Abstract:
The past decade has seen a new round of development of heavy and high-rise structures in urban environments in the Southeastern United States. The weight and height of these structures often results in a wide range of column reactions (compression, tension and lateral) requiring significant deep foundation support. Due to the population density of these urban centers, the project footprint is often small and available workspace is at a premium. Additional logistical challenges (material supply, general site access, etc.) are also present due to the environment surrounding the project site. The presentation will include an overview of recent deep foundation trends that have developed to address these issues. Specific technologies that will be discussed include ACIP and CFA piles, Drilled Displacement piles, and Rigid Inclusions.
