Bogotá’s Metro Line 1 project has finally begun, following 80 years of deliberation. Pix4D assists in the construction of the train depot.

The first metro line project is underway in Bogotá, Colombia. With no existing public transport system, the concept of the “Metro de Bogotá” has been debated for 80 years and is a crucial infrastructure project for the city. Overcoming various socio-political and economic hurdles, a contract was signed in 2019, and construction finally began in 2021 on the first metro line, the “ML1!”

The “Patio Taller” is the train depot, a crucial component of the metro system where trains converge and layover to ensure proper functioning and safety. Xenital, a Bogotá-based civil engineering company, is overseeing the construction, which involves the excavation of 1.2 million cubic meters of earth. They used drones, LiDAR technology, and Pix4D for a topographic survey of the soil. Photogrammetry allowed them to facilitate remote monitoring, tracing, and inspection of projects worldwide, eliminating the need for inspectors and developers to be physically present at the site.

Conventionally, this process takes significantly more time. In the case of the Patio Taller project, analyzing and calculating the soil to be excavated was required daily, and estimating the compensation for this soil was very complex. As a result, the project experienced delays and budgetary setbacks during its development.
