by There are four most famous masters of modern architecture, Zaha Hadid, I.M.
Pei, Le Corbusier and Tadao Ando, commonly known as “F4 in architecture”.
The famous Corbusier once mentioned in his first book towards new architecture that his inspiration for understanding new architecture comes from cars.
According to him, in addition to bringing more economical and efficient construction, architectural industrialization will also lay a foundation for improving architectural aesthetics, just as modern automobile chassis supports the innovation and design of automobile body.
However, compared with the earth shaking development of the automobile industry, the traditional construction industry is obviously much slower.
The good news is that this is changing little by little.
In recent years, the construction industry has begun to pay attention to efficiency, sustainable development and avoiding the use of non renewable fuel resources, as well as the increasing demand for new buildings and new infrastructure.
The traditional industry has opened the road of transformation and introduced many new technologies, including the migration of some technologies already applied in other industries.
In addition, in order to meet the concept of sustainable development, wood, a renewable material, has also been selected as an ideal building material, especially under the background of some new technologies and methods.
For example, innovative large-scale production of wood components – Cross composite wood (CLT) and glued wood; New design methods and processes – BIM (building information model) and DFMA (product design for manufacturing and assembly); Visualization tool – VDC (virtual design and construction); Production tools – CNC (computer numerical control) and so on.
DFMA (manufacturing and assembly design) is actually a design concept, which refers to the perfect combination of manufacturing oriented design and assembly oriented design in the product design stage, fully considering the requirements from manufacturing and assembly, so as to make the product have good manufacturability and assembly, so as to avoid manufacturing and assembly quality problems in the later stage of product development.
DFMA is widely used in many industries.
In engineering construction, because the construction is different from the traditional method when using a large amount of wood for design and construction, it is more assembled with wood components, so it is especially suitable for large-scale production of wood components, such as cross laminated wood or glued laminated wood.
Large boards, beams and columns are manufactured off-site and then transported to the construction site.
All modules and holes are prefabricated to be inserted into the predetermined installation position, including MEP (mechanical, electrical and piping).
In order to ensure the smooth progress of the whole process from the beginning to the end, organize various partners to participate in the product manufacturing at the beginning of the project, so as to avoid delay and rework at the construction site.
Collaboration is critical, and that’s why BIM is important throughout the process.
BIM refers to a set of technologies, processes and policies, which can enable all partners of the project to jointly design, build and operate in the virtual space, throughout the whole life cycle of the project.
In short, if you want any construction project to be carried out efficiently, it is important for everyone to speak the same language – BIM.
It can carry out visual simulation and virtual construction for all parts of the project, so that participants can easily understand the feasibility and assembly of the solution.
In addition, BIM can present the design scheme in the form of three-dimensional model, which is conducive to the cooperation between project teams and eliminates the risk of common errors when using traditional two-dimensional drawings.
These models can also be further imported into several other related structural and thermal analysis software, or used in the data files of CNC machine tools.
It is observed that the use of Bim in the design phase can reduce the time required to convert architectural drawings into manufacturing drawings and improve the coordination and interaction between the design team and the external manufacturing team, which is very important for the smooth progress of construction.
If we look back to Asia, Singapore, Japan and South Korea are all leading countries in BIM Technology.
Their development path in this field is similar – vigorously promoted by government departments, supported by enterprises and high efficiency.
China has also adopted the same approach.
In the 16 years since the introduction of BIM Technology in 2005, China’s BIM Technology has made considerable progress.
Especially in the past few years, the policy support of government departments makes the promotion and popularization of Bim in China imperative.
It is understood that this is closely related to China’s rapid urbanization process and huge construction volume, the increasing attention of the construction industry to sustainable development, the increasingly fierce industry competition in building life cycle and intelligent operation and maintenance energy efficiency analysis, and the requirements of China’s national policies.
China’s Ministry of housing and urban rural development announced the launch of the preparation of China’s construction industry informatization development report (2021), which once again spoke for BIM — emphasizing the vigorous development of digital design, intelligent production and intelligent construction, and accelerating the development and application of building information model (BIM) technology.
Use Bim and VDC technology to realize 70 day high-rise buildings from the ground! In the complex project of Brock Commons tallwood building on the 18th floor of the University of British Columbia, VDC is deeply used to support the analysis of design and construction.
BIM also describes the attributes of each different architectural element and creates a virtual project prototype that can simulate and test performance.
VDC is a sub content of BIM, which mainly focuses on geometric 3D display of installation link.
It facilitates the planning and communication of all stages and aspects of the end-to-end design and construction process because it provides an accurate and detailed demonstration model reflecting the whole construction process.
In this project, the VDC model has been established from the beginning of the project, including all structural elements, interior decoration and MEP system, as well as various details and auxiliary facilities in the construction process..
