Frame design of the BIM based budget software of nuclear power projects

Abstract

With the continuous update and iteration of Internet information technology, the application of BIM (Building Information Modeling) technology in the fields of project management, cost and construction is becoming more and more popular. The field of project cost relies on the significant advantages of BIM technology to realize the intelligence of project cost management. It can effectively promote the horizontal information collection and vertical information interaction of different participants, and achieve a good information exchange and interaction effect. This paper combines the characteristics of China nuclear power engineering projects, applies building information modeling (BIM) technology, and integrates it into the nuclear power engineering cost software framework. This paper firstly analyzes the basic characteristics of China nuclear power engineering cost software, and puts forward the key functional requirements for existing cost software. On this basis, the basic characteristics of foreign mainstream construction cost software with BIM technology and the feasibility of its application in China is also analyzed. The model consists of two parts, namely the BIM data management platform and the functional model of the construction project budget subsystem. Among them, the BIM data management platform realizes the analysis, storage and management of IFC (Industry Foundation Class) data, and provides a user interface for specific professional fields, such as the field of construction engineering budget, while the construction engineering budget subsystem provides users with cost budgeting expertise. In addition, this paper describes in detail the method of using BIM technology to create the most used pipe network model in cost assessment. Based on Revit software, combined with the use of visual programming tools Dynamo and Revit API, the repetitive and tedious manual modeling process is automated to compete the creation of the BIM model of a large number of pipe networks in a relatively short time, and make the model carry rich engineering information. This paper establishes a basic framework suitable for China nuclear power engineering cost software, which can lay the foundation for the subsequent development of corresponding software. The pipeline network BIM establishment method proposed in this paper can greatly improve the work efficiency of traditional CAD modeling, realize seamless connection with cost assessment, and has broad engineering application prospects.
