To develop three-dimensional (3D) models as examples of the infrastructure model concept which would be useful for the operation and maintenance or design and construction of underground facilities we integrated 3D models of the geological composition, the structure and the lifeline facilities (water supply and sewerage system, city gas line, electrical power and communication lines) for the underground mall named ESCA in Nagoya City, Japan. In addition to the above 3D models, 3D structural models of tunnels of the underground railway passing underneath ESCA are developed based on as-built drawings in cooperation with the transportation authority of Nagoya City, and settlements occurred by that construction are visualized in 3D models from a record of the construction of tunnels of that subway. ESCA built out a 3D data platform with browser software for daily maintenance and planning of modification work of the underground mall.

为了开发 3D (3D) 模型作为基础设施模型概念的示例，这将有助于地下设施的运营和维护或设计和建造，我们集成了地质成分、结构和生命线设施（供水）的 3D 模型日本名古屋市名为 ESCA 的地下商场的污水系统、城市燃气管道、电力和通信线路）。除上述 3D 模型外，与名古屋市交通局合作，根据竣工图开发了通过 ESCA 下方的地下铁路隧道的 3D 结构模型，并在 3D 模型中可视化该施工产生的沉降。那条地铁隧道的建设记录。
