5. Building information modeling BIM The BIM (Building Information Modeling) is a smart 3D modeling process that enables professionals in architecture, engineering and construction (AEC) to use tools for more efficient planning, design, construction and management of facilities and infrastructure. BIM integrates physical, environmental, commercial and functional data and each of its components, parts and systems. The European Commission makes a procurement recommendation (design services) with the Public Contracts Directive (2014/24 / EU) that requires a Building Information Modeling BIM electronic model within the ToR. Based on the market research (Capterra Construction Management) it is grossly estimated that for the introduction of BIM, the initial investment would be approximately EUR 28,000, and control room cost 100.000 euros. If digital model has been created in the SAP 2000 program, and if the control finds that it is appropriate, cost of BIM model can be reduced. In addition to the costs of introducing SHM and BIM, it is also necessary to plan the room for control rooms.

6. Seismic structural control The seismic bridges insulation is a convenient and economical solution to the seismic protection of bridges and viaducts, and it differs from seismic insulation applied to buildings. The application of seismic insulation to bridges does not require a specific artificial horizontal discontinuity of the construction and applies to constructions whose static classification method already has discontinuity between the columns of the bridge (or the columns of the vaults, the abutments) and the bridge plate. Need for replacement of normal bearings with seismic insulators. Adopting the connections of various seismic technical requirements is conditioned by the large movements of the column pillars. For the last thirty years, a large number of European bridges and viaducts have been equipped with seismic insulation / dissipation systems (seismic protection and monitoring measures). European modern bridges and viaducts are the most numerous types of structures that are protected by seismic insulation from earthquakes. Significant designs depend on: size (price or length) and qualitative constructive complexity. Solving the phenomenon (train - track - bridge), the railway bridge under seismic influence is a complex task. The applications of seismic insulation to the steel bridges to which dynamic vibrations and relative displacements are acting, as well as the movement of an unsteady track (CWR- continuous welded rail) do not apply to constructive damage or collapse.
