Abstract [en]

Bridges have become an important and common part of the infrastructure worldwide. It has been estimated that the cost of the bridge foundation construction constitutes 30% to 50% of the total bridge cost. Thus efficient and cost-saving construction methods are vital for the construction industry and for the society. For this purpose this report includes an international study of 30 bridges and their foundations, the goal of which tries to identify efficient and cost saving methods for bridge foundations.

Ten case studies from each of North America, Europe and Asia have been included in the report including both piled (deep foundation methods) and spread footing methods.

Large span bridges like cable-stayed bridges and suspension bridges as well as small span bridge have been included in the study. Because of the increasing popularity, special attention has been paid to the so-called integral bridge type. The case studies contain some general information about the bridge, the geological conditions at the bridge site and a brief description of the foundation methods used.

The trend of using BIM in preliminary and detailed design of bridges is discussed in a separate section of the report. Possible advantages for adopting BIM in the design of bridge foundations such as interactive design processes are discussed.

Bridge foundations may have a significant environmental impact including large excavations, hazardous materials, noise and etc. The important environmental impact in connection with the foundation work has been commented in another separate section called life cycle assessment.

Finally the case studies are discussed in the conclusions section. The study, being very limited compared to the numerous bridges being built in the world, anyway gives an insight in the big challenges that are associated with bridge foundations and hopefully may give inspiration to new and efficient ways for the foundation of bridges in the future.
