associates to come up with a master plan for the continued development of Federal Triangle. The Master Plan (which became known as "the Weese Plan") did not only propose a massive new federal office building on the parking lots of the Triangle. It also proposed a new series of pedestrian paths throughout the complex, titled "Federal Walk. " Federal Walk would not only be a network of sidewalks designed to showcase the architecture of Federal Triangle; it also included destinations such as spots for tourists to wait for tours of the interiors of each building, outdoor art, places for rest and contemplation, and even cafes and restaurants. Federal Walk was gradually implemented in piecemeal fashion over the next 15 years, although it still remained incomplete as of 1997. GSA held a competition in 1982 to select a design for a 10-story office building to replace the parking lot, but planning bodies refused to approve the plan.
