Evaluation of Existing Deep Foundation Performance Using FDOT Database to Improve Current Design Methodologies

The Florida Department of Transportation (FDOT) funds thousands of insitu and geotechnical laboratory tests every year. Bridge foundations often require load tests during construction. Electronically preserving the resulting data enables reusability in future FDOT projects, including bridge maintenance. Utilizing an Internet based geotechnical database to digitally preserve the data enhances the value of the data in many significant ways. Based online, geotechnical consultants will be able to directly upload results derived under FDOT contracts. A relational database enables searching of the data in order to form meaningful and relevant datasets. A geotechnical XML schema was developed to handle the communications between the users and the database. The XML schema was used to develop Microsoft Excel spreadsheets that could upload and download from the database. The geotechnical XML schema will also promote the development of commercial software for consultants. The database was populated with various completed projects within the state of Florida. This was accomplished with the previously mentioned Excel spreadsheets. The data were subsequently used to calibrate Load and Resistance Factor Design (LRFD) resistance factors for the BSI developed FB-Deep software program.
