高楼介绍：
The original marble cladding of Aon Centre bowed under the temperature swings experienced in the Chicago climate. The cladding was 32mm (1.25") thick Itallian Carrera Marble (similar to what Michaelangelo used), but 20 years after original construction it had severly deteriorated. The marble was replaced with 51mm (2") thick Mt. Airy Granite at a cost of $80M between 1990 and 1992 (43,000 individual 1.27m x 1.14m [50" x 45"] panels). The original construction cost in 1973 was a mere $120M
The building is 59.1 meters wide (194 feet), with 4.6 meter indents (15 feet).
