Accelerated Bridge Construction (ABC) for Georgia City and County Roads Part I: Overview and Survey Results
Location
Atrium
Session Format
Poster Presentation
Research Area Topic:
Engineering and Material Sciences - Civil
Abstract
The purpose of this project is to develop a toolkit for the design and construction of bridges using prefabricated materials primarily to reduce the closure time and on-site construction time of bridges. The research focuses specifically on short span bridges in Georgia (40,60,80, and 120ft spans). The means by which the toolkit is to be developed abides primarily in the information provided by state departments of transportation [DOT(s)].
Special attention was given to various areas of ABC, generally regarding design, constructability, and analysis, and specifically regarding the use of concrete and steel girders, concrete-steel girders, pre-stressed concrete, as well as cost efficiency, success and error reports from other states’ completed projects, and industry surveys. In this particular portion of the study, the surveys proved to be most effective when combined with information obtained from journals relating to the research as well as published project reports by contractors and DOTs. The surveys were created by the research team and included questions regarding the engineering entity’s experience with ABC, the level of acceptance of ABC techniques in their state, the number of completed projects in recent years, impediments to the use of ABC techniques, and the ongoing research on ABC topics in the entity’s state.
As formerly stated, constructability issues were given special attention, as they proved to be a major impediment to the use of ABC by other entity’s which remain reluctant. Lack of general experience also played a major role. The Georgia DOT seeks to possibly employ ABC techniques in the future, so this project will help identify what is needed to begin designing projects that utilize ABC and what further research needs to be conducted and which design details need more attention.
