ABSTRACT: The construction of a 34-storey residential building required a deep foundation system competent enough to support the applied loads, and, at the same time, mitigate excessive settlements. Continuous Flight Augercast (CFA) Piles were selected as deep foundation elements for the building. A CFA pile is a cast-in-place reinforced concrete pile, constructed in a single pass process. The main difference between a CFA pile and conventional bored piles is that the concrete is pumped through the hollow core auger during auger withdrawal, maintaining the drill hole stable throughout the whole drilling process. The CFA pile simple and quick installation methodology are key benefits when applied to deep soil profiles. The CFA piles were connected to the structure through a central raft and surrounding pile caps. An overview of the project, its geotechnical conditions, foundation design considerations, results of a full-scale static compression load test, quality control program, and the construction results are highlighted in this paper.
