基于数字孪生的建筑工程交付模型建立及应用研究OA北大核心CSTPCD

Building lifecycle data contains valuable information about the processes of project initiation,design,construction,operation,and maintenance,which are important data assets.At present,there is no unified digital delivery standard in the construction industry,and there are issues of insufficient integrity and low utilization of construction delivery data.In order to better deliver and utilize building information,the difficult issues in current digital delivery were comprehensively analyzed,the data characteristics and delivery objects generated in each stage of construction project were summarized,the data elements that need to be delivered were defined,and a digital delivery model for construction engineering was proposed.This model was driven by the digital twin framework.In the process of building the data model,the spatiotemporal evolution laws and the virtual real interaction mechanism were introduced,and the integration of multi-dimensional and multi-scale building data was studied.Based on actual engineering cases and platform as carriers,the operational process of the delivery model and its functional application in engineering were studied.The research results indicate that the digital delivery model can effectively complete the process of building data collection,transmission,and final utilization.The model simplifies the delivery steps of relevant parties,and ensures integrity,timeliness,and authenticity of the delivered data.The delivered data can be shared and utilized by participants through the platform to improve data utilization.
