Although BIM has been widely used in the design, construction , and management stages in construction and construction, some problems have been exposed in the process of applying BIM technology! Today let’s talk about what problems exist in the application of BIM technology?
1. There are irregularities in the construction process according to the drawings. Although the application of BIM technology can fully display the design intent and construction progress, in the actual implementation process, due to insufficient supervision, construction operators may cause quality problems in certain construction procedures, key construction links or important quality nodes. Defects or problems affecting sensory quality.
2. Talent resources skilled in using BIM technology are scarce. Although BIM technology is applied in various fields of the building life cycle, the utilization rate of BIM technology in the whole industry is low. Especially in the construction unit, the construction unit, as the key link of the physical construction of the design drawing model, is a practitioner in the application of BIM technology, but because most technicians themselves do not have enough BIM Theoretical knowledge, and the application of BIM technology is not paid much attention within the unit, which leads to a serious shortage of BIM technical talents.
3. The versatility of the BIM model is low, and the single structure model has the characteristics of singleness in the project , and the secondary utilization rate is low. Due to the large amount of parametric information attached to the BIM model , but in the building life cycle, because it involves many links such as design, negotiation change, budget, and operation management, the calling of model parameter information is repetitive, resulting in information redundancy .
4. The establishment of a high-precision BIM model is inseparable from the establishment of the model’s elments, but as far as the current BIM software is concerned, the main problem is that the family library is still not large enough. The family in Revit is a major bottleneck restricting the development of BIM worldwide . Although family library resources are already available on the network platform, the establishment of the family model needs to be determined according to the actual engineering situation, and the family model on the network has limited applicability and lacks the size, energy consumption, material and other information of the family model, so BIM The accuracy of the model cannot be effectively guaranteed.
5. The establishment of the BIM model is based on various mathematical logics for physical connection. If a professional condensate pipe is not accurately connected to the equipment or the variable diameter elbow, collision detection will occur in the later stage of the model. Error problem. If the above-mentioned model is used for cost management, it will lead to errors in the entire profession and even the total budget, while the BIM model lacks the error reporting function.
6. Traditional design and BIM design coexist. Since the BIM model is established mainly on the basis of CAD drawings at this stage, errors will inevitably appear in CAD drawings, so designers not only need to correct the mistakes, but also need to consult drawings and atlases repeatedly , thus causing designer’s frustration The workload is too large, and there are also cases of repeated operations. Therefore, the transformation of the design method is also an issue that needs to be considered today.
7. The standards and specifications of BIM models need to be unified. Although the country has issued some standards for BIM technology, the refined management of construction enterprises is still far from enough, and there are many types of domestic BIM software, it is necessary to establish a unified BIM format and standard, so that design, construction, construction units Unified management of BIM models.
8. BIM models and various technologies, such as: VR, AR, Digital-twin, etc., still need to rely on third-party plug-ins or software to realize the data docking issue, thus causing certain obstacles to the data flow of BIM. After data docking A second inspection is also required. Therefore, the interface problem of BIM technology still needs to be continuously improved.
