Many projects are being developed in the country and many of them have a prefabricated plant, but few will require a volume of prefabricated elements such as elevated railway viaducts, for example the Line 1 of the Lima Metro. The manufacturing process of prefabricated beams that are part of the Line 1 viaduct was carried out in the Prefabricated Plant, where the assembly of the reinforcements, the tasks of welding and mooring, prestressing and casting were carried out. The prefabricated beams were moved from the plant to the different points of the work at night, thus, the construction of the viaduct had an industrial process as far as the beams and other prefabricated elements used (pre-slabs, gutters, etc.). The rapid construction of the Line 1 viaduct was a product of these prefabricated concrete elements, which allowed the advance of the Proceres de la Independencia Avenue without interrupting traffic or disturbing neighbors. Having this experience of the prefabricated of the Line 1, this thesis tries to cover all the process followed, from the supply of materials, manufacturing, transport to work, as well as the process of quality control applied to the process of prestressed beams. Finally, a compendium of the above explained is made to be able to converge all the ideas and to have an idea of the magnitude of the project. Based on these experiences, production costs were estimated in the cities of Arequipa and Trujillo. As something additional to these issues, the manufacture of head beams is presented as an innovative element in this type of works.
