Análisis y valoración del sobrecosto en la construcción del proyecto mirador del Jardín P.H. Medellín Antioquia

Abstract

Construction is one of the riskiest sectors of the economy, as many variables influence the viability of projects, especially those related to time and costs. In developing countries, there is a higher variability in delivery times and cost imbalances. The literature mentions that internationally, countries like India, Egypt, and Turkey experience the greatest variations in costs and delays in delivery times (Lozano et al., 2018).When construction projects are presented, it's crucial for companies to develop the capability to identify internal and external factors that affect construction performance. Planning is essential from the initiation stage to the delivery stage because if these factors are not taken into account, financial imbalances can occur during the execution of the project (Cárdenas & Hernández, 2006). In Colombia, affordable and social housing is primarily developed and marketed by private construction companies for households with lower incomes, regulated according to Colombian legislation (Fleischer & Hurtado, 2022). For this research, the Mirador del Jardín project in Medellín, Antioquia, was chosen as the study object. The apartments in this project, classified as priority interest, are destined for beneficiaries of the solidarity fund of the military and police housing development agency, within the Type III housing delivery category, which is intended for military personnel who have experienced a loss of work capacity.

During the development of the Mirador del Jardín project, the contractor experienced a financial imbalance and delays in deliveries. Therefore, this research focuses on the analysis and assessment of cost overruns in the construction of the Mirador del Jardín residential project in Medellín, Antioquia. The aim is to determine the possible factors that affected the project, using valuation methodologies outlined in Resolution 620 of 2008 and other knowledge acquired during the specialization in Appraisals at the Francisco José de Caldas District University. The analysis seeks to provide tools to analyze the possible causes of cost overruns and delays in property deliveries, based on the general hypothesis that the derived cost overruns result from a lack of analysis by the contractor and that the project's development is based on a comprehensive contract in which all design and execution studies were required to be conducted.
