From primary school, junior high school, high school to university and even work, everyone has written papers, which can promote experience and exchange understanding. I believe many people will find it difficult to write papers. The following is the application paper of BIM technology in engineering cost calculation software that I collected for you, hoping to help you.

BIM technology is an organic combination of digital technology and intelligent management. Integrating BIM technology into project cost can promote the development and breakthrough in the field of project cost. In the actual operation process, the effective application of BIM technology can improve the efficiency and quality of construction cost. However, there are still many problems, which affect the popularization of BIM technology in construction project cost calculation software. This paper mainly studies the characteristics and advantages of BIM technology, and deeply discusses its application in construction project cost calculation software.

In 1970s, BIM technology was first applied to a certain field in the United States. After a long period of improvement and optimization, building information model technology has gradually developed into a new technology. Through relevant investigation, it is found that this technology is widely used in engineering design and construction management, and information fusion can be carried out by combining this technology with parametric model. In addition, in the process of project planning, construction, actual operation and maintenance, BIM can play the role of data sharing and information transmission, so as to ensure that relevant staff have a correct understanding and understanding of building information and make rational use of this information.

1 and BIM technology overview

BIM technology plays an outstanding role in the fields of architectural engineering and civil engineering, and is a new research tool in these engineering fields. As early as 2002, the concept of BIM appeared and was favored by many fields around the world. This technology can realize the integration of building information and can run through all aspects of building engineering. From the initial design to the final end of the project, BIM can effectively integrate the information of all links, and then feed back the integrated information to the design team, the construction unit and the facility operation department, so that its relevant staff can fully grasp and use the data information.

2. Integrated analysis of 2.BIM technology

According to the analysis of the new design form at present, civil engineering has high requirements for all links and steps in the design, and the design work needs to be effectively combined with the subsequent construction control. In this case, it is an important content to manage and analyze various forms of data and integrate them accordingly. If you want to improve the engineering design reasonably from the aspect of stability, you need to make full use of BIM technology according to relevant data and processing points, and then build BIM.

3. Application advantages of 3.BIM technology in engineering cost calculation software.

Construction engineering information simulation technology can achieve good results in engineering cost, reduce engineering cost and optimize construction site. First, with the rapid development of science and technology, the construction engineering information model has developed into a relatively perfect five-dimensional model. In practice, the staff can operate the planned maintenance mode according to the related technologies, thus improving the overall statistical work efficiency. In addition, when the technology is perfected to a certain stage, the cost demand can be analyzed at the same time, with high work efficiency and high accuracy of the obtained data. Secondly, it is analyzed from the perspective of optimizing the construction site, because the workload of the whole project is large. If we can manage it with the help of information simulation technology of construction engineering, we can optimize and organize the construction site efficiently, which will help to ensure the smooth development of construction work and reduce the loss of building materials.

4. Application of 4.BIM technology in engineering cost calculation software.

4. 1 Realization of whole process cost management

The application of BIM technology in the fine cost management of construction projects can not only solve the problem of separation of specialties and stages, but also enable cost engineers, builders, architects, engineers and owners to work together at all stages, and also open a new chapter in project cost management. Make project decisions after the completion of design, bidding, completion, completion acceptance and completion acceptance. After the project is put into production, dynamic cost control can effectively connect all links in the construction process and effectively control the total construction cost, thus improving the construction efficiency.

4.2 Cost data accumulation and * * *

BIM building information model provides all the information actually existing in buildings, including geometric information, physical information and regulatory information. BIM can form a unified organic whole of all information and avoid the loss of changes in information transmission. Because the project enjoys the same model in the whole life cycle, all data collection and changes are carried out on this model, and all these data are only exported, which can protect the integrity of the data.

4.3 BIM simulation decision-making of the project

In the stage of project investment decision-making, the cost data of completed projects can be called, which are similar to those of proposed projects, such as the price of human resources and the cost per square meter in this respect, which can estimate the total investment of proposed projects efficiently and accurately and provide accurate basis for investment decision-making. The design determines the construction and installation costs, associates the project components in the design drawings with the cost information accumulated in the database, and outputs relevant cost information according to sub-projects, so as to limit the design and reduce the project cost. After determining the design basis of the general contractor and the drawing review stage, BIM can integrate all disciplines into a unified platform. Design contractors can review drawings from different angles, and use the visual simulation function of BIM to simulate collision inspection, which can find unreasonable time points in time, reduce design errors, greatly reduce rework costs and reduce possible disputes during project implementation.

4.4 BIM comparison of different dimensions

The comparison of multiple calculations in cost management is very important for finding problems in time, correcting them and reducing the project cost. Multi-calculation comparison usually analyzes and compares from three dimensions: time, process and space. It can not only analyze the cost of a time period, but also divide the actual cost of the project into various processes, and statistically analyze the relevant cost elements according to the spatial region. Starting from these three dimensions, it is necessary to divide and summarize a large number of physical consumption and cost data, and use BIM software to compare and calculate multiple dimensions quickly and accurately. In addition, with the support of the database, the statistical decomposition and analysis of any conditions can be realized in the least time, which ensures the efficiency and accuracy of multi-dimensional cost analysis.

5. Strengthen the application strategy of BIM technology in engineering cost calculation software.

5. 1 Increase the investment in the technical basis of information model of construction engineering.

With the help of the power of building engineering information simulation technology, the project cost goal can be achieved faster and with higher quality. In practice, in order to make full use of relevant technologies, staff should choose reasonable software types and management modes in infrastructure construction according to the specific conditions of the project, so as to give full play to the role of technology. At present, the construction engineering information simulation technology has been actively promoted and operated. For cost consulting enterprises, it can improve the efficiency and level of engineering cost calculation software services, but it also needs the basic investment of relevant technicians.

5.2 Strengthen the training of information model technicians in construction engineering.

In terms of personnel training, we should start with the selection, especially those with comprehensive quality and strong ability, so that they can quickly understand the information simulation technology of construction engineering. Moreover, in the process of talent training, in addition to the basic skills that talents need to master, they also need to be trained in their management awareness and ability. Relevant leaders need to do a good job in personnel education and technical publicity when establishing the awareness of project cost informatization, and mobilize employees to actively learn and apply technology.

5.3 Reasonable monitoring of the overall cost of the project

In order to ensure the accuracy of engineering calculation results, in the actual monitoring process, the staff must ensure that the overall cost of the project is reasonably monitored, and use the visibility of BIM technology to effectively summarize the data of all links in the project. Especially for some large-scale construction projects, different operation links need to be carried out during the construction period, and the number of sub-projects is very large, but the budget process is highly complicated. In order to ensure the accuracy of the final budget results, budget personnel need to do a good job in the specific budget work according to the characteristics, procedures and contents of sub-projects of specific building structures during the construction process. In the completion settlement, if there is a budget problem, it is necessary to put forward the corresponding solution. In short, in order to ensure the building information model technology, play its due value in the engineering cost calculation software, and promote the effect budget of the whole project cost, personnel must fully combine the specific operation of the project, carry out reasonable control operation on the project cost, and fully understand the characteristics of the building structure by using the visibility of the building information model.

In addition, in the budget work, the budget staff must improve the risk awareness, strengthen the inspection frequency in their daily work, improve the timeliness of problem discovery in construction projects, and formulate scientific and reasonable risk prevention measures to ensure that the risks in construction projects can be well controlled. Because there are many kinds of equipment involved in the construction process of building projects, scientific and reasonable budget software should be selected in the calculation work in full combination with the overall economic benefits of building projects, so as to give full play to the use value of the software, ensure the quality of building projects and control them within relevant standards.

6. Concluding remarks

In the field of architecture, no matter which business entity wants to manage the project comprehensively, it is important to improve the construction technology, but at the same time, the management of each link cannot be ignored. At present, most engineering construction teams have invested a lot of energy in cost work, but manual management has lost its superiority, and complex cost management cannot be reasonably controlled. Therefore, based on the application of computing software, the application value of BIM technology is fully exerted. Through the tracking management of cost, it is expected to improve the overall level of the project and avoid obstacles and interference caused by cost changes.
