Pile positioning, for driving piles below the surface of water in a marine pier construction project, is typically a time-consuming task owing to the fact that the pile wharf is affected significantly by environmental limitation and marine meteorology. As a result, it is always a goal to minimize the positioning time while maintaining a desired level of accuracy. This study developed a global positioning system (GPS)-based information system, which integrated six major modules. This system was designed to provide a real-time positioning and guidance solution for pile-driving barge control in a marine pier construction project. In a case study, the developed system has been implemented successfully in a real project and proved this system can improve the horizontal accuracy of real-time pile positions by less than 1 cm. It also contributed to a 42% reduction in the construction time and thus an 11% reduction in the final budget. Consequently, the efficiency of a piling construction project could be improved significantly by incorporating such a system. DOI: 10.1061/(ASCE)SU.1943-5428.0000096.
