El túnel de la línea: ¿un problema o una solución? Revisión teórica de lo ejecutado respecto lo proyectado

Abstract

The monograph presents the analysis and understanding of the process that has led one of the most visionary projects at the road infrastructure level in Colombia, which has different recognitions for Colombian engineering such as the Line Tunnel. This document compares the design phase with respect to construction from the review of the pre-contractual, contractual and post-contractual stages from a technical and economic context of the aspects for design, construction and auditing, identifying the parameters that affected the feasibility of the project through a comparative analysis; In addition to this, the description of the unforeseen events found thanks to the revision of the contracts and the consultation of secondary sources in order to identify the importance in the planning of the projects from all their stages. According to the above, it was possible to evidence the background of the project, the relevant contracts for the preparation of the studies, designs and construction for the different stages of the project, showing not only delays in the execution of the initial contracts together with their addictions and modifications, but also the over-costs generated by said actions, inadequate risk management, lack of detailed analysis and penalties that were imposed; This makes it possible to emphasize the importance of the correct planning of a project for its efficient execution from a technical and economic context in each of the stages ( pre-feasibility, feasibility, detail, execution, operation) without specifying in any kind of political fact for its proper purpose.
