The subway system serves the metropolitan area of Mexico City, including some municipalities in the State of Mexico. It is the second-largest metro system in North America, after the New York City Subway. Line 12 of the Mexico City Metro runs from Mixcoac in the west to Tláhuac in the southeast, covering approximately 24.5 kilometers (15.2 miles) with 20 stations. It features a combination of underground, at-grade, and elevated sections.
The construction of Metro Line 12 in Mexico City was undertaken by a consortium of companies led by the Mexican firm ICA, in collaboration with the French company Alstom and the Mexican-Spanish company Carso. I supervised the work carried out by Alstom.
I supervised the installation and testing of materials and equipment related to power, communication, control, and signaling systems.
As part of my daily responsibilities, I took photos, conducted installation checks, and held meetings with contractors. These activities allowed me to prepare detailed daily, weekly, and monthly reports on project progress, material quality, and equipment installation. Additionally, I diligently identified any faults or issues during the installation process.
I create an Excel database based on daily, weekly, and monthly progress reports. This database records pending tasks, encountered problems, and the corresponding dates of attention and completion.
