GWIC provided Construction Supervision for the requalification of the Quatro Águas area in Tavira, as part of the broader Ria Formosa Requalification and Valorization initiative led by Polis Litoral Ria Formosa, S.A. Covering 34 hectares, this project focused on enhancing public spaces, managing coastal erosion, and regulating occupations along the riverside, while improving road access from the Fishing Port to Quatro Águas. The intervention aimed to balance environmental sustainability with community use, ensuring the preservation of the ecosystem while providing safe, attractive spaces for locals and visitors.
