The Barranquilla Airport PPP consists of the expansion and operation of the airport in one of the major cities on the Atlantic coast of Colombia. It involved substantial construction works, including remodelling of the terminal and rehabilitating the runway while the existing airport was still in operation. As this project was the first airport PPP following the passing of the PPP law in 2011, the Procuring Authority adopted lessons learned from this project to inform future procurement. The project has been successful, with the first and most important phase of construction due to finish by the end of 2018. There have been a number of challenges relating to KPIs and their application during the operations phase while construction has been ongoing; and the parties have been able to overcome the challenges by working together.
