The present investigation seeks to propose a technical document that contemplates the necessary criteria to be taken into account in the pre-design and construction of caissons in bridges. The realization of an analysis of basic studies of different bridge projects with foundations with caissons and a validation of the research under the expert judgment methodology allowed to propose different criteria and recommendations that allow to decide the characteristics of the caissons to be implemented and that try to reduce the risks in the construction process of open and pneumatic caissons. This technical document arises from the need for scarcity of information in manuals and national standards to define the use of caissons. In the year 2017, many bridges collapsed due to the strong levels of scour caused by the great floods caused by the El Niño Phenomenon. These bridges failed because they did not have the adequate foundation to withstand the circumstances already described and that is why the correct definition of the foundation to be used is important. Regarding the content of the technical document, you can observe definition criteria according to the level of scour and according to the type of soil. For example, if our project is affected by a total scour of more than two meters, it is recommended to use caissons, otherwise a surface foundation would suffice. On the other hand, measures are also proposed to improve or solve problems during construction such as the control of leveling in the subsidence by means of appropriate equipment to avoid crashes and actions that allow us to recover the verticality of the structure. Finally, it was concluded that the basic studies are essential as a starting point to evaluate the pre-design criteria and define the type of caisson to be used according to the type of soil, its characteristics and those of the superstructure to be received. In addition, it must be considered that this type of infrastructure requires skilled labor.
