text: Congress had appropriated $10.3 million for the new structure, which was designed to accommodate more than 3,000 workers.Its eight stories would be laid on a granite foundation and the sides clad in limestone. On December 1, 1932, the contract for construction of the limestone National Archives building (whose estimated construction cost was $5.284 million) was awarded to the George A. Fuller Company (which had constructed the New York Times Building and the Flatiron Building). Hoover laid two cornerstones on December 15 for the Labor/ICC building, the third building to begin construction that year. Workers who were Freemasons assisted the President in laying the cornerstones. Hoover personally oversaw the dedication of the cornerstone at the Labor end of the building. His words were broadcast over loudspeaker to the workers at the ICC end of the structure, who placed the ICC cornerstone simultaneously at the President's instruction (becoming the first time in Washington history that a single person dedicated two cornerstones at the same time). William Green, President of the American Federation of Labor, attended the laying of the cornerstone for the Labor building. Once more, Hoover used the trowel used by Washington to lay the cornerstone of the Capitol.
