Hanam Gyosan is one of Korea’s new city development areas, covering almost 6.5 million square meters in the Gyeonggi province. It aims to create 32,000 residential houses, critical to helping the country overcome its housing issue. Previous large-scale development projects used 2D drawings and conventional methods to generate digital topographic and land registration maps, and capture survey data. These strategies provided inaccurate results, making it difficult to incorporate changes in the communities.

For this project, the team used drone photography and ContextCapture to survey the development site and generate a 3D topographic reality model that was compatible with Bentley’s BIM applications, enabling effective utilization of the model and data. The solution resulted in the generation of accurate digital twins while saving time and costs for the design, while also providing a visual digital representation to support and enhance decision-making.
