Cost optimization in the construction of prefabricated buildings by using BIM and finite element simulation

This paper uses patterned structure to study the efficiency improvement of practical application BIM technology, and innovates method based on this. The research focus this is build a new assembly component library model algorithm optimization, improve its use management efficiency, core technology design simulation analysis in construction, give timely feedback experimental information. Analyze existing process, standards methods, propose BIM-based method, change idea from whole elements, for prefabricated components. Taking W as starting point, select components form with complete structure. Adjust optimize model, finally reasonable plan. type product includes production, transportation construction. Prefabricated buildings have obvious advantages, comprehensive benefits are higher than other buildings, technical content relatively high, through innovative modernization level building can be improved. Therefore, basis in-depth investigation development status China's construction industry, studies impact different factors engineering costs, including schemes, modes, etc., large number actual operations cases, so achieve purpose reducing cost improving project income, quality.
