Execution Quality of Reinforced and Prestressed Concrete Bridges on Federal Roads

The research project "Execution quality of reinforced and prestressed concrete structures on federal highways" was conducted in the 1990s. The current research project based on this preliminary project aims to inspect whether the regulations for execution are implemented successfully in practice and how they have influenced the quality of workmanship. As part of the research project 53 construction site inspections on 19 structures were carried out in less than two years to observe the main stages of execution.
In comparison to the preliminary project a decrease in the number of defects per site visit as well as the "seriousness" of the defects is registered. Planning and design documents were improved. The construction supervision offices have shown considerably better knowledge of applicable regulations. The regulations for execution introduced in 2003 have also been implemented successfully in the bridge construction industry. The deficiencies could have been avoided by implementing the existing rules.
