Research on Transmission and Transformation Engineering Cost System Based on BIM 3D Modelling Technology

Taking the concept of service-oriented design as the concept, the paper designs the digital platform architecture based on the integrated application ideas and technical methods of the IFC standard and the three-dimensional geospatial engineering cost information platform, and builds a 3DGIS+BIM digital power engineering cost based on the B/S network architecture. information platform. Combined with the application value of BIM technology in the field of engineering cost, the applicability of BIM technology in the management of transmission and transformation engineering cost is first analysed; then the BIM technology is studied layer by layer from the aspects of graphical calculation, three-dimensional design and full process management Promoting strategies for application of engineering cost management; Finally, from the perspective of policy guidance, industry standards, BIM platform construction, and training of BIM talents, the application guarantee mechanism of BIM technology in transmission and transformation project cost management is proposed, with a view to BIM technology in transmission and transformation projects Provide reference for application promotion in cost management.
