Our experts conduct an examination of the technical condition of railway, road and combined bridge structures. As a result of our work, the customer receives high-quality, reliable and complete information about the technical condition of the facility.

Types of examination

  1. Initial survey of the newly built structure.
  2. Periodic examination.
    As a rule, it is carried out with a frequency of once every 5 years, in order to assess the technical condition of the structure, check the compliance of the structures with the established requirements and make changes to the database.
  3. Diagnostics of bridge structures after major repairs.
    It is carried out in order to clarify the technical condition of the structure after the repair work has been completed, to enter these clarifications into the data bank and to correct the technical passport. Reporting documentation - clarifications in the technical passport of the bridge structure.
  4. Pre-design survey.
    Mandatory inspection before drawing up a technical assignment for the design of repair, overhaul or reconstruction of a bridge structure. It is carried out in order to determine the maintainability of its elements and collect the necessary information for the development of the project, the adoption of the correct strategy for the modernization of the structure.
