1 model: a building information model and a multidimensional (n-3D) structured engineering database (digital engineering model).
Two objects: The information in the BIM model describes two objects: engineering entity and process business.
Three core competencies:
1) to form a multidimensional (n-3D) structured engineering database;
2) Data granularity can reach component level or even smaller, such as a steel bar and a brick;
3) Engineering Big Data Platform: It carries a huge amount of engineering and business data, and its multi-dimensional structural ability makes the computing ability of engineering data and information extraordinary, which is far from being compared with previous engineering management techniques.
Four values: BIM technology provides for project management and enterprise management;
1) Powerful computing power: real-time processing ability of engineering big data;
2) Real-time collaboration ability: far beyond the collaborative technology of project management;
3) Realizing virtual construction: greatly narrowing the gap with the manufacturing industry, making the construction industry begin to have the "prototype" engineering capability similar to the manufacturing industry;
4) Engineering and business information integration: make engineering and business data an organic whole.
Five stages: the application of BIM is divided into five stages:
1) scheme decision, 2) planning and design, 3) construction, 4) operation and maintenance management, and 5) renovation and demolition.
BIM can play an important role in five stages, and each stage will have a large number (even hundreds) of applications.
More and more work and assignments will be completed on the platform based on BIM, thus improving the work efficiency and quality, and making the work results storable, retrievable, computable and collaborative. BIM will eventually become an operating system (OS) in the construction industry.
Six applications: In the construction stage, BIM technology will realize hundreds of applications, but the following six applications have the greatest impact on project management:
1) engineering quantity calculation, cost analysis and resource planning;
2) Collision inspection and deepening design;
3) Visualization and virtual construction;
4) Collaborative management;
5) Integration of engineering files and information;
6) Basic database of enterprise-level projects.
Seven dimensions: BIM has three dimensions (space, time and process) and seven sub-dimensions (3D entity, 1D time, 3D process-bidding process BBS, enterprise quota process EBS and project progress process WBS).
The above content comes from the book BIM Changing the Construction Industry by Dr. Yang Baoming, Luban Software.
Simply put, bim is building information modeling, the most important of which is "I" information. Bim is different from 2D cad which is widely used now. It is 3D or more, and the construction is guided by 3D model. I hope I can bring you some gains.
