Model-server-based integration for buildings and municipal infrastructure

建筑行业正经历着向建筑信息模型（BIM）的根本性转变——基于建筑项目综合语义数据模型的系统。BIM技术允许更智能的设计和分析工具，这些工具现在正在进入工业实践。更重要的是，BIM允许所有用户通过共享项目数据模型共享项目信息，从而实现更大的信息协作。然而，工业对基于bim的互操作性的采用仍然很少，很大程度上是因为它通常依赖于文件共享来交换信息。当一个应用程序的输出被用作另一个应用程序的输入时，这是合适的，但是当多个用户并发地处理共享项目数据模型的不同视图的多个版本时，它不能支持全面集成。解决方案是以标准工业基础类（IFCs）的形式在专门用于支持大型复杂工程项目数据模型的数据库中实现BIM模型：模型服务器系统。PI最近获得了CFI奖，为我们基于模型的建筑和市政基础设施研究获得了一个模型服务器测试平台。使用这个测试平台，本研究的目标是克服技术和组织方面的挑战，实现全面的BIM互操作性。特别关注的是三个应用领域，每个领域都扩展了BIM技术的传统范围：项目管理信息的集成；整合市政基础设施管理信息，整合支持可持续建设实践的信息。三名博士生将在全面项目中与工业合作伙伴进行互动，以确定具体的工作流程目标，在必要时扩展ifc以对所需数据进行建模，在模型服务器和相关工业软件应用程序之间构建原型接口，进行详尽的互操作性测试，并按照我们之前开发的项目信息管理方法以最佳实践的形式准备结果。

The construction industry is undergoing a fundamental shift towards building information models (BIM)--systems based on comprehensive semantic data models of construction projects. BIM technology allows smarter design and analysis tools, which are now emerging into industrial practice. More significantly, BIM allows much greater information collaboration by enabling all users to share project information through a common shared project data model. Yet industrial uptake of BIM-based interoperability remains minimal, largely because it usually relies on file-sharing to exchange information. This is appropriate where the output of one application is used as input to another, but it cannot support full-scale integration where multiple users concurrently work on multiple versions of different views of a shared project data model. The solution is to implement the BIM model--in the form of the standard Industry Foundation Classes (IFCs)--in a database specialized for supporting large, complex data models of engineering projects: a model-server system. The PI has recently received a CFI awards to acquire a model-server test bed for our model-based building and municipal infrastructure research. Using this test bed, the objective of this research is to overcome the technical and organizational challenges to enable full scale BIM interoperability. The particular focus is on three application areas that each extends the traditional scope of BIM technology: integration of project management information; integration of municipal infrastructure management information, and integration of information to support sustainable construction practices. Three PhD students will each interact with industrial partners on full-scale projects to identify the specific work process targets, extend the IFCs as necessary to model the required data, build prototype interfaces between the model-server and the relevant industrial software applications, carry out exhaustive interoperability testing, and prepare the results in the form of best practices following our previously-developed project information management methodologies.
