Based on BIM technology, a design and arrangement system of pipeline hangers is developed in this article. Through secondary development of BIM software Revit, this system can calculate the stresses of hangers and determine the separation distance between hangers. After deciding the type of hangers and location, the system can take hangers from hanger database and show on three dimensional pipeline drawing. Construction engineers are able to operate this procedure directly on the pipeline design drawing. It makes up the gap from the design drawing to installation and provides a preparation for refined installation. In addition, the function of material statistics helps designers decide a better scheme and helps engineers prepare materials.
