CDE概念较早出自英国标准BS 1192:2007《建筑、工程与施工信息协同编制——实践规范》(Collaborative production of architectural, engineering and construction information – Code of practice),随后在PAS 1192-2:2013《建筑信息模型(BIM)在建设项目资本/交付阶段的信息管理规范》(Specification for information management for the capital/delivery phase of construction projects using building information modelling)中被进一步细化。
2018年ISO 19650系列标准成为国际通用的BIM信息管理标准。ISO 19650-1《建筑和土木工程信息的组织和数字化,包括建筑信息模型(BIM)利用建筑信息模型进行信息管理 第1部分:概念和原则》(Organization and digitization of information about buildings and civil engineering works, including building information modelling (BIM) — Information management using building information modelling — Part 1: Concepts and principles)给出了CDE的定义:
“agreed source of information for any given project or asset, for collecting, managing and disseminating each information container through a managed process.
Note 1 to entry: A CDE workflow describes the processes to be used and a CDE solution can provide the technology to support those processes.”
“named persistent set of information retrievable from within a file, system or application storage hierarch.
EXAMPLE Including sub-directory, information file (including model, document, table, schedule), or distinct sub-set of an information file such as a chapter or section, layer or symbol.
Note 1 to entry: Structured information containers include geometrical models, schedules and databases. Unstructured information containers include documentation, video clips and sound recordings.
Note 2 to entry: Persistent information exists over a timescale long enough for it to have to be managed, i.e. this excludes transient information such as internet search results.
Note 3 to entry: Naming of an information container should be according to an agreed naming convention. ”
近年来,在国家大力推进”数字中国”建设的战略背景下,数字化转型已成为工程建设行业的重要发展方向。建筑信息模型(BIM)、城市信息模型(CIM)、数字孪生、人工智能等技术的融合应用正在推动行业向更高效、更智能的未来迈进。在这一转型过程中,通用数据环境(Common Data Environment,CDE)作为BIM数据管理与共享的关键基础设施,正在全球范围内得到广泛关注和应用。
通用数据环境(CDE, Common Data Environment)包括软件、硬件、数据资源,服务于建筑信息模型(BIM)中的数据管理与数据共享。为进一步推动行业对 CDE 概念、软件产品及最佳实践案例的了解,buildingSMART中国携手中国图学学会建筑信息模型(BIM)专业委员会联合举办“第十四期BIM大讲堂暨通用数据环境(CDE)大会”。本次会议将汇聚国内外众多行业专家、企业代表及技术供应商,共同探讨如何通过 CDE 的建设与应用,加速企业数字化转型,实现更加高效、可持续的数据管理与项目交付。
