Quality Control of Drilled Displacement Piles through an Integrated Automatic Data Acquisition System
In a set of companion papers presented at GeoCongress 2006, the authors described a Data Acquisition System that is included on the installation platforms for drilled displacement piles and, in general terms, defined how the acquired pile installation data can be used both for quality assurance / control and as an element of the pile design process. The system described was subsequently used by Berkel and Co. Contractors Inc (Berkel) as part of a design-build project in Orlando FL in March and April of 2006. The acquired installation data was used in the following manner. First, the pile installation data acquired during the preliminary foundation design and performance testing phase was used for final design of the foundation system for the project. Secondly, the data acquired during production pile installation was used, in real-time, for quality assurance / control during the project's entire pile installation phase. In addition, daily review of the acquired pile installation data revealed subsurface anomalies in one portion of the site that were subsequently attributed to other subsurface construction activities that occurred immediately prior to pile installation. The authors demonstrate how these anomalies were detected, how appropriate capacities were assigned to the piles in question and how appropriate remediation measures were planned and executed. Unless otherwise noted, the use of the term "pile" or "displacement pile" in this paper refers to the Berkel Displacement Pile (as described in NeSmith, 2002). Likewise, design methodologies and construction recommendations described herein also refer specifically to this foundation system.
