own Gil Ramírez Dávalos, Commissioner of the Marquis of Cañete, Hurtado de Mendoza, made it consign in the text that was described in the interpretation of the primitive plan of our city. This small street is located in the heart of the city and its Historical Center, between two buildings of great importance: The Cathedral of the Immaculate Conception and the old Seminary called San Luis. Building technology Construction methods The construction of the Cathedral was made based on the original plans, these were designed and drawn by Brother Juan, with small changes that occurred in the building process. The direction of the construction of the Cathedral was in charge of priests and executed by Cuenca artisans and the people in general through the mingas. In addition to the detailed technical specifications in the construction plans, popular knowledge is added as an artisan way of building, with a common sense and a logic acquired by experience, skill and expertise of the workers. The Cathedral used artisan systems typical of the time and place. An example of this is the use of wooden scaffolds joined with ropes to lift the thick and gigantic walls of the building. You can still see holes in the outer walls due to such scaffolding Arches and columns The whole set of arches is based on columns with a cruciform section, that is, with protruding bodies to receive the arches. This applies both to the reinforcing arches adhered to the vaults, as well as to those resting on the domes. The arcs have a highlight in their profile. In the columns, to receive these arcs, we also generated ridges at the vertices. Additionally, in each vertex there are smaller columns of circular section that culminate in the capital. Foundation (engineering) The foundation is of river stone masonry, with lime and sand mortar. The depth of the foundations and columns of the buildings of the building is about seven meters, by the level of the floor of the Crypt. In the Towers, the foundations reach a depth of four meters. This was proved in May 1972, by the excavation carried out by Architect Ramírez, when the terrain was tested. Walls Due to the unevenness of the land on which the Cathedral was based, there is a base on the foundations of the same, in order to equalize the foundations of the building.
