Análisis de Fallas en la Fase Precontractual del Proyecto “Mejoramiento de la malla vial mediante la pavimentación en concreto rígido de las vías urbanas de los municipios de Bahía Solano Y Nuquí, subregión Pacífico norte, en el departamento del Chocó

Abstract

This undergraduate thesis analyzes, through a documentary study of the pre-contractual and contractual phases, the main failures identified in the road improvement project in the municipalities of Bahía Solano and Nuquí, in the department of Chocó. The research is based on the review of contracts, budgets, bidding documents, technical studies, resumes of proposed staff, progress reports, and observations made by the Comptroller General of the Republic. The results show significant weaknesses in the pre-contractual phase, including deficiencies in preliminary studies, inconsistencies in the official budget, and partial compliance with the required experience of the proposed personnel. These shortcomings were reflected in the contractual phase through suspensions, delays, inconsistencies in the economic proposal, changes in project location without proper formalization, and quality problems in the pavement and drainage works. The study concludes that deficiencies in the pre-contractual stage had a direct impact on execution, increasing costs, extending deadlines, and reducing the technical quality of the works. Finally, technical, legal, and administrative recommendations are proposed to strengthen planning, improve the role of supervision and inspection, and ensure greater transparency and efficiency in the execution of public infrastructure projects.
