Electronic Database for PIle LOad Tests in Iowa (PILOT-IA): Paradigm for Data Archiving Needed for Regional LRFD Calibration

The recently established database for PIle LOad Tests in Iowa (PILOT-IA) is an amalgamated, electronic source of information consisting of both static and dynamic data for pile load tests conducted in the State of Iowa. The database, which includes historical data on pile load tests dating back to 1966, is intended for use in the establishment of resistance factors for Load and Resistance Factor Design (LRFD) and a reliable construction control method for driven pile foundations in Iowa. Although a considerable amount of geotechnical and pile load test data is available in literature as well as in various State Department of Transportation files, PILOT-IA is one of the first regional databases to be exclusively used in the development of resistance factors for LRFD and a reliable construction control method for pile foundations. Currently providing an electronically organized assimilation of geotechnical and pile load test data for more than 270 piles of various types (e.g., steel H-shaped, timber, pipe, monotube, and concrete), PILOT-IA is on par with such familiar national databases used in the calibration of LRFD for pile foundations as the FHWA Deep Foundation Load Test Database. By narrowing geographical boundaries while maintaining a high number of pile load tests, PILOT-IA exemplifies a model for effective regional LRFD calibration procedures. Using the findings associated with a regional calibration of LRFD resistance factors for the construction control of driven piles in Iowa by means of dynamic pile driving formulas, the economy associated with a regional database such as PILOT-IA is demonstrated.
