Abstract
The analysis and design of foundations for the World's Tallest Building are described. The results of the exploration and in-situ testing program required to define the foundation support conditions are presented. The Towers are supported on a mat foundation on barrettes in residual soil and weathered silt stone, sandstone formation overlying karstic limestone at depths ranging from 80 to more than 200 meters. The extensive grouting program required to fill major cavities in the limestone beneath the Tower mats is described. The settlement analysis performed utilizing modulus information developed from the in-situ testing program is outlined. Barrette lengths were varied above the steeply sloping limestone bedrock in order to minimize the calculated differential settlement. Settlement measurements taken during construction indicate actual total and differential settlements less than predicted. The barrette strain gage and mat pressure cell instrumentation program is outlined and preliminary results to date presented.
