nowadays, from the construction of a project, the operation of a road, to the operation and management of a city, all can be clearly understood and flexibly dispatched through the establishment of an information model system, creating smart projects, smart transportation, and even smart cities. on september 23, the engineering digitalization conference, hosted by china academy of building research co., ltd. and other units, and specially supported by the ministry of housing and urban-rural development information center and other units, opened in beijing. it is reported that this conference is themed "practice national strategy and build an independent ecosystem", focusing on "digital design", "digital power", "smart transportation", "development ecology" and other fields. during the event, more than a thousand industry experts will share the most cutting-edge scientific and technological achievements in the industry.

"digitalization of engineering construction is the premise and foundation for realizing the industrialization, digitalization and green development of the construction industry, and is an inevitable requirement for the high-quality development of the construction industry." at the plenary session of the engineering digitalization conference, yang jinfeng, a first-level inspector of the engineering quality and safety supervision department of the ministry of housing and urban-rural development, stated that engineering software represented by building information modeling (bim) software is an important support for the digitalization of the construction industry, especially the independent and controllable key control software, which is directly related to the industrial chain security, digital security and even national security in my country's engineering construction field.

the reporter noticed that in recent years bim software has been widely used in various engineering construction processes, especially for public buildings with special shapes and complex structures. bim software is playing an important role that cannot be ignored. it has transformed the empirical construction that required manual "feeling the stones while crossing the river" in the past into a visual advance simulation construction, making on-site construction more accurate.

"the research and development and application of key engineering software in our country have achieved a breakthrough from 0 to 1 and are accelerating development," said yang jinfeng.

in addition, a number of digital technologies based on information models are moving towards serving the entire city.

in 2012, the ministry of housing and urban-rural development proposed the construction of smart cities in china, requiring all regions to improve their urban management capabilities and service levels. "after more than ten years of exploration and innovation, many achievements have effectively supported the needs of smart urbanization." yu jing, director of the information center of the ministry of housing and urban-rural development, said. building information models are evolving into city information models (cim), providing support for the construction of smart cities.

cim refers to the establishment of a multi-source data model of the city's physical space and its various types of information based on a three-dimensional data model and supported by technologies such as geographic information systems and building information models, thereby forming data assets of the city's physical space and optimizing urban management.

once a city applies cim, it means that the city has a smart "brain". from high-rise buildings to parks and green spaces, from traffic flow to environmental data, with it, relevant departments can plan industrial parks more accurately to make industrial development more reasonable; they can timely discover ecological risks and protect green homes; they can also achieve more refined urban management and make urban operations more efficient.

looking to the future, yang jinfeng said that all regions should continue to expand the application scenarios of digital engineering software and accelerate the iteration and upgrading of core technologies. "good software is not written, but used." he said that my country is the country with the highest quality of engineering construction in the world, which provides a wealth of application scenarios for engineering software applications. in actual projects, we should give priority to the use of self-controlled software and continuously optimize the core competitiveness of my country's engineering software through engineering practice.
