Lawyers at infrastructure and public law boutique Arrieta Mantilla & Asociados are valued for their ‘capacity for analysis, creativity and consideration’, according to some. The group is distinguished by its focus on representing the full range of project stakeholders, including public-sector entities, concessionaires and construction companies, on the structuring, procurement and performance of contracts. It is particularly active in toll-road concessions, where it leverages a formidable record in handling projects across all five generations of Colombia’s road infrastructure initiatives. Among the names to note, senior partner Álvaro Mantilla is a go-to expert for public contracts and procurement matters, as well as complex project-related disputes. He is acting alongside fellow projects specialist, Álvaro Mantilla Sánchez, to advise Coviandina on its public-private partnership (PPP) contract with the National Infrastructure Agency (ANI) regarding the road corridor connecting the southern part of Colombia with Bogotá. Administrative law partner Yady Villaquirán Castro also has a significant projects dimension to her practice and advised Financiera de Desarrollo Nacional (FDN) on the structuring of the Ranchería-San Juan del Cesar and Triángulo del Tolima irrigation districts. The group also includes senior associate Rodrigo Sánchez Pineda, who impresses with his ’willingness to serve the client’s team’; and transport specialist Diana Marcela Díaz, an August 2023 hire from the Cámara Colombiana de la Infraestructura. Associate Julián González Torres departed in July 2023, as did Ramón Enrique Ramírez in January 2024.
