In the construction industry, we expect the construction related industries such as architectural design, maintenance and inspection will be activated by expanding and opening architectural information. In fact, some companies that have implemented the trial using open data are expected to save about 2.5 billion won per year for location analysis and real estate consulting, and about 6 billion won per year for new and renewable energy industry consulting.
