Improving Citywide IT Infrastructure and Creating a Digital City

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.

Pivoting from a Three-year Timeframe to a One-year Schedule

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.

Robust Applications Help Meet Aggressive Schedule

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.   

BIM Design Key to Identifying and Resolving Clashes

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.

Outcome/Facts
  • The South Korea Ministry of Land, Infrastructure and Transportation is implementing a citywide IT infrastructure at Hanam to advance the city’s administration and lifestyle.
  • The Ministry outsourced the design oversight to BasisSoft to analyze and transform the existing 2D design into a 3D BIM to evaluate and improve design quality.
  • The client mandated a one-year timeframe rather than the initial three-year schedule making it impossible to convert all 2D designs to 3D designs and meet delivery.
  • The integrated BIM solution and Bentley software enabled BasisSoft to uncover 50 interference instances, 30 drawing error instances, and 10 design issues.
Quote:
  • Since the project is a design transformation, it was difficult to complete the BIM design within the deadline using the design materials as some were complete and some are still in progress. There was a large amount of BIM data and it was difficult to handle.
