||La Plata Cathedral Building, Main church of the capital city of Buenos Aires Province, registered in the nave of San Pedro Basilic given its huge size, placing it among the most important churches in the world. The Executing Unit has decided to split the treatment of the building into three biddings, the first of which will consist in the preservation, restoration and revaluation of the external views of the Cathedral. The second stage will consist in the micropiling and reinforcement of the foundations, and the third and last stage will be the completion of the building. Today's systems technologies permit to store and transmit larger amounts of data. For this reason, the Technical Department of La Plata Cathedral Executing Unit have chosen this means to edit the Public Tender Specifications corresponding to the preservation, restoration, revaluation and completion of this church.
