With the current trend of urban development moving toward digital cities, the South Korea Ministry of Land, Infrastructure and Transportation is equipping their cities with infrastructure technology. In concert, the Ministry is implementing a citywide IT infrastructure at Hanam to advance the city’s administration and lifestyle. A digital transformation plan is also underway, considering various elements including existing city areas and innovative business zones. The project will decentralize urban housing in Seoul and contribute to the development of local communities.
The Ministry outsourced the design oversight to BasisSoft, a leading construction IT solution provider in South Korea. They were engaged to analyze and transform the existing 2D design into 3D BIM to evaluate and improve design quality. With a project area of nearly 6.3 million square meters to build 34,000 houses, the BasisSoft team sought a software application robust enough to handle the BIM design of a very large site. Further, BasisSoft needed to pivot from the initial three-year timeframe to a one-year schedule mandated by the client. The truncated timeframe made it impossible to convert all 2D designs to 3D designs and meet delivery. As a result, they needed a software solution that was easy to use and could quickly perform the conversion.

To meet the aggressive schedule, they deployed ContextCapture to process 20,000 drone-captured images of the site. They also deployed Leapfrog for 3D strata modeling and OpenRoads to handle the BIM design of the extremely large project site, which included calculating earthworks and road work, storm drains, sanitary sewers, and water supply lines. BasisSoft also used OpenBridge Modeler to facilitate structure design, as well as MicroStation for appurtenant works modeling and LumenRT for visualization.
Using the integrated BIM solution and Bentley software in their design enabled BasisSoft to uncover 50 interference instances, 30 drawing error instances, and 10 design issues. Additionally, accurate visualization helped them detect and resolve potential design errors that were critical in meeting the client’s aggressive schedule.
