Design, Monitoring, and Integrity Testing of Drilled Soil Displacement Piles (DSDP) for a Gas-Fired Power Plant

Abstract
Increasingly, Cast-In-Place (CIP) pile foundations are being used in place of traditional driven pile foundations to support settlement sensitive structures. The advantages of CIP pile foundations include quick installation, flexibility to adjust pile length for varying subsurface conditions, and reduced noise and vibration. There are inherent uncertainties in all CIP systems and thus detailed testing and production monitoring programs may be appropriate to verify the integrity of each individual CIP pile. This paper presents the design considerations, load testing program, production monitoring, and integrity testing of Drilled Soil Displacement Piles (DSDP) installed for a gas-fired power plant in Bartow, Florida. Efficient planning of the load testing and integrity testing programs resulted in the foundation construction being completed ahead of schedule while verifying the piles met the design requirements.
