Development of Bilateral Data Transferability in the Virginia Department of Transportation's Geotechnical Database Management System Framework

About the report:

An Internet-based, spatiotemporal Geotechnical Database Management System (GDBMS) Framework was designed, developed, and implemented at the Virginia Department of Transportation (VDOT) in 2002 to retrieve, manage, archive, and analyze geotechnical data using a distributed Geographical Information System methodology. As the use rate of the GDBMS Framework grew, VDOT engineers recognized that additional engineering analysis and design functionalities could be incorporated. In response, five geotechnical engineering applications (DRIVEN, RSS, LPILE Plus, SHAFT, and GALENA) that are used to calculate slope stability, pile, and shaft capacity were identified. An Analysis and Design Module (ADM) for these five applications was developed and implemented in 2004. In 2005, additional automated file upload capability (Bilateral Data Transferability, BDT) was developed and implemented to allow VDOT engineers and geologists to upload completed geotechnical data files, with a pre-screening and QA/QC check prior to the final posting on the GDBMS server. This BDT module was implemented based on the latest gINT geotechnical data template and library used at VDOT. In addition, a new functionality to export dynamically generated fence diagrams into MicroStation in a DXF format was developed and implemented in GDBMS.
