Using digital technologies to plan and manage the pipelines network in city

Promoting the intelligent level of urban pipelines network planning and management is an important way to improve rational development utilisation underground space ensure safe operation infrastructure systems. The research on using rapid visual expression technology 3D model data, which has functions techno-economic indexes calculation automatic comparison pipeline construction projects, effectively avoids possible errors in manual improves efficiency accuracy digital declaration process for project planning. In Geographic Information Systems (GIS) platform environment, this help develop many analysis approval based data integrated pipes gallery Building Modelling, such as evaluating compliance, feasibility scientific scheme project, comparing completion with approved by administrative departments consistency them judging compliance data. application results some actual projects cases show that can analysis.
