Quantification and optimisation of Construction Waste (CW) in the design stages are vital to implementing preventive CW management measures. Previous ICT-integrated CW models are not efficiently upscaled to achieve an interoperable and automated workflow. Therefore, this paper presents a BIM-integrated semantic framework for CW quantification and optimisation from the early design stages. A CW data model using Semantic-Web-Technologies (SWT) was developed and integrated with BIM. The results proved that unified data structure, standardised and granular information, established semantic relationships between building material and CW data, and diverse measurement units proposed in the framework facilitate seamless and dynamic information flows between BIM and CW platforms. The research outcomes are critical to improving interoperability and automation across the CW assessment process, enhancing the accuracy and reliability of results, supporting timely and integrated decision-making, and easing communication and collaboration among the supply-chain members. A test-case building demonstrates the application of the framework.

用于建筑垃圾量化和优化的 BIM 集成语义框架


在设计阶段量化和优化建筑废物 （CW） 对于实施预防性 CW 管理措施至关重要。以前的 ICT 集成 CW 模型无法有效地扩展以实现可互操作和自动化的工作流程。因此，本文提出了一个 BIM 集成的语义框架，用于从早期设计阶段开始进行 CW 量化和优化。开发了一个使用 Semantic-Web-Technologies （SWT） 的 CW 数据模型，并与 BIM 集成。结果证明，统一的数据结构、标准化和细化的信息、建筑材料和 CW 数据之间建立的语义关系，以及框架中提出的多样化测量单位，促进了 BIM 和 CW 平台之间的无缝和动态信息流动。研究成果对于提高整个 CW 评估过程的互操作性和自动化、提高结果的准确性和可靠性、支持及时和综合的决策以及简化供应链成员之间的沟通和协作至关重要。测试用例构建演示了框架的应用。
