Six consortia were pre-qualified to bid initially. Two consortia withdrew during the bidding process, but only Apca Transmimetro and Consorcio Metro de Bogotá, comprising FCC, Spain, and Carso Infraestructura y Construcción, Mexico, submitted final offers. The two offers were evaluated during a 15-month selection process conducted by Konfirma SAS, and Apca Transmimetro was awarded 100 points compared with 94.54 points for Consorcio Metro de Bogotá.

The losing bidder has until October 24 to contest the decision, but Bogota Metro expects to sign the contract in the next 45 days with a view to starting construction in the second quarter of 2020.

The contract will run for 28 years including a 20-year agreement to operate and maintain Line 1. The contract includes CRRC Changchun and Bombardier as sub-contractors to supply the trains. Each train will be 140m long and 2.9m wide with capacity for up to 1800 passengers.

Line 1 has a total length of 23.9km with 16 stations. The elevated line will be 13.5m high (at rail level) and will have an earthquake-resistant structure.
