The projects team at Arrieta Mantilla & Asociados scores highly with clients for its ‘proximity, sensitivity to the business, and openness to discussing issues’. As an infrastructure and public law boutique, the firm is well placed to advise on all key aspects of projects law — from bidding processes and project structuring through to development, concession management and disputes. A go-to industry specialist, senior partner Álvaro Mantilla advises government bodies, and domestic and multinational companies, on public contracts and procurements, public-private partnership (PPP) projects, concession contracts and project finance, among other matters. 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. At senior associate level, Rodrigo Sánchez Pineda is noted for his work in projects-related litigation, while Mónica Cristancho González advises on the structuring of infrastructure projects. Former senior Diana Marcela Díaz left the firm in February 2025.
