This paper scans the construction safety management of engineering project from the perspective of safety management of project life cycle, introduces the concept of Design for Safety. Based on secondary development technique of Revit, by virtue of Autodesk Revit, Microsoft Visual Studio, this paper proposes a method which can convert Revit rules of DfS to computer language, then check the design scheme automatically and discern security risk of construction. At last, a specific instance demonstrates the feasibility of this method.
