摘要:随着数字化水平的持续提升，数字建造已成为建筑业战略转型的关键路径。为了满足日益增长的居民对优质饮用水的需求，城市既有水厂的处理工艺需要进行全面升级和扩能改造。位于深圳市中心的某水厂扩能改造工程面临用地紧张、厂区管线保护、供水安全保障、水下湿法顶管作业以及复杂空间设备安装等多重施工挑战。通过应用倾斜摄影、GIS、Dynamo、Civil 3D、Revit、AR、BIM5D等技术，该项目实现了场地优化、多专业模型整合、模拟分析、可视化方案比选、三维技术交底及数字化项目管理，有效解决了上述问题。整体上，项目显著提高了施工效率和质量，实现了在不停产状态下的扩能改造，最终达到了提升质量和效率的目标。

Abstract: With the improvement of digitalization level, digital construction has become an important way for the transformation and strategic development of the construction industry. In order to fully meet the growing demand for high-quality drinking water among residents, it is necessary to comprehensively upgrade and expand the treatment processes of existing water plants in the city. The expansion and renovation project of a water plant in Shenzhen is located in the central urban area. The project has small construction land and faces construction challenges such as pipeline protection in the factory area, water supply safety assurance, underwater pipe jacking operations, and complex spatial equipment installation. By utilizing technologies such as oblique photography, GIS, Dynamo, Civil 3D, Revit, AR, BIM5D, etc., the project site optimization, integration of multiple professional models, simulation analysis, comparison and selection of visualization solutions, 3D technical disclosure, digital project management, and other applications have been achieved, effectively solving the above difficulties. The overall efficiency and level of project construction have been improved, and the water plant has been continuously expanded and renovated ultimately achieving the effect of improving quality and efficiency.
