In the New Orleans area, tall buildings must be supported by piles extending at least into the preconsolidated clays at -150-ft (-46-m) or so. Settlement is much too severe and uneven in the soft upper clays. As a result designers of recent tall structures in the city have concentrated on finding which piles and foundation systems will serve in the deep tranfer of heavy loads. These findings have raised questions concerning building code requirements for pile tests and load transfers through the various foundation elements. Engineers in the area have gained some modernizing improvements by updating the building codes. The New Orleans codes are not revised as some say they should be, however, they have become one of the most progressive communities in the country.
