Application of 3D Bridge Information Modeling to Design and Construction of Bridges

Building information modeling (BIM) is a new technology in bridge construction industry. 3D models can provide perfect numerical expression of drawings from design results. 3D information models for bridge structures improve design quality in terms of accurate drawings, constructability and collaboration. However, there are lots of obstacles to apply these techniques to actual bridge projects. In this paper, extensible information schema for bridges is proposed to enable interoperability between different design and construction processes. From the planning stage of a bridge construction project to the construction stage, the proposed bridge information models were applied to enhance current practices. Digital mock-up, parametric modeling, 4D and 5D simulation were conducted. From several applications for four years, a design guideline of 3D information models was suggested. It is essential to change current processes for the effective use of BIM techniques in bridge construction industry.
