Bridge inspection in accordance with DIN 1076

Bridge structures must be inspected at regular intervals in accordance with the requirements of DIN 1076 and the Federal Guidelines for the Monitoring of Structural Safety (RÜV) to detect damage at an early stage. In addition to structural durability, the stability and traffic safety of the structure must also be assessed.

As a property owner or property manager, you are responsible for the maintenance, structural integrity, and traffic safety of the civil engineering structures under your jurisdiction. The scope of DIN 1076 includes culverts, tunnels, noise barriers and retaining walls, traffic signal systems, sign bridges, and bridges. Without regular inspections of the structures, the owner may also be held personally liable in the event of damage.

How often must inspections be conducted?

Bridge inspections must be carried out at regular intervals in accordance with the requirements of a standard. This allows damage to be detected early and minimizes the costs required for repairs.

Simple inspections and major inspections are scheduled at intervals of 3 and 6 years, respectively, and must be performed by a qualified engineer. If significant defects or damage are found during this visual inspection, they must be further assessed through special inspections as part of a site-specific damage analysis.

What is inspected and documented?

The condition assessments and the structural characteristics of the bridge must be documented in inspection reports and the bridge logbook. In addition to a visual inspection of all components, the structural inspection according to DIN 1076 includes, for example, the measurement of concrete cover, the random determination of carbonation depth, and the assessment of the degree of corrosion of metal components. As part of more extensive testing, the concrete compressive strength is determined using core samples taken on-site, the total chloride content is measured, and testing for polycyclic aromatic hydrocarbons (PAHs) is conducted.

The structural reports we prepare include a list of the damage encountered as well as an assessment of the current condition regarding durability, structural stability, and traffic safety. If no records are available for older structures, we also recreate the structural logs. For this purpose, we use the SIB-Bauwerke program, which is widely used by administrative bodies and building authorities.
