The architecture, engineering and construction (AEC) industry lacks a framework for capturing, managing, and exchanging project, product, and social information over the lifecycle of a building. The current tools have various limitations, such as lack of interoperability, slow to transfer huge building model files, and possibility of data inconsistency. In this paper, we present a cloud-based BIM server framework namely Social BIMCloud that facilitates BIM information exchange through dynamic merging and splitting of building models. The data model of Social BIMCloud is based on but not limited to IFC. The data model of Social BIMCloud was further extended to accommodate social interactions, by studying the formal modes of communication in the AEC industry. An object-based approach to capture and manage social interactions in AEC projects through a BIM-based visual user interface was also developed and demonstrated. Social BIMCloud addresses the issues of inefficient data transfer speed and data inconsistency in a distributed environment by facilitating the storage and partial exchange of integrated nD BIM models. Data interoperability is facilitated through open BIM standards such as IFC and direct integration with construction software. High performance, scalability, fault tolerance, and cost effectiveness are facilitated through data partitioning, data replication strategies, multi-node structures, and pay-per-use tariff systems, respectively, through a cloud-based NoSQL database. The Social BIMCloud framework helps to develop and exchange BIM models, which are rich in project information such as social interactions, cost, and energy analyses. This framework improves the communication efficiency between project participants, leading to better designs and less rework. The information captured by this framework could also be useful to determine important metrics such as industry trends, relationships among project participants, and user requirements.

社交BIMCloud：一个基于云的分布式BIM平台，用于基于对象的生命周期信息交换

建筑，工程和建筑（AEC）行业缺少在建筑物的整个生命周期中捕获，管理和交换项目，产品和社会信息的框架。当前的工具具有各种局限性，例如缺乏互操作性，传输大型建筑模型文件的速度缓慢以及数据不一致的可能性。在本文中，我们提出了一个基于云的BIM服务器框架，即Social BIMCloud，该框架通过动态合并和拆分建筑模型来促进BIM信息交换。Social BIMCloud的数据模型基于但不限于IFC。通过研究AEC行业中的正式沟通模式，Social BIMCloud的数据模型进一步扩展为适应社交互动。通过基于BIM的可视用户界面，还开发了一种基于对象的方法来捕获和管理AEC项目中的社交互动。Social BIMCloud通过促进集成nD BIM模型的存储和部分交换来解决分布式环境中数据传输速度低下和数据不一致的问题。通过开放的BIM标准（例如IFC）以及与施工软件的直接集成，促进了数据互操作性。通过基于云的NoSQL数据库，分别通过数据分区，数据复制策略，多节点结构和按使用付费收费系统，可以促进高性能，可伸缩性，容错性和成本效益。社交BIMCloud框架有助于开发和交换BIM模型，其中包含丰富的项目信息，例如社交互动，成本和能源分析。该框架提高了项目参与者之间的通信效率，从而导致更好的设计和更少的返工。该框架捕获的信息还可以用于确定重要指标，例如行业趋势，项目参与者之间的关系以及用户需求。
