Introduction The operational reliability of metal products is controlled by the operating conditions [1-5], the nature of the material, the type and mode of its technological processing [6-9] and, ultimately, is due to the structure and mechanical properties of the materials used [10-12], which is provided by the optimization of technological processes [13-15].

Application of BIM in Construction and Analysis of Obstacles Hong Tang 1, a and Teng Long 2, b College of urban construction, Wuhan University of Science and Technology, Wuhan, Hubei, China College of urban construction, Wuhan University of Science and Technology, Wuhan, Hubei, China a564638938@qq.com,b296537192@qq.com Keywords: BIM implementation; 3D model; Management system; Obstacle analysis Abstract: This paper mainly focus the on application of BIM in construction and obstacles existing in development of BIM.
According to the construction difficulties of some project, the authors established the 3D model of the project, derived the 2D construction drawings and calculated the quantities of the materials by softwares based on BIM technology.
We can also get abundant information such as the sizes, surface material of each component and the internal reinforcement configuration etc.
In addition, calculating quantities through 2D drawings is of high error ratio which is not conducive to arrange the materials entry plan and have impacts on controlling cost.
