BrIM (Bridge Information Modeling)
Although the application of building information modeling (bim) in the construction sector is expanding every day, its use in transport infrastructure has still been limited and slow. Integrated civil management (cim) has been used primarily for the operations and management sector. On the other hand, civil information modeling (cim) has focused on virtual 3d modeling of transport infrastructures in the design phase [7].
In this context, industry and academia have developed several studies in the area of cim to investigate its different applications. In this circumstance and in order to complement the research, the purpose of this article is to present a comprehensive review of six uses and applications of bridge information modeling (brim), which is the bim applied to bridge structures, highlighted in academic publications in the last 15 years.
On zigurat’s BIM experts blog in march 2020, some brim apps were discussed. However, in this text it will be possible to find more practical uses and applications, dealt with in academic literature.
1. Accelerated bridge construction (abc)
in abc, bim can be used from conceptual design to construction [8]. The bim application in abc (figure 1) can increase the efficiency and sustainability of buildings by reducing waste throughout the lifecycle. The use of bim can enable complex projects and reduce information requests and change requests, which can provide cost savings of between 5% and 9% during construction [8], contributing to the reduction of rework. Therefore, bim can be used to model the bridge and associated diagrams, perform design analyses as well as plan the elevation of precast concrete elements with self-propelled modular transport vehicles (spmtvs), establishing the surrounding grade to facilitate the transport of the superstructure.Bridge information modeling (BRIM).

2. Structural analysis
the advantages of a bim software used for planning can be combined with those used for structural analysis [5]. In this way, structural position diagrams can be created in the bim model or automatically generate reinforcement drawings based on structural analysis as well as directly exporting the finite element software (fem) calculation values in the form of 3d reinforcement or assisting in analysis globals, for example. Figure 2 presents some possible analyzes and diagrams in bridges working in bim softwares.
