At present, China is vigorously promoting the information construction in the field of new infrastructure engineering, and the building information model is an important carrier of the information construction. Based on the classification of the special scheme literature of railway related engineering line reinforcement, the construction method of line safety reinforcement is summarized, the engineering structure is decomposed, and the parametric family library is established. The construction of 3D information model of actual engineering project is cited to verify the feasibility of parametric modeling of infrastructure engineering based on the Revit platform, which lays the front-end foundation for BIM's fine management in the whole life cycle of such projects.
