The application of BIM technology in engineering supervision?

Currently, BIM has developed into an important technical support for supervisors in the construction industry to carry out their work efficiently. The article for engineering supervision BIM in the construction process involved in the various stages, the implementation of the application of the application point and application methods to carry out in-depth research and analysis work. Summarize and summarize the existing problems, and give effective solutions to countermeasures, so as to be able to achieve the purpose of constantly improving the role of supervision units to apply the effect of BIM, for the supervision industry as a whole to provide better and faster development of feasible suggestions.

1BIM in the supervision industry in the application of value

bim technology as a new technology by a lot of professional attention, especially in the construction industry in the role played by BIM has achieved greater results. Through the current overall development of China's construction industry, BIM technology will be more in-depth analysis and research by domestic professionals in the future development process. Its application value will be further explored.

2 Engineering Supervision BIM Application Points and Application Methods

2.1 Improve Supervision Dynamic Integration and Informatization Management

Currently, the biggest difficulty in the execution of the supervision work is that it is not possible to do a comprehensive management and control of the entire implementation process. However, BIM is able to reflect the progress of building construction through the 3D model form, and can also integrate the construction site layout and material resources and other related information, to build a modern nD construction information model. Thus, the construction of the entire project in all periods of time and the work involved in the dynamic integration, information management.

2.2 Strengthen the coordination and harmonization of supervision and construction parties

Harmonization and coordination of the relationship between the construction parties is an indispensable part of the work of the supervision, and the application of BIM can to a large extent meet the demand for all kinds of information from all parties of the project construction **** enjoyment, mutual integration and interoperability purposes. Construction parties in the effective support of BIM technology, to achieve the project progress, quality standards, safety requirements, resource allocation and other work comprehensive control.

2.3 Completion of virtual construction, improve the supervision of pre-control work

In the support of Internet technology to realize the virtual construction of the project in the actual construction process of the various problems faced to do in advance to judge. At the same time, the supervisory body can also use this virtual model to understand the construction process in advance, to improve the supervision and pre-control work.

2.4 Improve the application of BIM supervision unit of the work

In the construction industry engineering construction, supervision unit is based on the owner's requirements, the construction process to ensure comprehensive safety and meet the standard quality of real-time management. BIM technology in the application of the domestic relative limitations, the majority of owners of the effective role of the role of its is not a very good understanding. Therefore, the supervision unit should do a good job in advance of the BIM model design, use and other aspects of the work, and also assume the responsibility of organizing the construction parties *** with the participation of the construction of the BIM model construction and other related work, and for the parties to put forward proposals or requirements for timely improvement of the BIM model, but also according to the construction of the parties to the BIM use of the problem of the situation to give effective solutions to the countermeasures.

3BIM technology in the supervision of the practice of the application of examples

3.1 design documents review

When in the structural design of the building construction period, due to the CAD 2D drawings there are certain defects, resulting in structural data on the building external style of the building caused by a certain degree of interference can not be detected in a timely manner. At this time, the supervisory party should have a good level of pre-control, to do a good job on the drawings of the research work, in advance to find the problem and give timely correction. For example, a project ladder section net height does not comply with the relevant provisions of the general floor sorghum and staircase ladder section were designed in two different drawings, such as if not field measurements are difficult to find problems through the drawings. Therefore, in order to avoid delays due to drawing problems, the supervisory party to build a BIM model in advance, in advance to understand the entire construction process, for the discovery of the problem should be reported in a timely manner level by level, and ultimately arrive at the purpose of correcting the problem.

3.2 Quality control of special nodes

According to the BIM model, the supervisory party can carry out simulation quality control of special nodes, and do a good job in advance of the technical understanding of all parties to the construction and construction procedures. Through the BIM has the visualization function, build a 3D three-dimensional physical graphics in the form of scenario reproduction play to the technical staff, at the same time on each step one by one explanation, for special nodes focus on the explanation, enhance the staff's understanding of this area, so that can to a certain extent not only reduces the workload, but also in accordance with the standard quasi-requirements to do a good job on the special nodes of the quality control work. For example, the number of windows on the side of high-rise buildings is more than 20, and there are different sizes, irregular nodes and other characteristics. Supervisors through the BIM model to understand the drawings in advance, and then the relevant staff to carry out technical briefing work, in accordance with the model requirements checking, a good implementation of the special nodes in accordance with the requirements of the construction of the drawings, by the designer's high praise.

3.3 Prevention of quality control problems

In the construction process of the project, to do a good job of preventing quality control problems for the supervisory side is a high standard and high requirements. The building reinforcement sorghum cross part elevation is generally difficult to meet the requirements, not easy to be controlled, it is easy to cause the protective layer is relatively thin, steel exposed and some other quality problems. Supervisors according to BIM technology in advance rehearsal rebar sorghum cross part installation, strictly follow the drawing set design standard reasonable installation of each rebar, especially rehearsal elevation surface parts, very good completion of the technical requirements. According to BIM to do a good job of preventing quality control problems for the supervision side has a very important significance, need to pay great attention to.

3.4 Improvement of electromechanical pipelines

According to the supervisory staff in the floor of the sprinkler line BIM modeling that the sprinkler line is perpendicular to the frame beams, and was up and down the direction of the foldback, modeling and construction time consumes a huge amount of time. At this time, the supervisory party proposed to change the sprinkler line from up and down to vertical installation, and again modeling demonstration, and finally won the approval of all parties to be adopted. This change greatly shortens the construction time, reduces the cost, ensures the construction progress of the orderly progress, the results are remarkable.

3.5 Root auxiliary supervision site acceptance

In the whole engineering construction quality control work process, supervision of key processes control and acceptance work accounted for the vast majority. Supervision engineers with technical level can fully understand the construction drawings with the help of BIM modeling, master each control focus; in the drawing review and supervision of the work, and construction personnel communication, will be fully proposed acceptance requirements, so that they are familiar with; in the acceptance of the work, with the help of the relevant testing instruments in accordance with the BIM model, can further assist in improving the quality of acceptance work, for the emergence of prominent Problems should be provided with BIM provisions of supervision engineers rectification opinion letter, further enhance the technical level of supervision personnel, greatly reducing the later communication workload, saving time. For example, curtain wall construction trailing board installation acceptance work, view drawings is difficult to understand its frame structure, coupled with more frequent rotation of supervisory personnel, the cognition of the drawings is very effective, at this time according to the BIM technology to assist supervisory personnel in accordance with the model requirements of each installation node acceptance, able to look directly at the existence of the problem, and at the scene of the installation of personnel to provide guidance to rectify the problem in a timely manner, to avoid the occurrence of safety accidents.

4 Conclusion

According to the above description, it can be learned that the BIM technology specialization requirements are high, however, in the actual supervision of the work involved in all aspects of technology is very broad, so the supervisors should be fully combined with their own technical ability to determine the standard of work. In terms of the current project construction supervision, supervision personnel in the BIM technology management level needs to be further improved, so we need to strengthen the BIM technology related management work, with the owners to do a good job in the supervision work, the role of BIM to give full play to the quality of the project supervision process.
