Operational risk assessment and decision support in a 4D simulation using building information modeling

越来越明显的是，由于不断变化的危险，以及建筑设计的严格要求和不断增加的复杂性，建筑物正面临越来越大的风险。由于不同类型的建筑系统之间的紧密耦合，故障可能会在建筑物及其操作中级联。这种状态将受益于工程设计过程中风险评估的综合方法，该方法可以建模和描述级联效应。完成这项研究以应对这一挑战的计划通过四个模块完成，这些模块旨在研究新工作流程的潜力，以增强建筑设计工作和支持工作流程的新方法。模块一涉及创建现有建筑物的3D扫描的实验，模块二涉及转换建筑信息模型（BIM）。结合起来，这些模块是关于确定如何产生建筑物的合适数据来对级联风险进行建模，并且可能包括使用有关建筑物或其运营的其他信息进行增强，例如建筑物的状况评估或其他模拟（例如，结构化）以产生可以填充风险参数的工作流。模块三是创建一个自定义的VR模拟，从其他模块中获取数据，并允许客户体验跨建筑组件的危险影响的级联。最后一个组成部分是在模拟平台中创建一个风险评估和决策支持系统，该系统将级联风险计算与模拟中的建筑信息相结合，以支持工程设计。加拿大通过创造创新的工程和技术受益，通过为我们的工程师提供新的能力，进一步提升加拿大作为世界领导者的地位。此外，在国内应用该能力可以减少加拿大建筑物的风险。

It is increasingly evident that buildings are facing mounting risks due to the ever-changing hazards, and thetightening requirements and expanding complexity of building designs. Due to the tight coupling betweenbuilding systems of different types, failures can cascade across a building and its operation. This state wouldbenefit from an integrated approach to risk assessment in the engineering design process that can model anddepict cascade effects.Completion of the research to meet this challenge is planned through four modules intended to study thepotential of a new workflow to augment building design efforts and a new method to support the workflow.Module one concerns experimenting with creating a 3D scan of existing buildings and Module two concernsconverting these into Building Information Models (BIM). Combined, these modules are about determininghow suitable data can be produced of a building to model cascading risk and may include augmentation withother information about the building or its operation such as condition assessments or other simulations of thebuilding (e.g., structural) to produce a workflow that can populate risk parameters. Module three is the creationof a custom VR simulation that ingests the data from the other modules and allows clients to experience thecascade of hazard effects across building components. The final component is the creation of a risk assessmentand decision support system within the simulation platform that incorporates a cascading risk computation inconcert with the building information in the simulation to support engineering design.Canada benefits through the creation of innovative engineering and technology, further advancing Canada'sposition as a world leader by providing our engineers with new capability. Further, application of the capabilitydomestically can serve to reduce the risk to Canadian buildings.
