The 3D information model of deep foundation pit support of the Hunan Broadcasting System Program Production Project is built through using BIM technology, which brings about the pre-construction of prestressed anchor cable, assisting the civil engineers to detect the construction problems earlier and to take relevant measures to avoid risks.The application of BIM technology is especially for identifying and resolving the collision problem of the prestressed anchor cable in the original design drawings, and then the collision report is submitted to the design institute for the optimization design of the drawings.Meanwhile, the 3D visualization disclosure animation is made for powerful technological support to the project completion punctually and highly-qualified.As a result, considerable economic benefits and significant social benefits are achieved.
