Abstract: Considering the features of design and construction of long span steel pipe concrete arch
bridge, a CATIA bridge model adding plug-in and a construction management platform was
developed using CATIA to build a 3D bridge model. This model was applied for the whole process of
planning, design, and construction of the Yelanghe river double line bridge project——a long span
steel pipe concrete arch bridge. Research shows building information modeling (BIM) technology can
be used for guiding the site planning and designing the transportation line during the planning phase
of the project, comparing the design scheme and optimizing the selection in the phase of design, as
well as realizing the statistics of works, preparation of prefabricated components, hoisting of stiff
skeleton, 4D simulation of construction and 3D technical disclosure. Adopting the BIM technology
significantly improved the information construction management level of the bridge and efficiency of
construction. It provides a new management approach of bridge design and construction.

Key words: building information modeling technology, long span steel pipe concrete arch bridge, 3D
model, construction management platform
