Communications Construction News reported the First Metro Line of Bogota project (PLMB) in Colombia with a four-page special edition.

On May 12, the Communications Construction News reported the First Metro Line of Bogota project (PLMB) in Colombia with a four-page special edition, which is invested and operated by CRBC, a subsidiary of CCCC.
As the largest municipal project in the history of Colombia, the PLMB is a model of win-win cooperation between China and Colombia. After the completion of the project, it will greatly improve the traffic and livelihood of Bogota people and fulfill the 70-year dream of Bogota citizens for a subway.
The PLMB is designed to have a total length of 23.96 kilometers, including the construction of 16 stations and the procurement of 30 metro cars, using the highest level automated driverless system, the UTO fully automated driverless system. Its entire elevated bridge goes through the downtown of the city.
In August 2021, the main construction of the PLMB officially started. In spite of the severe epidemic, the PLMB has achieved many milestones. In order to build a green, energy-saving, efficient and safe urban transportation rail, the CRBC team has strived for technical excellence, advancing the construction progress while ensuring the high quality of the project.
The project attaches importance to cultivating local talents and providing a broad development platform for employees. As of February this year, the project has more than 250 employees in service, of which more than 75% are local and international employees, generating a total of more than 1,200 direct and indirect jobs. After the project is opened, it will provide more than 17,000 new jobs for the areas along the line.
Currently, the main structure of the No. 72 tunnel of the PLMB is under construction, laying a solid foundation for the following work.
Since this April, the project team has overcome the adverse effects of the recent heavy rain on operations, and still maintained a construction speed of 4,000 meters per day, including CMC foundation treatment, platform construction and backfill, achieving phased progresses. In the future, the project team will continue to overcome one section after another, striving to complete the project earlier.
Bogota citizens are looking forward to the opening of the metro, and the topics related to the metro are always very popular on social media. The PLMB is expected to save 839,000 hours of daily travel time and reduce more than 700 traffic accidents per year. The subway will gradually replace private cars and buses, and is expected to reduce carbon dioxide emissions by 171,000 tons and gasoline consumption by 19 million gallons per year. In addition, the implementation of the PLMB can accumulate valuable practical experience for the construction of more infrastructure projects in the future.
