摘要:由北京城建集团承建的马尔代夫维拉纳国际机场改扩建工程项目，具有工期紧、质量要求高、现有机场不停航、填海工程沉降风险、海外工程人员难沟通等特点，为保障工程如期完工，北京城建集团马尔代夫机场改扩建项目采用了由北京麦格天宝科技股份有限公司提供的基于BIM的数字化施工新技术，使用BIM技术进行建模，并在施工过程中以BIM模型进行引导，以数字化施工技术进行过程质量控制，与传统施工方式相比，人员减少41%~73%，工效提升了20%~50%，工期缩短了20%~50%，提升了项目管理水平，真正做到了“减员增效，科技创新”。本文将主要介绍基于BIM的数字化施工新技术在马代机场项目中的应用，希望为今后的类似项目提供参考。

Abstract: The reconstruction and extension project of Velana International Airport in Maldives is contracted by Beijing Urban Construction Group, possessing many characteristic of tight construction period, high quality requirements, non-stop of existing airports, risks in settlement of reclamation engineering, and difficulty in communication with foreign co-workers.To ensure the completion of the project on schedule, the contractor applies the new BIM-based digital construction technology in Maldives Airport renovation and expansion project, which is provided by Beijing MAG Science & Technology Co., Ltd. Through the BIM modeling and adopting the BIM model to guide the construction process, the quality control during the construction period is completed by digital construction technology.Compared with the traditional construction method, the staff is reduced by 41%~73%, the work efficiency is increased by 20%~50%, and the construction period is shortened by 20%~50%.The project management level is indeed improved, truly achieving the goal of "staff reduction and efficiency increase, scientific and technological innovation".The application of BIM-based digital construction technology in airport project in Maldives introduced in this paper will provide reference for similar projects in the future.
