Identification, Assessment, and Proposal of Mechanical Risk Controls in Urban Road Repaving Infrastructure Projects

This study aims to establish a comprehensive management of mechanical risks that may arise during the construction of infrastructure projects, specifically focusing on the process involved in urban road repaving. The case study selected is the "Repaving of General Rumiñahui Avenue between San Luis Avenue and Santa Clara Street, Quito, Ecuador". The objective is to mitigate various types of work-related accidents resulting from civil construction interventions. Mechanical risks are a significant concern in the construction industry, particularly in activities involving heavy machinery and specialized equipment. Like many other countries, Ecuador has construction-related labor regulations in place. Therefore, the main goal of this study is to identify, assess, and propose a system for controlling mechanical risks in the construction of repaving infrastructure projects to improve working conditions. The assessments of mechanical risks in urban repaving infrastructure projects will be analyzed using the "Colombian Technical Guide GTC 45" methodology. This quantitative and analytical approach applies current regulatory methods to define risk levels. The study will conclude by determining appropriate measures for labor control and the respective management of machinery and tools. These measures encompass preventive actions such as the use of personal protective equipment, appropriate signage, engineering controls, and worker training.
