Tongyan Information No. 20221004 | BIM parameter optimization special-shaped steel bar application case

With the development of architectural design and construction technology, special-shaped buildings emerge in an endless stream。They are irregular surfaces on the overall surface, which shows a special spatial effect and has a strong visual impact。Alien architecture breaks the rule that inner function is inseparable from outer form。When the form of the building is more free, its function is more varied, and the space of the building is endowed with more possibilities and creativity。The uncertainty of anomalous architecture is impossible to achieve with traditional architectural design techniques。The floor can be deformed, and the walls are no longer straight, but have a perfect arc。It is this freedom and variety that makes the alien building more strongly express emotion than the regular traditional building。

Tongyan Information No. 20220901 | A brief discussion on the application of digital twin in construction safety scenes

With the acceleration of the new digital era, digital twins have been widely used in smart cities, smart buildings, smart manufacturing, smart factories and other fields。The concept of digital twins was proposed in 1992, officially named in 2002, and in 2012 Glaessgen and Stargel gave an academic definition of digital twins。It is defined as the use of physics engine, multi-physical, multi-scale probabilistic simulation integrated by the system, mapping in virtual space, and updating sensor data and historical data to reflect the real characteristics of the whole life cycle of the entity corresponding to the model。

Tongyan Information 20220801 | domestic BIM standard summary

2005年，The concept of BIM has been gradually recognized by the Chinese people due to the promotion software of Autodesk,But not until 2016,The Ministry of Housing and Urban-Rural Development issued the "2016-2020 Informatization Development Outline for the Construction Industry" clearly states that the "13th Five-Year Plan" period,We will comprehensively raise the informatization level of the construction industry，Focus on BIM",BIM is really getting the attention of the industry,Mushrooming and blossoming everywhere。Correspondingly, the state and local governments have successively issued a number of BIM specifications, standards, technical guidelines, etc., gradually establishing and improving the BIM standard system, escorting the healthy and standardized development of BIM, and gradually realizing the "use basis and assessment standard".。

Tongyan Information No. 20220702 | The first data storage standard based on IFC in China -- Interpretation of Shenzhen Building Information Model Data Storage Standard

On May 25, 2022, Shenzhen Housing and Construction Bureau officially released Shenzhen's "Building Information Model Data Storage Standard" SJG114-2022，This standard is the first local BIM data standard in China based on the international IFC data format，The technical route of BIM construction, archiving and application is given as "Shenzhen solution".It is of great significance for the full implementation, in-depth application, data opening and new smart city construction of BIM technology in Shenzhen。

Tongyan Information No. 20220602 | On the application of BIM technology in water conservancy projects
