A study on setting the direction of digital twin implementation for urban regeneration business

Abstract

In Korea, after the period of urban development, many cities entered a period of decline. Accordingly, the market for urban businesses such as urban regeneration, redevelopment, and reconstruction is expanding. However, even though these businesses are large businesses that generate a lot of added value, there is a high risk that it is difficult to accurately predict the direction of the business and the profit and cost of the business. However, if a city digital twin is established from the perspective of an urban digital business, any reasonable market participant can promote urban regeneration, redevelopment, and reconstruction projects as an urban digital business. Therefore, in this study, from the perspective of urban digital business, the purpose of constructing a digital twin for urban regeneration digital business was to be presented by analyzing the case of establishing a digital twin of the urban regeneration project by the town as a case. As a result of analyzing the case site through public DB and on-site surveys, a total of 237 parcels and 156 buildings were analyzed. As a result, a total of 54 public Databases and actual cases were found to be inconsistent. Therefore, in this study, four directions were suggested for the establishment of a digital twin for urban regeneration digital business at the village level. The first is to secure consistency between the current government's public ledgers (public DB). The second is to improve the problem that it is difficult to check information such as empty houses. Third, it is a regular and detailed field survey to improve books that are inconsistent with various current conditions, such as when buildings are actually destroyed, but there are buildings on the ledger or buildings without a building register (most of them are expected to be illegal buildings). Fourth, the government's cost and time to develop and apply digital twin technology for the old cities, which are most cities in Korea, is a step away from what is currently being built/developed around pilot cities such as new towns and smart cities at the government level. It is commitment.
