Digital Basements- Optimizing basement construction using real-time monitoring and digital twins

随着市中心的城市更新变得越来越普遍，旧的建筑正在被取代。在这种情况下，如何处理以前建筑物的旧基础成为设计新上层建筑的挑战。因此，利用现有的基础可以节省大量的财政和环境费用。然而，目前评估基础重用的方法，如案头研究和NDT，有可能增加风险或导致次优设计的局限性。此外，现有基础之上的上部结构的设计是一个复杂的迭代过程，涉及多个利益相关者的相互作用，如建筑师，结构和岩土工程师。该项目旨在为未来的建筑开发一个数字孪生模型，其中地下室/基础和地下结构土壤参数将被实时捕获和监测。这将有助于使一个令人信服的情况下重用的基础上，对飞行寿命监测数据，将流入设计过程。一个优化的传感系统将被设计为有效的系统识别后，确定需要从不同利益相关者的角度捕获的参数。将开发一个基于计算BIM的工作流程，在3D模型、结构和岩土有限元模型之间建立紧密联系，以根据设计和可施工性约束产生设计输出。该工作流程将在一个候选建筑项目上进行测试。

Older structures are being replaced as inner-city urban renewal becomes more common. In such cases, the question ofwhat to do with the old foundations of previous buildings becomes a challenge for designing new superstructures. Thereuse of existing foundations results in significant financial and environmental savings. However, current methods forassessing foundation reuse, such as desk studies and NDTs, have limitations that may increase risk or result insuboptimal designs. Furthermore, the design of the superstructure above the existing foundation is a complex anditerative process involving the interaction of multiple stakeholders, such as architects, structural and geotechnicalengineers. This project aims to develop a Digital twin for future construction where the basement/foundations and thenear-structure soil parameters will be captured and monitored in real-time. This will help make a convincing case forreuse based on the on-the-fly lifetime monitored data that will flow into the design process. An optimized sensing systemwill be designed for effective system identification after identifying the parameters that need to be captured from theperspective of various stakeholders. A computational-BIM-based workflow will be developed, with autonomousconnections between the 3D model, structural and geotechnical FEM models to produce design outputs based on designand constructability constraints. The workflow will be tested on a candidate construction project.
