Design and Construction Management of Expressway Interchange Based on BIM Technology
The traditional CAD 2D design mode has some problems in application,such as 2D design is not intuitive enough,the design details are not well studied,the drawings are not corresponding,the design coordination is not unified,the cooperation degree is low and so on.Compared with the traditional 2D design,BIM can control the drawing quality and cooperation flow of the project with the help of 3D model and model data.Based on this,taking the interchange project of ancient city interchange of Hehui Expressway as an example,introducing BIM technology into the project to play the role of visual guidance construction,the efficiency can be increased by about 15%,and the material comprehensive loss rate can be reduced by 20%.
