摘要:立体停车场总承包项目对深化设计、协同施工以及运营管理都有很高的要求，将各阶段的关键内容与BIM技术结合起来并充分发挥应用价值成为了本项目的研究重点。在可研阶段，结合地理区位的需求，应用无人机进行现场勘查，对勘查信息进行定量化的模拟分析，确保选址的合理性。设计阶段进行多专业协同设计，确保设计的深度。充分地进行管线综合优化保证停车场各层的净高，全面的结构受力分析保证安全性能的要求。虚拟建造过程中的施工模拟、成本控制、质量监控覆盖了设计与施工管理的各个环节，保证了项目的成功实施。在BIM模型的基础上进行二次开发，实现了基于BIM模型和软硬件间的数据传输与信息互联。本项目中基于BIM的停车场智慧管理系统提高了停车场的运营和综合管理水平。整个过程实现了项目全生命周期技术和经济指标的最优化。

Abstract: The general contracting project of 3D parking lot puts forward high requirement for deepening design, collaborative construction and operation management. The project mainly focuses on the combination of the key content of each node with BIM technology organically to fully play its value. During the planning stage, the quantitative simulation analysis is carried out to ensure the rationality of site selection. During the design stage, multi-professional collaborative design is carried out to ensure the depth of design. Also, full pipeline optimization is carried out to ensure the net height of parking lots, and comprehensive structural stress analysis is carried out to ensure safety performance requirements. During the virtual construction progress, construction simulation, cost control and quality control cover all aspects of design and construction management, which ensures the successful implementation of the project. Based on the BIM model, secondary development is conducted to achieve the data transmission and information inter-connection between the hardware and software. The BIM-based intelligence parking management system improves the operation and comprehensive management level of the parking lot, and optimizes the technical and economic indicators of the whole life cycle of the project.
