    Aplicación práctica de la metodología de Project Finance en el proyecto de infraestructura Gran Vía Yuma sector 0 y 9 en Barrancabermeja
    (Universidad EAFIT, 2020) Hoyos Gutiérrez, Marcel Arbey; Mena Abadía, Gilmar Augusto; Restrepo Tobón, Diego Alexander
    Historically, it has been the public sector that has financed infrastructure projects, however, due to government capital deficits and in some cases their lack of experience, there has been a reduction in public spending on infrastructure. Project finance then emerged as an option for the financial structuring of infrastructure projects that involves the creation of a separate special-purpose vehicle to assign, through technically elaborated contracts, the risks to those who are in the best capacity to manage them and, consequently, assigning the rewards based on the risks assumed. The present study intends to apply to a financial model under project finance the financial information of the road infrastructure project Gran Vía Yuma, Barrancabermeja (Colombia), and describing for this specific work what are the advantages or disadvantages of use project finance versus corporate finance.

    “DIMCUNET” Programa de cálculo para el dimensionamiento de cunetas de recolección de aguas lluvias, en vías urbanas y carreteras
    (Universidad EAFIT, 2021) Ramos Rivera, Dina Marcela; Marbello Pérez, Ramiro Vicente
    The National Roads Institute (INVIAS, for its acronym in Spanish) presented the Road drainage manual, document used as a guide for the design of hydraulic structures related to road infrastructure. It presents and recommends for Colombia the design for ditches with the triangular geometric section for being the most practical, simple to build and for which you need less area. The manual also presents other geometric sections, but without the corresponding design equations for each type of ditch, leaving the sizing of these structures at the discretion of the designers. Some professionals and consulting firms commonly use spreadsheets to perform these calculations. This implies significant work for the use to understand, establish the validity of each programmed cell, verify the relevance and applicability of these calculations, with the motivation of preventing these applications from becoming black box models. Not to mention that aspects such as hypotheses, limitations, restrictions are not appreciable in this type of document. For this reason, it is necessary to implement a software that allows to optimize time and at the same time an application that has the design equations for different forms of cross sections of ditches.
