    Mokpo Cable-stayed Bridge

    Mokpo, South Korea

Project Summary

The Ministry of Land, Infrastructure and Transport retained GS Engineering & Construction to design a 3.06 km cable-stayed bridge addressing the transportation demand between Mokpo’s North Harbor and the Muan International Airport. Designing a long, sea-spanning cable-stayed bridge required detailed designs, construction plans, geometry control, and massive data analysis. To accommodate the complex engineering demands as well as structural changes throughout the project, GS Engineering & Construction required integrated structural design and analysis software.

GS Engineering & Construction used Bentley’s RM Bridge to establish a construction plan and conduct geometry control. It developed a 4D bridge model and conducted Initial Force Analysis (IFA, equilibrium state analysis) and construction stage analysis. The processing capabilities and accurate analysis offered by RM Bridge enabled the team to manage enormous amounts of data and find compatible solutions for critical geometry control issues presented by the balanced cantilever method as well as the free-standing bridge pylon.  

Bentley’s software enhanced productivity, saved time and money (potentially USD 1 million), reduced errors, and optimized the technical design of the bridge. RM Bridge enabled GS Engineering & Construction to efficiently evaluate and select cable forces, ensure geometry control, deliver extensive data in spreadsheet formats, and adapt to changes in design and construction schedules, maximizing time and resources. The Mokpo cable-stayed bridge enhances transportation in the region and serves as a city landmark that draws travelers from around the world.

RM Bridge was instrumental in the design and construction engineering of the Mokpo Bridge. The integrated modeling, analysis, and output functions of the software enabled GS Engineering & Construction to manage site variations and complex engineering demands. RM Bridge allowed engineers to verify selected cable forces during construction stage analysis. Erection control helped manage geometry control, and provided a time-saving solution for the bridge’s free-standing pylon. RM Bridge’s wind dynamic module evaluated aerodynamic forces for the balanced cantilever construction and its simulation capability captured changes in construction plans and design of temporary structures.  
  • RM Bridge enabled GS Engineering & Construction to optimize the technical design of the new bridge and maximize time savings, potentially saving USD 1 million.
  • RM Bridge provided GS Engineering & Construction with an integrated structural analysis tool that satisfied the technical demand over the entire course of the project.
  • RM Bridge’s data processing and simulation capabilities allowed GS Engineering & Construction to handle massive amounts of data and capture construction changes, reducing project errors and optimizing quality and saving time.
