Extensive inspection of every component from touch- ing distance, damage and deterioration assessment acc. to RI-EBW-PRÜF, leading to the condition rating of the entire structure. Needs for maintenance, clean- ing, repairs or additional inspections are identified, recommendations for special inspections are given.


6 years, 3 years after main insp.

Visual inspection of every component without viewing equipment. The damage and defects identified in the major inspection are investigated.


When needed

Follows major events affecting the condition of the structure. The extent is determined on a case-by-case basis.

Regulatory requirements

When needed

Machinery and electrical equipment are inspected in accordance with other regulations and standards

The RI-EBW-PRÜF ”Guideline for Standardised Registration, Processing and Analy- sis of the Results of Inspection in Accordance with DIN 1076”, 1998 edition 3 contains rules for a simple and standardised logging of the results of inspection. The standard- ised procedure allows structural conditions to be rated in accordance with the various criteria and the inspection results to be linked with the construction-related data in accordance with ASB. The technique of condition assessment is characterised by a detailed damage and condition assessment in accordance with standard criteria. As part of inspection, every single damage is evaluated separately in terms of its effect on the stability, traffic safety and durability of the structure and recorded by SIB- Bauwerke. This damage evaluation is used as a basis for automatically calculating the condition grade for the entire structure. The extent of damage and the number of individual occurrences of damage is also considered in this process. RI-EBW-PRÜF contains detailed definitions of assessment criteria and sample catalogues for a standard evaluation of damage.

Inspection results form the basis for all maintenance planning activities. At state level in most cases construction agencies are in charge of performing inspections. The findings obtained from the bridge inspections and additional object-related analyses are used to prepare the maintenance concepts at the construction agencies. The preparation of performance specifications, announcements/allocations as well as the processing and documentation of projects are also performed here. Annual construc- tion programs are prepared by the agencies and co-ordinated with the responsible, higher-level authorities. Prioritisation is performed on the basis of the existing sever- ity of damage, operational and traffic-related circumstances and available financial resources. Cost estimates prepared by the agencies generally result in the require- ment reports for the Federal Ministry.

For controlling purposes, the states annually supply the Federal Ministry with aver- age structural condition grades classified in accordance with structural type. The states have to report a medium-term requirement program for maintenance and an annual program plan for the following year. These reports provide the federal authori- ties with important information concerning major upcoming repair measures and the corresponding resource requirements.
