The large projects team at full-service outfit Morales & Besa particularly stands out for its infrastructure credentials in relation to project development, acquisitions, financing, contracts, regulatory issues and related litigation. The multidisciplinary group’s recent track record includes mandates involving airports, solar power plants, PPP projects, toll roads, and renewables. The practice is also increasingly expanding its market share of engineering, procurement and construction matters. Heading the practice, Carlos Silva’s experience covers the gamut of project issues, from structuring to development, financing and M&A work; real estate and construction department leader Macarena Laso assists with corporate transactions, along with the structuring, acquisition and financing of public infrastructure projects; and Myriam Barahona and Eugenio Besa are both project finance experts.
