This work of professional sufficiency has the purpose of evidencing the increase in the contractual budget of the approved project, its execution being necessary in order to comply with the scope of the contract. Likewise, it is specified that the work is a modality of Public Private Associations (PPA). The built work is located in the district of Ollachea, province of Carabaya in the region of Puno. The environment of the work is characterized by having a very rugged relief and steep slopes which causes the presence of critical sectors in the course of the highway. Since the existing road was interrupted, two solution alternatives are presented; one on the left bank (tunnel) and another on the right (road and 4 bridges), the latter being approved. During the execution of the project, there are differences with respect to the Detailed Engineering Project (PID), given the lack of greater Engineering details; Likewise, it is specified that these errors come from the basic study carried out. As the work is a PPA modality, it is indicated that the Concessionaire is responsible for Engineering, Procurement, Construction and Maintenance for this case of section 4. Therefore, the Concessionaire carried out insufficient studies, both technical and, for example, they were not analyzed the maximum transport weight of metal structures from Lima to Work, which generates adaptations to the project. Finally, the adaptations to the project occur in the 4 bridges and mean a 12,3% increase in the valued amount compared to the contractual amount approved by the MTC.
