摘要:随着以BIM、GIS、互联网、物联网、AI、云计算等为代表的新一代信息技术的发展，一个大规模产生、分享、应用数据的DT时代已经来临，建筑企业涉及上下游链条长，产生和汇集的数据量非常丰富，这些数据隐藏着建筑立项、设计、施工、交付、运营等过程的价值规律，是企业的重要资产，建筑业将逐渐进入DT时代，而实现企业数据资产的核心是数字化交付。由于政府和行业尚未制定出数字化交付的具体标准和要求，竣工移交采用的仍然是实体档案为主、电子档案为辅的方式。因此竣工数字化交付是全行业关注的课题，亟需研究探索行之有效的方法与措施，推进数字化交付的实现。本文全面回顾了工程竣工交付产业链参与方及业务特点，总结分析了工程竣工交付业务存在的关键点及痛点问题，定义了工程竣工数字化交付业务范围及交付对象，提出了基于BIM的工程竣工数字化交付方案，并在此基础上研究设计了工程竣工数字化交付系统，解决工程建设过程中业务数据的汇集问题，实现竣工备案、城建档案、运维交付等数字化集成交付，形成工程数据资产，支撑建设方由建设开发向运维服务转型。

Abstract: With the development of a new generation of information technology represented by BIM, GIS, Internet, IoT, AI, cloud computing, etc., an era of large-scale data generation, sharing, and application has arrived. Construction companies involve long upstream and downstream chains, and the amount of data generated and collected is very rich. This data hides the value law of the process of building project approval, design, construction, delivery, and operation. It is also an important asset of an enterprise. The construction industry will gradually enter the DT era and the core of realizing enterprise data assets is digital delivery. Since the government and the industry have not yet formulated specific standards and requirements for digital delivery, the completion and handover still adopts the method of physical files as the main and electronic files as the supplement. Therefore, completed digital delivery is a concerned topic of the entire industry, and it is urgent to study and explore effective methods and measures to promote the realization of digital delivery. This article comprehensively reviews the participants and business characteristics of the project completion and delivery industry chain, summarizes and analyzes the key points and pain points of the project completion and delivery business, defines the scope of the project completion digital delivery business and the delivery object, and proposes the BIM-based project completion digitalization delivery plan. And on this basis, this paper researches and designs a digital delivery system for project completion to solve the problem of collection of business data in the process of project construction, and realizes digital integrated delivery such as completion filing, urban construction archives, operation and maintenance delivery, etc., which will form project data assets to support construction companies to transform from construction and development to operation and maintenance services.
