专家说,通过为模型建设提供路线图和通用语言,用于建立信息模型的设置和交换的第二个共识标准的第二版。

“这确实是一个很大的变化,”美国国家建筑科学学院建筑公司联盟执行董事兼标准开发商Deke Smith说。但是他还说,要做的工作还有很多工作要做,在达到更加成熟的标准的途中要克服障碍。他谈到上个月发布的版本时说:“我们只抓到了这些努力。”在标准的第三版上的工作将于八月开始。

华盛顿特区联盟负责开发国家建筑信息模型标准状态2版(NBIMS-US V2)。该小组的主要目标是帮助试图实施BIM的从业者。史密斯说,另一个目标是为下一代软件提供信息,在人们改变了业务的方式并可以充分利用BIM之后。

The purpose of the standard is to provide a means of organizing and classifying electronic object data associated with a facility throughout its life. A section for software developer-vendors offers reference standards developed by allied organizations as well as exchange standards written and balloted by the standard’s project committee. For BIM users, the standard contains best-practice guidelines and more.

一般共识是,该标准有助于满足设施所有者和从业者寻求BIM指导的需求。此外,该标准将作为定义数据交换并推进其他国家 /地区最佳实践的催化剂。

Many vendors view the release of the standard as a significant step forward. For ArchiCAD vendor Graphisoft, it is a validation of the Open BIM initiative, led by members of the alliance. The initiative is a universal approach to the collaborative design, realization and operation of buildings based on open reference standards, information exchange standards, best practices and workflows—particularly with regard to interoperability based on Industry Foundation Classes (IFCs).

其他人更谨慎。“我认为,在某个时候,供应商将将NBIM或部分内容纳入其各种创作工具中,” 3D软件供应商Nemetchek Vectorworks的综合实践副总裁Robert Anderson说,他还拥有Graphisoft。他补充说:“到目前为止,他们真的还没有。”矢量工厂的重大推动是符合IFC认证,而不是NBIMS。

他说,根据IFC,将IFC视为砖块和NBIMS。“直到IFC处于工作状态之前,在NBIMS上工作才有意义。”

他解释说,软件开发人员可以实现的NBIM部分是模型视图定义。MVD是使用IFC传输信息的更紧密定义的方法。

There are myriad technical and cultural obstacles to NBIMS development. Huw Roberts, a vice president with engineering software vendor Bentley Systems Inc., says the industry needs greater owner participation and validation of standards.
