Ergonomics during the construction of the stations and the drilling of the tunnel in the metro of the city of Quito

Abstract:

The city of Quito capital of Ecuador has a heavy traffic problem, due to its geography that prevents the city from growing, in all the geographical coordinates and can only grow towards the North and the South, reason that extends the times of the trips of citizens within the urban perimeter and is the reason why it was decided to build, the first underground train of the city and the country, work of emblematic civil engineering, which until now is the one of greatest technical difficulty developed in Ecuador, the present The article is responsible for characterizing the ergonomic hazards encountered during the construction of the fifteen stations, as well as the drilling of the twenty-two kilometers of the Quito metro tunnel, using ISO/TR 12295 as an evaluation criterion: 2014, and digitizing the results obtained within computer graphics from a spreadsheet, to facilitate the initial estimation of the Ergonomics aspects encountered throughout the execution of the aforementioned works, this information helps as a baseline for the selection of critical tasks and the subsequent evaluation of ergonomic hazards, the analysis of this work allows us to have an approximation of the ergonomic risks found during the execution of the initial works that concluded in October 2018, as well as the prevention measures used to reduce the health effects of workers.
