Mantilla recently paired up with projects and infrastructure head, Álvaro Mantilla Sánchez, to advise Concesionaria Vial Andina (Coviandina) on the execution of a PPP contract with the National Infrastructure Agency (ANI) for a toll road connecting the southern part of Colombia to Bogotá. The team also draws on the senior experience of Yady Villaquirán Castro, whose broad expertise spans administrative law, infrastructure projects, and energy and natural resources.
